Description

Technical Field

[0001] This disclosure relates to the field of waste gas purification and dust recovery technology, and in particular to an integrated device for waste gas purification and dust recovery in the process of cotton production. Background Technology

[0002] During the cotton production process, processes such as ginning, cleaning, and carding generate a large amount of dust-laden waste gas. This waste gas contains not only solid waste particles such as cotton lint and fiber fragments, but also small amounts of volatile organic compounds (VOCs), odorous gases, and other pollutants. If directly emitted, it will cause air pollution, harming the surrounding ecological environment and human health. Furthermore, recyclable resources such as cotton lint in the waste gas will be wasted, creating a potential solid waste pollution hazard, which does not meet the development needs of green production and resource recycling.

[0003] Existing waste gas purification and dust recovery devices typically employ a water-washing purification structure. However, during the cotton processing and production process, a large amount of complex waste gas is continuously generated, consisting of a mixture of fine cotton dust, short fibers, and various gaseous pollutants. The fibrous impurities such as cotton lint and cotton clumps carried in the waste gas easily adhere to the inner wall and pipeline structure of the water-washing device. Over time, this accumulation can cause blockages in the water holes, spray nozzles, and flow channels, leading to a decrease in the device's purification efficiency and an increase in operating resistance. At the same time, traditional water-washing purification equipment generally suffers from cumbersome water replacement operations and inconvenient sewage discharge and cleaning. After the equipment has been running continuously for a long time, pollutants accumulate in the circulating water, and the water quality deteriorates. It is impossible to replace the water in a timely and efficient manner, which seriously reduces the waste gas treatment effect and makes it difficult to meet the continuous and stable environmental purification operation requirements of cotton production lines.

Guide inclined plates 13 are fixedly connected to both sides of the vertical plate 12. A touch switch 15 is fixedly installed on the top of the vertical plate 12.

[0021] In some embodiments, the primary pre-filter assembly 4 includes a closed frame 401 slidably fitted onto the inner wall of the air intake frame 3. A partition on the inner wall of the closed frame 401 divides its internal space into two independent separation chambers 402. A filter cylinder 403 with multiple holes is fixedly connected between the upper and lower plates of each of the two separation chambers 402. Both ends of the filter cylinder 403 penetrate the upper and lower plates of the separation chamber 402 to the outside, and the bottom of the filter cylinder 403 is open. The air outlet of the air intake channel 8 corresponds to the opening at the bottom of the filter cylinder 403. The two filter cylinders 403... Piston plates 404 slide vertically on the inner walls of the filter cylinder 403. A connecting rod 405 is fixedly connected to the upper side of the piston plate 404. The top end of the connecting rod 405 passes through the top plate of the filter cylinder 403 and is fixedly connected to an abutment block 406. The top of the abutment block 406 is arc-shaped and abuts against the lower side of the guide inclined plate 13. The abutment block 406 cooperates with the touch switch 15. The inner walls of the two separation chambers 402 are provided with first ventilation slots 407 extending outward. The inner wall of the air inlet frame 3 is provided with second ventilation slots 408 extending outward. The bottom of the closed frame 401... Limiting plates 409 are fixedly connected to both sides of the part; wherein, the first ventilation slot 407 and the second ventilation slot 408 are correspondingly arranged, a servo motor 16 is fixedly installed in the groove at the bottom of the base plate 1, the output shaft of the servo motor 16 is fixedly connected to a transmission rod 17, a screw 18 is rotatably fitted on one side of the base plate 1, and one end of the screw 18 and the periphery of the transmission rod 17 are fixedly connected to bevel gears 19; wherein, the servo motor 16 is electrically connected to a touch switch 15, the two bevel gears 19 mesh with each other, and gears 20 are fixedly connected to the periphery of the transmission rod 17. A rack 21 is fixedly connected between the limiting plates 409. A displacement groove 23 is provided on the outer wall of the air intake frame 3. A displacement block 24 is slidably fitted on the inner wall of the displacement groove 23. A connecting groove 30 is provided through the upper side of the displacement block 24. A connecting column 26 is fixedly connected to the inner wall of the connecting groove 30. The gear 20 meshes with the rack 21. A cylindrical cam 25 is fixedly connected to the periphery of the transmission rod 17. The connecting groove 30 is slidably fitted on the periphery of the cylindrical cam 25. The connecting column 26 rotates and slidably fits in the groove on the periphery of the cylindrical cam 25.

