Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth bag dust collector, more particularly, it relates to an energy-saving pulse cloth bag dust collector. BACKGROUND

[0002] The existing cloth bag dust collector is widely used in metallurgy, building materials, electric power, chemical industry and other industries, and its basic structure mainly consists of a box body, filter bags, a pulse dust cleaning system and a dust hopper. Its working principle is: the dust-containing gas enters the filter chamber through the gas inlet, the dust is intercepted by the surface of the filter bag, and the purified gas enters the clean gas chamber and is finally discharged. With the extension of the running time, the surface of the filter bag is gradually covered with dust, which causes the pressure difference of the equipment to increase. In order to maintain the filtering efficiency and stable operation state of the dust collector, the traditional cloth bag dust collector generally uses pulse backflushing to clean the filter bag.

[0003] However, the existing cloth bag dust collector has the following disadvantages: first, most of the equipment uses the whole machine to clean the dust at the same time, that is, multiple filter bags are backflushed at the same time. This method not only causes the gas flow to fluctuate sharply, reduces the purification effect, but also causes the gas source energy consumption to increase significantly, and the operation cost is high. Secondly, the structure of the existing cloth bag sleeve is mostly straight rod or ring-shaped support, when the filter bag shakes under the alternating action of the gas flow and the backflushing gas flow, the filter bag often directly contacts and rubs with the hard support parts of the sleeve, which is easy to cause scratches and damage. This not only shortens the service life of the filter bag, but also increases the workload of replacing the filter bag and maintenance, and affects the long-term stable operation of the dust removal system.

[0004] Therefore, based on the above problems, the present application provides an energy-saving pulse cloth bag dust collector. SUMMARY

[0016] The execution module receives the information of the calculation module, performs spraying and blowing in sequence according to the calculation result, the spraying and blowing unit is a whole row of cloth bags, and the dust cleaning cannot be independently performed on a single cloth bag; the rows of filter bags are sequentially cleaned by alternating pulse, so that air flow fluctuation caused by simultaneous dust cleaning is avoided.

[0017] The interlocking protection module receives the temperature signal and the ash hopper level signal from the temperature sensor, triggers heating or adjustment measures to prevent bag sticking caused by condensation when the monitored temperature is lower than the dew point 25-30 DEG C, and triggers continuous ash unloading when the ash hopper level is higher than the set value to avoid dust accumulation causing back blowing failure.

DETAILED DESCRIPTION

[0043] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0045] Please refer to Figures 1-7 The present application provides the following technical solutions:

[0046] Embodiment one, please refer to Figures 1-7 , specifically refers to an energy-saving pulse bag dust collector, comprising a support frame 1, the top of the support frame 1 is fixedly connected with a filter chamber 2, the filter chamber 2 is set as a square box body, the filter chamber 2 comprises a partition plate 21, the partition plate 21 is fixedly connected to the top of the support frame 1, a temperature sensor is installed on the partition plate 21 for monitoring the temperature inside the dust collector, a through hole is formed at one end of the filter chamber 2, an air inlet 3 is connected at the through hole, the air inlet 3 is used for introducing dust-containing gas, a pulse blowback module 6 is connected at one end of the filter chamber 2, the pulse blowback module 6 comprises a plurality of groups of control valves 62, a clean gas chamber 4 is arranged at the top of the filter chamber 2, an air outlet 5 is formed at the end of the clean gas chamber 4 away from the air inlet 3, the air outlet 5 is horizontally formed, and an ash discharge hopper 7 is arranged at the bottom of the filter chamber 2.

[0047] The pulse blowback module 6 is built-in pulse system, which is used for controlling the frequency, sequence and ash cleaning area of pulse blowback, so as to realize energy-saving operation.

[0048] The separation plate 21 is uniformly provided with a plurality of groups of through holes 22, and each group of through holes 22 is fixed with a cloth bag sleeve 23 through bolts. The cloth bag sleeve 23 is internally integrated with a pressure sensor for monitoring the operating pressure difference of the cloth bag filtering area in real time. The cloth bag sleeve 23 comprises a circular ring 231 which is connected to the back of the separation plate 21 through bolts. The lower end of the circular ring 231 is longitudinally provided with a plurality of groups of support rings 233, and the support rings 233 are connected with a plurality of groups of support rods 232 which are equidistantly arranged between each support rod 232 to maintain the stable support of the cloth bag and prevent the cloth bag from shaking and deforming due to air flow pulses. At the bottom of the cloth bag sleeve 23, a plurality of groups of arc-shaped pipes 234 are arranged, which are fixedly connected to the support rods 232. The plurality of groups of arc-shaped pipes 234 form a hemisphere, and the arc-shaped pipes 234 are slightly convex to the support rods 232. By arranging the arc-shaped pipes 234, the support rods 232 can be prevented from tearing the cloth bag when the cloth bag is sleeved outside the cloth bag sleeve 23. At the same time, the cloth bag will also rub against the cloth bag sleeve 23 due to the shaking of the cloth bag caused by the surging of the air flow inside the dust collector.

