Problems solved by technology

[0004] In the prior art, fibers containing catalysts are used to undergo a series of processing processes such as opening, mixing, and carding with other synthetic fibers. Due to their low strength, the fibers containing catalysts cannot withstand the strong opening force in this process.
After such processing, it will cause damage and breakage of the fiber containing the catalyst, resulting in a reduction in end-use performance

Abstract

The invention relates to a filter material integrating dust removal and dioxin decomposition and a preparation method thereof. The filter material comprises a supporting catalyst layer, a base cloth layer and a supporting layer. One side of the base cloth layer is arranged at one side of the supporting catalyst layer, and the other side of the base cloth layer is arranged on the supporting layer; the supporting catalyst layer is formed by stacking and covering a catalyst layer on the catalytic supporting layer. The preparation method is as follows: stacking, needling and post treatment, and the like, are carried on a polytetrafluoroethylene microporous membrane with a dioxin decomposition catalyst, a high temperature resistant fiber supporting layer and the base cloth layer to obtain the filter material. The preparation method has the advantages of simple and practical process, low machining cost and little fiber damage. The filter material can be widely used for dust removal and dioxin decomposition in high-temperature tail gas.

Description

technical field [0001] The invention relates to a filter material, in particular to an integrated filter material for dust removal and dioxin decomposition and a preparation method thereof. Background technique [0002] With the rapid development of modern industrialization in various countries in the world, air pollution has become an increasingly serious global problem, and countries all over the world attach great importance to the emission of dioxins. Activated carbon adsorption is a common method for treating dioxins at home and abroad. Although it has a good removal efficiency, it will reach adsorption saturation if activated carbon is used for a long time. Activated carbon with saturated adsorption is often landfilled. This method actually only transfers the gaseous dioxins to the solid phase. After landfilling, it is very likely to cause secondary pollution to soil and groundwater sources. In recent years, catalyst oxidation decomposition technology has been paid mo...
