Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly relates to a waste gas treatment device for a chemical reaction kettle. Background Art

[0002] Chemical waste gas refers to the toxic and harmful gases discharged from chemical plants during chemical production. Chemical waste gas often contains many types of pollutants, with complex physical and chemical properties and different toxicities, seriously polluting the environment and affecting human health.

[0003] There are many toxic substances in chemical waste gas, but they can be roughly divided into water-soluble toxic substances and water-insoluble toxic substances. Therefore, waste gas treatment can also be carried out according to this aspect; however, existing waste gas treatment equipment discharges waste gas after treating the water-soluble toxic substances, or only adsorbs and treats the toxic gases, resulting in incomplete waste gas treatment and causing environmental pollution to varying degrees.

[0004] Therefore, a waste gas treatment device for a chemical reaction kettle is needed. This device can first treat the water-soluble toxic substances in the gas to complete the first step of waste gas treatment; it can separate water and gas from the waste gas after water treatment to ensure that the waste gas is in a dry state when treating the water-insoluble toxic substances in the waste gas, which is beneficial to improving the adsorption capacity of the water-insoluble toxic substances and completing the second step of waste gas treatment; it can further adsorb the water-insoluble toxic substances and clean the filter plate, which is beneficial to improving the adsorption efficiency of the filter plate. At the same time, the filter plate can be disassembled and replaced, with simple and convenient operation, further improving the waste gas treatment efficiency. Summary of the Invention

A horizontal groove is provided in the middle of the scraping frame 404, and scraping plates are fixedly installed on both the upper and lower sides of the horizontal groove. A clamping rod is fixedly installed on the outside of the scraping frame 404; the push rod 405 is slidably installed in the round hole on the side of the vertical frame 403; specifically, when scraping the impurities on the filter plate 503, the lead screw slider group 401 works, the lead screw slider group 401 drives the corresponding vertical frame 403 to move, the vertical frame 403 drives the scraping frame 404 to move, and the two scraping plates on the scraping frame 404 scrape off the impurities on both the upper and lower sides of the filter plate 503 on the clamping frame 501 aligned with its horizontal groove.

[0037] As Figure 12 shown in the figure, the lead screw slider group 401 includes a frame, a lead screw, a motor, and a slider. The frame is fixedly installed on the side of the housing 101, the lead screw is rotatably installed in the frame, the motor is fixedly installed on the frame, its motor shaft is fixedly connected to one end of the lead screw, the slider is slidably installed in the frame, and the threaded hole on the slider is in threaded cooperation with the lead screw.

[0038] As Figure 12 shown in the figure, a spring is installed at the rear of the push rod 405, and the other end of the spring is connected to the plate on the side of the vertical frame 403.

