Long-diameter micro-optic resonance waste gas treatment device

Abstract

The invention discloses a long-diameter micro-optic resonance waste gas treatment device. The long-diameter micro-optic resonance waste gas treatment device comprises a shell, a gas inlet pipe and a gas outlet pipe, wherein the shell is internally provided with an ultraviolet assembly and a photocatalyst assembly; the ultraviolet assembly comprises a lamp holder and an ultraviolet lamp tube; the photocatalyst assembly comprises a plate frame and a photocatalyst plate; the photocatalyst plate is a ventilated screen plate; the plate frame and the lamp holder are of gas-impermeable plate-shaped structures; the lamp holder and the plate frame are arranged in the shell in a staggered manner; an S-shaped gas flow channel is formed between the lamp holder and the plate frame; the photocatalyst plate is obliquely arranged in the gas flow channel; two ends of the photocatalyst plate are in sealed connection with the lamp holder and the plate frame; and a far light end face is opposite to the ultraviolet lamp tube. According to the long-diameter micro-optic resonance waste gas treatment device, the photocatalyst plate is obliquely arranged in the channel where waste gas passes through in the staggered manner; while the ultraviolet lamp tube is used for sufficiently illuminating the photocatalyst plate, the waste gas brings away ozone and hydroxyl, which are generated at two sides of the photocatalyst plate, through the photocatalyst plate, so that the waste gas is sufficiently purified; and the lamp holder and the plate frame are arranged in the staggered manner, so that a waste gas purification path is prolonged and the waste gas is purified more completely.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, in particular to a long-diameter low-light resonant waste gas treatment device. Background technique [0002] With the current development of industry and commerce and the enhancement of environmental protection awareness, the deteriorating living environment has attracted the general attention of the public and the industry. Among them, due to the vigorous development of industry, air pollution spreads rapidly, and harmful exhaust gas spreads over a large area. The pollutants directly harm people's health through the respiratory system. In response to this development trend, various technologies and equipment related to environmental protection engineering have been continuously developed. The purification treatment of industrial waste gas is one of the most important issues faced in many environmental protection cases. [0003] At present, the industry mainly adopts activated carbo...

AI Technical Summary

Problems solved by technology

[0008] 1. Since the ultraviolet rays irradiated by the lamp tube are diffusive, and the photocatalyst plate is a planar structure, the middle part of the photocatalyst plate is close to the lamp tube, and its edge is far away from the lamp tube, so the light intensity obtained in the middle part is much greater than that in the edge part, resulting in the photocatalyst plate The air purification capacity of the central part is much larger than that of the edge part, and the distribution is uneven

[0009] 2. The exhaust gas flows along one side of the photocatalyst plate, so that the concentration of ozone and hydroxyl on one side of the photocatalyst plate is lower than that on the other side, resulting in low purification efficiency
