Problems solved by technology

[0005] However, the surface pore diameter of the filter material is small, and coarse dust, medium dust, and fine dust are all blocked on the surface of the filter material to form "surface filtration", which virtually increases the air permeability resistance of the filter material and reduces the filtration speed of the filter material. , thus affecting the effect and efficiency of high temperature flue gas and dust purification

Abstract

The invention provides a high-temperature dust-removing and filtering sleeve. The high-temperature dust-removing and filtering sleeve comprises a first dust-removing pipe, a second dust-removing pipeand a plug, wherein a bottom-end pipe opening of the first dust-removing pipe is inward sealed to form a blind hole, and a top-end pipe opening of the first dust-removing pipe extends outward to forman annular plane; the porosity of the first dust-removing pipe is 85 percent to 95 percent and the pore diameter of air pores is 30 mum to 50 mum; the second dust-removing pipe is embedded into the first dust-removing pipe; the bottom-end pipe opening of the second dust-removing pipe is inward sealed to form a blind hole, and the top-end pipe opening of the second dust-removing pipe extends outward to form an annular plane; the outer diameter of the second dust-removing pipe is smaller than the inner diameter of the first dust-removing pipe and a cavity is formed; a plurality of exhausting holes, which penetrate through the cavity, are formed in the annular plane of the second dust-removing pipe; the porosity of the second dust-removing pipe is 75 percent to 85 percent and the pore diameter of the air pores is 10 mum to 30 mum; the plug is used for sealing the second dust-removing pipe; the plug is provided with exhausting hole plugs corresponding to the exhausting holes. The high-temperature dust-removing and filtering sleeve provided by the invention adopts a specific structure and rapid and deep filtering can be realized; when being used for purifying high-temperature flue gas and dust, the high-temperature dust-removing and filtering sleeve has a relatively good effect and relatively high efficiency.

Description

technical field [0001] The invention relates to the technical field of high-temperature flue gas and dust purification, and more specifically relates to a high-temperature dust removal filter sleeve and a preparation method thereof. Background technique [0002] At present, my country's dust removal technology system is facing the second revolution in the field of high-temperature flue gas and dust purification technology. One of its important technical measures is the use of filter dust removal technology. In recent years, with the unremitting efforts of scientific researchers, filtration and dust removal technology has made great progress. [0003] The Chinese patent with the publication number CN1792412A discloses a ceramic-based composite material filter tube for cleaning high-temperature gas flue gas and its preparation method. The filter tube has a blind hole at one end and an open end, and the silicon carbide ceramic is toughened by continuous aluminum silicate fibers...
