In-situ regenerable adsorption photocatalysis and ozone synergistic purification method and device for VOCs

Abstract

The invention relates to an in-situ regenerable adsorption photocatalysis and ozone synergistic purification method and device for VOCs. The device comprises annularly-distributed ultraviolet lamp tubes and heating lamp tubes arranged in the device, the periphery of the ultraviolet lamp tubes and the heating lamp tubes is corona generation electrode electric purifying wires, and the corona generation electrode electric purifying wires are wound by a wire holder assembled in an annular installation frame to form annular arrangement; an activated carbon fiber adsorption layer loading with a photocatalyst, an ozone catalyst layer and a dust collecting electrode are sequentially arranged at the outer side of the corona generation electrode electric purifying wires, the activated carbon fiber adsorption layer, the ozone catalyst layer and the dust collecting electrode are attached together to form a barrel structure, and the outermost-layer outer-side dust collecting electrode forms a device skeleton and has a metal mesh structure. After the technical solution provided by the invention is adopted, the VOCs can be effectively removed, the purification efficiency is higher, at the same time, decomposition products of the VOCs can be effectively desorbed, and the purification efficiency can be restored in time.

Description

technical field [0001] The invention relates to the field of industrial waste gas purification, in particular to an in-situ regenerable VOCs adsorption photocatalysis and ozone synergistic purification method and device. Background technique [0002] According to the research results of the China Academy of Environmental Planning, the annual emission of VOCs is about 31 million tons, and the potential of VOCs emission reduction is huge. VOCs treatment has also gradually received attention and made some progress. Various provinces and cities have introduced corresponding measures and regulations according to the local industrial structure and VOCs pollution situation; ideal. As more and more stringent industry standards and local standards are gradually formulated, enterprises or universities with low-concentration and large-volume VOCs emission characteristics will also carry out engineering construction and transformation in accordance with corresponding regulations. The m...
