Abstract
Description
Technical Field
[0001] This application relates to the field of dust collector filter cleaning technology, and more specifically, to a dust collector filter cleaning device and a filter cleaning control method. Background Technology
[0002] In the indium recovery production process, flue gas dust removal is a crucial step in ensuring the purity of indium extraction and preventing dust pollution of equipment and the environment. High-temperature dust collectors, as core dust removal equipment, are widely used in this process. The indium recovery process generates high-temperature flue gas containing a large amount of dust particles. The flue gas temperature is typically maintained between 50 and 120°C, and the dust contains indium-related impurities, requiring filtration by a high-temperature dust collector. Existing high-temperature dust collectors mostly employ cartridge-type filtration structures, with filter materials primarily made of high-temperature resistant metals, fiberglass, or paper to adapt to the high-temperature flue gas conditions. To extend the filter cartridge's lifespan and maintain stable filtration efficiency, current technologies typically use pulse purging, overall gas purging, or water washing to clean and regenerate the filter cartridge. By introducing gas or cleaning fluid into the surface or interior of the filter cartridge, dust impurities adhering to the surface and folds are removed, enabling the filter cartridge to be reused and meeting the production requirements for long-term continuous dust removal of indium recovery flue gas.
[0003] Existing high-temperature dust collectors struggle to achieve efficient cleaning of their filter elements, severely impacting filter regeneration and the overall operational efficiency of the dust collector. Current cleaning methods often employ integral blowing or rinsing, resulting in uneven surface cleaning of the filter elements. Long-term accumulation of this unevenness significantly reduces filtration efficiency and lifespan. Furthermore, existing cleaning parameters lack scientific basis, easily leading to under- or over-cleaning. Insufficient cleaning results in dust residue affecting dust removal efficiency, interfering with subsequent indium extraction processes, and further increasing the operational costs of indium recovery production. This ultimately fails to meet the cleaning requirements for indium recovery flue gas dust removal. Summary of the Invention
[0004] The purpose of this application is to provide a dust collector filter element cleaning device and a filter element cleaning control method, which solves the technical problem of difficulty in achieving efficient cleaning of dust collector filter elements and achieves the technical effect of efficient cleaning of dust collector filter elements.

[0006] In one possible implementation, a zoned purging nozzle group is further included. This group is used to switch between purging nozzle groups based on preliminary purging parameters to purge dust from different pleated areas of filter cartridges of different specifications. The different specifications of filter cartridges include those with different pleat densities and sizes. A pollution level classification component is also used to determine the corresponding pollution level of different specifications of filter cartridges based on the pressure difference and dust adhesion on both sides, and to determine different preliminary purging parameters for filter cartridges of the same specification and pollution level. These preliminary purging parameters include purging pressure, purging flow rate, purging frequency, and the purging nozzle group corresponding to the zoned purging nozzle group. A gas purging component is also used to control the zoned purging nozzle group, applying different preliminary purging parameters to filter cartridges of the same specification and pollution level. The filter element to be cleaned undergoes a purging and dust removal test. The purging control component is also used to determine the product of the pressure difference change and the dust adhesion change corresponding to the purging and dust removal test, as the dust removal effect index; it is also used to determine the product of the purging pressure, purging flow rate, and purging frequency corresponding to the purging and dust removal test, as the dust removal input index; it is also used to determine the quotient of the dust removal effect index and the dust removal input index, as the cleanliness index corresponding to the purging and dust removal test; and it is used to determine the maximum cleanliness index of the filter element of the same specification with the same pollution level for the purging and dust removal test under different preliminary purging parameters, and to determine the purging nozzle group corresponding to the maximum cleanliness index as the optimal purging nozzle group and the preliminary purging parameters corresponding to the maximum cleanliness index as the optimal preliminary purging parameters; and to purify the filter element of the same specification with different pollution levels according to the optimal purging nozzle group and the optimal preliminary purging parameters.
[0007] In another possible implementation, the dust adhesion monitoring component is also used to detect the amount of dust residue deep in the folds of the filter element to be cleaned in the high temperature and high pressure dust collector online, and to detect the change in the amount of dust residue deep in the folds of the filter element to be cleaned before and after the gas purging component performs the purging dust removal test; the zoned purging nozzle group also includes a purging angle adjustment component, which is used to switch the purging nozzle group and the purging nozzle group according to the preliminary purging parameters, so as to purify and remove dust from different fold areas of different specifications of filter elements to be cleaned according to different purging angles; The components include filter elements of different specifications, such as those with different pleat densities, sizes, and pleat structures. The pollution level classification component is also used to determine the corresponding pollution level of filter elements of different specifications based on the pressure difference and dust adhesion on both sides, and to determine different preliminary purging parameters for filter elements of the same specification but with the same pollution level. These preliminary purging parameters include purging pressure, purging flow rate, purging frequency, and purging angle, where the purging angle is the angle between the purging direction and the groove extension direction of the filter element pleats. The gas purging assembly is also used to control the zoned purging nozzle group, performing purging and dust removal tests on filter cartridges of the same specification and pollution level according to different preliminary purging parameters; the purging control assembly is also used to determine the product of the pressure difference change, dust adhesion change, and dust residue change in the folds corresponding to the purging and dust removal test at different purging angles, as a dust removal effect index; it is also used to determine the product of the purging pressure, purging flow rate, and purging frequency corresponding to the purging and dust removal test at different purging angles, as a dust removal input index; it is also used to determine the product of the purging pressure, purging flow rate, and purging frequency corresponding to the purging and dust removal test at different purging angles.

[0008] In another possible implementation, a filter life monitoring component is also included. This component is used to obtain the usage time of filter cartridges of different specifications to be dusted, and to determine the pressure difference change weight, dust adhesion change weight, and dust residue change weight in the folds based on the usage time of the filter cartridges of different specifications. The purging control component is also used to determine the sum of the products of the pressure difference change value and the pressure difference change weight, the dust adhesion change amount and the dust adhesion change weight, and the dust residue amount in the folds and the dust residue change weight corresponding to the purging dust removal test at different purging angles, as a dust removal effect index.
[0009] In another possible implementation, multiple dust removal filtration channels are also included, each containing multiple identical filter elements to be cleaned for dust removal filtration. The purging control component is further used to acquire the preliminary cleaning and purging parameters, actual channel cleanliness index, and preset channel cleanliness index corresponding to different dust removal filtration channels in the purging dust removal test. The purging control component is also used to determine the difference between the preset channel cleanliness index and the actual channel cleanliness index corresponding to different dust removal filtration channels, and the ratio of the preset channel cleanliness index to the actual channel cleanliness index, as the cleanliness index deviation ratio corresponding to different dust removal filtration channels. The 1.5 power of the cleanliness index deviation ratio is determined as the cleaning and purging parameter adjustment ratio. The purging control component is also used to increase the purging pressure, purging flow rate, and purging frequency according to the cleaning and purging parameter adjustment ratio to obtain the adjusted cleaning and purging parameters corresponding to the dust removal filtration channels. The purging control component is also used to control the gas purging component to purge the filter elements according to the adjusted cleaning and purging parameters.
[0010] In another possible implementation, multiple filter element deformation monitoring components are also included. These components monitor the actual filter element deformation in the dust removal filtration channel. The purging control component is also used to obtain the adjusted cleaning and purging parameters, the preset filter element deformation, and the preset safety deviation index corresponding to the adjusted cleaning and purging parameters for different dust removal filtration channels during the purging dust removal test. The purging control component is also used to determine the difference between the actual filter element deformation and the preset filter element deformation, and the ratio of the preset filter element deformation, as the actual safety deviation index corresponding to the dust removal filtration channel. When the actual safety deviation index is greater than or equal to the preset safety deviation index, the purging control component reduces the purging pressure of the adjusted cleaning and purging parameters according to the adjustment ratio of the cleaning and purging parameters, thus obtaining the deformation-controlled cleaning and purging parameters. The purging control component is also used to control the gas purging component to purge the filter element according to the deformation-controlled cleaning and purging parameters.
[0011] In another possible implementation, the purging control component is also used to obtain the deformation control channel cleaning index corresponding to the dust removal of the filter element in the dust removal filter channel according to the deformation control cleaning purging parameters; the purging control component is also used to determine the difference between the preset channel cleaning indices corresponding to different dust removal filter channels, the ratio of the deformation control channel cleaning index to the preset channel cleaning index, as the cleaning index deviation ratio corresponding to different dust removal filter channels; the purging control component is also used to issue a prompt message for replacing the filter element in the dust removal filter channel when the cleaning index deviation ratio is greater than or equal to the preset cleaning index deviation ratio.
