Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a circulating waste gas treatment device. Background Art

[0002] Waste gas refers to the toxic and harmful gases discharged by humans during the production and life processes.

[0003] The structure of the exhaust gas treatment device can refer to the utility model disclosed in the authorization announcement number "CN 218107289U", which discloses "a circulating exhaust gas treatment device". By setting a circulation mechanism in conjunction with a filtering mechanism, the reaction agent water is recycled and the exhaust gas is filtered twice, so that the exhaust gas filtration is more thorough and no secondary pollution is generated. The card slot is set in conjunction with the pull rod, so that the filter plate can be easily pulled out of the water flow frame, which is convenient for removing the filter plate, cleaning and replacing the filter plate. The existing exhaust gas treatment device usually has catalytic oxidation, chemical reaction and activated carbon adsorption methods for treating exhaust gas. The chemical reaction method is to filter and treat the exhaust gas by reacting the reaction agent, but the reaction agent needs to be added all the time, which easily leads to waste of resources. The exhaust gas treatment device has poor filtering effect and the gas discharged into the air will cause secondary pollution.

[0004] However, when the activated carbon plate in the above device is non-detachable, the adsorption efficiency of the activated carbon will be reduced after the activated carbon plate has been used for a period of time, which may easily lead to a reduction in the effect of exhaust gas treatment.
