Pharmaceutical waste gas treatment device

The invention relates to the field of air dust removal, in particular to a pharmaceutical waste gas treatment device. Comprising a tank body, and a rotating shaft, blades, screen cloth, a supporting ring and an electric motor which are positioned in the tank body, the rotating shaft rotates relative to the tank body, the blades are fixedly connected with the rotating shaft through a turntable, the blades are fixed on the inner side of the supporting ring, the screen cloth is fixed in an area surrounded by the supporting ring, the blades and the turntable, an upper partition plate is fixedly connected in the tank body, and water is filled above the upper partition plate; when the dust collector is used, water flows downwards to the mesh cloth, the blades drive external airflow to penetrate through the mesh cloth from top to bottom and collide with the wetted mesh cloth at the same time, so that dust in the air is adsorbed, and the dust adhering to the mesh cloth is automatically washed away under the gravity a