[0012] In another possible implementation, the purging control component is also used to obtain the filter cartridge usage time, historical cleaning times, cumulative deformation, and optimal channel cleanliness index of the dust removal filtration channel when the cleanliness index deviation ratio is less than the preset cleanliness index deviation ratio; wherein, the cumulative deformation is the cumulative value of the deformation of the filter cartridge in the dust removal filtration channel during the historical cleaning process; the purging control component is also used to determine the predicted value of the remaining life of the filter cartridge in the dust removal filtration channel based on the filter cartridge usage time, historical cleaning times, cumulative deformation, and optimal channel cleanliness index through an empirical value table.
[0013] In another possible implementation, a channel switching component is also included, which is used to switch the dust filter channel with a remaining life prediction value less than a preset remaining life prediction value to a dust filter channel with a remaining life prediction value greater than or equal to the preset remaining life prediction value in series.

[0022] The existing high-temperature dust collectors lack scientific basis for setting cleaning parameters when cleaning filter elements, which can easily lead to insufficient or excessive cleaning and cannot meet the filter element cleaning requirements for indium recovery flue gas dust removal.
[0023] Based on the above reasons, this application provides a dust collector filter element cleaning device, including: a differential pressure sensor for detecting the pressure difference between the two sides of the filter element to be cleaned in a high-temperature and high-pressure dust collector, and for detecting the change in pressure difference between the two sides of the filter element before and after the gas purging module performs a dust removal test; a dust adhesion monitoring component for detecting the amount of dust adhered to the filter element in the high-temperature and high-pressure dust collector, and for detecting the change in dust adhesion of the filter element before and after the gas purging module performs a dust removal test; a pollution level classification component for determining the corresponding pollution level of the filter element based on the pressure difference and dust adhesion, and for determining different preliminary purging parameters for filter elements of the same pollution level; and a gas purging component for... The dust removal test is performed on filter cartridges of the same pollution level using different preliminary purging parameters. A purging control component is used to determine the product of the pressure difference change and the change in dust adhesion corresponding to the purging test, as the dust removal effect index; to determine the product of the purging pressure, purging flow rate, and purging frequency corresponding to the purging test, as the dust removal input index; to determine the quotient of the dust removal effect index and the dust removal input index, as the cleanliness index corresponding to the purging test; and to determine the maximum cleanliness index for purging tests on filter cartridges of the same pollution level using different preliminary purging parameters, and to determine the preliminary purging parameters corresponding to the maximum cleanliness index as the optimal preliminary purging parameters; and to perform purging on filter cartridges of different pollution levels according to the optimal preliminary purging parameters. This embodiment of the application can achieve precise purging configuration for filter cartridges with different pollution levels, avoiding over-purging or under-purging caused by uniform parameters, and significantly improving the targeting and effectiveness of dust removal operations.
[0024] In some scenarios, the dust collector filter cleaning equipment of this application embodiment can be applied to the dust removal and cleaning of filter elements in high-temperature flue gas dust collectors at 50~120℃, which can improve the dust removal effect of high-temperature flue gas filter elements.
[0025] The following describes in detail, with specific examples, a dust collector filter cleaning device provided in the embodiments of this application.
[0026] Figure 1 A schematic diagram of the control structure of the first type of dust collector filter cleaning equipment provided in this application embodiment is shown below. Figure 1 As shown in the embodiment of this application, a dust collector filter element cleaning device is provided, including a differential pressure sensor 11, a dust adhesion monitoring component 12, a pollution level classification component 13, a gas purging component 14, and a purging control component 15. The differential pressure sensor 11, the dust adhesion monitoring component 12, the pollution level classification component 13, the gas purging component 14, and the purging control component 15 cooperate with each other to remove dust from the dust collector filter element.
[0027] In some implementations, the differential pressure sensor 11 is used to detect the pressure difference between the two sides of the filter element 121 to be cleaned in the high temperature and high pressure dust collector, and to detect the change in the pressure difference between the two sides of the filter element to be cleaned before and after the gas purging module performs the purging dust removal test.
[0028] In this implementation, a differential pressure sensor 11 can be configured inside the high-temperature and high-pressure dust collector, and detection points can be set on both sides of the filter element to be cleaned. The pressure data of the two points can be collected by the differential pressure sensor 11, and the pressure difference between the two sides of the filter element to be cleaned can be calculated to provide basic data for subsequent pollution level determination.
[0029] It should be noted that the differential pressure sensor 11 can obtain the pressure values of the pressure sensors respectively set on both sides of the filter element, and obtain the pressure difference value by subtracting the two pressure values.
[0030] For example, a first pressure sensor can be arranged on the air inlet side of the filter element and a second pressure sensor can be arranged on the air outlet side. The differential pressure sensor 11 receives the detection data from the two sensors and directly calculates the pressure difference between the two sides.
[0031] In this implementation, the pressure difference between the two sides of the filter element 121 to be cleaned can be recorded once before the gas purging assembly 14 starts the purging dust removal test. After the purging test is completed, the pressure difference can be recorded again. The pressure difference sensor 11 calculates the difference between the two recorded values to obtain the pressure difference change value.
[0032] It should be noted that the detection of pressure difference changes also relies on pressure sensors on both sides of the filter element to collect the pressure difference before and after purging, and then calculate the change in the two differences.
[0033] For example, the pressure difference between the two sides of the filter element is detected as the initial value before purging, and the pressure difference is detected as the final value after purging. The differential pressure sensor 11 calculates the difference between the initial value and the final value to obtain the pressure difference change value corresponding to this purging.
[0034] In some implementations, a dust adhesion monitoring component is also included, which is used to detect the amount of dust adhered to the filter element to be cleaned in the high-temperature and high-pressure dust collector, and to detect the change in dust adhesion of the filter element to be cleaned before and after the gas purging module performs the dust removal test.
[0035] In this implementation, a dust adhesion monitoring component 12 can be configured to collect data from the filter element to be cleaned, and obtain the total weight of dust adhering to the filter element through preset calculation logic, providing a core basis for determining the pollution level.
[0036] It should be noted that the dust adhesion monitoring component 12 can use a weighing method to detect the dust adhesion amount. First, obtain the weight of the clean filter element, and then obtain the weight of the filter element 121 to be dusted. The difference between the two is the dust adhesion amount.
[0037] Figure 2 This is a front cross-sectional view of the dust adhesion monitoring component in the first type of dust collector filter cleaning equipment provided in this application embodiment. Figure 3 A left-side view of the dust adhesion monitoring component in the first type of dust collector filter cleaning equipment provided in this application embodiment, as shown in the diagram. Figure 2 and Figure 3 As shown, a miniature high-temperature resistant weighing sensor 123 can be integrated into the fixed mounting base 122 of the filter element 121 to be cleaned. The bottom of the filter element 121 to be cleaned is provided with a dust removal port that can be opened or closed and sealed for discharging dust. The two ends of the fixed mounting base 122 of the filter element 121 to be cleaned can be connected by a flexible pipe 124 to avoid the pipe affecting the weight of the filter element 121 to be cleaned. The weight of the clean filter element without dust can be weighed first by the miniature high-temperature resistant weighing sensor 123, and then the original mounting structure of the filter element can be weighed by the miniature high-temperature resistant weighing sensor 123. Each filter element is independently configured with a weighing unit to avoid weight interference between multiple filter elements.
[0038] For example, the total weight of the filter element and dust before purging is the initial total weight, and the total weight after purging is the final total weight. The dust adhesion monitoring component 12 calculates the difference between the initial total weight and the final total weight to obtain the change in dust adhesion corresponding to this purging.
[0039] In some implementations, a pollution level classification component is also included. This component determines the corresponding pollution level of the filter element to be cleaned based on the pressure difference across the filter element and the amount of dust adhering to it. It is also used to determine different preliminary purging parameters for filter elements of the same pollution level. These preliminary purging parameters include purging pressure, purging flow rate, and purging frequency.
[0040] In this implementation, the data collected by the differential pressure sensor 11 and the dust adhesion monitoring component 12 can be transmitted to the pollution level classification component 13. The pollution level classification component 13 has a preset judgment rule, which, combined with the numerical range of the two data, determines the pollution level of the filter element to be cleaned.
