Abstract

The invention provides a laboratory waste gas treatment device. The device comprises: a box body, wherein a cavity is formed in the box body, the box body comprises a gas inlet and a gas outlet, and the gas inlet is located below the gas outlet; a filtering assembly positioned in the cavity of the box body; and a desorption assembly fixedly connected with the inner wall of the box body, and located above the filtering assembly. According to the invention, a dust removal assembly is arranged before gas containing organic matters generated in a laboratory is absorbed by activated carbon, so that the activated carbon is effectively prevented from being blocked by dust particles, and the absorption effect is not influenced; and the desorption mechanism can automatically peel off the dust according to the content of the dust, and meanwhile, the desorption mechanism is matched with the heating mechanism to desorb and recycle the activated carbon, so that the production cost is effectively saved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a laboratory waste gas treatment device. Background technique [0002] At present, the toxic and harmful gases produced in the existing laboratory tests are discharged into the atmosphere through fume hoods, fume hoods or ventilation fans, causing environmental pollution. Some experimental adsorption equipment cannot be placed in the fume hood, which makes it difficult to discharge harmful gases. These If the exhaust gas is discharged directly, it will cause harm and serious pollution to the staff and the external environment, and most of the laboratories are closed environments, so the potential danger is even more serious. The composition of laboratory exhaust gas is relatively complex, and the laboratory exhaust gas has the characteristics of discontinuous discharge. Therefore, the absorption method is generally used for the treatment of laboratory exhaust gas...
