Description

Technical Field

[0001] This invention relates to the field of environmental protection equipment technology, specifically to a three-row, five-chamber sintered plastic plate dust collector and its dust removal method. Background Technology

[0002] Dust collectors play a crucial role in environmental protection. By controlling the emission of dusty objects into the atmosphere, they can directly improve air quality and support the development of sustainable environmental protection operations. However, baghouse dust collectors have relatively limited initial filtration accuracy, and as the operating time increases, the accumulation of dust on the surface of the filter bags and the possible physical or chemical changes in the fiber structure can lead to a gradual decrease in filtration efficiency. It is difficult to maintain a stable ability to capture fine particles for a long time. Furthermore, in high humidity environments, especially when dealing with dusty gases containing steam (such as the high-humidity fumes generated during clay sand casting), moisture is easily condensed on the surface of the filter bags. When condensate combines with dust, it forms a highly adhesive, muddy layer that clogs the filter media pores, significantly increasing system resistance and reducing filtration performance. For dust layers that have already hardened due to condensation, conventional pulse-jet cleaning methods are ineffective. The blockage layer formed on the filter bag surface is often irreversible, preventing effective filter bag regeneration. In severe cases, system shutdown and replacement are necessary, impacting production continuity and increasing maintenance costs. Especially in low-temperature environments, where exhaust gas temperatures easily approach or fall below the dew point, condensation is further exacerbated, leading to accelerated filter bag blockage due to the mixing and deposition of moisture and dust in the flue gas, resulting in a significant decrease in system operational stability. Therefore, we propose a three-row, five-chamber sintered plate dust collector. Summary of the Invention

A dust removal frequency correction group is also provided on one side of the clean gas channel of the dust collector. The dust removal frequency correction group includes a time control unit, a dynamic execution unit, a differential pressure sensor, a PLC control unit, and a control signal reconstruction unit. The time control unit and the differential pressure sensor are both connected to the dynamic execution unit. The dynamic execution unit is connected to the PLC control unit. The PLC control unit is connected to the electromagnetic backflush pulse valve and the backflush air manifold. The control signal reconstruction unit is connected to the PLC control unit. The control signal reconstruction unit is used to update the dust removal interval in the next day's work cycle according to the signal interval collected by the differential pressure sensor.

[0004] Preferably, a sintered plate dust collector ash hopper is fixedly connected to the bottom of the main body of the sintered plate dust collector, and a dust-containing hood is fixedly connected to one end of the main body of the sintered plate dust collector. The dust-containing hood of the sintered plate dust collector is provided with a dust-containing gas inlet.

[0005] Preferably, the bottom of the sintered plastic plate filter element is provided with a fixing steel bar, the fixing steel bar is installed on the inner wall of the sintered plastic plate dust collector body, the bottom of the fixing steel bar is provided with a steel bar height adjustment support, the steel bar height adjustment support is fixedly connected to the sintered plastic plate dust collector body by bolts, and the output end of the steel bar height adjustment support is screwed to the fixing steel bar.

[0006] Preferably, a sintered plate filter element mounting plate is fixedly connected to the top of the sintered plate filter element, a sintered plate filter element sealing sponge pad is provided at the connection between the sintered plate filter element mounting plate and the sintered plate filter element, and the sintered plate filter element mounting plate has a filter element backflush port, the output end of the backflush pipe corresponds to the opening position of the filter element backflush port.

[0007] Preferably, a sealing rubber strip is provided between the main body of the sintered plate dust collector and the input end of the ash hopper of the sintered plate dust collector, and the sealing rubber strip is used to fill the connection gap of the input end of the ash hopper of the sintered plate dust collector.

[0008] Preferably, a U-shaped spiral discharge trough is fixedly connected to the bottom output end of the ash storage hopper of the sintered plate dust collector, and a gravity sealing valve is provided at the output end of the U-shaped spiral discharge trough. A sintered plate dust collector support leg is fixedly connected to the outside of the ash storage hopper of the sintered plate dust collector.

[0009] Preferably, a number of sintered plate dust collector support legs are fixedly connected to the inner side of the support legs, and a channel outlet is opened at one end of the clean gas channel of the dust collector.

[0010] Preferably, the clean gas passage of the dust collector is rotatably connected to a clean gas passage inspection door, and one end of the sintered plate dust collector body is hinged to a sintered plate dust collector inspection door.