[0041] It should be noted that the pollution level classification component 13 can determine the pollution level through an empirical value table. The empirical value table pre-sets the pollution levels corresponding to different pressure difference values and dust adhesion ranges. The component matches the detection data with the ranges in the table to obtain the corresponding level.
[0042] For example, the empirical value table sets the filter element to a light pollution level when both the pressure difference and dust adhesion are in the low range; and a heavy pollution level when both data are in the high range.
[0043] In this implementation, multiple sets of different purging parameter combinations can be preset for filter cartridges of the same pollution level through the pollution level classification component 13. Each set of parameters includes parameter values in three dimensions: purging pressure, purging flow rate, and purging frequency, providing different parameter options for subsequent purging tests.
[0044] It should be noted that the pollution level classification component 13 can determine different preliminary purging parameters for filter elements of the same pollution level based on the empirical value table. The empirical value table has multiple sets of verified purging parameter combinations preset for each pollution level.
[0045] For example, for filter cartridges with a moderate level of contamination, three different combinations of purging pressure, flow rate, and frequency are pre-set in the empirical value table as preliminary purging parameters for subsequent testing.
[0046] For example, a set of preliminary purging parameters includes a specific purging pressure value, a corresponding range of purging flow rate values, and a set purging frequency value. These three parameters together constitute the complete purging control parameters.
[0047] In some implementations, a gas purging assembly is also included, which is used to perform purging and dust removal tests on filter cartridges of the same pollution level according to different preliminary purging parameters.
[0048] In this implementation, multiple sets of preliminary purging parameters output by the pollution level classification component 13 can be sequentially transmitted to the gas purging component 14. The gas purging component 14 and the filter element 121 to be cleaned are fixed independently to facilitate individual weighing of the filter element 121. The gas purging component 14 is equipped with multiple nozzles 141. The gas purging component 14 adjusts its purging pressure, flow rate and frequency according to each set of parameters to carry out purging and dust removal tests on the filter elements 121 to be cleaned one by one for the same pollution level.
[0049] It should be noted that the gas purging assembly 14 can be configured with a separate drive assembly to drive the gas purging assembly 14 to rotate, so as to drive the gas purging assembly 14 to perform a comprehensive purging of the dust filter element 121 to be cleaned.
[0050] In some implementations, a purging control component 15 is also included. This component determines the product of the pressure difference change and the change in dust adhesion corresponding to the purging dust removal test, as the dust removal effect index. The purging control component 15 also determines the product of the purging pressure, purging flow rate, and purging frequency corresponding to the purging dust removal test, as the dust removal input index. Furthermore, the purging control component 15 determines the quotient of the dust removal effect index and the dust removal input index, as the cleanliness index corresponding to the purging dust removal test. It is also used to determine the maximum cleanliness index for different preliminary purging parameters when performing purging dust removal tests on filter elements of the same pollution level, and to determine the preliminary purging parameters corresponding to the maximum cleanliness index as the optimal preliminary purging parameters. Filter elements of different pollution levels are then purged according to the optimal preliminary purging parameters.
[0051] In this implementation, the pressure difference change value detected by the differential pressure sensor 11 and the dust adhesion change value detected by the dust adhesion monitoring component 12 can be transmitted to the purging control component 15. The purging control component 15 performs a multiplication operation on these two values, and the result is the dust removal effect index of the corresponding purging test.
[0052] It should be noted that the dust removal efficiency index is calculated by multiplying the change in pressure difference and the change in dust adhesion. The two indicators together reflect the dust removal effectiveness of the purging test.
[0053] For example, the pressure difference change value in a certain purging test is a first value, and the change in dust adhesion is a second value. The purging control component calculates the product of the first value and the second value to obtain the dust removal effect index of this test.
[0054] In this implementation, the purging pressure, purging flow rate, and purging frequency parameters used in this purging test can be transmitted to the purging control component 15. The purging control component 15 performs a multiplication operation on these three parameter values, and the result is the dust removal input index for the corresponding purging test.
[0055] It should be noted that the dust removal input index is calculated by multiplying the purging pressure, purging flow rate, and purging frequency, and quantitatively reflects the scale of resources invested in this purging test.
[0056] In this implementation, the calculated dust removal efficiency index and dust removal input index can be transmitted to the purging control component. The component performs a division operation on these two values, and the result is the cleanliness index of the corresponding purging test, which is used to evaluate the dust removal efficiency of the parameter combination.
[0057] It should be noted that the cleanliness index is calculated by dividing the dust removal efficiency index by the dust removal input index, and comprehensively reflects the dust removal effect achieved per unit of resource input.
[0058] In this implementation, the cleanliness indexes corresponding to each group of preliminary purging parameters under the same pollution level can be summarized. The values of all cleanliness indices are compared by the purging control component 15, and the cleanliness index with the largest value is selected. The preliminary purging parameters corresponding to the cleanliness index are then determined as the optimal preliminary purging parameters under the pollution level.
[0059] It should be noted that, for filter elements of the same pollution level, the cleanliness index of multiple sets of preliminary purging parameters is sorted, and the parameter corresponding to the highest cleanliness index is selected as the optimal preliminary purging parameter to achieve the best balance between efficiency and investment.
[0060] This implementation utilizes a differential pressure sensor to detect the pressure difference across the filter element to be cleaned, a dust adhesion monitoring component to detect the amount of dust adhering to the filter element, and a pollution level classification component to determine the pollution level of the filter element based on the above two data. Then, different preliminary purging parameters are set for filter elements of the same pollution level. The preliminary purging parameters include purging pressure, purging flow rate, and purging frequency. The gas purging component conducts purging dust removal tests according to different preliminary purging parameters. The purging control component selects the optimal preliminary purging parameters for the corresponding pollution level by calculating the cleanliness index. Finally, the filter element of the corresponding pollution level is purged according to these parameters. This enables precise purging configuration for filter elements with different pollution levels, avoiding over-purging or under-purging caused by uniform parameters, and significantly improving the targeting and effectiveness of dust removal operations.
[0061] This implementation method calculates the quotient of the dust removal efficiency index and the dust removal input index as the cleanliness index, thereby evaluating the dust removal efficiency of different purging parameters. This monitoring and evaluation method achieves multi-dimensional quantitative evaluation of dust removal efficiency, avoiding the one-sidedness of a single indicator, and providing accurate and reliable data support for purging parameter optimization. This control logic can minimize purging resource input while ensuring dust removal efficiency, achieving the optimal balance between dust removal efficiency and resource consumption, and effectively improving the economy and practicality of equipment operation.
[0062] Figure 4 A left-side view of the dust adhesion monitoring component in the second type of dust collector filter cleaning equipment provided in this application embodiment, as shown in the diagram. Figure 4 As shown, in some implementations, a partitioned purging nozzle group 16 is also included. The partitioned purging nozzle group 16 is used to switch the purging nozzle group 161 according to the preliminary purging parameters to purge and remove dust from different pleated areas of the filter elements 121 of different specifications. Among them, the filter elements 121 of different specifications include filter elements 121 of different pleat densities and different sizes.
[0063] In this implementation, a partitioned purging nozzle group 16 can be set in the equipment. The partitioned purging nozzle group 16 can switch between different purging nozzle groups 161 according to the preliminary purging parameters to realize the purging and dust removal operation of different pleated areas of the filter element 121 of different specifications.
[0064] In this implementation, the dust filter elements 121 to be cleaned of different specifications include dust filter elements with different pleat densities and dust filter elements 121 of different sizes, and a suitable purging operation scheme is configured for these differentiated filter elements.
[0065] It should be noted that the partitioned purging nozzle group 16 can be composed of multiple independent nozzle units. Each nozzle unit corresponds to the pleated area of a filter element of a specific specification. The nozzle group can be quickly switched according to the command signal of the preliminary purging parameters to accurately purge the target pleated area of the filter element.
[0066] For example, the partitioned blowing nozzle group 16 uses multiple independently arranged nozzle units in a ring to blow dust away the pleated areas of the filter element 121 at different heights. When blowing dust away a large-sized filter element with high pleat density, the nozzle group can be switched to the corresponding large coverage area and adapted to the high pleat gap to thoroughly blow away each pleat area of the filter element. In this implementation, the partitioned blowing nozzle group 16 can be used to switch between different specifications of filter elements 121 for dust removal.
