Abstract

The invention relates to a multilayer fiber composite filter material.The multilayer fiber composite filter material is sequentially provided with an inner supporting layer, a polypropylene superfine fiber layer, a fine fiber glass fiber layer, a crude fiber glass fiber layer and an outer supporting layer from inside to outside.According to the multilayer fiber composite filter material, fiber filter layers of multiple dimensions and mesh numbers are composited together from outside to inside from coarse filtering to fine filtering, so that the filtering capacity of the filter material is distributed in gradient, particles of different dimensions are effectively intercepted in a segmented mode, it can be avoided that a filter screen small in mesh is used for filtering large-particle matter, and consequently a filter material is wasted, the use cost of the filter material is reduced, the filter efficiency of the filter material is improved, the service life of the filter material is prolonged, and the pollution load capable of being contained by the filter material is increased.

Description

technical field [0001] The invention relates to the field of filter materials for liquid fluids, in particular to a multi-layer fiber composite filter material, especially suitable for filter materials that still need to meet high-precision filtration requirements under special industrial and mining conditions, and also relates to a multi-layer filter material made of this filter material Fiber composite filter. Background technique [0002] Filtration is when the liquid (or gas) in the suspension (or the heating gas containing solid particles) penetrates the medium under the action of driving force or other external force, and the solid particles and other substances are trapped by the filter medium, so that the solid and other substances and the liquid ( or gas) separation operation. Therefore, the requirements for filter materials are higher, and they need to have better mechanical properties, usability and filtration properties. [0003] The filter element is a key com...