[0039] As Figure 12As shown, the cleaning mechanism 4 further includes: Gear III 406, Gear IV 407, Gear V 408, Gear VI 409, Gear Set I 410, Gear Set II 411, electric cylinder 412, cross plate 413 and the housing mechanism 1 of the cleaning mechanism 4; The shafts of Gear III 406 and Gear V 408 are respectively rotatably installed in the upper and lower circular holes of a rectangular block 102; The shafts of Gear IV 407 and Gear VI 409 are respectively rotatably installed in the upper and lower circular holes of another rectangular block 102; Gear Set I 410 is rotatably installed in the upper circular hole of the front side plate of the outer housing 101, and the shafts of the two gears in Gear Set I 410 are respectively connected to the shafts of Gear III 406 and Gear IV 407 through synchronous belts; Specifically, when Gear Set I 410 rotates, it drives Gear III 406 and Gear IV 407 to rotate in opposite directions simultaneously; Gear Set II 411 is rotatably installed in the lower circular hole of the front side plate of the outer housing 101, and the shafts of the two gears in Gear Set II 411 are respectively connected to the shafts of Gear V 408 and Gear VI 409 through synchronous belts; Specifically, when Gear Set II 411 rotates, it drives Gear V 408 and Gear VI 409 to rotate in opposite directions simultaneously; The cylinder part of the electric cylinder 412 is fixedly installed on the U-shaped frame 103, and the piston rod end of the electric cylinder 412 is fixedly connected to the cross plate 413; The housing mechanism 1 of the cleaning mechanism 4 is fixedly installed on the cross plate 413, and its motor shaft is fixedly connected to a gear, and this gear meshes with Gear Set I 410 and Gear Set II 411 intermittently; Specifically, when Gear Set I 410 needs to rotate, the electric cylinder 412 works, the electric cylinder 412 pushes the cross plate 413 to move upward, the cross plate 413 drives the housing mechanism 1 of the cleaning mechanism 4 to move upward, and the housing mechanism 1 of the cleaning mechanism 4 drives the gear on its shaft to mesh with Gear Set I 410. At this time, the housing mechanism 1 of the cleaning mechanism 4 starts, drives Gear Set I 410 to rotate, Gear Set I 410 drives Gear III 406 and Gear IV 407 to rotate in opposite directions simultaneously, and Gear III 406 and Gear IV 407 drive the two upper racks 502 corresponding to them to move outward simultaneously. The two upper racks 502 drive the two upper card frames 501 to move outward simultaneously, and the two upper card frames 501 drive the filter plate 503 thereon to move outward, so that the upper filter plate 503 completely moves out of the outer housing 101. At the same time, when the cross plate 413 moves upward, the card holes on the limit blocks on the cross plate 413 drive the scraping frame 404 to move upward, so that the horizontal groove on the scraping frame 404 is aligned with the upper filter plate 503, facilitating the scraping of impurities on the two upper filter plates 503. When the scraping frame 404 moves upward to a suitable position, the ejector rod 405 pushes the scraping frame 404 into the vertical frame 403, making the scraping frame 404 unable to move; When the gear set II 411 needs to rotate, the electric cylinder 412 works. The electric cylinder 412 pulls the cross plate 413 downward. The cross plate 413 drives the cleaning mechanism 4 and the housing mechanism 1 and the cleaning mechanism 4 downward. The cleaning mechanism 4 and the housing mechanism 1 and the cleaning mechanism 4 drive the gears on its shaft to mesh with the gear set II 411. At this time, the cleaning mechanism 4 and the housing mechanism 1 and the cleaning mechanism 4 start, driving the gear set II 411 to rotate. The gear set II 411 drives the gear V 408 and the gear VI 409 to rotate in the opposite direction simultaneously. The gear V 408 and the gear VI 409 drive the two corresponding lower racks 502 to move outward simultaneously. The two lower racks 502 drive the two lower card frames 501 to move outward simultaneously. The two lower card frames 501 drive the filter plate 503 thereon to move outward, so that the lower filter plate 503 completely moves out of the housing 101. At the same time, when the cross plate 413 moves downward, the card holes on the limit blocks on the cross plate 413 drive the scraping frame 404 downward, so that the horizontal groove on the scraping frame 404 is aligned with the lower filter plate 503; it is convenient to scrape the impurities on the two lower filter plates 503. When the scraping frame 404 moves downward to a suitable position, the ejector rod 405 pushes the scraping frame 404 into the vertical frame 403, making the scraping frame 404 unable to move.

The side water inlet of the spraying assembly 204 is connected to an external water source through a pipe, and a plurality of spray heads are fixedly installed on the spraying assembly 204; when the external waste gas enters the lower shell 201 from the air inlet pipe 202, the intelligent electric control makes the spray heads on the spraying assembly 204 spray water outward. Since a plurality of spray heads on the spraying assembly 204 spray water outward simultaneously, the toxic substances that can dissolve in water in the lower shell 201 are fully mixed with water to form waste water, and flow out from the water outlet at the lower end of the lower shell 201.

Specifically, when the round rod 311 rotates, it drives the fan 310 to rotate, and the outer end of the round rod 311 is connected to the shafts of the corresponding pinion II 305 and pinion I 304 through a synchronous belt; specifically, when the pinion I 304 rotates, it drives the corresponding pinion II 305 to rotate, and further drives the corresponding round rod 311 to rotate; the funnel box 313 is fixedly installed at the lower end of the inner cylinder 308, an air inlet hole is provided at the lower end of the funnel box 313, a cylinder wall is provided around the air inlet hole, and a downward flow hole is opened inside the cylinder wall of the funnel box 313; the upper end of the hollow rod 312 is fixedly installed at the lower air inlet hole of the funnel box 313, and the lower end of the hollow rod 312 passes through the corresponding ventilation hole on the cover plate 203 and is rotatably connected to the ventilation hole; the water receiving box 314 is fixedly installed on the upper end surface of the cover plate 203 through a rod, the water receiving box 314 is rotatably connected to the lower end of the funnel box 313, a drainage pipe is fixedly installed on the side of the water receiving box 314, and the lower end of the downward flow hole inside the cylinder wall of the funnel box 313 is located above the water receiving box 314, that is, the waste liquid flowing out of the downward flow hole inside the cylinder wall of the funnel box 313 can completely enter the water receiving box 314 and flow out of the device through the drainage pipe on the side of the water receiving box 314;Specifically, after filtering out the harmful substances soluble in water inside the lower shell 201, the internal gas enters the corresponding hollow rod 312 through the ventilation holes on the cover plate 203 and then enters the inner cylinder 308. At this time, the motor I 303 starts, driving the large gear 302 to rotate. The large gear 302 drives the two small gears I 304 to rotate, and the two small gears I 304 drive the two inner cylinders 308 to rotate respectively. The two inner cylinders 308 drive the spiral plates 309 inside them to rotate. At this time, the gas introduced from the lower end of the inner cylinder 308 will be separated from water and gas under the rotation of the spiral plate 309. The separated wastewater flows out into the water receiving box 314 through the downward flow holes inside the barrel wall of the funnel box 313 and flows out of the device through the drainage pipe on the side of the water receiving box 314.

