Photocatalytic decomposition purification system for organic waste gas

Abstract

The invention relates to the field of air purification technology, in particular to a photocatalytic decomposition purification system for organic waste gas, comprising an air inlet pipe, a dust removal pipe, a circulation pipe, a catalysis mechanism, a cleaning mechanism, a first traction mechanism, an exhaust pipe, a second traction mechanism and a spraying mechanism. The circulation pipe of a U-shaped structure can prolong the flow speed of flue gas, so that the solid particles can gather at the bottom of the circulation pipe, and obliquely distributed first and second baffles can be used for filtering out of the solid particles, thereby further improving the filtration effect; the spraying mechanism communicating with the top of the circulation pipe can accelerate the falling speed ofthe solid particles, and can cause a neutralize reaction with the flue gas to further improve the separation effect; and the first traction mechanism and the second traction mechanism can drive the cleaning mechanism to move up and down to scrape off dirt attached to the outer wall of an ultraviolet lamp, thereby ensuring the illumination intensity of the ultraviolet lamp, and improving the catalytic decomposition efficiency.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a photocatalytic organic waste gas decomposition and purification system. Background technique [0002] Photocatalytic oxidation is suitable for completely oxidizing waste odor gas into non-toxic and harmless substances at room temperature, suitable for waste gas treatment of toxic and harmful gases with high concentration, large gas volume and strong stability; photocatalytic oxidation can directly convert The waste odor gas is completely oxidized into non-toxic and harmless substances without leaving any secondary pollution. [0003] When performing photocatalytic decomposition, the photocatalytic plate needs to be used in conjunction with the UV lamp. However, after a long-term use of the UV lamp, a lot of dirt will accumulate on the outer wall of the UV lamp, which will affect the photocatalytic speed. During maintenance, it is necessary to remove the box to align th...

[0003] When performing photocatalytic decomposition, the photocatalytic plate needs to be used in conjunction with the UV lamp. However, after a long-term use of the UV lamp, a lot of dirt will accumulate on the outer wall of the UV lamp, which will affect the photocatalytic speed. During maintenance, it is necessary to remove the box to align the lamp. It is very time-consuming and laborious to clean up the body
