Air filtering material

Abstract

The invention provides an air filtering material, which comprises a base material and a compound layer, wherein the base material consists of an upper layer of carbon fiber reticular filtering cloth and a lower layer of carbon fiber reticular filtering cloth; the compound layer is positioned between the upper layer of carbon fiber reticular filtering cloth and the lower layer of carbon fiber reticular filtering cloth and comprises a kieselguhr loaded titanium dioxide layer and a carbon material adsorption layer from top to bottom in sequence. In the air filtering material, the kieselguhr loaded titanium dioxide layer and the carbon material adsorption layer are taken as main adsorption layers so as to effectively combine physical adsorption with chemical adsorption. While small particles are filtered, volatile organic compounds can be degraded into poisonless and harmless CO2 and H2O as well as corresponding inorganic ions, and therefore, the air filtering material has the advantages of no secondary pollution, high adsorption function, obvious filtering effect and wide popularization function.

Description

technical field [0001] The invention relates to the field of materials, in particular to an air filter material. Background technique [0002] In recent years, the technical performance requirements of purification engineering and purification equipment for filter materials have gradually developed towards energy-saving and low-consumption type, the requirements for environment and air purification are getting higher and higher, and the requirements for various performance indicators of air purification materials are also getting higher . The existing bag filter dust bag filter cloth is composed of three layers, that is, it is composed of the surface layer, the middle layer and the bottom layer. The bottom layer of the dust bag filter cloth is a filter cloth made of various fiber materials, mainly Polypropylene fiber, polypropylene filter cloth, polyester filter cloth, brocade. Polypropylene filter cloth and non-woven filter cloth, among which PP non-woven filter cloth mad...

Problems solved by technology

[0003] However, in the prior art, most of the air quality is purified by physical adsorption, and the purification of toxic, harmful and odorous gases and the air purification methods of low concentration and tiny particles and air filter materials are limited. Therefore, it is necessary to develop a high-efficiency Practical air purification materials that can purify toxic and harmful chemical gases are very necessary
