Dust removal bag product overview:
The dust bag is the heart of a bag dust collector, and is generally called a filter bag, a dust filter bag, a dust collection bag, a dust bag, a dust bag, a dust bag.
The dust bag is a key part of the operation of the bag type dust collector. Generally, the cylindrical filter bag is suspended vertically in the dust collector.
Bag classification:
I. Processing method
According to the processing methods, it is mainly divided into three categories: woven filter dust bag, non-woven filter dust bag and composite filter dust bag.
1. Woven filter dust collector filter bag: The filter material woven by warp and weft yarns arranged vertically with each other according to a certain organization with a loom, represented by the letter W;
2. Non-woven filter dust-collecting filter bag: without the usual spinning and weaving process, the fiber is directly formed into a net or a layer of yarn, staggered, bonded, needle punched, melt blown or spun into a sheet shape Filter material, compound letters composed of the letter NW and the code of the specific processing method;
3. Composite filter dust-removing cloth bag: The filter material for dust-removing cloth bag made by two or more methods or compounding two or more materials, is represented by the letter C.
Second, the fabric organization
According to the fabric organization, it is mainly divided into three categories: plain filter dust bag, twill filter and forged filter.
1. Plain weave: This is the simplest form of weaving. Each warp and each weft are alternated up and down, but the plain weave has the disadvantages of difficulty in cleaning and clogging. Therefore, this kind of weave has rarely been used as a dust filter ;
2. Twill weave: It consists of two upper and four lower warp yarns interlaced with weft yarns at the same time. The weaving point of warp and weft yarns gradually moves to the left or right; the twill weave is divided into single-sided twill and double-sided twill; the flexibility of twill weave And elasticity are better than plain weave, mechanical strength is slightly lower, easy to displace after being stressed, but its wear resistance is good, dust removal efficiency and dust removal effect is also good, is the most commonly used organization of woven filter material;
3, forged texture: warp or weft can be divided into warp and weft according to the surface of the fabric; forged texture is smooth, shiny surface, very soft, elastic and breathable At the same time, because the yarn has mobility, it is easy to clean.
Filtering method
According to the filtering method, it is mainly divided into two types: internal filtering type and external filtering type.
1. Internal filter dust bag: After the dust-containing gas is filtered by the inner surface of the filter bag, the dust is blocked on the inner surface of the filter bag. This filtering method is called internal filtering type;
2. External filter type dust collector filter bag: After the dust-containing gas is filtered by the outer surface of the filter bag, the dust is blocked on the outer surface of the filter bag. This filtering method is called external filtering type.