The clamping frames 501 in the four third filtering mechanisms 5 are clamped in the corresponding grooves at the upper end of the outer shell 101. The clamping frames 501 are aligned with the horizontal grooves on the corresponding scraping frames 404. And the four third filtering mechanisms 5 are respectively divided into upper and lower groups. The two clamping frames 501 in the upper group of the two third filtering mechanisms 5 are respectively slidably installed at the upper positions of the two filter boxes 307, and the two clamping frames 501 in the lower group of the two third filtering mechanisms 5 are respectively slidably installed at the lower positions of the two filter boxes 307. The racks 502 in the four third filtering mechanisms 5 are fixedly installed on the sides of the four clamping frames 501, and the four racks 502 are correspondingly meshed with the corresponding gear III 406, gear IV 407, 708, and gear VI 409. The filter plate 503 is slidably clamped on the inner wall of the clamping frame 501, and the filter plate 503 is used for adsorbing the toxic gas insoluble in water in the gas. The clamping frame 504 is slidably installed in the groove on the inner wall of the clamping frame 501, and the lower end of the clamping frame 504 is intermittently clamped with the clamping groove on the clamping frame 501.

[0045] Working principle: When treating the substances soluble in water in the waste gas, after the external waste gas enters the lower shell 201 from the air inlet pipe 202, the intelligent electric control spray component 204 sprays water outward through the nozzles. Since multiple nozzles on the spray component 204 spray water outward at the same time, the toxic substances soluble in water inside the lower shell 201 are fully mixed with water to form wastewater, which flows out from the water outlet at the lower end of the lower shell 201. When performing water-vapor separation, after filtering out harmful substances dissolved in water inside the lower shell 201, the internal gas enters the corresponding hollow rod 312 through the ventilation holes on the cover plate 203 and then enters the inner cylinder 308. At this time, the motor I 303 starts, driving the large gear 302 to rotate. The large gear 302 drives the two small gears I 304 to rotate. The two small gears I 304 drive the two inner cylinders 308 to rotate respectively. The two inner cylinders 308 drive the spiral plates 309 inside them to rotate. At this time, the gas introduced from the lower end of the inner cylinder 308 will be subjected to water-vapor separation under the rotation of the spiral plate 309. The separated waste water flows out to the water receiving box 314 through the downward flow holes inside the barrel wall of the funnel box 313 and flows out of the device through the drainage pipe on the side of the water receiving box 314. At the same time, the rotation of the small gear I 304 drives the corresponding round rod 311 to rotate, and the round rod 311 drives the fan 310 to rotate. The fan 310 assists the gas inside the inner cylinder 308 to move upward, realizing the separation of water and gas, which is beneficial to further treating the waste gas. At the same time, when adsorbing the dried gas again, it can further improve the adsorption efficiency of the water-insoluble toxic substances in the gas; After the dried waste gas is introduced into the corresponding filter box 307, first, the two upper filter plates 503 inside the outer shell 101 adsorb the toxic substances in the waste gas. At this time, the two lower filter plates 503 inside the outer shell 101 are located outside the outer shell 101. When it is necessary to clean the two upper filter plates 503, first, the cleaning mechanism 4 of the housing mechanism 1 starts, driving the gear on its shaft to rotate, and then driving the gear set II 411 to rotate. The gear set II 411 drives the gear V 408 and the gear VI 409 to rotate in opposite directions at the same time. The gear V 408 and the gear VI 409 drive the two lower racks 502 to move inward at the same time, and then drive the two lower casses 501 to move inward at the same time, and then drive the two lower filter plates 503 to move inward at the same time, so that the two lower filter plates 503 are completely moved to the lower positions of the two filter boxes 307 to perform the adsorption work of the toxic substances in the waste gas; When removing the two upper filter plates 503 from the housing 101 for cleaning, the electric cylinder 412 operates. The electric cylinder 412 pushes the cross plate 413 upward. The cross plate 413 drives the cleaning mechanism 4 and the housing mechanism 1 to move upward. The cleaning mechanism 4 and the housing mechanism 1 drive the gear on its shaft to engage with the gear set I 410. At this time, the cleaning mechanism 4 and the housing mechanism 1 start, driving the gear set I 410 to