The harmful substances contained in waste gas, such as volatile organic compounds (VOCs), particulate matter, sulfides, etc., pose a huge threat to the environment and human health. Among the many waste gas treatment technologies, activated carbon catalytic waste gas purification has attracted widespread attention due to its advantages such as high efficiency, economy and wide applicability.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment of an activated carbon catalytic exhaust gas purification device, comprising a box body 1, an exhaust hole is provided at the top of the box body 1, an air inlet is provided on the left side, and a water tank for filtering water is provided on the right side for activated carbon catalytic purification of exhaust gas. It is a prior art, so it will not be described in detail in this case. An activated carbon plate 2 is provided on the upper inner wall of the box body 1, which utilizes the adsorption characteristics of the activated carbon micropores to adsorb organic matter in the exhaust gas. A sealing door is provided near the front end of the box body 1 near the activated carbon plate 2 for easy replacement of the activated carbon plate 2. A filter screen 3 is provided near the bottom end of the box body 1 near the activated carbon plate 2 to further filter the exhaust gas entering the box body 1 and remove larger impurities and particulate matter. An installation platform is provided on the left side of the box body 1 for installing a drive motor 4 and related cleaning components. A drive motor 4 is provided at the bottom end of the installation platform to provide power for the cleaning component to drive the turntable 51 to rotate.

[0033] Furthermore, the output shaft of the drive motor 4 passes through the mounting platform, and the top end of the output shaft of the drive motor 4 is fixedly connected to a cleaning component, which includes a turntable 51. The bottom end of the turntable 51 is fixedly connected to the top end of the output shaft of the drive motor 4. A connecting column is fixedly connected to the top end of the turntable 51 deviating from the center of the circle. The connecting column at the top end of the turntable 51 deviating from the center of the circle can drive the swing rod 52 to swing. The outer wall of the connecting column is slidingly connected to the swing rod 52. The bottom end of the rear side of the swing rod 52 is rotatably connected to the top end of the mounting platform. The rear arc surface of the swing rod 52 is provided with teeth, which slides on the inner wall of the swing rod 52 through the connecting column, so that the teeth on the rear arc surface are used to drive the rack 53 to move back and forth left and right.

[0034] Reference Figure 2 - Figure 4 The rack 53 is meshed with the teeth of the swing rod 52 on the rear side, and is driven by the rack 53 to make a reciprocating linear motion. The inner wall of the rear side of the rack 53 is slidably connected to the limit block 54, which guides and limits the movement of the rack 53, so that the rack 53 can only move in a specific direction. The bottom end of the limit block 54 is fixedly connected to the top of the mounting platform. A mounting plate 55 is provided on the right side of the limit block 54 near the inside of the box 1 for installing a cleaning plate 56. There are multiple groups of mounting plates 55, and the multiple groups of mounting plates 55 are equidistantly arranged. By setting multiple groups, the filter screen 3 can be fully cleaned with a small movement, thereby improving the cleaning efficiency.

[0035] Furthermore, the inner walls of the upper and lower ends of the mounting plate 55 are slidably connected with a cleaning plate 56, and a brush is provided on the side of the cleaning plate 56 away from the mounting plate 55 for cleaning the bottom end of the filter 3 and the top end of the spray plate 61 to prevent impurities cleaned from the filter 3 from falling onto the top end of the spray plate 61. The cleaning plate 56 and the mounting plate 55 are elastically connected by a compression spring 57. The elastic force of the compression spring 57 ensures that the brush on the cleaning plate 56 is always in close contact with the bottom end of the filter 3 and the top end of the spray plate 61, thereby improving the cleaning efficiency and ensuring the smooth circulation of the exhaust gas, thereby improving the overall purification effect. The inner walls of the front and rear sides of the mounting plate 55 are both penetrated by a stabilizing rod 58 for slidably connecting to improve the stability of multiple groups of mounting plates 55 when moving. The left and right ends of the stabilizing rod 58 are fixedly connected to the inner wall of the box body 1.

[0036] Reference Figure 2 and Figure 5 A spray assembly is provided on the inner wall of the box body 1 near the bottom of the lower cleaning plate 56. The spray assembly includes a spray plate 61, which can block and divert the exhaust gas. The outer side of the spray plate 61 is fixedly connected to the inner wall of the box body 1. A through hole 62 is opened through the inner wall of the top of the spray plate 61. There are multiple groups of through holes 62 for allowing the exhaust gas to pass through. A delivery pipe 63 is provided on the right side of the spray plate 61 for delivering liquid. A water pump is provided on the right side of the delivery pipe 63 for extracting the filtered water in the water tank for reuse.

[0037] Furthermore, a spray head 65 is provided on the inner wall of the spray plate 61 near the lower side of the through hole 62, and a through groove 64 is opened on the inner wall of the spray plate 61, and the through groove 64 is connected with the delivery pipe 63. The through groove 64 is connected with the delivery pipe 63 and the inside of the spray head 65, so that the liquid can be sprayed out from the spray head 65. The through groove 64 is connected with the inside of the spray head 65. The spray head 65 is annular, and the bottom side of the nozzle on the spray head 65 is inclined toward the center of the through hole 62, so that the liquid is sprayed more evenly, the particulate matter in the exhaust gas is effectively settled, and the influence of the particulate matter on the activated carbon catalysis is reduced, thereby improving the catalytic effect of the activated carbon.

[0038] Working principle: When in use, the drive motor 4 is started, and its output shaft drives the turntable 51 to rotate. When the connecting column at the top of the turntable 51 deviates from the center of the circle rotates, it drives the swing rod 52 to swing. Since the teeth on the arc surface on the rear side of the swing rod 52 engage with the rack 53, the rack 53 makes a reciprocating linear motion left and right under the restriction of the limit block 54.

[0039] The reciprocating motion of the rack 53 drives the mounting plate 55 to move. The cleaning plate 56, which is slidably connected to the inner walls of the upper and lower ends of the mounting plate 55, is acted upon by the compression spring 57 so that the brush on the cleaning plate 56 always clings to the bottom end of the filter 3 and the top end of the spray plate 61. As the mounting plate 55 slides on the outer wall of the stabilizing rod 58, the cleaning plate 56 cleans the filter 3 and the spray plate 61, thereby ensuring smooth flow of exhaust gas and improving the overall purification effect.

[0040] At the same time, the water pump delivers the liquid to the through groove 64 of the spray plate 61 through the delivery pipe 63, and then sprays it out from the annular spray head 65. The bottom side of the nozzle of the spray head 65 is inclined toward the center of the through hole 62, which can spray the liquid more evenly onto the spray plate 61, effectively settle the particulate matter in the exhaust gas, reduce the impact of the particulate matter on the activated carbon catalysis, and thus improve the catalytic effect of the activated carbon.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
