A low-concentration sulfide exhaust gas combined purification device

Abstract

The invention belongs to the field of technologies for treating low-concentration vulcanization waste gas, and particularly relates to a combined type purification device for low-concentration vulcanization waste gas. The combined type purification device comprises a photolysis oxidation equipment body and waste gas purification spraying equipment. The waste gas purification spraying equipment is divided into a left portion and a right portion, flow guide plates are arranged between the photolysis oxidation equipment body and the left portion of the waste gas purification spraying equipment, a primary spraying component is arranged on the top of the left side of the waste gas purification spraying equipment, and secondary spraying components are arranged on the right side of the waste gas purification spraying equipment; a cooling circulating water tank is arranged at the bottom of the waste gas purification spraying equipment, the primary spraying component and the secondary spraying components are sequentially connected with a circulating water pump and the cooling circulating water tank by a spraying pipe, a demister is arranged on the top of the waste gas purification spraying equipment, and a waste gas outlet is sequentially formed in the top of the waste gas purification spraying equipment. The combined type purification device for the low-concentration vulcanization waste gas has the advantages that the combined type purification device is stable in work performance and convenient to maintain, and a large quantity of low-concentration vulcanization waste gas generated in rubber product vulcanization procedures can be thoroughly and effectively treated by the aid of the combined type purification device.

Description

technical field [0001] The invention relates to a combined purification device for low-concentration sulfurized waste gas, which belongs to the technical field of low-concentration sulfurized waste gas treatment. Background technique [0002] Because rubber has excellent properties such as light weight, low price, high strength and easy processing, it has been widely used in production and life. Except for a very small number of plastic pipes and plates, 90% of rubber products have a short service life, resulting in a sharp increase in the amount of rubber. The chemical composition of the low-concentration vulcanized waste gas in the rubber industry tires and rubber products is particularly complex. The waste gas components include: sulfur dioxide, nitrogen oxides, ammonia, non-methane total hydrocarbons, styrene, hydrogen sulfide, TVOC, odor Gas concentration, trimethylamine, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide. Moreover, during the rubb...
