A spiral high-efficiency low-resistance filter element made of iron-aluminum alloy

Abstract

The invention discloses a spiral efficient low-resistivity filter core made of a ferro-aluminium alloy, and belongs to the field of filter core design of a dust remover. The filter core is made of a ferro-aluminium alloy filter material, and is bent into a spiral shape, and a filter core body is supported by a metal grid. The filter core mainly comprises the filter core body, an exhaust pipe, a back pulse jetting linkage device, top caps, valves, and the like, wherein the filter core body adopts a cylindrical spiral structure; bore diameters of the spiral filter core body are decreased from inside to outside in an arithmetic progression form. During practical operation, after smoke is filtered through the filter core layer by layer, most dust is stopped outside the filter core, a purified gas enters the inner filter core, is filtered layer by layer, and finally, is discharged into the next procedure through a smoke exhaust pipe. The spiral efficient low-resistivity filter core solves the core problem that a dust remover in the current market is low in dust removing efficiency and weak in high temperature resistance and sulfuration resistance.

Description

technical field [0001] The invention belongs to the field of filter element design for dust collectors, and specifically relates to the preparation of Fe-Al intermetallic compound porous filter material, the change of the maximum pore size of the filter material, and the relationship between the spiral structure of the filter element and the dust removal efficiency, and completes the design of the filter element of the dust collector under different requirements. Optimal design scheme. Background technique [0002] A large amount of dust and toxic and harmful gases will inevitably be produced in the process of modern industrial production. In recent years, problems such as smog and acid rain have intensified and seriously threatened human health. Therefore, reducing regional atmospheric fine particle pollution and reducing the concentration of sulfur dioxide in urban air have become a top priority for environmental protection. [0003] In recent years, filtration technology...

AI Technical Summary

Problems solved by technology

[0005] After years of research, people have a further understanding of the structure and properties of Fe-Al alloys. In order to make them widely used, it is necessary to improve the Fe-Al alloy on the basis of its excellent corrosion resistance, low density and low cost. Its low ductility at room temperature and low creep resistance at high temperature
