Description

Technical Field

[0001] This invention relates to the field of baghouse dust collection technology, specifically to a baghouse dust collection system. Background Technology

[0002] A baghouse dust collector is a device that separates dust from flue gas. Also known as a filter dust collector, it is a dry, high-efficiency dust collector that uses bag-type filter elements made of woven fiber fabric to capture solid particles in dust-laden gas. Its working principle is that dust particles are intercepted by colliding with the filter fibers due to inertial forces as they wrap around the fibers.

[0003] In pulse jet and box-type pulse jet dust collectors, dust adheres to the outer surface of the filter bags. When dust-laden gas passes through the dust collector, the dust is captured on the outer surface of the filter bags, while clean gas passes through the filter media and enters the interior of the filter bags. The cages inside the filter bags support them, preventing them from collapsing, and also facilitate the removal and redistribution of the dust cake.

[0004] The fabric and design of dust collector bags should strive for high-efficiency filtration, easy dust removal, and durability. The selection of dust collector bags is crucial, as it directly affects the dust collector's performance. The selection of dust collector bags should consider the following factors: gas temperature, humidity, chemical properties, particle size, dust concentration, filtration velocity, and cleaning method.

[0005] In existing baghouse dust collectors, dust accumulates on the outer surface of the filter bags during operation. When the dust accumulates to a certain level, it causes blockage. When the filter bags are blocked, they create resistance to the airflow inside the equipment, thus reducing the overall air pressure. Since the air inlet of this equipment is often connected to devices such as cyclones that perform preliminary dust removal, and the airflow required by the upstream equipment is provided by the exhaust fan of this equipment, excessively low air pressure can damage the cyclone separator or other equipment upstream of this system. Furthermore, when the filter bags are blocked, operators must remove each bag individually, clean them manually, and allow them to air dry. The dust on the surface of the bags may not be severely blocked and does not require special cleaning by operators. However, cleaning requires stopping the operation of the entire system, which is time-consuming and labor-intensive, resulting in low cleaning efficiency. Therefore, it is necessary to design a baghouse dust collection system that reduces damage to upstream equipment and improves cleaning efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a bag filter dust collection system to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bag filter dust collection system, comprising a fixing mechanism, a dust collection mechanism, a collection mechanism, and a data module. The fixing mechanism is used to fix the filter bag to be dusted and drive the filter bag to be dusted to move. The dust collection mechanism is located at the bottom of the fixing mechanism and is used to remove dust from the filter bag fixed by the fixing mechanism. The collection mechanism is located at the bottom of the fixing mechanism and is used to collect the dust cleaned up by the dust collection mechanism. The data module is used to drive the fixing mechanism, the dust collection mechanism, and the collection mechanism to work and remove dust from the filter bag.

The top of each sliding connecting rod is made of magnetic material. When the system is in use, the dust collector can provide a sealed environment for dust removal from the gas. The sealing assembly is a contact seal, either a Z-type seal or a V-type seal, or a labyrinth seal + oil groove seal + oil slinger ring or a triple combination of labyrinth seal + oil groove seal + oil slinger ring for non-contact sealing. The limiting block is used to prevent the bag holder from falling to the bottom of the support plate. The electromagnet is used to provide attraction to the sliding connecting rod, driving the sliding connecting rod to move inside the fixed column.

[0009] According to the above technical solution, the dust removal mechanism includes an air inlet pipe, the end of which is connected to a pipe on one side of the dust collector. A suction pipe is connected to a pipe on one side of the top cover. An induced draft fan is installed at the end of the suction pipe. A booster pump is installed on the outside of the top cover. The output pipe of the booster pump is connected to several sets of air delivery pipes. The several sets of air delivery pipes are all located at the top of the bag frame. Several sets of air delivery holes are provided at the bottom of the several sets of air delivery pipes. A wind pressure detection sensor is installed inside the induced draft fan. When the system is in use, the air delivery holes correspond to the top of each set of placement slots. The air delivery holes are used to increase the wind pressure output by the booster pump and push the high-pressure air into the interior of the bag through the fixed column.

[0010] According to the above technical solution, the collection mechanism includes a collection chamber, a filter connected to the bottom pipe of the collection chamber, an infusion pipe connected to the outer pipe of the filter, a transfer pump installed at the end of the infusion pipe, and a collection bucket installed at the bottom of the filter. When the system is in use, the collection chamber is used to collect the blown-off dust, the transfer pump is used to deliver a cleaning solution into the collection chamber through the infusion pipe, and simultaneously discharge the cleaning solution inside the collection chamber outward through the infusion pipe. The filter is used to filter the mixed solution during this process, filtering the solids in the mixed solution into the collection bucket.

