A composite adsorption material of activated carbon fiber and metal substrate and its production method

Abstract

The invention discloses an active carbon fiber and metal substrate compounded adsorbing material and a production method thereof. The active carbon fiber and metal substrate compounded adsorbing material comprises a metal substrate, wherein any one panel / two panels of the metal substrate is / are coated with an adhesive layer(s); adsorbing material active carbon fiber felt(s) is / are pressed on the outer surfaces of the adhesive layer(s) through a compound device. As the active carbon fiber and the metal substrate compounded adsorbing material is prepared by bonding and compounding active carbon fibers and the metal substrate, and has a certain supporting strength, the adsorbing material can be used by being folded and pressed into a plurality of geometric shapes, and an adsorbing core can be directly produced by combining ventilation gaps reserved between plate materials simultaneously, so that the adsorbing area can be increased, the adsorbing efficiency is improved, the adsorbing requirements of different devices are satisfied, and the existing application method of overlaying and winding active carbon fiber felt layers is changed.

Description

technical field [0001] The invention relates to a composite adsorption material, in particular to an adsorption material composed of active carbon fibers and metal substrates. Background technique [0002] At present, the polluting organic waste gas emitted by the industry and printing industry is VOC gas, and VOC gas is volatile substances such as toluene, butanone, ethyl acetate, etc. There are more than 30,000 domestic printing and packaging enterprises, and the annual emission of VOC gas is at least 200 10,000 tons, there are very few companies equipped with purification treatment and recovery devices, which has caused serious air pollution. The printing and packaging industry has been listed as a key industry in the 12th Five-Year Plan by the state. Activated carbon fiber is an adsorption material commonly used in VOC waste gas treatment in developed countries in the world today. Activated carbon fiber has properties such as large specific surface area, strong adsorptio...

AI Technical Summary

Problems solved by technology

[0003] In the existing VOC waste gas treatment solvent recovery equipment, the adsorption medium mostly uses activated carbon fiber felt as the adsorption material, stainless steel is used as the adsorption core skeleton, and the activated carbon fiber is glued and wound with 60-120 layers as the adsorption core. The worse the performance, the greater the wind resistance. High wind resistance leads to high energy consumption

When the adsorption is saturated, it enters the regeneration process of the activated carbon fiber. The regeneration of the activated carbon fiber is usually heated by direct steam or flame retardant gas. The heating method of the adsorption core made of activated carbon fiber by two different heating media is Similarly, because the activated carbon fiber has a certain thickness and the thermal conductivity of the activated carbon fiber is extremely poor, the over-flow heating method must be used, that is, the hot gas is pressurized to pass through the adsorption material layer, so that the adsorption material can be heated to achieve regeneration. , the over-flow heating method consumes a lot of energy, the heat utilization rate is low, and the regeneration effect of activated carbon fiber is poor.
