Abstract

The invention relates to a preparation method of a high-temperature gas filter material for three-dimensional orthogonal woven fabric bag-type dust removal equipment. The preparation method comprises the following steps: adopting two or more than two layers of filament yarns as warp yarns of a three-dimensional fabric, three or more than three layers of air textured yarns as weft yarns of the three-dimensional fabric and two layers of Z yarns as Z-direction binding yarns of the three-dimensional fabric so as to obtain the high-temperature gas filter material for three-dimensional orthogonal woven fabric bag-type dust removal equipment through spinning. The method is simple in operation, the equipment investment and operating cost are low, the method is convenient for popularization and application, and the production for energy conservation and emission reduction can be realized. The prepared and obtained filter material has excellent filter performance, mechanical property and high temperature resistance, and has the advantages of low resistivity, high efficiency, long service life and the like; the emission of PM2.5 particulates can be effectively reduced; and the filter material is beneficial for controlling fog and haze weather and optimizing the air quality.

Description

technical field [0001] The invention belongs to the field of filter material preparation, in particular to a method for preparing a high-temperature gas filter material for a three-dimensional orthogonal fabric bag-type dust removal device. Background technique [0002] PM 2.5 is the main cause of haze weather. In 2014, from the perspective of local PM2.5 emissions in Beijing, motor vehicles accounted for 31.1%, coal combustion accounted for 22.4%, industrial production accounted for 18.1%, and dust accounted for 14.3%. Farming, etc. accounted for 14.1%. It can be seen that the high-temperature exhaust gas emissions from the three major areas of motor vehicles, coal combustion, and industry account for more than 70% of the total emissions. Therefore, in recent years, various countries have actively developed various high-performance high-temperature gas filter materials to meet the requirements of high-temperature gas dust removal. [0003] High-temperature gas filtration...
