Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present invention.

[0024] Such as Figure 1-3 As shown, a bipolar filter bag includes a bag body 1. The filter cloth of the bag body 1 is composed of one layer of long fiber layer 2 and two layers of short fiber layers 3. The short fiber layers 3 are respectively arranged on the sides of the long fiber layer 2. On both sides, the warp yarns 4 and weft yarns 5 of the staple fiber layer 3 are made of a mixture of cathode and anode fiber materials.

[0025] The cathode fiber mat...

Abstract

The invention discloses a bipolar filter bag and a manufacturing process thereof. The bipolar filter bag comprises a bag body; a filter cloth of the bag body is composed of a long-fiber layer and twoshort-fiber layers, wherein the short-fiber layers are respectively arranged on two sides of the long-fiber layer, and warp yarn and weft yarn of the short-fiber layers are prepared by mixing a cathode fiber material and an anode fiber material. According to the bipolar filter bag, an effect that different charges are carried by different parts of one same filter bag can be realized, and positively charged dust and negatively charged dust can be adsorbed, so that a filtering effect is effectively enhanced. In addition, the bipolar filter bag has the advantages of easy ash removal, oxidation resistance, high strength, acid and alkali resistance, high temperature resistance and the like.

Description

technical field [0001] The invention relates to the technical field of industrial dust removal, in particular to a bipolar filter bag and a manufacturing process thereof. Background technique [0002] The filter bag has excellent chemical performance stability and heat resistance. It is the representative of the highest performance in the filter material industry, and it is also the most high-end variety of all commonly used filter materials. Commonly used filter materials include PE, PP, PTFE, PMIA, NMO, etc. [0003] The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filtering effect of the fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and specific gravity will When the air containing fine dust passes through the filter material, the dust will be blocked and the air will be purif...
