Waste gas adsorption and impurity removal device

The utility model relates to the technical field of waste gas treatment, in particular to a waste gas adsorption and impurity removal device which comprises a box body, a filter screen frame, a filtrate chamber, a liquid mixing mechanism and a spraying mechanism, the filter screen frame is fixedly connected into the box body, the filtrate chamber is arranged between the filter screen frame and the inner bottom end of the box body, and the liquid mixing mechanism is communicated to the filtrate chamber. And the box body is connected with a spraying mechanism for waste gas treatment. The spray liquid flowing downwards is filtered by the filter screen frame and then gathered in the filtrate chamber, precipitates in the spray liquid are reduced, so that the spray head cannot be blocked, the spray liquid in the filtrate chamber is driven to flow after the liquid mixing mechanism is electrified and started, and the flowing spray liquid collides with the filter screen frame, so that the precipitates on the filter sc
