Glass fiber coated filter material with catalytic function and preparation method thereof

Abstract

The invention discloses a glass fiber coated filter material with a catalytic function and a preparation method thereof. The glass fiber coated filter material consists of a glass fiber filter material base material, a glass fiber protective film, a catalyst nano-particle layer and an expanded microporous polytetrafluoroethylene filter film. During application in filtering, dust is firstly blockedby the expanded microporous polytetrafluoroethylene filter film of the glass fiber coated filter material with the catalytic function, so that the active sites on catalyst nano-particles are prevented from being covered with the dust and thus losing activity, the catalytic function of the catalyst is efficient and can last for a long time, and residual harmful gas is decomposed by the catalyst nano-particle layer to achieve the purpose of comprehensive prevention and control of the dust and harmful gas. The integration of dust removal, desulfurization, denitration, dioxin removal, mercury removal and the like is achieved, and the filter material is particularly suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of catalytic materials, and in particular relates to a catalytic function glass fiber membrane-coated filter material and a preparation method thereof. Background technique [0002] Air pollution control has gone through or is going through the development process of dust removal, desulfurization, denitrification, dioxin removal, and mercury removal. The bag type dust removal technology is mature, and the filter material is the key component of the bag type dust collector. The glass fiber coated filter material can effectively reduce the emission of fine dust such as PM2.5, achieving 5mg / Nm 3 The following smoke and dust emissions. It is the current development direction to load the catalyst on the filter material, study the comprehensive prevention and control of dust and harmful gas by the filter material with catalytic function, and realize the integration of dust removal, desulfurization, denitrificatio...

Problems solved by technology

The method disclosed in this patent requires magnetic stirring for a certain period of time under water bath conditions when the catalyst is loaded, which is not suitable for industrial production. At the same time, in the practical application of the manganese cerium denitrification catalyst composite PPS filter material, the catalyst is easily blocked by dust and cannot maintain the catalytic performance of the catalyst. Efficient and durable