[0067] For example, the multiple sets of purge nozzles arranged independently in a ring in the partitioned purge nozzle group 16 can be controlled to open and close by multiple independent solenoid valves, and the multiple independent nozzle units of the partitioned purge nozzle group 16 can be independently controlled.
[0068] It should be noted that the multiple blowing nozzle groups of the partitioned blowing nozzle assembly have different blowing angles and blowing nozzle diameters, which can match the pleated structure characteristics of filter elements of different specifications to ensure that the blowing airflow can effectively reach each pleated area of the filter element.
[0069] For example, for filter cartridges with low pleat density, a nozzle group with a large diameter and wide blowing angle can be selected to improve the blowing coverage efficiency; for small-sized filter cartridges, a nozzle group with a small diameter and directional blowing angle can be selected to focus on the pleated area of the filter cartridge for precise blowing.
[0070] In some implementations, the pollution level classification component 13 is also used to determine the corresponding pollution level of the filter element 121 of different specifications based on the pressure difference and dust adhesion on both sides of the filter element 121 of different specifications, and to determine different preliminary purging parameters for filter elements 121 of the same specifications with the same pollution level. The preliminary purging parameters include purging pressure, purging flow rate, purging frequency, and the purging nozzle group corresponding to the zoned purging nozzle group.
[0071] In this implementation, the pollution level of each filter element can be determined by relying on the pollution level classification component 13 and combining the pressure difference and dust adhesion data on both sides of the filter elements of different specifications.
[0072] In this implementation, multiple sets of different preliminary purging parameters can be configured for the same specification of dust filter element 121 with the same pollution level, providing a variety of parameter options for subsequent purging and dust removal tests.
[0073] In this implementation, the initial purging parameters can be set to include purging pressure, purging flow rate, purging frequency, and the purging nozzle group corresponding to the zoned purging nozzle group. By adjusting these four types of parameter combinations, different purging intensities, frequencies, and purging areas can be controlled.
[0074] It should be noted that, with the help of a preset empirical value table, the pressure difference, dust adhesion, and pollution level of different specifications of dust filter elements 121 to be cleaned can be correlated, and multiple sets of differentiated preliminary purging parameters can be matched for the same specifications of dust filter elements 121 to be cleaned at the same pollution level.
[0075] For example, the empirical value table can indicate that when the pressure difference of a certain specification of filter element is in a specific range and the dust adhesion is in a specific range, it corresponds to a medium pollution level. The table also provides preliminary purging parameters for configuring three sets of purging nozzle groups with different purging pressures, flow rates, frequencies, and zone purging nozzle groups for the medium pollution filter element of that specification.
[0076] In some implementations, the gas purging assembly 14 is also used to control the zonal purging nozzle group to perform purging and dust removal tests on filter cartridges of the same specification and the same pollution level according to different preliminary purging parameters.
[0077] In this implementation, the gas purging assembly 14 can control the operation of the partitioned purging nozzle group 16, and in combination with different preliminary purging parameters, purging and dust removal tests can be carried out on the same specification of dust removal filter elements of the same pollution level.
[0078] In this implementation, the pressure difference and dust adhesion of the filter element before and after purging can be recorded simultaneously during the test, providing a complete data basis for subsequent parameter evaluation.
[0079] In some implementations, the purging control component is also used to determine the product of the pressure difference change and the dust adhesion change corresponding to the purging dust removal test, as the dust removal effect index. It is also used to determine the product of the purging pressure, purging flow rate, and purging frequency corresponding to the purging dust removal test, as the dust removal input index. Furthermore, it is used to determine the quotient of the dust removal effect index and the dust removal input index, as the cleanliness index corresponding to the purging dust removal test. It is also used to determine the maximum cleanliness index for purging dust removal tests on filter cartridges of the same specification and pollution level using different preliminary purging parameters, and to determine the purging nozzle group corresponding to the maximum cleanliness index as the optimal purging nozzle group and the preliminary purging parameters corresponding to the maximum cleanliness index as the optimal preliminary purging parameters. Filter cartridges of the same specification and pollution level are then purged according to the optimal purging nozzle group and the optimal preliminary purging parameters.
[0080] In this implementation, the purging control component 15 can calculate the product of the pressure difference change value and the dust adhesion change value corresponding to the purging dust removal test, and set this value as the dust removal effect index to quantify the dust removal effect of the purging operation.
[0081] In this implementation, the purging control component 15 can calculate the product of the purging pressure, purging flow rate and purging frequency corresponding to the purging dust removal test, and set this value as the dust removal input index to quantify the resource input level of the purging operation.
[0082] In this implementation, the dust removal effect index and the dust removal input index can be calculated by the purging control component 15, and this value can be set as the cleanliness index corresponding to the purging dust removal test, so as to comprehensively evaluate the efficiency and input balance of the purging parameters.
[0083] In this implementation, the cleaning index of the same specification dust filter cartridges of the same pollution level under different preliminary purging parameters can be compared by the purging control component 15, and the highest cleaning index can be selected.
[0084] In this implementation, the purging nozzle group corresponding to the maximum cleanliness index can be determined as the optimal purging nozzle group, and the preliminary purging parameters corresponding to the index can be determined as the optimal preliminary purging parameters, thus providing the optimal configuration scheme for the formal purging operation.
[0085] In this implementation method, for the same specification dust filter element 121 with different pollution levels, the optimal purging nozzle group and the optimal preliminary purging parameters determined under the corresponding pollution level can be used to carry out formal purging and dust removal operations.
[0086] Through this implementation, for filter cartridges with different pleat densities and sizes, the zoned purging nozzle group can switch nozzle groups according to the preliminary purging parameters to perform purging dust removal tests on different pleat areas of the filter cartridge. The pollution level classification component determines the pollution level by combining the pressure difference on both sides of the filter cartridge and the amount of dust adhesion, and matches different preliminary purging parameters to filter cartridges of the same specification with the same pollution level. The gas purging component works with the nozzle group to perform the test, and finally the purging control component determines the optimal configuration, which can accurately cover each pleat area of the filter cartridge, improve the comprehensiveness of purging, and avoid local dust residue.
[0087] Through this implementation, the pollution level classification component determines the pollution level for different specifications of filter cartridges to be cleaned by combining the pressure difference on both sides and the amount of dust adhering. Then, different preliminary purging parameters are formulated for filter cartridges of the same specifications and pollution level. The gas purging component works with the zoned purging nozzle group to carry out purging and dust removal tests. The purging control component calculates the dust removal effect index, dust removal input index, and cleanliness index. The optimal purging nozzle group and the optimal preliminary purging parameters corresponding to the maximum cleanliness index are selected to perform purging. This allows the purging configuration to better match the actual state of the filter cartridge, improves the dust removal efficiency of filter cartridges of the same specification and pollution level, and reduces ineffective energy consumption.
[0088] In some implementations, the dust adhesion monitoring component 12 is also used to detect the amount of dust residue deep in the folds of the filter element to be cleaned in the high temperature and high pressure dust collector online, and to detect the change in the amount of dust residue deep in the folds of the filter element to be cleaned before and after the gas purging component 14 performs the purging dust removal test.
[0089] In this implementation, the amount of dust residue deep in the folds of the filter element to be cleaned in the high-temperature and high-pressure dust collector can be obtained online through the dust adhesion monitoring component 12. At the same time, the change in the amount of dust residue deep in the folds of the filter element before and after the gas purging component 14 carries out the purging dust removal test can be obtained, providing multi-dimensional data support for the subsequent dust removal effect evaluation.
[0090] It should be noted that after the amount of dust adhesion changes tends to stabilize, the value obtained by subtracting the initial weight of the filter element from the total weight of the filter element and the dust is the amount of dust residue deep in the folds.
[0091] For example, when the amount of dust adhering to the filter element surface no longer changes, the total weight data of the filter element and dust at this time is collected, and the initial weight of the filter element recorded in advance is subtracted. The result is the amount of dust residue deep in the folds of the filter element.
[0092] In some implementations, the zoned purging nozzle group 16 also includes a purging angle adjustment component. This component switches the purging nozzle group and its purging angle according to preliminary purging parameters, allowing for purging and dust removal of different pleated areas of different specifications of filter elements at different purging angles. These different specifications of filter elements include those with different pleat densities, sizes, and pleat structures.
