Background

The waste gas refers to toxic and harmful gas exhausted by human in the production and living processes, and dry chemical absorption is a common method for absorbing acid-base waste gas, and the method does not need to use a liquid absorbent, but uses a dry absorbent such as activated carbon or aluminum hydroxide to absorb acid-base substances in the waste gas, and the waste gas is captured by chemical reaction on the surface of the absorbent when passing through an absorption layer, so that the effect of absorbing and purifying the waste gas is achieved;

In the process of adsorbing waste gas by using activated carbon, the waste gas is pretreated, larger-sized dust particles and impurities in the waste gas are filtered by using a filter screen, which is a common process in pretreatment, and then the filtered waste gas is adsorbed and purified by honeycomb activated carbon, wherein after the filter screen and the activated carbon are used for a long time, a large amount of dust impurities are accumulated on the filter screen, and the saturated activated carbon is adsorbed and also reaches a dangerous waste state, so the filter screen and the activated carbon on the purifying equipment are required to be replaced, and when the filter screen and the activated carbon are dismounted, the waste gas is usually stopped from being conveyed inside the purifying equipment due to the lack of the filter screen and the activated carbon for purifying and adsorbing the waste gas, so that the continuous adsorption efficiency of the waste gas is influenced;