[0011] The preferred dust removal method for a three-row, five-chamber sintered plastic plate dust collector includes the following steps: Step S1: Start the external dust removal fan. The system enters a negative pressure state. At this time, the dust-laden gas enters the main body of the sintered plate dust collector through the dust-laden gas inlet through the pipeline. When the gas passes through the sintered plate filter element, the dust is trapped on the surface of the filter element, while the clean gas enters the clean gas channel through the filter element back-blowing port and is discharged through the outlet. Step S2: When the pressure difference across the sintered plastic plate filter element exceeds the set value of the differential pressure sensor within the dust removal stage time or cycle set by the time control unit, the PLC control unit drives the electromagnetic back-blowing pulse valve to open, so that compressed air is injected vertically from the back-blowing air manifold through the back-blowing pipe into the back-blowing port of the filter element, so that the instantaneous airflow will knock off the dust on the surface of the sintered plastic plate filter element and fall into the dust collection hopper of the sintered plastic plate dust collector. Step S3: After the dust is removed, the PLC control unit controls the electromagnetic back-flushing pulse valve to close, restoring the normal filtration state. The dust in the ash hopper of the sintered plate dust collector is discharged through the U-shaped spiral discharge chute. Step S4: The cleaning time set by the original time control unit is used as the first cleaning interval. The cleaning operation period when the pressure difference across the plastic sintered plate filter element exceeds the set value of the differential pressure sensor in step S is entered into the control signal reconstruction unit, and this interval is used as the second cleaning interval. Step S5: Based on the daily input frequency of dusty gas, the interval length of the secondary cleaning interval is corrected by a weighted algorithm, and the interval length of the cleaning cycle in the next working cycle is updated by the control signal reassembly unit.

[0012] Compared to existing technologies, the advantages of this invention are as follows: Compared to traditional baghouse dust collectors, this solution increases the filtration area by integrating a rigid, wave-shaped sintered plastic plate filter element, while eliminating the need for a rigid frame in baghouse dust collectors and reducing the floor space. During use, under the action of an external dust collector fan, dust-laden gas enters the main body of the sintered plastic plate dust collector through the dust collection pipeline from the dust-laden gas inlet. After being filtered by the sintered plastic plate filter element, dust is adsorbed onto the surface of the filter element. At this time, clean gas is drawn into the clean gas channel of the dust collector through the filter element's back-blowing port, and then enters the external dust collector fan from the channel outlet. The dust adsorbed on the surface of the sintered plastic plate filter element is bounced into the dust collection hopper of the sintered plastic plate dust collector under the action of the back-blowing airflow and discharged through the U-shaped spiral discharge chute. Compared to baghouse dust collectors, the sintered plastic plate filter element and its back-blowing function can operate in humid environments without being easily clogged, and achieves filtration of dust-laden gas.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-7 As shown, the three-row, five-chamber sintered plate dust collector of the present invention includes a clean gas channel 1 for the dust collector, a sintered plate dust collector body 13 fixedly connected to the bottom of the clean gas channel 1, and an electromagnetic backflush pulse valve 4 and a backflush air manifold 5 installed at one end of the sintered plate dust collector body 13. The backflush air manifold 5 is fixedly connected to the main body 13 of the plastic sintered plate dust collector via the air manifold fixing bracket 7. The backflush air manifold 5 is fixedly connected to the output end of the electromagnetic backflush pulse valve 4. The other end of the backflush air manifold 5 is fixedly connected to the backflush pipe 41, and the output end of the backflush pipe 41 is set vertically downward. The bottom of the backflush air bag 5 is fixedly connected to the air bag drain ball valve 6, and several sintered plate filter elements 131 are provided inside the main body 13 of the sintered plate dust collector. A dust removal frequency correction group 20 is also installed on one side of the clean gas channel 1 of the dust collector. The dust removal frequency correction group 20 includes a time control unit, a dynamic execution unit, a differential pressure sensor, a PLC control unit, and a control signal reassembly unit. The time control unit and the differential pressure sensor are both connected to the dynamic execution unit. The dynamic execution unit is connected to the PLC control unit. The PLC control unit is connected to the electromagnetic backflush pulse valve 4 and the backflush air manifold 5. The control signal reassembly unit is connected to the PLC control unit. The control signal reassembly unit is used to update the dust removal interval in the next day's work cycle according to the signal interval collected by the differential pressure sensor.

[0024] The backflush air manifold 5 is fixedly connected to the main body 13 of the plastic plate dust collector via the air manifold fixing bracket 7. The backflush air manifold 5 is fixedly connected to the output end of the electromagnetic backflush pulse valve 4. The other end of the backflush air manifold 5 is fixedly connected to the backflush pipe 41, and the output end of the backflush pipe 41 is set vertically downward.