[0049] In addition, the design of the arc-shaped pipes 234 increases the contact area between the cloth bag and the cloth bag sleeve 23, thereby preventing the cloth bag from being damaged due to small-area contact friction.

[0050] The pulse blowback module 6 comprises a horizontally arranged cylinder body 61 which adopts a cylindrical structure and is connected with a connecting port 65 at one end. The connecting port 65 is used for connecting with an external air source, and a plurality of groups of independently controllable control valves 62 are installed at the top of the cylinder body 61. Each group of control valves 62 is connected with a group of blow pipes 63 through pipelines, and a plurality of groups of blow heads 64 are equidistantly arranged along the length direction of the blow pipes 63. Each blow head 64 corresponds to one cloth bag sleeve 23, so as to ensure that the blowback air flow can accurately act on the inside of the filter bag and realize efficient dust removal.

[0051] The top of the filtering chamber 2 is provided with a clean gas chamber 4 which is provided with an air outlet 5 away from the air inlet 3. The air outlet 5 is horizontally arranged and used for discharging the purified gas filtered by the cloth bag. The bottom of the filtering chamber 2 is provided with a dust discharge hopper 7 which adopts an inverted bucket type structure and is internally provided with a pressure sensor for monitoring the height or weight of the dust accumulated in the hopper. When the dust in the hopper reaches a set value, the pulse system controls the dust outlet 72 at the bottom to be automatically opened through a switch valve 73, so as to realize timely dust removal and prevent the hopper from being blocked or the dust from being accumulated too much to affect the blowback effect.

[0052] The pulse system comprises a receiving module, a calculation module, an execution module and an interlocking protection module.

[0053] The receiving module is used for receiving the pressure value P transmitted by the cloth bag sleeve 23 pressure sensor. It needs to be explained that since several groups of cloth bag sleeves 23 transmit to the receiving module at the same time, in order to ensure the back blowing efficiency, the highest value of all the obtained pressure values P is used, and the preset threshold value is compared and calculated;

[0054] The computing module is used for calculating the ash removal frequency. Through the alternating pulse control and the differential pressure trigger logic, the pressure difference of the cloth bag dust collector is ensured to be maintained in the set range.

[0055] The executing module receives the information of the computing module, and according to the calculation result, the jetting and blowing are sequentially executed in turn. The jetting and blowing unit is a whole row of cloth bags, and cannot be independently cleaned for a single cloth bag. The cloth bags in each row are sequentially cleaned in an alternating pulse mode, so as to avoid the airflow fluctuation caused by simultaneous cleaning.

[0056] The interlocking protection module receives the temperature signal and the ash hopper level signal from the temperature sensor. When the monitored temperature is lower than the dew point safety margin, the air inlet is stopped to prevent dewing and bag blurring. When the ash hopper level is higher than the set value, the continuous ash removal is triggered to avoid the accumulated ash causing the back blowing failure.

[0057] The interlocking protection module receives the real-time temperature signal from the temperature sensor, and compares it with the preset dew point temperature and safety margin. When the monitored running temperature is lower than the dew point safety margin, the system immediately enters the dewing prevention logic. Preferably, in the embodiment, the safety margin is set to 25-30℃. When the detected temperature is ≤dew point+ safety margin, the interlocking protection module triggers the following actions: first, the air inlet fan is automatically turned off to avoid continuously sucking in low-temperature dust-containing gas and prevent the internal temperature of the system from further decreasing; second, the pulse jetting and blowing action is suspended to avoid the back blowing airflow under low-temperature conditions causing rapid cooling of the gas and condensation of water vapor, thereby effectively inhibiting the phenomenon of filter bag dewing and bag blurring.

[0058] Further, when the temperature rises to above the dew point+ safety margin, the interlocking protection module automatically releases the dewing prevention logic and restores the normal air inlet and pulse ash removal operation. Through the above interlocking control, the stability of the internal environment temperature of the cloth bag dust collector can be maintained under complex working conditions such as low temperature or high humidity, the filter bag blockage, shortened service life and decreased ash removal efficiency caused by dewing are avoided, and the operation reliability and safety of the equipment are significantly improved.

