A filter component is provided inside the tower body 1, and the filter component can filter and adsorb particulate matter and some oily substances in the exhaust gas.

[0033] Reference Figure 2 - Figure 4 The filter assembly includes a motor 81. The motor 81 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The output shaft of the motor 81 is fixedly connected to the rotating shaft 82. Starting the motor 81 can drive the rotating shaft 82 to rotate. The inner wall of the rotating shaft 82 is elastically connected to the filter plate 84 through a compression spring 87. The lower surface of the filter plate 84 is fixedly connected to the partition 83. The partition 83 is provided with multiple groups for separating the exhaust gas entering the device to ensure that the exhaust gas rises evenly. The upper surface of the filter plate 84 is fixedly connected to a positioning block 85. The inner wall of the right side of the tower body 1 is fixedly connected to a block 86. When the positioning block 85 rotates, it will be squeezed by the block 86. The left surface of the tower body 1 is provided with a circulation assembly, which can recycle water.

[0034] Reference Figure 1 - Figure 2, the circulation component includes a water tank 91 for storing water, and a baffle 99 is fixedly connected to the inner wall of the water tank 91, which can block impurities. An injection pipe 92 is passed through and fixedly connected to the upper surface of the water tank 91, and a spray pipe 93 is provided on the right surface of the injection pipe 92. A water pump 94 is provided at the bottom end of the injection pipe 92. The water pump 94 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The water pump 94 can pump water in the water tank 91 into the injection pipe 92. A water adding pipe 95 is passed through and fixedly connected to the top of the left surface of the water tank 91. When water is insufficient, it can be added from the water adding pipe 95. A valve 1 96 is provided in the middle section of the water adding pipe 95. The valve 1 96 is used to control the switch of the water adding pipe 95. A waste pipe 97 for discharging impurities is passed through and fixedly connected to the lower surface of the water tank 91. A valve 2 98 is provided in the middle section of the waste pipe 97. The valve 2 98 is used to control the switch of the waste pipe 97.

[0035] Reference Figure 2 - Figure 4 The front end of the upper surface of the positioning block 85 is set to an inclined surface. When the inclined surface is squeezed, the positioning block 85 will move downward. The motor 81 is set on the lower surface of the tower body 1. The rotating shaft 82 passes through and is rotatably connected to the lower surface of the tower body 1. The filter plate 84 passes through and is slidably connected to the right surface of the rotating shaft 82. The filter plate 84 is concentric with the rotating shaft 82. One end of the compression spring 87 is fixedly connected to the inner wall of the bottom end of the rotating shaft 82, and the other end of the compression spring 87 is fixedly connected to the lower surface of the filter plate 84. The downward movement of the filter plate 84 will squeeze the compression spring 87 to generate a reaction force. The left surface of the filter plate 84 protrudes from the left surface of the rotating shaft 82. The upper surface of the filter plate 84 is provided with a mesh to block impurities.

[0036] Reference Figure 1 - Figure 2 The water tank 91 is fixedly connected to the bottom end of the left surface of the tower body 1, the water outlet pipe 7 passes through and is fixedly connected to the right surface of the water tank 91, and a through groove is opened on the upper surface of the baffle 99 to block impurities and prevent them from entering the injection pipe 92. Oily impurities will be soaked in water in the water tank 91, the oiliness will be weakened, and they will not adhere to the through groove on the baffle 99.

[0037] Working principle: When the device is in use, the motor 81, the water pump 94 and the demister 5 are started, and the exhaust gas entering from the smoke inlet pipe 3 will be evenly distributed in the tower body 1 under the guidance of the partition 83, and the exhaust gas will pass through the filter plate 84. When passing through the filter plate 84, the particulate impurities will be blocked by the mesh, and some oily impurities will be adsorbed at the mesh. Since the motor 81 is in the started state, it can drive the rotating shaft 82 and the filter plate 84 to rotate, and the rotating filter plate 84 will drive the positioning block 85 to rotate, and then the inclined surface of the positioning block 85 will be squeezed by the block 86, and the positioning block 85, the filter plate 84 and the partition 83 will move downward and squeeze the compression spring 87 to generate a reaction force. Under the influence of the intermittent squeezing of the positioning block 85 by the block 86 and the reaction force of the compression spring 87, the filter plate 84 will shake back and forth longitudinally, thereby being able to shake off the particulate impurities and oily impurities.

[0038] When the water pump 94 is started, the water in the water tank 91 will be pumped into the injection pipe 92 and sprinkled out from the spray pipe 93. The exhaust gas will be filtered with the cooperation of the packing layer 4 and the demister 5. The filtered exhaust gas will eventually be discharged from the exhaust pipe 6.

[0039] The water used during filtration will fall to the bottom of the inner wall of the tower body 1, and will carry particulate impurities and oily impurities into the water tank 91 through the outlet pipe 7. The used water will be pumped by the water pump 94 and enter the injection pipe 92 and the spray pipe 93 for use again. The impurities will be blocked by the baffle 99. After the exhaust gas filtration and absorption is completed, the motor 81, the water pump 94 and the demister 5 are turned off.

[0040] When there is insufficient water in the water tank 91 , valve 1 96 is opened, and water is added to the water tank 91 from the water adding pipe 95 . When impurities in the water tank 91 need to be cleaned, valve 2 98 is opened to discharge the impurities from the waste pipe 97 .

[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.
