Pretreatment device of organic waste gas and use method of pretreatment device

Abstract

The invention discloses a pretreatment device of organic waste gas and a use method of the pretreatment device. The pretreatment device comprises a cooling and deodorizing tower and a three-level dust chamber, wherein the cooling and deodorizing tower comprises a primary cooling chamber and a secondary deodorizing room, the primary cooling chamber comprises a hot gas inlet, a plurality of layers of spraying rooms and a wet gas outlet, the secondary deodorizing room comprises an odourless gas outlet, a deodorizing room spray head, a packing layer, a water collecting box and a wet gas inlet in sequence from top to bottom, the three-level dust chamber comprises a plurality of cyclone separators, and each cyclone separator comprises a shell, an odourless gas inlet, a lower hopper and a dustless gas outlet. According to the device provided by the invention, cooling, deodorizing and dust collection are orderly combined, the plurality of layers of spraying rooms can be used for guaranteeing that gas is sufficiently cooled, prewetting treatment is carried out for the further deodorizing process while cooling is carried out, and all used water is circulating water, so that the concept of economization and environmental protection is met.

Description

technical field [0001] The invention belongs to the field of waste gas treatment, and in particular relates to a pretreatment device for organic waste gas and a use method thereof. Background technique [0002] With the continuous development of my country's economy, a large number of chemical companies have emerged. These companies emit a large amount of industrial organic waste gas every year, which has a serious impact on the atmospheric environment. Therefore, the treatment of industrial organic waste gas has become the top priority in environmental governance. In recent years, scientific researchers have carried out a lot of research work on the treatment technology of organic waste gas, and these research results have been gradually industrialized, making many organic waste gas treatment technologies and treatment facilities available on the market. Organic waste gas treatment refers to the treatment work of adsorption, filtration and purification of organic waste gas...
