Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] figure 1 A schematic structural diagram of an embodiment of the present invention is shown, figure 2 A schematic diagram of the metal fiber substrate of the present invention is shown. like figure 1 As shown, the present invention provides a metal fiber-based special high-temperature-resistant flue gas dust removal filter felt. Heat setting treatment to reinforce the composite filter felt.

[0027] The present invention also provides a metal fiber-based special high-temperature-resistant flue gas dust removal filter felt. Reinforced composite filter felt.

[0028] like figure 2 As shown, the metal fibers in the metal fiber substrate 2 are stainless steel metal materials, or copper fiber metal materials. The metal fiber base material 2 is a middle support layer composed of metal fiber crisscross woven diameter net, which is used to sup...

Abstract

The invention discloses metal fiber-based special high-temperature-resistant flue gas dust removal filter felt and a preparation method thereof. The filter felt is obtained by needling polyimide fiberlayers on the faces of a metal fiber base material and then conducting reinforcing and compositing through main needling or spunlace and heat setting treatment. The filter felt has the advantages that the extreme high-temperature reaching 400-5,000 DEG C can be borne, in high-temperature glue gas dust removal, the filter property of the product can be kept, and PM2.5 particles are effectively controlled.

Description

technical field [0001] The invention relates to a flue gas dust removal filter felt, in particular to a metal fiber-based special high temperature resistant flue gas dust removal filter felt and a preparation method thereof. Background technique [0002] At present, the flue gas dust collector sometimes has extreme high temperature phenomenon, and the conventional high temperature resistant dust removal filter felt can no longer meet the application of the actual working conditions. This is where this application needs to focus on improving. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a metal fiber-based special high-temperature-resistant flue gas dust-removing filter felt that is applied to extreme high temperature conditions and a preparation method thereof. [0004] In order to solve the above technical problems, the present invention provides a metal fiber-based special high-temperature-resistant flue gas...