[0022] Understandably, the air enters the intake channel 8 of the intake frame 3 through the corrugated intake pipe 9, and then precisely enters the bottom opening of the filter cartridge 403 in the primary pre-filtration component 4 through the outlet of the intake channel 8. When the exhaust gas flows upward through the filter cartridge 403, the holes in the inner wall of the filter cartridge 403 can effectively intercept larger cotton clumps, lint, and coarse dust particles in the exhaust gas, completing the preliminary filtration operation. The exhaust gas after preliminary filtration enters the second ventilation slot 408 of the intake frame 3 through the first ventilation slot 407 on the inner wall of the separation chamber 402, successfully completing the primary pre-filtration stage. As the filtration process continues, cotton dust and fibrous impurities gradually adhere to the inner wall of the filter cartridge 403, increasing the resistance to gas flow. This, in turn, pushes the piston plate 404 upward. The piston plate 404, through the connecting rod 405, drives the abutment block 406 to move upward synchronously. After the abutment block 406 continues to move upward, it touches the touch switch 15, triggering the servo motor 16 to start. The output shaft of the servo motor 16 drives the transmission rod 17 to rotate. The gear 20 on the transmission rod 17 meshes with the rack 21 between the limit plate 409, driving... The closing frame 401 slides on the inner wall of the air intake frame 3, realizing the alternating switching of the two separation chambers 402 (one continuously performs filtration, and the other performs cleaning simultaneously); while the closing frame 401 moves the connecting rod 405, the top of the abutting block 406 abuts against the guide inclined plate 13, thereby realizing the downward movement of the piston plate 404, pushing off the dust and fiber impurities adhering to the inner wall of the filter cylinder 403. The pushed-off impurities fall into the collection box 11 slidably installed on the bottom plate 1, completing the recovery of large impurities such as cotton balls.

[0023] In some embodiments, the secondary water washing and purification assembly 5 includes a water washing tank 501 fixedly connected to the upper side of the base plate 1. A sedimentation tank 502 and a water supply tank 503 are fixedly connected to one side of the water washing tank 501. The water supply tank 503 is located above the sedimentation tank 502. A drain pipe 504 communicating with the sedimentation tank inside the sedimentation tank 502 is fixedly connected to one side of the sedimentation tank 502. A third ventilation slot 505 is provided through the side plate of the water washing tank 501. A plurality of baffles 506 are fixedly connected to the inner wall of the water washing tank 501, and wave-making ports 507 are formed between the plurality of baffles 506. The washing tank 501 has a clean water inlet 508 on the upper side plate and a wastewater outlet 509 on the lower side plate. The third vent 505 is correspondingly and connected to the second vent 408. The outlet of the water tank 503 is fixedly connected to and connected to the clean water inlet 508 of the washing tank 501. A wastewater inlet 510 is provided through the side plate of the sedimentation tank 502. A sliding opening plate 511 is provided between the washing tank 501 and the sedimentation tank 502. A connecting groove 512 is provided through one side of the opening plate 511. In this configuration, the sewage outlet 509 is correspondingly positioned to the sewage inlet 510, and the connecting channel 512 is correspondingly positioned to both the sewage outlet 509 and the sewage inlet 510. A connecting frame 27 is fixedly connected to one side of the displacement block 24, and a connecting sleeve 28 is fixedly connected to one end of the connecting frame 27. A threaded groove 29 is provided on one side of the opening and closing plate 511; the threaded groove 29 is threadedly engaged with the screw 18. A solenoid valve 513 is fixedly installed on one side of the washing tank 501, and water pipes 514 are fixedly connected to both the inlet and outlet ends of the solenoid valve 513. The sedimentation tank 50... Both the outer walls of the water tank 503 and the water supply tank 503 are fixedly connected to water pipes 515. A break is provided between the two water pipes 515. The connecting sleeve 28 is located at the break and fits into the two water pipes 515. A pump body 516 is fixedly installed on one side of the water supply tank 503. The pump body 516 fits into the water pipes 515 on the water supply tank 503. The water supply pipe 514 at the inlet end of the solenoid valve 513 is fixedly connected to and communicates with the washing tank 501. The water supply pipe 514 at the outlet end of the solenoid valve 513 is fixedly connected to and communicates with the sedimentation tank 502.

[0024] It should be noted that the exhaust gas after primary pre-filtration is connected to the third ventilation slot 505 of the water washing tank 501 through the second ventilation slot 408 and smoothly enters the water washing tank 501 of the secondary water washing purification component 5; the water supply tank 503 injects clean water into the water washing tank 501 through the clean water inlet 508. The exhaust gas passes through the wave-making port 507 formed by multiple baffles 506 in the water washing tank 501 and fully contacts and collides with the water. The soluble gaseous pollutants remaining in the exhaust gas are adsorbed by the water, thus achieving secondary water washing purification. Wastewater generated during the washing process can be discharged through the wastewater outlet 509 below the washing tank 501. When the two separation chambers 402 are switched alternately, the screw 18 and the threaded groove 29 of the opening and closing plate 511 cooperate with each other, causing the opening and closing plate 511 to slide, so that the connecting groove 512 on the opening and closing plate 511 precisely corresponds to the wastewater outlet 509 and the wastewater inlet 510 of the sedimentation tank 502, and the wastewater smoothly enters the sedimentation tank 502 for sedimentation treatment. The sedimented wastewater can be discharged through the drain pipe 504. At the same time, the connecting sleeve 28 can connect to the water pipe 515 between the sedimentation tank 502 and the water supply tank 503, and cooperate with the continuously running pump body 516 to realize water recycling. When the two separation chambers 402 are not switched, the wastewater in the sedimentation tank 502 is in a static sedimentation state. In addition, the solenoid valve 513 can introduce the sewage in the washing tank 501 into the sedimentation tank 502 through the water supply pipe 514 to ensure the stability of the washing water quality. The solenoid valve 513 can be manually controlled without waiting for the two separation chambers 402 to switch. It can be manually controlled to open and close the chambers to realize the water in the sedimentation tank 502 to be transported to the washing tank 501 for circulation.