[0093] In this implementation, a blowing angle adjustment component can be set in the partitioned blowing nozzle group 16. This component can switch the blowing nozzle group and the corresponding blowing angle according to the preliminary blowing parameters. Multiple blowing nozzle groups correspond to different blowing wrinkle areas and blowing angles. The blowing angle adjustment component can switch the partitioned blowing nozzle group 16 through the solenoid valve to switch the blowing wrinkle area and blowing angle, thereby carrying out blowing dust removal operations on different wrinkle areas of filter cartridges of different specifications according to the matching blowing angle.
[0094] For example, such as Figure 4 As shown, the three annular blowing nozzle groups 161 in the partitioned blowing nozzle group 16 can be used to blow different pleated areas of filter cartridges of different specifications at different blowing angles.
[0095] Figure 5 This is a schematic diagram of the structure of the filter element pleats and the included angle of the blowing direction in the second type of dust collector filter element cleaning equipment provided in the embodiments of this application, as shown below. Figure 5 As shown, the blowing direction in the blowing nozzle assembly 161 and the extension direction of different pleated areas of the filter element form angles of α1, α2, and α3, respectively, so that the three annular blowing nozzle assemblies 161 can be used to blow different pleated areas of filter elements of different specifications at different blowing angles.
[0096] It should be noted that the different specifications of the dust removal filter cartridges cover filter cartridge types with different pleat densities, different external dimensions and different filter cartridge pleat structures, to adapt to different purging configuration requirements.
[0097] For example, filter elements with a tight pleated structure, large size, and high pleat density, and filter elements with a loose pleated structure, small size, and low pleat density, all belong to different specifications of dust removal filter elements.
[0098] In some implementations, the pollution level classification component 13 is also used to determine the corresponding pollution level of different specifications of filter elements to be cleaned based on the pressure difference and dust adhesion on both sides of the filter elements to be cleaned, and to determine different preliminary purging parameters for filter elements of the same specifications with the same pollution level. The preliminary purging parameters include purging pressure, purging flow rate, purging frequency, and purging angle, where the purging angle is the angle between the purging direction and the extension direction of the grooves in the filter element pleats.
[0099] In this implementation, the pollution level of each filter element can be determined by the pollution level classification component 13, combined with the pressure difference and dust adhesion on both sides of the filter elements of different specifications. At the same time, multiple sets of different preliminary purging parameters can be set for filter elements of the same specifications with the same pollution level, providing diverse configuration options for purging tests.
[0100] It should be noted that the preliminary purging parameters include purging pressure, purging flow rate, purging frequency, and purging angle, where the purging angle is defined as the angle between the purging direction and the extension direction of the grooves of the filter element pleats.
[0101] For example, when the grooves of the filter element pleats extend in a horizontal direction, the purging direction and the horizontal direction form a set angle, which is the corresponding purging angle parameter.
[0102] In some implementations, the gas purging assembly 14 is also used to control the zonal purging nozzle group to perform purging and dust removal tests on filter cartridges of the same specification and the same pollution level according to different preliminary purging parameters.
[0103] In this implementation, the gas purging assembly 14 can control the partitioned purging nozzle group. Based on the different preliminary purging parameters set, purging and dust removal tests are carried out one by one on the same specification dust filter elements with the same pollution level, and the corresponding data is collected for subsequent parameter optimization.
[0104] In some implementations, the purging control component 15 is also used to determine the product of the pressure difference change, dust adhesion change, and dust residue change in the folds corresponding to different purging angles in the purging dust removal test, as the dust removal effect index. It is also used to determine the product of the purging pressure, purging flow rate, and purging frequency corresponding to different purging angles in the purging dust removal test, as the dust removal input index. Furthermore, it is used to determine the quotient of the dust removal effect index and the dust removal input index at different purging angles, as the cleanliness index corresponding to the purging dust removal test at different purging angles. It is also used to determine the maximum cleanliness index for purging dust removal tests on filter cartridges of the same specification and pollution level under different preliminary purging parameters at different purging angles, and to determine the purging nozzle group corresponding to the maximum cleanliness index as the optimal purging nozzle group and the preliminary purging parameters corresponding to the maximum cleanliness index as the optimal preliminary purging parameters. Filter cartridges of the same specification and pollution level are purged according to the optimal purging nozzle group and the optimal preliminary purging parameters.
[0105] In this implementation, the dust removal effect index of the test can be obtained by multiplying the pressure difference change, dust adhesion change and dust residue change in the fold depths after the dust removal test at different blowing angles by the blowing control component 15.
[0106] It should be noted that when determining the dust removal effect index at different blowing angles, the change in pressure difference, the change in dust adhesion, and the change in dust residue deep in the folds obtained at that angle can be multiplied to quantify the dust removal effect in multiple dimensions.
[0107] For example, at a certain purging angle, corresponding data on the change in pressure difference, the change in dust adhesion, and the change in dust residue deep in the folds are collected. Multiplying the three values together yields the dust removal efficiency index at that purging angle.
[0108] In this implementation, the blowing control component 15 can multiply the blowing pressure, blowing flow rate and blowing frequency corresponding to the blowing dust removal test at different blowing angles, and the result can be used as the dust removal input index of the test.
[0109] In this implementation, the dust removal effect index at different blowing angles can be divided by the corresponding dust removal input index by the blowing control component 15, and the result is used as the cleanliness index corresponding to the test.
[0110] In this implementation, the cleaning index of the same specification dust filter element of the same pollution level under different cleaning angles and different preliminary cleaning parameters can be compared by the purging control component 15. The largest cleaning index is selected, and the purging nozzle group corresponding to the cleaning index is determined as the best purging nozzle group, and the corresponding preliminary cleaning parameters are determined as the best preliminary cleaning parameters.
[0111] In this implementation, the purging control component 15 can be used to carry out purging and dust removal operations for filter cartridges of the same specification with different pollution levels by using the best matching purging nozzle group and the best preliminary purging parameters.
[0112] Through this implementation, the blowing angle adjustment component of the partitioned blowing nozzle group switches the blowing nozzle group and blowing angle according to the preliminary blowing parameters, and blows different pleated areas of different specifications of filter cartridges to be dusted at the corresponding blowing angle. The blowing control component uses the product of the multi-dimensional changes as the dust removal effect index, and calculates the cleaning index in combination with the input index to determine the optimal parameters. It can accurately monitor the dust deep in the pleats, improve the thoroughness of dust removal, and avoid the accumulation of residues that affect the performance of the filter cartridge.
[0113] This implementation adds a purging angle to the preliminary purging parameters determined by the pollution level classification component. The purging angle is the angle between the purging direction and the extension direction of the grooves in the filter element pleats. The gas purging component controls the purging nozzle group in the control zone to conduct purging tests according to the preliminary purging parameters including the purging angle. The purging control component calculates the dust removal effect index and the input index based on multi-dimensional data. The optimal parameters are selected through the cleanliness index, expanding the dimensions of purging parameter optimization, taking into account both dust removal effect and input cost, making parameter selection more scientific, and reducing energy consumption while ensuring effectiveness. Purging after selecting the optimal parameters through the cleanliness index broadens the equipment's adaptability range, enabling precise purging of diverse filter elements and ensuring that all types of filter elements achieve ideal dust removal effects.
[0114] Figure 5 This is a schematic diagram of the control structure of the second type of dust collector filter cleaning equipment provided in the embodiments of this application, as shown below. Figure 5 As shown, in some implementations, a filter life monitoring component 17 is also included. The filter life monitoring component 17 is used to obtain the filter life of different specifications of filter elements to be dusted, and to determine the pressure difference change weight, dust adhesion change weight and dust residue change weight in the folds based on the filter life of different specifications of filter elements to be dusted.
[0115] In this implementation, a filter life monitoring component 17 can be added to the dust collector filter cleaning equipment. The filter life monitoring component 17 can obtain the cumulative usage time of filter elements of different specifications to be cleaned. Based on the actual usage time of filter elements of different specifications, the weights for pressure difference changes, dust adhesion changes, and dust residue changes in the folds can be determined respectively, providing a suitable weight basis for multi-dimensional evaluation of dust removal effect.
[0116] It should be noted that the filter life monitoring component 17 can rely on a preset empirical value table to divide the wear stages according to the usage time of different specifications of dust removal filter elements, and configure different weight ratios accordingly. Under different wear stages, the weight ratios of each item can be adjusted according to the degree of filter element aging.
