Problems solved by technology

The molecular sieve adsorption material made by this method is easy to fall off, the molecular sieve has low solid content and short life.
At the same time, extrusion molding is adopted, such as honeycomb body, particles, etc., although they can play an adsorption role, but the contact time between the internal adsorption material and organic waste gas is too short to achieve adsorption, and the effective utilization rate of molecular sieves is low.

Abstract

The invention relates to the technical field of VOCs adsorption and purification materials, and particularly discloses a molecular sieve-based glass fiber skeleton adsorption material as well as a preparation method and application thereof. The method for preparing the molecular sieve-based glass fiber skeleton adsorbing material comprises the following steps: providing a substrate material prepared by mixing wood pulp fibers and glass fibers and then carrying out wet molding; and enabling the surface of the substrate material to be in contact with a molecular sieve suspended emulsion, and combining suspended components in the molecular sieve suspended emulsion with the substrate material so as to obtain the molecular sieve-based wet glass fiber skeleton adsorbing material. The method is simple and convenient to operate and convenient for industrial production; and the prepared material is high in effective solid content of the molecular sieve, good in compressive strength, low in cost and excellent in adsorption performance and can be widely applied to purification treatment of industrial organic waste gas.

Description

technical field [0001] The invention relates to the technical field of VOCs adsorption and purification materials. Specifically, it relates to a molecular sieve-based glass fiber skeleton adsorption material and its preparation method and application. Background technique [0002] Industrial organic VOCs waste gas contains a large amount of volatile organic compounds such as benzene, toluene, and xylene. The continuous discharge of these substances into the atmosphere will do great harm to the human body, and is carcinogenic, teratogenic, and mutagenic. At present, the most effective way to deal with low-concentration and high-volume industrial organic waste gas is the molecular sieve runner concentration adsorption-desorption + catalytic combustion process. The core component of the molecular sieve concentration runner is the adsorption wheel core, which uses molecular sieve as the main adsorption material. Usually formed by coating onto glass fiber paper. The molecular s...