[0025] Working principle: This integrated device for waste gas purification and dust recovery during cotton production uses a multi-stage treatment process of "first-stage pre-filtration + second-stage water washing purification + activated carbon deep adsorption" to achieve simultaneous completion of waste gas purification and dust recovery, with all components operating in synergy. The waste gas is introduced and initially separated from the dust. The complex waste gas generated from cotton production, consisting of mixed fine cotton dust, short fibers, and gaseous pollutants, enters the intake channel 8 of the intake frame 3 through the corrugated intake pipe 9. The waste gas then enters the bottom opening of the filter cylinder 403 in the primary pre-filtration component 4 through the outlet of the intake channel 8, flowing upward through the filter cylinder 403. The pores on the inner wall of the filter cylinder 403 can intercept larger cotton clumps, cotton fibers, and coarse dust particles in the waste gas, achieving preliminary filtration. The pre-filtered waste gas enters the second ventilation slot 408 of the intake frame 3 through the first ventilation slot 407 on the inner wall of the separation chamber 402, completing the primary pre-filtration stage. As the filtration operation continues, cotton dust and fiber impurities adhere to the inner wall of the filter cylinder 403, increasing the gas flow resistance and pushing the piston plate 404 to slide upward. The piston plate 404 drives the abutment block 406 to move upward through the connecting rod 405, and after moving upward, it touches the touch switch 15, triggering the process. When the servo motor 16 starts, the output shaft of the servo motor 16 drives the transmission rod 17 to rotate. The gear 20 on the transmission rod 17 meshes with the rack 21 between the limit plate 409, causing the closing frame 401 to slide on the inner wall of the air intake frame 3, realizing the alternating switching of the two separation chambers 402. While the closing frame 401 drives the connecting rod 405 to move, the piston plate 404 moves downward because the top of the abutting block 406 abuts against the guide inclined plate 13, pushing the dust and fiber impurities adhering to the inner wall of the filter cartridge 403 into the collection box 11 that is slidably installed on the bottom plate 1, thus completing the recovery of large impurities such as cotton balls. The secondary water washing deep purification process involves the exhaust gas, after primary pre-filtration, entering the water washing tank 501 of the secondary water washing purification component 5 through the second ventilation slot 408 and the third ventilation slot 505. The water supply tank 503 injects purified water into the water washing tank 501 through the purified water inlet 508. Inside the water washing tank 501, the exhaust gas passes through the wave-making opening 507 formed by multiple baffles 506, ensuring full contact and collision with the water. Residual soluble gaseous pollutants in the exhaust gas are adsorbed by the water, achieving secondary water washing purification. Wastewater generated during the washing process is discharged through the wastewater outlet 509 at the bottom of the water washing tank 501. Simultaneously, as the two separation chambers 402 alternate, the screw 18 engages with the threaded groove 29 of the opening and closing plate 511, causing the opening and closing plate 511 to slide. This allows the connecting groove 512 on the opening and closing plate 511 to connect with the wastewater outlet 509 and the sedimentation tank 502. Corresponding to the sewage inlet 510, sewage enters the sedimentation tank 502 for sedimentation treatment. The settled sewage can be discharged through the drain pipe 504. At the same time, the connecting sleeve 28 can connect to the water pipe 515 between the sedimentation tank 502 and the water supply tank 503, and work with the pump body 516 to realize water recycling. The pump body 516 is in a continuously open state. When the two separation chambers 402 are not switched, the sewage in the sedimentation tank 502 is in a static sedimentation state. The solenoid valve 513 can introduce the sewage in the washing tank 501 into the sedimentation tank 502 through the water supply pipe 514 to ensure the stability of the washing water quality. The solenoid valve 513 can be manually controlled. It is not necessary to switch the two separation chambers 402 to draw water from the sedimentation tank 502 for circulation. The water in the sedimentation tank 502 can be transported to the washing tank 501 for water circulation by manually controlling the opening and closing of the solenoid valve 513. Deep adsorption and emission compliance: After secondary water washing purification, the exhaust gas enters the exhaust fan 10 from the outlet at the top of the water washing tank 501 under the action of the exhaust fan 10, and then is introduced into the activated carbon adsorption purification tank 6 from the outlet of the exhaust fan 10. The modified high-efficiency activated carbon material filled inside the activated carbon adsorption purification tank 6 can further adsorb the residual gaseous pollutants in the exhaust gas to achieve deep purification. Finally, the purified exhaust gas is discharged in compliance through the exhaust pipe 7 on one side of the activated carbon adsorption purification tank 6. The primary pre-filtration component 4, the secondary water washing purification component 5 and the activated carbon adsorption purification tank 6 of the entire device are all covered by the protective frame 2, which plays a protective and integrated role, ensuring the stable operation of the device.
