Light and oxygen catalytic waste gas treatment system

Abstract

The invention relates to the technical field of waste gas treatment, in particular to a light and oxygen catalytic waste gas treatment system, and solves the problem of poor waste gas treatment effectof the waste gas treatment system in the prior art. The light and oxygen catalytic waste gas treatment system has the main technical scheme that the light and oxygen catalytic waste gas treatment system comprises a pretreatment device, a light and oxygen catalytic reaction device and a product collection device, wherein the light and oxygen catalytic reaction device comprises a casing and baffleplates in laminated crossing arrangement; an ultraviolet ray emitter is arranged in a position, right aligned with each baffle plate, on the casing; a reaction passage is formed between the baffle plate and the casing; sulfur dioxide and hydrogen sulfide in the waste gas are removed through the pretreatment device; the waste gas and the bacteria in the waste gas are cracked through the light and oxygen catalytic reaction device; through the product collection device, the generated carbon dioxide is collected, so that the waste gas is efficiently treated; the environment pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a photo-oxygen catalytic waste gas treatment system. Background technique [0002] As the country has paid more and more attention to environmental protection in recent years, waste gas treatment technology has developed vigorously, especially photo-oxygen catalytic waste gas treatment has made great progress. The photo-oxygen catalytic reaction is a reaction in which high-energy high-ozone UV ultraviolet light beams are used to irradiate the waste gas to be treated, so that the waste gas is cracked and oxidized. [0003] In the Chinese invention patent with the authorized announcement number CN202460470U, a photo-oxygen catalytic organic waste gas processor is disclosed, including a housing, an ultraviolet lamp and a filter medium. There is a filter medium between the outlet and the gas outlet, and the filter medium is loaded with nano-TiO 2 The active carbon fiber...

AI Technical Summary

Problems solved by technology

Due to the short contact time between exhaust gas and ultraviolet rays, the degradation time of exhaust gas is insufficient, resulting in insufficient degradation of exhaust gas, so the effect of exhaust gas treatment is poor