[0011] According to the above technical solution, an output cylinder is provided on the outside of the support frame, and an output connecting rod is driven to the output end of the output cylinder. A rotary motor is installed at the end of the output connecting rod, and a rotating connecting rod is driven to the output end of the rotary motor. The outer surface of the rotating connecting rod is connected to the top bearing of the top cover, and the bottom of the rotating connecting rod is fixed to the top of the bag frame.

[0012] According to the above technical solution, the data module includes a detection unit, a judgment unit, and a control unit. The detection unit is located inside the wind pressure detection sensor and is used to detect the wind pressure during the operation of the induced draft fan. The judgment unit is electrically connected to the detection unit and is used to receive the data information detected by the detection unit and to judge the received data information. The control unit is electrically connected to the judgment unit, the electromagnet, the induced draft fan, the booster pump, the transfer pump, the output cylinder, and the rotary motor. It is used to receive the judgment result of the judgment unit and control the electromagnet, the induced draft fan, the booster pump, the transfer pump, the output cylinder, and the rotary motor through the received data information to perform dust removal on the filter bag.

[0013] According to the above technical solution, the working steps of the bag filter dust collection system are as follows:

[0014] Step A: Open several sets of cover plates, place the dust bags to be removed into several sets of placement slots, and place several sets of fixing posts into the inside of the dust bags to fix them in place;

[0015] Step B: The control unit drives the induced draft fan to work at the rated output power, drawing the airflow from the inside of the inlet pipe into the inside of the dust collector, and drawing the airflow out from the exhaust pipe. During the gas movement, the dust in the gas is separated by the filter bag, and the dust adsorbed on the outer surface of the filter bag is removed by the gas.

[0016] Step C: The control unit drives the rotary motor to work, which drives the rotary linkage to rotate, and then drives the bag frame to rotate, rotating several sets of bags to the air outlet of the air inlet pipe, using the high-speed airflow at the air inlet pipe to remove dust from the outer surface of the bags.

[0017] Step D: During the dust removal process of the filter bags, the control unit drives the booster pump to operate intermittently, and discharges high-speed airflow through several sets of air outlets at the bottom of the air supply pipe to remove dust from several sets of filter bags placed inside the filter bag frame. Specifically, the high-speed airflow enters the interior of the filter bags and moves outward, pushing the dust adsorbed on the surface of the filter bags outward in the process.

[0018] Step E: During the dust removal process of the filter bag, the detection unit continuously monitors the air pressure during the operation of the induced draft fan and transmits the detected data to the judgment unit. Specifically, the real-time air pressure of the induced draft fan is recorded as follows: The wind pressure when the induced draft fan is running at its rated output power and the surface of the filter bag is free of dust is recorded as follows: ;

[0019] Step F: The judgment unit judges the received data information and transmits the judgment result to the control unit;

[0020] Step G: The control unit controls the electromagnet, booster pump, transfer pump and output cylinder according to the received data information to clean the cloth bag;

[0021] Step H: The dust blown off by the airflow falls into the inside of the collection chamber and then passes through the filter into the inside of the collection bucket, where the user collects the dust.

[0022] According to the above technical solution, the specific judgment process in step F is as follows:

[0023] when ≥0.8 At this point, the degree of blockage in the filter bag has no impact on the overall operation of the device, and it is determined that there is no need to clean the filter bag;

[0024] when At this point, the degree of clogging of the filter bag has a general impact on the overall operation of the device, and it is determined that basic dust removal of the filter bag is necessary.

[0025] when At this point, the degree of clogging of the filter bags has a significant impact on the overall operation of the device, and it is determined that deep dust removal of the filter bags is necessary.

[0026] According to the above technical solution, the basic dust removal process of the bag filter is as follows:

[0027] Step Fa1: The control unit drives the electromagnet to work, pulling the sliding link upward along the inside of the fixed column, so that the sliding link does not limit the bottom of the bag;

[0028] Step Fa2: The control unit drives the booster pump to work continuously, and inputs high-pressure gas into the interior of each group of filter bags through the air outlets of several sets of air supply pipes, so that the bottom of the filter bags is opened by the high-pressure gas, and the dust on the outside of the filter bags is pushed away by the impact force of the high-pressure gas flowing out from the inside of the filter bags.

[0029] Step Fa3: After the bag is opened, the control unit turns off the electromagnet, resets the sliding linkage, and uses gas to impact the dust at the bottom of the bag and impacts the dust on the outside of the bag, thus pushing it open.

[0030] Step Fa4: Return to step B and continue to remove dust from the gas using a filter bag.