[0117] For example, for filter cartridges of the same specification, when in the low-loss stage, the weight of pressure difference change can be set to the highest, the weight of dust adhesion change is medium, and the weight of dust residue change in the folds is low; when entering the high-loss stage, the weight of dust residue change in the folds is adjusted to the highest, and the weights of the other two items are reduced accordingly.
[0118] In some implementations, the purging control component 15 is also used to determine the sum of the product of the pressure difference change value and the pressure difference change weight, the product of the dust adhesion change amount and the dust adhesion change weight, and the product of the dust residue amount in the fold depth and the dust residue change weight in the fold depth corresponding to the purging dust removal test at different purging angles, as a dust removal effect index.
[0119] In this implementation, the purging control component 15 can perform weighted calculation operations on the purging dust removal test data under different purging angles. It can first calculate the product of the pressure difference change value and the corresponding pressure difference change weight, the product of the dust adhesion change amount and the corresponding dust adhesion change weight, and the product of the dust residue amount in the fold depth and the corresponding dust residue change weight in the fold depth. Then, it sums up these three product results to obtain the dust removal effect index under the purging angle.
[0120] It should be noted that when calculating the weighted sum of the dust removal efficiency index, it is necessary to first accurately obtain the monitoring data of each item under the corresponding blowing angle, then match the corresponding weight values determined by the filter life monitoring component, and calculate step by step according to the logic of multiplication and summation to ensure the accuracy of the result.
[0121] For example, at a specific purging angle, three data points are obtained: pressure difference change, dust adhesion change, and dust residue in the folds. At the same time, the corresponding weight values are matched, and the product of each data point and its weight is calculated in turn. Finally, the three product results are added together, and the resulting value is the dust removal effect index for that scenario.
[0122] Through this implementation, the filter life monitoring component obtains the usage time of filter elements of different specifications to be dusted. Based on this usage time, it determines the weights of pressure difference change, dust adhesion change, and dust residue change in the folds. The purging control component sums the products of pressure difference change and pressure difference change weight, dust adhesion change and dust adhesion change weight, and dust residue in the folds and dust residue change weight, and uses this sum as the dust removal effect index. The weights of each evaluation index are adjusted in combination with the actual wear and tear of the filter element to improve the accuracy of dust removal effect evaluation and make the purging effect judgment more consistent with the actual condition of the filter element.
[0123] In this implementation, the purging control component uses the quotient of the weighted dust removal efficiency index and the dust removal input index as the cleaning index to determine the optimal purging nozzle group and the optimal initial purging parameters. The weight of the dust removal efficiency index is adjusted according to the filter element's usage time, which can adapt to the dust removal needs of filter elements with different wear levels. This makes the match between purging input and dust removal effect more reasonable, reduces ineffective input while ensuring dust removal quality, and improves the economy and effectiveness of cleaning operations. It can take into account both the filter element's contamination status and usage wear, which can not only remove dust from filter elements with different wear levels but also avoid excessive purging that causes additional damage to aging filter elements. This helps to extend the overall service life of the filter elements and improve the scientific nature of filter element maintenance operations.
[0124] In some implementations, multiple dust removal and filtration channels are also included, each containing multiple identical filter cartridges for dust removal and filtration.
[0125] In this implementation, multiple independently operating dust removal and filtration channels can be configured. Each dust removal and filtration channel integrates multiple dust removal filter elements of the same specifications. These filter elements carry out dust removal and filtration operations simultaneously, ensuring the consistency of filtration effect within a single channel.
[0126] It should be noted that each dust removal and filtration channel is an independent filtration unit. The dust removal filter elements of the same specification inside can be arranged in an array, sharing the same air inlet and outlet branches, which facilitates unified monitoring and control.
[0127] For example, 12 filter cartridges with identical pleat density, size and pleat structure can be set in a dust removal and filtration channel, evenly distributed in the filtration chamber of the channel, to simultaneously complete the dust removal and filtration of the gas.
[0128] In some implementations, the purging control component 15 is also used to acquire the preliminary cleaning and purging parameters, actual channel cleanliness index, and preset channel cleanliness index corresponding to different dust removal filter channels in the purging dust removal test. The purging control component 15 is also used to determine the difference between the preset channel cleanliness index and the actual channel cleanliness index corresponding to different dust removal filter channels, and the ratio of the preset channel cleanliness index to this value, as the cleanliness index deviation ratio corresponding to different dust removal filter channels. The 1.5 power of the cleanliness index deviation ratio is then determined as the cleaning and purging parameter adjustment ratio.
[0129] In this implementation, three types of key data can be collected from each dust removal filter channel during the dust removal test phase through the purging control component, including the pre-configured preliminary cleaning and purging parameters, the actual channel cleanliness index achieved after the test, and the preset channel cleanliness index set based on the standard state of the filter element.
[0130] It should be noted that the preliminary cleaning and purging parameters are the initial purging configuration parameters matched with the corresponding filter element specifications, the actual channel cleanliness index is the comprehensive cleanliness quantification value after the filter element in the channel is purged, and the preset channel cleanliness index is the quantification value corresponding to the standard cleanliness state of the filter element of this specification.
[0131] For example, the preliminary cleaning and purging parameters may include a specific combination of purging pressure, flow rate and frequency, and the actual channel cleanliness index and the preset channel cleanliness index may adopt a quantitative score range of 0 to 100.
[0132] In some implementations, the purging control component 15 is also used to increase the purging pressure, purging flow rate, and purging frequency according to the adjustment ratio of the cleaning and purging parameters, thereby obtaining the adjusted cleaning and purging parameters corresponding to the dust removal filter channel. The purging control component 15 is also used to control the gas purging component to purge the filter element according to the adjusted cleaning and purging parameters.
[0133] In this implementation, the cleaning data of each dust removal and filtration channel can be quantified by the purging control component 15. The difference between the actual channel cleaning index and the preset channel cleaning index is divided by the preset channel cleaning index to obtain the cleaning index deviation ratio of the corresponding channel, thereby quantifying the degree of deviation between the channel cleaning effect and the standard value.
[0134] It should be noted that the calculation of the cleaning index deviation ratio is based on the preset channel cleaning index. A positive deviation means that the cleaning effect is better than the standard, and a negative deviation means that the cleaning effect does not meet the standard. Subsequent parameter adjustment operations are only performed when a negative deviation occurs.
[0135] For example, if the preset channel cleanliness index of a certain channel is 90 and the actual channel cleanliness index is 80, the difference between the two can be calculated as 10. Dividing this by the preset value of 90, the cleanliness index deviation ratio is approximately 0.11.
[0136] In this implementation, when the purging control component 15 increases the purging pressure, purging flow rate, and purging frequency according to the purging parameter adjustment ratio, the purging control component can multiply the purging pressure, purging flow rate, and purging frequency in the initial purging parameters by the corresponding 1 and the sum of the purging parameter adjustment ratio to obtain the purging adjustment parameters specific to the dust removal filter channel, ensuring that the parameter adjustment is accurately adapted to the cleaning deviation state of the channel.
[0137] It should be noted that the parameter adjustments only apply to three dimensions: purging pressure, purging flow rate, and purging frequency, and are scaled up proportionally to ensure that the power configuration for purging is adapted in sync, thus avoiding any imbalance in a single parameter that could affect the purging effect.
[0138] For example, if the initial cleaning and purging parameters are a purging pressure of 0.5 MPa, a purging flow rate of 100 m³ / h, and a purging frequency of 5 times / minute, and the cleaning and purging parameter adjustment ratio is 1.12, the adjusted purging pressure, flow rate, and frequency can be calculated respectively.
[0139] In this implementation, the purging control component can send the adjustment cleaning and purging parameters corresponding to each dust removal filter channel to the gas purging component. The gas purging component then performs purging operations on the filter element to be cleaned in the corresponding channel based on these parameters, ensuring that the purging configuration of each channel accurately matches its cleaning requirements.
[0140] In this implementation, each dust removal filtration channel contains multiple identical filter cartridges for dust removal. The purging control component acquires the preliminary cleaning and purging parameters, actual channel cleanliness index, and preset channel cleanliness index for different dust removal filtration channels during the purging dust removal test. It calculates the ratio of the difference between the actual channel cleanliness index and the preset channel cleanliness index to the preset channel cleanliness index as the cleanliness index deviation ratio. The corresponding power of this ratio is taken as the cleaning and purging parameter adjustment ratio. By increasing the purging pressure, purging flow rate, and purging frequency according to this ratio, the cleaning and purging parameters can be adjusted. This enables differentiated and precise purging for each channel, avoiding insufficient or excessive purging due to uniform parameter adaptation, and improving the stability of the overall dust removal effect of a single channel.
