Technical Field

[0001] This invention relates to the field of purification equipment technology, specifically to a purification equipment for chemical waste gas recovery. Background Technology

[0002] Chemical waste gas recovery and purification equipment is a complete set of industrial environmental protection devices that remove pollutants and render toxic substances harmless by using physical, chemical, or biological methods to treat toxic waste gases generated during chemical production processes, such as toxic, harmful, flammable, explosive, malodorous, and volatile organic waste gases.

[0003] Chemical waste gas recovery and purification equipment purifies waste gas through physical or chemical methods inside the purification cylinder. The waste gas is collected and guided into the purification cylinder through external pipelines, thus achieving guided transmission and recycling of chemical waste gas.

[0004] Traditional chemical waste gas recovery and purification equipment often carries a lot of dust particles when treating chemical waste gas. These dust particles can clog the physical filter screen inside the purification cylinder after entering the waste gas, thus affecting the purification effect. Summary of the Invention

[0005] The purpose of this invention is to provide a chemical waste gas recovery and purification treatment device, which solves the problem that existing chemical waste gas recovery and purification treatment devices are inconvenient to treat dust particles in the waste gas during the purification treatment of chemical waste gas.

[0006] The present invention provides the following technical solution: a chemical waste gas recovery and purification treatment device, comprising a purification cylinder, a transmission cylinder fixedly connected to the upper end of the purification cylinder, a fixing ring fixedly connected to the inner side of the transmission cylinder away from the purification cylinder, and a filter screen fixedly connected to the inner side of the fixing ring by bolts, a driving component arranged on the outer side of the transmission cylinder near the filter screen, a transmission component arranged at one end of the driving component, a cleaning component arranged through the transmission cylinder at one end of the transmission component, a storage component arranged on the outer side of the upper end of the transmission cylinder, a spraying component arranged at the lower end of the storage component, a guiding component arranged at the lower end of the transmission cylinder, and a collection component arranged at the end of the guiding component away from the transmission cylinder.

Then, the drive component is activated to drive the transmission component and the cleaning component. The cleaning component cleans the surface of the filter screen, while the spray component draws out the cleaning water stored in the storage component and sprays it onto the surface of the filter screen. This works in conjunction with the cleaning component for cleaning. The cleaned wastewater is then injected into the collection component through the guide component for collection, thereby improving the purification effect of the exhaust gas and reducing the clogging of the physical filter screen inside the purification cylinder caused by the exhaust gas.

[0013] Through the above technical solution, the second gear drives the connecting plate and cleaning brush to rotate, and the rotation of the connecting plate and cleaning brush is used to clean the surface of the filter screen.

[0014] As a preferred embodiment of the above technical solution, the storage component includes a storage box fixedly connected to the upper side of the transmission cylinder near the filter screen, and an inlet is fixedly connected to the upper end of the storage box.

[0019] Through the above technical solution, the cleaned wastewater passes through the mesh plate and enters the conduit, and then is injected into the collection box for collection.

[0020] As a preferred embodiment of the above technical solution, the collection component includes a collection box fixedly connected to the lower end of the conduit away from the transmission cylinder, and a drain outlet fixedly connected to the lower end of the collection box.

[0021] With the above technical solution, wastewater is stored in the collection tank, and then discharged later by opening the drain outlet.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This is a chemical waste gas recovery and purification equipment. It filters and intercepts dust particles in the waste gas through a fixed ring and a filter screen. Then, the drive component is activated to drive the transmission component and the cleaning component.

[0032] like Figure 2As shown, the transmission assembly 4 includes a protective cover 41 fixedly connected to one side of the servo motor 31, and second bolt fasteners 42 fixedly connected to both ends of the protective cover 41. The second bolt fasteners 42 are threaded into the transmission cylinder 11 at the end near the transmission cylinder 11. The output shaft of the servo motor 31 is fixedly connected to a first gear 43 through the protective cover 41. The end of the first gear 43 away from the servo motor 31 is rotatably connected to the protective cover 41. A toothed belt 44 is sleeved on the outside of the first gear 43. A second gear 45 is inserted into the inside of the end of the toothed belt 44 away from the first gear 43. One end of the second gear 45 is rotatably connected to the protective cover 41. The protective cover 41 is fixedly connected to the transmission cylinder 11 by the second bolt fasteners 42. After the servo motor 31 is started, the output shaft drives the first gear 43 to rotate, and then drives the second gear 45 to rotate through the first gear 43 and the toothed belt 44, thereby allowing the second gear 45 to drive the connecting plate 51 and the cleaning brush 52 to rotate.

[0033] like Figure 2 As shown, the cleaning assembly 5 includes a second gear 45 that is fixedly connected to a connecting plate 51 through the protective cover 41 on one side, and a cleaning brush 52 that is fixedly connected to the side of the connecting plate 51 away from the protective cover 41.

[0038] Working principle: When industrial waste gas is transported to the purification cylinder 1 through the transmission cylinder 11, it is first filtered through the filter screen 22 during the transmission process. The filtered waste gas then enters the purification cylinder 1 for further purification. The particles in the waste gas remain on the surface of the filter screen 22. Subsequently, the servo motor 31 and the water pump 71 are started. After the servo motor 31 starts, its output shaft drives the first gear 43 to rotate. The first gear 43 and the toothed belt 44 then drive the second gear 45 to rotate, thereby causing the second gear 45 to drive the connecting plate 51 and the cleaning brush 52 to rotate. The surface of the filter screen 22 is cleaned by rotating the connecting plate 51 and the cleaning brush 52. After the water pump 71 is started, the cleaning water in the storage tank 61 is drawn. The drawn cleaning water is transferred to the distributor 72 and then sprayed and atomized by the nozzle 73. The atomized cleaning water is sprayed on the surface of the filter screen 22. Together with the connecting plate 51 and the cleaning brush 52, the dust particles on the surface of the filter screen 22 are cleaned. The cleaned wastewater passes through the screen plate 81 and enters the conduit 82. Then it is injected into the collection tank 91 for collection and is discharged through the drain port 92 later.