[0031] According to the above technical solution, the working steps of the bag filter deep dust removal are as follows:

[0032] Step Fb1: The control unit shuts down the induced draft fan, stopping the filter bag from removing dust from the airflow;

[0033] Step Fb2: The control unit drives the electromagnet to work, pulling the sliding link upward along the inside of the fixed column, so that the sliding link does not limit the bottom of the bag;

[0034] Step Fb3: The control unit drives the transfer pump to work, inputting the external cleaning solution into the filter through the infusion tube, and then inputting the cleaning solution into the collection chamber through the filter.

[0035] Step Fb4: The control unit drives the output cylinder to work, moving the output linkage vertically. By rotating the linkage, the bag frame moves downward until the bottom of the bag fixed by the bag frame falls into the collection chamber.

[0036] Step Fb5: The control unit drives the rotary motor to work, which drives the bag frame to rotate through the rotating linkage, thereby causing the bottom of the bag to rotate in the cleaning solution inside the collection chamber. The bottom of the bag is cleaned by stirring the cleaning solution.

[0037] Step Fb6: After the bag cleaning is completed, the control unit drives the output cylinder to work, moving the output linkage vertically. By rotating the linkage, the bag frame is moved upward until the bag frame is reset.

[0038] Step Fb7: The control unit drives the booster pump to work, and inputs high-pressure gas into the interior of each set of filter bags through the air outlets of several sets of air supply pipes, blowing the water absorbed by the filter bags into the interior of the collection chamber.

[0039] Step Fb8: After the bag is dry, the control unit will turn off the electromagnet, reset the sliding linkage, and continue to fix the bag.

[0040] Step Fb9: The control unit drives the transfer pump to work, and discharges part of the cleaning solution inside the collection chamber into the infusion tube through the filter, and then discharges it outward through the infusion tube.

[0041] Step Fb10: The solution mixed with dust flows into the collection bucket through the bottom of the filter. The user collects the solution mixed with dust through the collection bucket and dries the solution through subsequent operations to extract the dust mixed inside.

[0042] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the present invention is in use, the dust removal of the filter bags can be carried out through the system, and the filter bags can be cleaned in time when they are blocked, so as to avoid insufficient air pressure of the overall equipment due to filter bag blockage, and thus avoid damage to the cyclone separator or other equipment in front of the equipment due to low air pressure. At the same time, the overall cleaning of the filter bags through the system can reduce the time spent by the user on cleaning the filter bags, thereby improving the overall dust removal efficiency.

The collection mechanism is located at the bottom of the fixing mechanism and is used to collect the dust removed by the dust removal mechanism. The data module is used to drive the fixing mechanism, the dust removal mechanism, and the collection mechanism to work and remove dust from the filter bag.

[0053] The fixing mechanism includes a support frame 1, a dust collector 2 on top of the support frame 1, a top cover 3 on top of the dust collector 2, several sets of cover plates 26 on top of the top cover 3, a support plate 4 at the bottom of the top cover 3, the support plate 4 being located on top of the dust collector 2, a bag holder 5 slidably connected inside the support plate 4, a sealing component at the connection between the support plate 4 and the bag holder 5, a limit block 6 on one side of the top of the bag holder 5, several sets of placement slots 25 for placing bags on the top of the bag holder 5, and fixing posts 7 for fixing the bags inside the placement slots 25 respectively. The fixing posts 7 are hollow structures. Each set of fixed columns 7 is internally connected to a sliding connecting rod 8. Each set of fixed columns 7 is topped with an electromagnet 9. The tops of the sliding connecting rods 8 are made of magnetic material. When the system is in use, the dust collector 2 is used to provide a sealed environment for dust removal from the gas. The sealing components are contact seals, such as Z-type seals or V-type seals, or labyrinth seals + oil groove seals + oil slingers or labyrinth seals + oil groove seals + oil slingers triple combination non-contact seals. The limiting block 6 is used to prevent the bag holder 5 from falling to the bottom of the support plate 4. The electromagnet 9 is used to provide attraction to the sliding connecting rod 8, driving the sliding connecting rod 8 to move inside the fixed column 7.

[0054] The dust removal mechanism includes an air inlet pipe 10, the end of which is connected to a pipe on one side of the dust collector 2. A pipe on one side of the top cover 3 is connected to an exhaust pipe 11, and an exhaust fan 12 is installed at the end of the exhaust pipe 11. A booster pump 13 is installed on the outside of the top cover 3. The output pipe of the booster pump 13 is connected to several sets of air delivery pipes 14. Several sets of air delivery pipes 14 are located at the top of the bag frame 5. Several sets of air delivery holes 15 are installed at the bottom of the several sets of air delivery pipes 14. A wind pressure detection sensor is installed inside the exhaust fan 12. When the system is in use, the air delivery holes 15 correspond to the top of each set of placement slots 25. The air delivery holes 15 are used to increase the wind pressure output by the booster pump 13 and push the high-pressure air into the interior of the bag through the fixed column 7.