[0025] In one optional embodiment of this invention, the sintered plate filter element 131 has a rigid corrugated structure. The filter element backflush port 1331 has bolt slots on both sides for inserting bolts along the inner side lugs of the sintered plate dust collector body 13 to fix the filter element 131. The sintered plate filter element sealing sponge pad 132 provided on the filter element 131 is used to seal and isolate the sintered plate dust collector body 13 and the clean gas passage 1 of the dust collector. The lower end of the sintered plate filter element 131 is equipped with a stainless steel groove for fixing the core part of the sintered plate filter element 131, preventing damage during electromagnetic backflush pulse valve 4 opening. When the backflush pipe 41 performs pulse backflush, the sintered plate filter element 131 sways back and forth under the action of the backflush airflow. The sintered plate filter element 131 is arranged in a straight line and located directly below the backflush pipe 41. Each backflush port of the backflush pipe 41 needs to be vertically aligned with each backflush of the sintered plate filter element 131. To solve this problem, the fixing steel bar 134 is installed in the stainless steel groove at the lower end of the sintered plate filter element 131. The middle and both ends of the steel bar are provided with a steel bar height adjustment device (in this embodiment, a telescopic rod with a spring pin self-locking can be selected) to adjust the height of the fixing steel bar 134.

[0026] In one optional embodiment of this example, a backflush air manifold 5 is fixedly connected to a manifold discharge ball valve 6. A plurality of sintered plate filter elements 131 are provided on the inner side of the sintered plate dust collector body 13. A fixing steel bar 134 is provided at the bottom of the sintered plate filter element 131. The fixing steel bar 134 is installed on the inner wall of the sintered plate dust collector body 13. A steel bar height adjustment support 135 is provided at the bottom of the fixing steel bar 134. The steel bar height adjustment support 135 is fixedly connected to the sintered plate dust collector body 13 by bolts. The output end of the steel bar height adjustment support 135 is screwed to the fixing steel bar 134.

[0027] In this embodiment, air bag fixing brackets 7 are installed at the lower ends of both sides of the backflush air bag 5. The air bag fixing brackets 7 are used to prevent the air bag from flipping over under the reaction of the backflush airflow.

[0028] In one optional embodiment of this invention, a sintered plate dust collector ash hopper 9 is fixedly connected to the bottom of the sintered plate dust collector body 13, and a sintered plate dust collector dust hood 14 is fixedly connected to one end of the sintered plate dust collector body 13. The sintered plate dust collector dust hood 14 is provided with a dust-laden gas inlet 141.

[0029] In this embodiment, please refer to the appendix to the specification. Figure 1 The main body 13 of the sintered plastic plate dust collector is divided into five groups, and the number of the main bodies 13 of the sintered plastic plate dust collector can be increased or decreased according to the air volume required for dust removal.

[0030] In one optional embodiment of this example, a sintered plate filter element mounting plate 133 is fixedly connected to the top of the sintered plate filter element 131. A sintered plate filter element sealing sponge pad 132 is provided at the connection between the sintered plate filter element mounting plate 133 and the sintered plate filter element 131. The sintered plate filter element mounting plate 133 has a filter element backflush port 1331, and the output end of the backflush pipe 41 corresponds to the opening position of the filter element backflush port 1331.

[0031] In an optional embodiment of this invention, a sealing rubber strip 136 is provided between the main body 13 of the sintered plate dust collector and the input end of the ash hopper 9 of the sintered plate dust collector. The sealing rubber strip 136 is used to fill the connection gap at the input end of the ash hopper 9 of the sintered plate dust collector.

[0032] In one optional embodiment of this example, a U-shaped spiral discharge trough 10 is fixedly connected to the bottom output end of the ash storage hopper 9 of the sintered plate dust collector, and a gravity sealing valve is provided at the output end of the U-shaped spiral discharge trough 10. A sintered plate dust collector support leg 11 is fixedly connected to the outside of the ash storage hopper 9 of the sintered plate dust collector.

[0033] In use, under the action of the external dust collector fan, dust-laden gas enters the main body 13 of the sintered plate dust collector through the external dust collection pipeline from the dust-laden gas inlet 141. After being filtered by the sintered plate filter element 131, dust is adsorbed on the surface of the sintered plate filter element 131. Clean gas is then drawn into the clean gas channel 1 of the dust collector through the filter element back-blowing port 1331 of the sintered plate filter element 131, and then enters the external dust collector fan from the channel outlet 2. The dust adsorbed on the surface of the sintered plate filter element 131 is bounced off into the ash storage hopper 9 of the sintered plate dust collector under the action of the back-blowing airflow and then discharged through the U-shaped spiral discharge chute 10. Compared with bag dust collectors, the sintered plate filter element 131 and its back-blowing function can work in humid environments without being easily blocked, thus achieving the filtration of dust-laden gas.