rotate. The gear set I 410 drives the gear III 406 and the gear IV 407 to rotate in opposite directions simultaneously. The gear III 406 and the gear IV 407 drive the two corresponding upper racks 502 to move outward simultaneously. The two upper racks 502 drive the two upper clamping frames 501 to move outward simultaneously. The two upper clamping frames 501 drive the filter plates 503 thereon to move outward, causing the upper filter plates 503 to be completely removed from the housing 101. At the same time, when the cross plate 413 moves upward, the card holes on the limit blocks on the cross plate 413 drive the scraping frame 404 to move upward, aligning the horizontal groove on the scraping frame 404 with the upper filter plate 503. When the scraping frame 404 moves upward to a suitable position, the ejector rod 405 pushes the scraping frame 404 into the vertical frame 403, preventing the scraping frame 404 from moving; Then, the lead screw slider group 401 operates. The lead screw slider group 401 drives the corresponding vertical frame 403 to move. The vertical frame 403 drives the scraping frame 404 to move. The two scraping plates on the scraping frame 404 scrape off the impurities on the upper and lower sides of the filter plate 503 on the upper clamping frame 501 aligned with its horizontal groove; this is beneficial to improving the adsorption efficiency of the filter plate 503; When removing the two lower filter plates 503 from the housing 101 for cleaning, first, the cleaning mechanism 4 and the housing mechanism 1 start, driving the gear on its shaft to rotate, and then driving the gear set I 410 to rotate. The gear set I 410 drives the gear III 406 and the gear IV 407 to rotate in opposite directions simultaneously. The gear III 406 and the gear IV 407 respectively drive the two upper racks 502 to move inward simultaneously, and then drive the two upper clamping frames 501 to move inward simultaneously, and then drive the two upper filter plates 503 to move inward simultaneously, causing the two upper filter plates 503 to be completely moved to the upper positions of the two filter boxes 307 for adsorbing the toxic substances in the waste gas; When the following two filter plates 503 are removed from the housing 101 for cleaning, the electric cylinder 412 operates. The electric cylinder 412 pulls the cross plate 413 downward. The cross plate 413 drives the cleaning mechanism 4 and the housing mechanism 1 downward. The cleaning mechanism 4 and the housing mechanism 1 drive the gear on its shaft to engage with the gear set II 411. At this time, the cleaning mechanism 4 and the housing mechanism 1 start, driving the gear set II 411 to rotate. The gear set II 411 drives the gear V 408 and the gear VI 409 to rotate in opposite directions simultaneously. The gear V 408 and the gear VI 409 drive the corresponding two racks 502 below them to move outward simultaneously. The two racks 502 below drive the two card frames 501 below them to move outward simultaneously. The two card frames 501 above drive the filter plates 503 on them to move outward, so that the lower filter plates 503 are completely removed from the housing 101. At the same time, when the cross plate 413 moves downward, the card holes on the limit blocks on the cross plate 413 drive the scraping frame 404 downward, so that the horizontal groove on the scraping frame 404 is aligned with the lower filter plate 503; when the scraping frame 404 moves downward to a suitable position, the ejector rod 405 pushes the scraping frame 404 into the vertical frame 403, making the scraping frame 404 unable to move; Then, the lead screw slider group 401 operates. The lead screw slider group 401 drives the corresponding vertical frame 403 to move. The vertical frame 403 drives the scraping frame 404 to move. The two scraping plates on the scraping frame 404 scrape off the impurities on the upper and lower sides of the filter plate 503 on the lower card frame 501 aligned with its horizontal groove; this is beneficial to improving the adsorption efficiency of the filter plate 503; thus alternately adsorbing the toxic gases in the waste gas to ensure the treatment effect of the waste gas. At the same time, the filter plate 503 is alternately cleaned to further ensure the adsorption effect of the filter plate 503; The filter plate 503 can be replaced. When replacing, manually push the card rack 504 upward so that the lower end of the card rack 504 disengages from the card slot on the card frame 501. Then, manually remove the old filter plate 503 and replace it with a new filter plate 503. Then, manually push the card rack 504 downward again so that the lower end of the card rack 504 is reinstalled in the groove on the card frame 501, realizing the replacement of the filter plate 503. The operation is simple, improving the equipment utilization rate and further improving the waste gas treatment efficiency.