[0055] The collection mechanism includes a collection chamber 16, a filter 17 connected to the bottom pipe of the collection chamber 16, an infusion pipe 18 connected to the outer pipe of the filter 17, a transfer pump 19 at the end of the infusion pipe 18, and a collection bucket 20 at the bottom of the filter 17. When the system is in use, the collection chamber 16 is used to collect the blown dust, the transfer pump 19 is used to deliver cleaning solution into the collection chamber 16 through the infusion pipe 18, and at the same time, the cleaning solution inside the collection chamber 16 is discharged out through the infusion pipe 18. The filter 17 is used to filter the mixed solution in this process, filtering the solids in the mixed solution into the collection bucket 20.

[0056] An output cylinder 21 is provided on the outside of the support frame 1. The output end of the output cylinder 21 is connected to an output connecting rod 22. A rotary motor 23 is installed at the end of the output connecting rod 22. The output end of the rotary motor 23 is connected to a rotary connecting rod 24. The outer surface of the rotary connecting rod 24 is connected to the top bearing of the top cover 3. The bottom of the rotary connecting rod 24 is fixed to the top of the bag frame 5.

[0057] The data module includes a detection unit, a judgment unit, and a control unit. The detection unit is located inside the wind pressure detection sensor and is used to detect the wind pressure during the operation of the induced draft fan 12. The judgment unit is electrically connected to the detection unit and is used to receive the data information detected by the detection unit and to judge the received data information. The control unit is electrically connected to the judgment unit, the electromagnet 9, the induced draft fan 12, the booster pump 13, the transfer pump 19, the output cylinder 21, and the rotary motor 23. It is used to receive the judgment result of the judgment unit and control the electromagnet 9, the induced draft fan 12, the booster pump 13, the transfer pump 19, the output cylinder 21, and the rotary motor 23 through the received data information to perform dust removal on the filter bag.

[0058] The working steps of the bag filter dust collection system are as follows: Open several sets of cover plates 26, place the filter bags to be collected into several sets of placement slots 25, and place several sets of fixing columns 7 inside the filter bags to secure them. The control unit drives the induced draft fan 12 to operate at its rated output power, drawing airflow from inside the inlet pipe 10 into the dust collection tank 2, and then drawing the airflow out through the exhaust pipe 11. During the gas movement, dust in the gas is separated by the filter bags, and the gas removes dust adsorbed on the outer surface of the filter bags. The control unit drives the rotary motor 23 to operate, causing the rotating connecting rod 24 to rotate, which in turn rotates the bag frame 5, rotating several sets of filter bags respectively. The high-speed airflow at the air inlet of the air inlet duct 10 removes dust from the outer surface of the filter bags. During the dust removal process, the control unit drives the booster pump 13 to operate intermittently, discharging the high-speed airflow through several sets of air outlets 15 at the bottom of the air outlet duct 14 to remove dust from the several sets of filter bags placed inside the filter bag frame 5. Specifically, the high-speed airflow enters the interior of the filter bags and moves outward, pushing out the dust adsorbed on the surface of the filter bags. During the dust removal process, the detection unit continuously detects the air pressure during the operation of the induced draft fan 12 and transmits the detected data to the judgment unit. Specifically, the real-time air pressure of the induced draft fan 12 is recorded as follows: The wind pressure when the induced draft fan 12 is running at its rated output power and there is no dust on the surface of the filter bag is recorded as follows: The judgment unit judges the received data information and transmits the judgment result to the control unit. The control unit controls the electromagnet 9, booster pump 13, transfer pump 19 and output cylinder 21 according to the received data information to clean the cloth bag. The dust blown off by the airflow falls into the inside of the collection chamber 16 and falls into the inside of the collection bucket 20 through the filter 17. The user collects the dust through the collection bucket 20.

[0059] The specific judgment process in this process is as follows:

[0060] when ≥0.8 At this point, the degree of blockage in the filter bag has no impact on the overall operation of the device, and it is determined that there is no need to clean the filter bag;

[0061] when At this point, the degree of clogging of the filter bag has a general impact on the overall operation of the device, and it is determined that basic dust removal of the filter bag is necessary.

