Problems solved by technology

This brings the following problems: Whether it is adhesive coating or high-temperature hot-press coating, the PTFE microporous membrane is almost completely bonded to the plane of the woven fabric substrate, and the entire membrane surface of the PTFE microporous membrane is subjected to high temperature and pressure. The damage of the film will reduce the strength and air permeability of the membrane; and the use of traditional adhesives will also block the micropores of PTFE due to the rolling of adhesive points, resulting in a decrease in air permeability;

Embodiment Construction

[0030] refer to Figure 1 to Figure 2 A further description will be given to an embodiment of a dust removal filter material for waste incineration flue gas and its processing method of the present invention.

[0031] For ease of description, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the position of one element or feature shown in the figures relative to another element or feature. relation. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orient...

Abstract

The invention discloses a dust removal filter material for waste incineration flue gas and a processing method thereof. The main point of the technical solution of the processing method of the air dust filter material is that the woven cloth base material is provided with bumps, and the PTFE microporous film is compounded on the bumps; the plane tension of the woven cloth base material is greater than the plane of the PTFE microporous film. Tension; with the above structure setting, the filter material greatly improves the filtration efficiency, increases the air volume, and prolongs the service life; at the same time, the damage of the PTFE microporous membrane during the preparation process is greatly reduced, and there is no fiber breakage and flexibility. Good; the plane tension of the woven fabric base material is greater than that of the PTFE microporous membrane, which effectively overcomes the phenomenon of low temperature membrane cracking, and the invention is suitable for the technical field of dust removal and filter materials.

Description

technical field [0001] The invention relates to the technical field of dust removal filter material, more specifically, it relates to a dust removal filter material used for waste incineration flue gas and a processing method thereof. Background technique [0002] In the atmospheric dust removal industry, the film-coated filter material is widely used due to its surface filtration characteristics of high filtration efficiency, low running resistance, easy and less cleaning times, large air volume and long service life. There are two kinds of film-covering processes for film-coated filter materials: one is the binder method, and the other is the high-temperature hot-pressing method. The former is gradually eliminated due to the poor temperature resistance of the binder and the aging of the binder, while the latter is a widely used process. Since the base material of the woven fabric coated filter material is flat, in the process of covering the film, the PTFE microporous mem...
