Abstract

The invention discloses a purification device for industrial waste gases, and relates to the field of waste gas purification equipment, the purification device includes a waste gas main pipeline, the waste gas main pipeline is provided with an exhaust fan, one end of the waste gas main pipeline is connected with a water screen cabinet located in a spraying workshop, the other end of the waste gas main pipeline is connected with a circulating absorption tower, the circulating absorption tower is sequentially connected with an activated carbon adsorber and a strengthening adsorber by a pipeline A, the strengthening adsorber comprises a casing, two ends of the casing are respectively provided with a gas inlet and a gas outlet, the casing is internally detachably in turn provided with a coarse filter cotton layer, a HEPA filter layer, a photocatalytic filter plate and a nano photocatalytic filter plate, and the coarse filter cotton layer is close to the gas inlet. The purification device is simple in structure, after absorption and filtering by the heavy water curtain cabinet, the circulation absorption tower and the activated carbon adsorber, large and small dust particles in the waste gases are basically sedimentated, and volatile organic compounds and odor gases are absorbed by the strengthening adsorber so as to achieve the advantage of up-to-standard emission.

Description

technical field [0001] The invention relates to the field of waste gas purification equipment, and more specifically relates to a purification equipment for industrial waste gas. Background technique [0002] Industrial waste gas refers to the general term for all kinds of pollutant gases that are discharged into the air during fuel combustion and production processes in the factory area. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid mist lead mercury, beryllium compounds, smoke and productive dust, which will pollute the air when discharged into the atmosphere. These substances enter the human body through the respiratory tract in different ways, some directly cause harm, and some have a cumulative effect, which will seriously endanger human health. Different substances will have different effects. [0003] Therefore, industrial waste gas cannot be dir...