[0062] when At this point, the degree of clogging of the filter bags has a significant impact on the overall operation of the equipment, indicating the need for deep dust removal. When the filter bags are clogged, they create resistance to the airflow within the equipment, thus reducing the overall air pressure. While moderate clogging usually results in less dust adsorbed on the bag surface, and cleaning is often achieved through airflow impact, timely cleaning is still necessary. Failure to do so will worsen the clogging, eventually leading to severe blockage. Severe clogging further obstructs the airflow, reducing air pressure and impacting the overall operation of the equipment. The blockage can affect the production line and, in severe cases, damage upstream equipment. When the filter bags become severely clogged, users need to clean them further for continued use. This often involves disassembling several sets of filter bags one by one and cleaning them manually. Therefore, by judging the degree of blockage and cleaning the filter bags accordingly, the blockage can be addressed promptly, preventing further severe blockage. Furthermore, when the filter bags become severely clogged, the equipment can clean several sets of filter bags at once, eliminating the need for manual cleaning by the user. This reduces the time operators spend cleaning the filter bags and significantly improves cleaning efficiency.

[0063] The basic dust removal process of the bag filter is as follows: The control unit drives the electromagnet 9 to work, pulling the sliding link 8 upward along the inner side of the fixed column 7, so that the sliding link 8 does not limit the bottom of the bag. The control unit drives the booster pump 13 to work continuously, and inputs high-pressure gas into the interior of each bag through the air outlet 15 of several sets of air outlet pipes 14, so that the bottom of the bag is opened by the high-pressure gas, and the dust on the outside of the bag is pushed away by the impact force of the high-pressure gas flowing out from the inside of the bag. After the bag is opened, the control unit closes the electromagnet 9 and resets the sliding link 8. The gas impacts the dust at the bottom of the bag and the impact force impacts the dust on the outside of the bag, pushing it away.

[0064] The working steps of bag filter deep dust removal are as follows: The control unit shuts off the induced draft fan 12, stopping the bag filter from removing dust from the airflow. The control unit drives the electromagnet 9 to pull the sliding link 8 upward along the inner side of the fixed column 7, so that the sliding link 8 does not limit the bottom of the bag. The control unit drives the transfer pump 19 to input the external cleaning solution into the filter 17 through the infusion pipe 18, and then inputs the cleaning solution into the collection chamber 16 through the filter 17. The control unit drives the output cylinder 21 to move the output link 22 vertically, and drives the bag frame 5 downward through the rotating link 24 until the bottom of the bag fixed by the bag frame 5 falls into the collection chamber 16. The control unit drives the rotary motor 23 to rotate the bag frame 5 through the rotating link 24, thereby causing the bottom of the bag to rotate in the cleaning solution inside the collection chamber 16. The bottom of the bag is cleaned by stirring the cleaning solution. After the cleaning of the cloth bag is completed, the control unit drives the output cylinder 21 to work, moving the output connecting rod 22 vertically. The rotating connecting rod 24 drives the cloth bag frame 5 to move upward until the cloth bag frame 5 is reset. The control unit drives the booster pump 13 to work, inputting high-pressure gas into the inside of each group of cloth bags through the air outlets 15 of several sets of air supply pipes 14, blowing the water absorbed by the cloth bag into the inside of the collection chamber 16. After the cloth bag is dry, the control unit closes the electromagnet 9, resets the sliding connecting rod 8, and continues to fix the cloth bag. The control unit drives the transfer pump 19 to work, discharging part of the cleaning solution inside the collection chamber 16 into the infusion pipe 18 through the filter 17, and then discharging it outward through the infusion pipe 18. The solution mixed with dust flows into the inside of the collection bucket 20 through the bottom of the filter 17. The user collects the solution mixed with dust through the collection bucket 20 and dries the mixed solution through subsequent operations to extract the dust mixed inside.

[0065] Since the air inlet of this equipment is often connected to devices such as cyclone separators for preliminary dust removal of the airflow, and the airflow required by the upstream equipment is provided by the exhaust fan of this equipment, using this system to remove dust from the filter bags can promptly clean the filter bags when they become clogged. This prevents insufficient air pressure in the overall equipment due to filter bag blockage, thus avoiding damage to the cyclone separator or other equipment upstream of this equipment due to excessively low air pressure. Furthermore, because this equipment holds a large number of filter bags, when there is excessive dust on the surface of the bags, operators must remove each bag individually, clean and dry them manually. Even when the dust on the surface of the bags is not severely clogged and does not require special cleaning, the operation of the entire equipment must be stopped, which is time-consuming and labor-intensive, resulting in low cleaning efficiency. Therefore, using this system to clean the filter bags as a whole can reduce the time spent by users on cleaning the filter bags, thereby improving the overall dust removal efficiency.
