Problems solved by technology
[0004] The purpose of the present invention is to solve the problem that the volatile gaseous organic pollutants usually contain some impurities with larger particles in the prior art, and it is difficult for the powder photocatalyst to fully contact with the volatile gaseous organic pollutants, resulting in low degradation efficiency. The quality is poor, and in the process of adding the powdery photocatalyst, the feeding pipe is prone to clogging, which affects the progress of the catalytic work, and a device for photocatalytic degradation of volatile organic pollutants is proposed, which can Volatile gaseous organic pollutants are preliminarily filtered to filter out the larger particulate impurities contained in them, and photocatalysts can be continuously added to the housing to fully contact with volatile gaseous organic pollutants for catalytic degradation to ensure catalytic degradation. Degradation efficiency and quality

Description
technical field [0001] The invention relates to the technical field of degradation of volatile organic pollutants, in particular to a device for photocatalytic degradation of volatile organic pollutants. Background technique [0002] Photocatalytic degradation refers to the use of radiation and photocatalysts to generate highly active free radicals in the reaction system, and then through the process of addition, substitution, electron transfer and other processes between free radicals and organic pollutants to degrade all pollutants into inorganic Most volatile organic pollutants have unpleasant special odor, and are toxic, irritating, teratogenic and carcinogenic. Therefore, photocatalytic reactions are usually used to degrade volatile gaseous organic pollutants. [0003] At present, when volatile gaseous organic pollutants are degraded by photocatalytic reactions, the volatile gaseous organic pollutants usually contain some impurities with large particles, and it is diffi...
