Abstract

The invention relates to an integrated multi-medium-catalysis waste gas treatment device, comprising an oxidation reaction tank, a photocatalyst recovery system, a circulating spraying system, an absorption reactor, a dosing system, an ozone generation system and a UV catalytic system, wherein the absorption reactor comprises a filler distribution layer and a catalytic ozonation bed layer. The invention also discloses an application method of the device. The application method comprises the following steps: adding hydrogen peroxide or sodium hypochlorite into the oxidation reaction tank via the dosing system; allowing waste gas to enter the absorption reactor through an inlet and to be mixed with ozone generated by the ozone generation system; atomizing oxidation absorption liquid via thecirculating spraying system, and allowing the oxidation absorption liquid to pass through the filler distribution layer and the catalytic ozonation bed layer for purification and then to be dischargedfrom an outlet; and turning on the UV catalytic system, enabling the treated oxidation liquid to overflow to the photocatalyst recovery system, pumping a recovered photocatalyst to the oxidation reaction tank, and spraying a supernatant into the absorption reactor through the circulating spraying system. The device disclosed by the invention is simple in structure and easy to operate, and can improve the problems of low treatment efficiency and serious secondary pollution at present.

Description

technical field [0001] The invention relates to an exhaust gas treatment device, in particular to an integrated multi-media catalytic exhaust gas treatment device. Background technique [0002] The increase in air pollutant emissions is the main reason for the decline in air quality. Volatile organic compounds (VOCs) play a very important role in the photochemical process of the atmosphere, affecting the oxidation of the atmosphere, the formation of secondary aerosols, and atmospheric radiation. , has a significant impact on the global climate environment. [0003] Volatile organic compounds are a general term for a class of organic compounds. They have a high evaporation rate at room temperature and are easily volatile, which is the main cause of air pollution. Typical VOCs include benzenes, esters, alcohols, ketones and aldehydes, etc. VOCs are also toxic, teratogenic and carcinogenic, and seriously endanger human health. [0004] Absorption method is one of the common ...