[0141] This approach optimizes the purging pressure, purging flow rate, and purging frequency by amplifying the adjustment range by power of the cleanliness index deviation ratio, rather than relying on fixed parameters for a single pollution level. It can quickly correct fluctuations in dust removal performance caused by differences in filter batches and usage environments between channels, continuously adapt to the real-time pollution status of the filter elements in the channel, and improve the dynamism and accuracy of parameter optimization.
[0142] This implementation method allows for independent calculation of the cleanliness index deviation ratio and the cleaning and purging parameter adjustment ratio for each dust removal and filtration channel containing filter elements of the same specification. It also allows for the development of dedicated adjustment parameters for each channel, enabling independent and precise control of each channel. This avoids parameter interference between different channels, fully utilizes the adaptability of the gas purging components, and reduces redundant consumption of overall dust removal investment while ensuring that dust removal in each channel meets standards, thereby improving the overall operating efficiency of the multi-channel system.
[0143] In some implementations, multiple filter element deformation monitoring components are also included, which are used to monitor the actual filter element deformation in the dust removal filtration channel.
[0144] In this implementation, multiple filter element deformation monitoring components can be set up. These components can monitor the actual filter element deformation in the dust removal and filtration channel in real time, providing data support for subsequent purging parameter safety verification.
[0145] It should be noted that the filter element deformation monitoring component can monitor the actual filter element deformation by using a resistance strain gauge installed on the filter element. The strain gauge changes its resistance value as the filter element deforms, and the corresponding deformation data is output after signal conversion, such as converting the deformation from resistance to deformation in millimeters.
[0146] For example, a resistance strain gauge can be installed at each of the easily deformable locations such as the top and bottom of the pleats of the filter element. The resistance strain gauge is woven into the filter element body, so that the resistance strain gauge can detect the deformation of the filter element and comprehensively capture the deformation of different areas of the filter element.
[0147] In some implementations, the purging control component 15 is also used to obtain the adjustment cleaning and purging parameters corresponding to different dust removal filter channels in the purging and dust removal test, the preset filter element deformation and the preset safety deviation index corresponding to the adjustment cleaning and purging parameters.
[0148] In this implementation, the purging control component 15 can obtain three types of key data corresponding to different dust removal and filtration channels during the purging and dust removal test phase: the adjusted cleaning and purging parameters, the preset filter element deformation corresponding to the parameters, and the preset safety deviation index.
[0149] For example, the adjustment cleaning and purging parameters of a certain dust removal filter channel may include specific purging pressure, flow rate and frequency, the corresponding preset filter element deformation may be set to a reasonable value, and the preset safety deviation index may be set to the corresponding standard threshold.
[0150] In some implementations, the purging control component 15 is also used to determine the difference between the actual filter element deformation and the preset filter element deformation, and the ratio of the preset filter element deformation, as the actual safety deviation index corresponding to the dust removal filtration channel. When the actual safety deviation index is greater than or equal to the preset safety deviation index, the purging control component 15 reduces the purging pressure of the cleaning and purging parameters according to the adjustment ratio of the cleaning and purging parameters, thus obtaining the deformation-controlled cleaning and purging parameters. The purging control component 15 is also used to control the gas purging component to purge the filter element according to the deformation-controlled cleaning and purging parameters.
[0151] In this implementation, the actual safety deviation index can be calculated by the purging control component 15. The calculation logic is to divide the difference between the actual filter element deformation and the preset filter element deformation by the preset filter element deformation, and the result is the actual safety deviation index corresponding to the dust removal and filtration channel.
[0152] It should be noted that this calculation method can quantify the degree of deviation of the actual deformation from the preset allowable value, and intuitively reflect the impact of the current purging parameters on the filter element structure.
[0153] For example, if the actual filter element deformation is a certain value and the preset filter element deformation is another corresponding value, the difference between the two can be divided by the preset filter element deformation to obtain the corresponding actual safety deviation index.
[0154] In this implementation, when the actual safety deviation index is greater than or equal to the preset safety deviation index, the purging control component 15 can adjust the purging pressure in the cleaning purging parameters. The purging pressure is reduced according to the adjustment ratio of the cleaning purging parameters, and the adjusted parameter combination is the deformation control cleaning purging parameters.
[0155] It should be noted that this adjustment logic is based on the safety of the filter element structure. By reducing the purging pressure, the force on the filter element is reduced, thus avoiding irreversible deformation of the filter element caused by excessive purging.
[0156] For example, if the adjustment ratio of the cleaning and purging parameters is a certain value, the purging pressure in the cleaning and purging parameters is adjusted to the corresponding value. The purging pressure is multiplied by (1 minus the adjustment ratio) to obtain the adjusted purging pressure. Combined with the original flow rate and frequency, the deformation control cleaning and purging parameters are formed.
[0157] In this implementation, the purging control component 15 can send instructions to the gas purging component to control the gas purging component to perform purging operations on the filter element in the corresponding dust removal and filtration channel according to the finally determined deformation control cleaning and purging parameters, thereby achieving dual protection of dust removal effect and filter element safety.
[0158] This implementation method monitors the actual filter element deformation in the dust removal filtration channel using a filter element deformation monitoring component. The purging control component obtains the preset filter element deformation and preset safety deviation index corresponding to the adjusted cleaning and purging parameters. The difference between the actual filter element deformation and the preset filter element deformation and the ratio of the preset filter element deformation are calculated as the actual safety deviation index. When the actual safety deviation index is greater than or equal to the preset safety deviation index, the purging pressure of the adjusted cleaning and purging parameters is reduced according to the adjustment ratio of the cleaning and purging parameters to obtain the deformation control cleaning and purging parameters. Then, the gas purging component is controlled to purge according to these parameters, effectively avoiding filter element deformation damage caused by excessive purging pressure, extending the service life of the filter element, and ensuring the structural integrity of the filter element.
[0159] This implementation dynamically lowers the purging pressure when the deformation exceeds the standard, generating deformation control cleaning purging parameters that balance dust removal efficiency and filter element safety. This achieves a dynamic balance between dust removal efficiency and filter element safety, ensuring that the dust removal effect meets the standard while avoiding safety hazards caused by over-purging and improving the accuracy of parameter adaptation. The adjusted parameters are only used when the actual safety deviation index meets the standard; otherwise, the purging pressure is corrected. This ensures that the purging operation of each dust removal filtration channel is carried out within the filter element safety threshold, improving the operational stability of the entire dust collector filter element cleaning equipment, reducing system downtime and maintenance due to filter element damage, lowering equipment operation and maintenance costs, and ensuring continuous and reliable dust removal operations.
[0160] In some implementations, the purging control component 15 is also used to obtain the deformation control channel cleaning index corresponding to the dust removal of the filter element in the dust removal and purging channel according to the deformation control cleaning and purging parameters.
[0161] In this implementation, the multi-dimensional monitoring data of the filter element in the dust removal and filtration channel after deformation control cleaning and blowing can be integrated through the purging control component 15 to calculate the corresponding deformation control channel cleanliness index, providing a precise quantitative basis for subsequent judgment on whether the filter element can still meet the usage requirements.
[0162] For example, after a dust removal filter channel completes a deformation control purging operation, the corresponding deformation control channel cleanliness index can be presented as a specific value that conforms to the system's preset quantitative standard, which can be used to intuitively reflect the cleanliness status of the filter element in that channel.
[0163] In some implementations, the purging control component is also used to determine the difference between the deformation control channel cleanliness index corresponding to different dust removal filter channels and the preset channel cleanliness index, and the ratio of the preset channel cleanliness index, as the cleanliness index deviation ratio corresponding to different dust removal filter channels. The purging control component is also used to issue a prompt message to replace the filter element in the dust removal filter channel when the cleanliness index deviation ratio is greater than or equal to the preset cleanliness index deviation ratio.
[0164] In this implementation, the preset channel cleaning index deformation and control channel cleaning index of each dust removal and filtration channel can be retrieved by the purging control component 15, and the ratio of the difference between the two to the preset channel cleaning index can be calculated. This ratio is defined as the cleaning index deviation ratio of the corresponding dust removal and filtration channel, thereby quantifying the degree of deviation between the filter element cleaning effect and the standard value.
