Problems solved by technology

Electrostatic discharge will cause holes in the filter material, which will make the filter material filter invalid
At the same time, the holes also reduce the strength of the filter material, resulting in damage to the filter material.
[0003] At present, the filter material used in the electric bag composite dust collector cannot produce the function of de-electrostatic coupling because there is no corresponding de-electrostatic coupling functional fiber material, and the filter material is easily damaged, and the discharge is not up to standard.

Abstract

The invention discloses a high-temperature filter material with the function of removing electrostatic coupling by using base fabric for an electric-bag composite dust-collector and a production method thereof, belonging to the technical field of high-temperature filter materials. The filter material for the electric-bag composite dust-collector is formed by clamping the base fabric between two fiber layers; the fiber layers consist of fibers with the functions of resisting high temperature and removing electrostatic coupling and high-temperature fibers; the base fabric has a mesh structure formed high-temperature yarns; and stainless steel fiber yarns, carbon fiber yarns or titanium fiber yarns are decided to be spaced according to the demand of the function of removing electrostatic coupling. The high-temperature filter material can be obtained by using a needle punching method and a hydroentangling method. The invention has the advantages that the filter material can remove the electrostatic coupling by combining the functional fibers and the high-temperature fibers and prevent the soot in a filter bag of the electric-bag composite dust-collector from leaking due to discharge damage and the dust collector from losing efficiency. Meanwhile, the filter material has high production efficiency and low production cost.

Description

technical field [0001] The invention belongs to the technical field of high-temperature filter materials, and in particular relates to a high-temperature filter material with a base cloth for electrostatic coupling of an electric bag composite dust collector and a manufacturing method thereof. Background technique [0002] In recent years, a high-efficiency dust collector-electric bag composite dust collector has been used in various industries in the treatment of atmospheric environment. The dust in the dust collector is charged by the electric field, resulting in the formation of a strongly charged dust layer on the surface of the filter bag. Due to electrostatic coupling, an electrostatic field is generated between the dust layer and the filter material, and the electrostatic voltage increases with the thickening of the dust layer. If the electrostatic voltage reaches a certain value, electrostatic discharge will occur. Electrostatic discharge will cause holes in the fi...
