Problems solved by technology

However, the current processing device is mainly a microwave module for microwave-driven ultraviolet lamps. It mainly uses metal materials to form a cavity that closes the microwave electromagnetic field. There is an ultraviolet lamp in the cavity, and the microwave field energy is radiated into the cavity through the microwave device to perform photocatalysis. , the efficiency of this microwave module to deal with VOCs is low, and its life is short

Abstract

The invention provides an organic waste gas photo-catalytic oxidation device and belongs to the field of organic waste gas treatment equipment. The device comprises a shell and a microwave generator,wherein a gas inlet and a gas outlet are formed in the shell; the microwave generator is used for forming a microwave electromagnetic field inside the shell; catalyst net plates are arranged on both the gas inlet and the gas outlet of the shell; and an ultraviolet lamp tube and a photocatalyst plate are arranged inside the shell. With the combination of three techniques of microwaves, ultravioletlight and photocatalysts, VOC (Volatile Organic Compound) molecules can be efficiently catalyzed and oxidized, a hydroxyl photo-catalytic oxidation effect achieved after the photocatalyst is radiatedwith ultraviolet light is better than a conventional ultraviolet light photolysis effect, the VOC treatment efficiency is improved by twice or greater, and the service life is effectively prolonged by5 times.

Description

technical field [0001] The invention relates to the field of organic waste gas treatment equipment, in particular to a photocatalytic oxidation device for organic waste gas. Background technique [0002] At present, the treatment of organic waste gas generally adopts ultraviolet photocatalytic oxidation technology. Specifically, it is directly connected to the waste gas collection device. Under ultraviolet irradiation, benzene, toluene, xylene, non-methane total hydrocarbons, TVOC, etc. Degraded substances are removed. However, the current processing device is mainly a microwave module for microwave-driven ultraviolet lamps. It mainly forms a cavity with a closed microwave electromagnetic field through metal materials. There is an ultraviolet lamp in the cavity, and the microwave field energy is radiated into the cavity by the microwave device to perform photocatalysis. , this microwave module has low efficiency in processing VOCs and has a short lifespan.