[0165] For example, for a certain dust removal and filtration channel, the difference between its deformation control channel cleaning index and the preset channel cleaning index can be calculated first, and then the difference can be divided by the preset channel cleaning index. The final result is the cleaning index deviation ratio of the channel.
[0166] It should be noted that the preset cleaning index deviation ratio is a critical value pre-set by the dust removal system, used to determine whether the deviation of the filter element's cleaning effect has reached the point where it needs to be replaced.
[0167] For example, the preset cleaning index deviation ratio can be set as a fixed quantitative ratio based on the filtration efficiency requirements of the system operation, and used as a benchmark for filter replacement.
[0168] In this implementation, the cleaning index deviation ratio of each dust removal and filtration channel can be compared with the preset cleaning index deviation ratio by the purging control component. When the cleaning index deviation ratio is greater than or equal to the preset cleaning index deviation ratio, the corresponding information prompt module is triggered to issue a prompt message to replace the filter element in the dust removal and filtration channel, thereby ensuring the overall filtration efficiency of the dust removal system.
[0169] Through this implementation, the purging control component obtains the deformation control channel cleaning index corresponding to the dust removal of filter elements in the dust removal filtration channel according to the deformation control cleaning purging parameters. It determines the difference between the deformation control channel cleaning index corresponding to different dust removal filtration channels and the preset channel cleaning index, and the ratio of the preset channel cleaning index, as the cleaning index deviation ratio. When the cleaning index deviation ratio is greater than or equal to the preset cleaning index deviation ratio, a prompt message is issued to replace the filter elements in the dust removal filtration channel. It can accurately identify filter elements that still cannot meet the standards after purging, avoid incomplete cleaning caused by inefficient purging, and ensure the overall filtration efficiency of the dust removal system.
[0170] This implementation method allows the purging control component to determine whether the filter element still meets usage requirements after completing the deformation-controlled purging operation by calculating the cleanliness index deviation ratio. It only prompts for filter element replacement when the deviation ratio exceeds the standard, thus reasonably controlling the timing of filter element replacement, avoiding resource waste caused by premature replacement, preventing the use of expired filter elements from increasing equipment operating load, reducing the overall cost of filter element maintenance, and improving the economic efficiency of equipment operation. It effectively avoids problems such as abnormal system pressure and decreased filtration efficiency caused by insufficient filter element cleanliness, maintains the stability of dust removal system operating parameters, and reduces the number of equipment downtime maintenance caused by filter element failure.
[0171] In some implementations, the purging control component is also used to obtain the filter cartridge usage time, historical cleaning times, cumulative deformation, and optimal channel cleanliness index of the dust removal filtration channel when the cleanliness index deviation ratio is less than a preset cleanliness index deviation ratio. The cumulative deformation is the accumulated deformation value of the filter cartridge in the dust removal filtration channel during the historical cleaning process.
[0172] In this implementation, when the cleaning index deviation ratio is less than the preset cleaning index deviation ratio, the purging control component can acquire various operating data corresponding to the dust removal and filtration channel. These operating data include filter cartridge usage time, historical cleaning times, cumulative deformation, and optimal channel cleaning index. The cumulative deformation is the sum of the deformation generated by the filter cartridge in the dust removal and filtration channel during each cleaning process.
[0173] It should be noted that the filter element usage time is the cumulative working time since the filter element was put into operation, the historical cleaning number is the number of times the filter element has completed the blowing and dust removal operations, the cumulative deformation is the sum of the filter element deformation after each cleaning, and the optimal channel cleanliness index is the highest cleanliness index that the channel where the filter element is located has ever reached.
[0174] For example, the filter element of a certain dust removal filtration channel has a service life of 1800 hours, a historical cleaning count of 12 times, a cumulative deformation of 5.8 mm, and an optimal channel cleanliness index of 0.92.
[0175] In some implementations, the purging control component is also used to determine the predicted remaining lifespan of the filter cartridges in the dust removal filtration channel based on an empirical value table, considering factors such as cartridge usage time, historical cleaning frequency, cumulative deformation, and optimal channel cleanliness index.
[0176] In this implementation, the purge control component can call a preset experience value table and use the obtained filter cartridge usage time, historical cleaning times, cumulative deformation, and optimal channel cleanliness index as input parameters to determine the predicted remaining lifespan of the filter cartridge in the dust removal filtration channel.
[0177] It should be noted that the empirical value table is constructed based on statistical analysis of a large amount of actual operation, cleaning, deformation and cleaning performance data of filter elements of the same specification. Different parameter combinations correspond to different remaining life prediction ranges, which can provide accurate reference for judging the remaining life of filter elements.
[0178] For example, when the filter cartridge has been used for 1800 hours, has been cleaned 12 times, has a cumulative deformation of 5.8 mm, and has an optimal channel cleanliness index of 0.92, the remaining life of the filter cartridge can be predicted to be 600 hours using an empirical value table.
[0179] Through this implementation, when the cleaning index deviation ratio is less than the preset cleaning index deviation ratio, the purging control component obtains the filter cartridge usage time, historical cleaning times, cumulative deformation, and optimal channel cleaning index of the dust removal filtration channel. It determines the remaining life prediction value of the filter cartridge in the dust removal filtration channel through an empirical value table. Combining the actual use, cleaning, and deformation data of the filter cartridge, the life prediction is improved, which helps to plan filter cartridge replacement in advance and avoid sudden failures from affecting equipment operation.
[0180] This implementation method optimizes the overall operation and maintenance strategy of the equipment through a linkage mechanism, reduces unnecessary spare parts reserves or premature replacement operations, and effectively reduces equipment operation and maintenance costs. This measure can accurately predict filter replacement nodes, ensure that the dust removal and filtration channel always maintains good dust removal capacity, maintain the stable operation of the high temperature and high pressure dust collector, and avoid a sharp drop in dust removal efficiency due to the exhaustion of filter life.
[0181] In some implementations, a channel switching component is also included, which is used to switch the dust removal filter channel with a remaining life prediction value less than a preset remaining life prediction value to a dust removal filter channel with a remaining life prediction value greater than or equal to the preset remaining life prediction value in series.
[0182] In this implementation, a channel switching component can be set up. The channel switching component can identify the remaining life prediction value of each dust removal filter channel and adjust the dust removal filter channels with a remaining life prediction value less than the preset remaining life prediction value and the dust removal filter channels with a remaining life prediction value greater than or equal to the preset remaining life prediction value into a series state to optimize the overall filtration path of the airflow.
[0183] It should be noted that in the series configuration, the airflow passes sequentially through channels with lower remaining lifetime prediction values and channels with higher remaining lifetime prediction values, forming a gradient filtration layer. Channels with degraded performance undertake the initial coarse filtration task, while channels with good performance undertake the subsequent fine filtration task, making full use of the filtration capabilities of different channels.
[0184] For example, a high-temperature and high-pressure dust collector is configured with six dust removal and filtration channels, wherein the predicted remaining lifespan of channels 1, 2, and 3 is less than a preset value, and the predicted remaining lifespan of channels 4, 5, and 6 is greater than or equal to the preset value. The channel switching component can connect channels 1 and 4 in series, channels 2 and 5 in series, and channels 3 and 6 in series.
[0185] This implementation method obtains the predicted remaining lifespan of the filter element through components such as filter element life monitoring. The channel switching component switches the dust removal filter channel with a predicted remaining lifespan less than the preset value and the dust removal filter channel with a predicted remaining lifespan greater than or equal to the preset value to a series state. This allows the filter element with better performance to further filter the airflow after it has been treated by the filter element with reduced performance, thereby improving the overall dust removal accuracy and avoiding dust removal failure caused by insufficient performance of a single channel.
[0186] This implementation method connects dust removal filtration channels in different states based on the predicted remaining lifespan. It eliminates the need to immediately replace filter elements nearing the end of their lifespan, allowing them to continue utilizing their remaining filtration capacity. This maximizes the remaining value of the filter elements, reduces replacement frequency, and lowers the manpower and material resources required for spare parts procurement and maintenance. In the series connection state, degraded filter elements undertake preliminary coarse filtration, while high-performance filter elements undertake fine filtration, forming a gradient filtration hierarchy. This rationally allocates the filtration load of different filter elements, preventing excessive wear on high-performance elements, slowing down the overall filter element aging rate, and stabilizing the long-term energy consumption level of the equipment.
