Abstract

The invention relates to the technical field of a filter pipe, and in particular relates to a foamed ceramic high-temperature gas filter pipe and a manufacturing technology thereof. The foamed ceramic high-temperature gas filter pipe comprises 10-30 parts of Al2O3, 10-40 parts of SiO2, 10-30 parts of SiC, 1-3 parts of nano calcium carbonate, 5-10 parts of refractory clay, 1-2 parts of rectorite and 0.5-1.5 parts of sodium bentonite. According to the invention, the average aperture of the filter pipe is 20-250 mu m, the porosity can reach 75-85%, the gas permeability can be improved, and the pressure loss of the filter pipe in work is effectively reduced so that the energy consumption of a draught fan of a dust collector is reduced by 20-30% and the effect of saving energy is achieved; and the manufacturing technology comprises the steps of mixing materials, forming, firing and the like, wherein the firing process is performed under normal pressure, the requirements on equipment and the like are low, the energy consumption is low.

Description

technical field

[0001] The invention relates to the technical field of filter tubes, in particular to a foam ceramic high-temperature gas filter tube and a preparation process thereof. Background technique

[0002] In modern industrial production, the field of purification and dust removal involving high-temperature dust-containing gas is very extensive. At the same time, the purification and dust removal of high-temperature dust-containing gas is also one of the problems that must be solved in modern industrial production to achieve environmental protection. However, due to the characteristics of high temperature and strong gas corrosiveness in the process of high-temperature gas purification and dust removal, there are high requirements for the filter materials used. Porous ceramic materials have excellent thermal stability and corrosion resistance. Working at a temperature of 1000°C, and having the advantages of good gas permeability and long service life, it has become t...
