The impurities in the water and some particulate impurities have a dust reduction effect and preliminarily filter the exhaust gas. The upper surface of the absorption box 1 is penetrated and fixedly connected with an air delivery pipe 5. The middle section of the air delivery pipe 5 is provided with a fan 6. The fan 6 is a prior art and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The fan 6 can draw the air inside the absorption box 1 along the air delivery pipe 5 and transport it into the filter box 7. The outer wall of the right end of the air delivery pipe 5 is fixedly connected with the filter box 7. The interior of the filter box 7 is provided with a filter component. The component can further filter the exhaust gas. The filter component includes an activated carbon plate 81. The activated carbon plate 81 can have the functions of adsorption and filtering. It can adsorb the miscellaneous odors in the exhaust gas to ensure that the discharged air will not affect the environment. The front surface of the filter box 7 is penetrated and slidably connected with a pull plate 82. The inner wall of the front side of the pull plate 82 is fixedly connected with a positioning ring 811. The positioning ring 811 is fixed at the lower position of the inner wall of the front side of the pull plate 82. The positioning ring 811 is elastically connected to the filter plate 83 through a compression spring 89. The upper surface of the filter plate 83 is provided with a mesh. The mesh has a small aperture and can isolate impurities in the exhaust gas.

By squeezing the inclined surface of the positioning block 88, the positioning block 88 will drive the filter plate 83 to move downward. The inner wall of the bottom end of the absorption box 1 is set as an inclined shape, and the sewage inside the absorption box 1 can flow out of the absorption box 1 from the outlet pipe 3 along the inclined surface.

Starting the motor 85 can drive the rotating shaft 86 to rotate. The lower surface of the rotating shaft 86 is fixedly connected to a positioning plate 87.

[0036] Reference Figure 1 - Figure 2 The dust reduction component includes a water tank 41, and a water pump 42 is arranged on the upper surface of the water tank 41. Starting the water pump 42 can pump out the water in the water tank 41.

[0037] Reference Figure 1 - Figure 2 The rear surface of the water tank 41 is fixedly connected to the front surface of the absorption box 1.

[0038] Reference Figure 1 , Figure 4 , Figure 5 The adjustment component includes a threaded rod 91, the thread lead angle on the threaded rod 91 is less than 5 degrees, and it has self-locking properties. The rear surface of the threaded rod 91 is rotatably connected to a round block 92, and the threaded rod 91 can drive the round block 92 to move forward and backward when it rotates. The left surface of the positioning block 88 is fixedly connected to a sliding rod 93, and the right surface of the round block 92 is provided with a sliding groove 901, and the sliding groove 901 is set to be inclined.

[0039] Reference Figure 1 , Figure 4 , Figure 5 The threaded rod 91 penetrates and is threadedly connected to the front surface of the filter plate 83, the round block 92 is slidably connected to the inner wall of the filter plate 83, and slides in the front-to-back direction. The sliding rod 93 is slidably connected to the inner wall of the slide groove 901. When the round block 92 moves back and forth, the position of the slide groove 901 will be changed. When the slide groove 901 moves, it will squeeze the sliding rod 93 to make the sliding rod 93 move longitudinally.

[0040] Working principle: When the device is used, first start the water pump 42 and the fan 6, and the exhaust gas will enter the absorption box 1 from the air inlet pipe 2. The started water pump 42 will pump out the water inside the water tank 41 and pump the water into the connecting pipe 43 and finally spray it out from the nozzle 44. The water sprayed from the nozzle 44 will mix with the exhaust gas. The water will absorb the impurities and some particulate matter that are easily soluble in water in the exhaust gas, and drive these impurities to sink to the bottom of the absorption box 1, and be discharged from the water outlet pipe 3 along the inclined surface at the bottom end of the inner wall of the absorption box 1.

[0041] When the fan 6 is started, the exhaust gas in the absorption box 1 will be sucked into the air duct 5 and discharged into the filter box 7 along the trajectory of the air duct 5. The exhaust gas entering the filter box 7 will continue to move upward under the push of wind and will eventually be discharged from the outlet pipe 10. The exhaust gas inside the filter box 7 will pass through the activated carbon plate 81 and the filter plate 83 when moving upward. The exhaust gas passing through the activated carbon plate 81 and the filter plate 83 will be filtered again to ensure that the gas discharged from the outlet pipe 10 is clean and will not affect the environment.

[0042] However, since the exhaust gas passing through the filter plate 83 has passed through water mist in the previous step, it is relatively humid. When passing through the filter plate 83, humid impurities are easily accumulated in the mesh holes on the filter plate 83. Over time, the mesh holes are easily blocked, affecting air circulation, which will affect the filtering effect. For this reason, the motor 85 can be started to drive the rotating shaft 86 and the positioning plate 87 to rotate. The rotating positioning plate 87 will squeeze the inclined surface of the positioning block 88. When the inclined surface of the positioning block 88 is squeezed, the filter plate 83 will be driven to move downward to squeeze the compression spring 89 to generate a reaction force. When the positioning plate 87 is rotated to disengage from the positioning block 88, the reaction force of the compression spring 89 will drive the filter plate 83 to perform longitudinal elastic movement to shake off the impurities. The impurities shaken off are piled up together, so they are heavy and will fall downward into the dust collecting plate 11, which is convenient for subsequent centralized processing.

[0043] Furthermore, if it is necessary to adjust the shaking amplitude of the filter plate 83, the threaded rod 91 can be rotated to drive the round block 92 to move forward and backward. When the round block 92 moves, it will drive the slide groove 901 to move and squeeze the slide rod 93. Since the slide groove 901 is inclined, the slide rod 93 will move longitudinally and drive the positioning block 88 to move longitudinally, thereby changing the area of ​​the inclined surface leaked by the positioning block 88, thereby changing the area of ​​the inclined surface of the positioning block 88 squeezed by the positioning plate 87, thereby adjusting the shaking amplitude. When the exhaust gas is filtered, the activated carbon plate 81, the pull plate 82, and the dust collecting plate 11 can be pulled out to clean up the excess impurities.

[0044] 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 substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