[0059] The receiving module is provided with a preset upper threshold value and a lower limit value Both of these factors together define the differential pressure range under normal operating conditions. It should be noted that operators can flexibly set the differential pressure threshold range according to different dust characteristics (such as sticky dust, fine particulate dust, fibrous dust, etc.) and the ventilation resistance characteristics of the filter bag material, and adjust the dust removal strategy in combination with actual working conditions to ensure a balance between dust removal effect and energy consumption.

[0060] If the current received pressure value P ≥ If the dust layer is not removed, the system will trigger the dust removal logic and automatically open the pulse valve to perform timed or zoned pulse cleaning operations, so that the dust layer attached to the surface of the filter bag is effectively peeled off and falls into the dust hopper, thereby restoring the air permeability of the filter bag.

[0061] If the current received pressure value P≤ If the dust removal logic is interrupted, it will be stopped to avoid excessive dust removal and increased energy consumption.

[0062] Furthermore, when P≥ is detected If the filter bag is severely clogged or the dust content in the inlet air increases sharply, the system will immediately trigger the forced cleaning mode. The forced cleaning mode uses a full-exhaust rapid pulse jet method, which means that all pulse valves are opened simultaneously or continuously to achieve rapid recovery of the filter bag with the maximum airflow impact force, thereby avoiding the continuous increase in system resistance that could lead to fan overload or forced shutdown of the entire unit.

[0063] The calculation module calculates the alternating pulse frequency F required for dust removal using the following formula, based on the differential pressure information provided by the receiving module:

[0064]

[0065] Where F is the alternating pulse frequency (routines / minute).

[0066] For a safety margin, a value of 1.05-1.30 is used;

[0067] The rate of increase of the pressure differential;

[0068] The average pressure drop (Pa / row·time) caused by each row of injection.

[0069] The calculation module calculates based on the total number of rows. Further calculations were performed on the pulse interval time for each row and the dust removal cycle:

[0070]

[0071] in, The interval between purges is s / row. This is one cleaning cycle (min) for the entire machine.

[0072] Specifically, a method for using the energy-saving pulse cloth bag dust collector is as follows:

[0073] S1: The dust-containing gas enters the filter chamber 2 from the gas inlet 3, and when passing through the cloth bag filter unit, the dust is intercepted by the cloth bag and settles in the ash bucket, and the purified gas enters the clean gas chamber 4 and is discharged from the system through the gas outlet 5, thereby realizing efficient purification of the inlet gas. In this process, the cloth bag resistance gradually increases, and the pressure difference rises over time, providing a control basis for subsequent ash removal.

[0074] S2: Data acquisition stage; the pressure difference data P is acquired in real time by the pressure sensor in the separation plate 21 and the cloth bag sleeve 23, the gas temperature is monitored by the temperature sensor, and the material level is monitored by the ash bucket pressure sensor.

[0075] S3: The received pressure difference P is compared with the preset upper threshold value and the lower threshold value

[0076] If P≥ , it indicates that the dust on the surface of the filter bag is thick, the system triggers the ash removal logic, and is ready to perform the blowing operation;

[0077] If P≤ , it indicates that the filter bag resistance is at a low level, and the ash removal logic is stopped to avoid unnecessary energy consumption and filter bag wear.

[0078] S4: Ash removal frequency calculation stage: the calculation module calculates the required pulse frequency F and the blowing interval according to the pressure difference rising rate r↑ and the blowing pressure drop △Pdrop,row.

[0079] S5: The execution module drives the electromagnetic valve 62 in turn according to the calculation result, so that the blowing pipe 63 and the blowing head 64 alternately blow the cloth bag. Each row of cloth bags is taken as a blowing unit, and no independent operation is performed on a single cloth bag. The alternate blowing mode can avoid air flow fluctuations caused by simultaneous blowing of multiple rows, thereby ensuring stable air flow in the system and uniform ash removal.

[0080] S6: The interlock protection module performs safety control according to the data of the temperature sensor and the ash bucket pressure sensor:

[0081] When the monitored temperature is lower than the preset dew point plus a safety margin, the system triggers the anti-condensation logic, including automatically closing the inlet fan and suspending the pulse blowing, to prevent the filter bag from being condensed and damaged;

[0082] When the ash bucket material level is higher than the set value, the system triggers the continuous ash removal operation to avoid excessive ash accumulation in the ash bucket, which may cause blowback failure or dust backflow.

[0083] ​S7: When the pressure difference P≥△P_emergency, the system determines that there is a serious blockage or sudden increase in dust content in the intake air, etc. extreme situation, immediately trigger the emergency dust cleaning mode. In the emergency mode, all the filter bags are blown at the same time or continuously, realizing the maximum airflow impact force to quickly clean the dust until the pressure difference returns to the safe range, ensuring the stable operation of the equipment under abnormal working conditions.
