Abstract

The invention belongs to the field of filter materials and particularly relates to a high-temperature-resistant filter material, a preparation method thereof and a high-temperature-resistant dust-removing filter pipe. The high-temperature-resistant filter material is prepared by mixing, by weight, 40-60 parts of ceramic fibers, 15-20 parts of organic fibers, 5-10 parts of organic binder and 20-30parts of inorganic binder with water and then performing calcining, wherein the dimeter of the ceramic fibers is 2-5 micrometers, the length of the ceramic fibers is 30-100 micrometers, the organic fibers comprise one or more of polypropylene fibers, polyester fibers and viscose fibers, and the length of the organic fibers is 6-10mm. The high-performance high-temperature-resistant filter materialprepared by optimally selecting the raw materials has a fiber interwoven structure inside, is good in mechanical strength and thermal shock resistance and has rich and communicated pores inside, and the dust removing efficiency of the material is increased greatly.

Description

technical field [0001] The invention belongs to the field of filter materials, and in particular relates to a high-temperature-resistant filter material, a preparation method thereof, and a high-temperature-resistant dust removal filter tube. Background technique [0002] Petrochemical, metallurgy, electric power and other industries usually produce high-temperature dust-containing gas during the manufacturing process. If the dust in the high-temperature dust-laden gas is not filtered and separated, it will not only pollute the environment, but also bring inconvenience to the heat energy recovery of the high-temperature gas. Therefore, the high-temperature dust-laden gas must be dedusted. [0003] The research and development of high-temperature gas dust removal technology began in the 1970s. The traditional dust removal method is mostly wet dust removal. The high-temperature gas is cooled first, and then the dust is removed in a cold state, which wastes a lot of heat resour...