[0034] In one optional embodiment of this invention, a plurality of sintered plate dust collector support legs 12 are fixedly connected to the inner side of the support legs 11.

[0035] In one optional embodiment of this invention, a channel outlet 2 is provided at one end of the clean gas channel 1 of the dust collector.

[0036] One end of the main body 13 of the sintered plate dust collector is hinged with a sintered plate dust collector inspection door 8; the sintered plate dust collector inspection door 8 is used to open and check the clogging status of the sintered plate filter element 131.

[0037] In this embodiment, the main body 13 of the sintered plate dust collector can be opened later through the inspection door 8, exposing the sintered plate filter element 131 to the outside. Then, the bolts connecting the sintered plate filter element 131 to the main body 13 can be removed. After that, the sintered plate filter element 131 can be pulled up to disengage the fixing steel bar 134 from the stainless steel groove at the lower end of the sintered plate filter element 131, and then the sintered plate filter element 131 can be directly removed. The main body 13 of the sintered plate dust collector has several fixing lugs of different heights on its inner side. After the height of the fixing steel bar 134 is adjusted by the steel bar height adjustment bracket 135, the sintered plate filter element 131 is fixed to the inner side of the main body 13 of the sintered plate dust collector.

[0038] Furthermore, to ensure the stability of subsequent dust removal, if the pressure difference across the sintered plate filter element 131 exceeds the set value of the differential pressure sensor before the dust removal time period set by the time control unit is reached, the PLC control unit can still drive the electromagnetic back-flushing pulse valve 4 to open. This allows compressed air to be vertically injected from the back-flushing air manifold 5 through the back-flushing pipe 41 into the filter element back-flushing port 1331. This instantaneous airflow causes the dust on the surface of the sintered plate filter element 131 to be ejected and fall into the dust collection hopper 9 of the sintered plate dust collector. The dust removal is triggered even before the time set by the time control unit is reached. During operation, the interval period triggered by the pressure difference is recorded in the control signal reconstruction unit. This interval is used as the secondary cleaning interval. Since the amount of cleaning is different in the morning and evening, the proportion value can be set according to the planned cleaning amount for the day, and the secondary cleaning interval can be further increased according to its proportion. For example, if more cleaning is required between 8 and 10 am, the secondary cleaning interval can be further reduced according to the number of cleanings. That is, the number of cleanings between 8 and 10 am accounts for 40% of the number of cleanings for the day. The secondary cleaning interval time is multiplied by 40% and used as the secondary cleaning interval, which is then reset by the time control unit.

[0039] The working steps of this invention are as follows: Step S1: Start the external dust removal fan and the system enters a negative pressure state. At this time, the dust-laden gas enters the main body 13 of the sintered plate dust collector through the dust-laden gas inlet 141 through the pipeline. When the gas passes through the sintered plate filter element 131, the dust is trapped on the surface of the filter element, while the clean gas enters the clean gas channel 1 through the filter element back-blowing port 1331 and is discharged through the outlet 2. Step S2: When the pressure difference across the sintered plate filter element 131 exceeds the set value of the differential pressure sensor within the dust removal stage time or cycle set by the time control unit, the PLC control unit drives the electromagnetic back-blowing pulse valve 4 to open, so that compressed air is injected vertically from the back-blowing air manifold 5 through the back-blowing pipe 41 into the filter element back-blowing port 1331, so that the instantaneous airflow will knock off the dust on the surface of the sintered plate filter element 131 and fall into the ash storage hopper 9 of the sintered plate dust collector. Step S3: After the dust is removed, the PLC control unit controls the electromagnetic back-flushing pulse valve 4 to close, restoring the normal filtration state. The dust in the ash storage hopper 9 of the plastic plate dust collector is discharged through the U-shaped spiral discharge chute 10. Step S4: The cleaning time set by the original time control unit is used as the first cleaning interval. The cleaning operation period when the pressure difference before and after the plastic plate filter element 131 exceeds the set value of the pressure difference sensor in step S2 is recorded into the control signal reconstruction unit, and this interval is used as the second cleaning interval.

[0040] Step S5: Based on the daily input frequency of dusty gas, the interval length of the secondary cleaning interval is corrected by a weighted algorithm, and the interval length of the cleaning cycle in the next working cycle is updated by the control signal reassembly unit.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.

Step S5: Based on the daily input frequency of dusty gas, the interval length of the secondary cleaning interval is corrected by a weighted algorithm, and the interval length of the cleaning cycle in the next working cycle is updated by the control signal reassembly unit.
