[0033] Refer to Figure 2 , Figure 4 and Figure 5The filtering assembly comprises a second filtering plate 71 which is inserted into the inner wall of the filtering box 3, and the connection between the second filtering plate 71 and the inner wall of the filtering box 3 is sealed. The second filtering plate 71 filters the water used for cleaning the first filtering plate 4, and the water is recycled. The filtering box 3 is provided with a blowdown tank 72 on the right lower side of the second filtering plate 71. The inner wall of the blowdown tank 72 is inclined, so that the impurities can be automatically deposited at the bottom end. The lower part of the blowdown tank 72 is provided with a discharge valve, so that the collected impurities can be discharged. The filtering box 3 is provided with a limiting plate 73 at the upper part, which is used for controlling the second filtering plate 71.

The inner wall of the limiting plate 73 is provided with a through slot, so as to facilitate the operation of the operator.

[0034] Working principle: in use, the chemical gas enters the purification device through the gas inlet pipe at the lower part of the tank body 2. The conical protective cover at the upper part of the gas inlet pipe guides the flow of the entering chemical gas, changes the flow direction of the chemical gas, and makes the chemical gas enter the subsequent filtering link more uniformly. The conical protective cover effectively blocks the large-particle impurities in the chemical gas, reduces the direct impact of these impurities on the filtering components, protects the filtering device, and prevents the water used for cleaning the first filtering plate 4 from falling into the gas inlet pipe, thereby ensuring the normal gas inlet of the gas inlet pipe.

[0035] The chemical gas entering the tank body 2 first contacts the first filtering plate 4 on the inner wall of the support frame 1. The first filtering plate 4 filters the impurities in the chemical gas, intercepts part of the impurities in the chemical gas, and plays a role in preliminarily purifying the chemical gas, thereby reducing the content of pollutants in the chemical gas.

[0036] The cleaning pipe 5 at the upper part of the first filtering plate 4 starts to work under the action of the water pump. The water pump provides power for the cleaning pipe 5, so that the cleaning pipe 5 can spray water flow to clean the first filtering plate 4. Regular cleaning of the first filtering plate 4 can effectively prevent the problem of blockage caused by the accumulation of impurities, maintain the good filtering performance of the first filtering plate 4, and ensure that the purification device can continuously and efficiently operate.

[0037] The water used for cleaning the first filtering plate 4 enters the filtering box 3, and the second filtering plate 71 filters the water used for cleaning the first filtering plate 4, so that the water can be recycled, thereby improving the utilization rate of water resources. The impurities generated during the filtering process will be deposited in the blowdown tank 72 which is located at the right lower side of the second filtering plate 71. The inner wall of the blowdown tank 72 is inclined, so that the impurities can be automatically deposited at the bottom end. The lower part of the blowdown tank 72 is provided with a discharge valve, so that the collected impurities can be discharged regularly, thereby ensuring the normal operation of the filtering system.

[0038] When the activated carbon inside the device needs to be maintained and replaced, the operator rotates the crank 64, the crank 64 is threadedly connected with the threaded rod 63, rotating the crank 64 can rotate the threaded rod 63, drive the rotating rod 62 to rotate horizontally, so that the threaded rod 63 is separated from the fixed plate 65, and the fixing of the protective shell 61 is released, at this time, rotating the protective shell 61 can open the maintenance space.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
