Abstract

The invention belongs to production equipment of filter materials, and particularly relates to production equipment, a production system and a production process of a glass fiber composite filter material. The production equipment of the glass fiber composite filter material comprises a headbox provided with a slurry inlet and a slurry outlet, a forming net communicated with the slurry outlet, a driving mechanism used for driving the forming net to circularly pass through the slurry outlet, a first unwinding roller used for conveying a protective layer between the headbox and the forming net, and a first dehydration device communicated with the slurry outlet through the forming net. Through the production equipment, the double-layer glass fiber composite filter material can be formed without adding a hot melt adhesive, and the double-layer glass fiber composite filter material has higher tensile strength, so that on the basis of ensuring higher tensile strength, the filtering resistance and the pressure drop of the filter material are obviously reduced, the air permeability of the glass fiber filter material is improved, then the service life is facilitated to be prolonged, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to production equipment of filter materials, and in particular relates to production equipment, a production system and a production process of glass fiber composite filter materials. Background technique [0002] With the development of society and the improvement of people's living standards, people's requirements for environmental quality are getting higher and higher. Countries all over the world pay more and more attention to the development and application of dust removal technology and equipment. At present, dust removal devices mostly use bag filter and electrostatic precipitator. The key of bag filter is filter material. Glass fiber filter material is widely used because of its high temperature resistance, corrosion resistance, smooth surface, dust peeling and good dimensional stability. It is used in air and liquid filtration in many fields. The production process of glass fiber filter material is similar to that of spe...
