Our factory can customize various specifications, materials (at room temperature, medium temperature, high temperature), shapes, and dust collector bags/filter bags. Fast customization and delivery. We also provide supporting facilities such as dust removal skeletons, customized according to specifications and samples, including circular, stepped, and elliptical shapes, materials such as carbon steel and stainless steel plates, and surface solutions such as hot-dip galvanizing, electrostatic spraying, and silicon materials.

High temperature dust removal bag manufacturers produce dust removal bags with various specifications and models of filter bag materials, including cloth bags, oil resistant (oil repellent) bags, polyester cloth aluminum silicate needle punched blanket bags, 208 and 729 material bags, covered sub membrane dust removal filter bags, and Metas P84、PPS、 Polytetrafluoroethylene, fiberglass, etc.

Dust bag can be called the cardiovascular of bag filter, generally referred to as filter box, ash removal filter bag, dust bag, dust accumulation bag, dust removal bag, dust collector bag, etc. The dust removal bag is an important part of the entire operation process of the bag filter. Generally, the cylindrical filter bag is suspended vertically in the dust removal equipment.

Classification of Dust Removal Bags

1、 Production and processing methods

According to the key production and processing methods, it can be divided into three types: knitted yarn filter dust bag, non-woven filter dust bag, and composite filter dust bag.

1. Knitted yarn filter material dust removal equipment filter bag: a filter material woven from vertically arranged warp and weft yarns using a textile machine according to the regularity of the mechanism, indicated by the English letter W;

2. Non woven filter material dust collector filter bag: a block filter material made by immediately laying chemical fibers or cotton yarn into layers, overlapping, bonding, needle tying, melt spraying or spinning without going through the general textile and weaving process. It is indicated by a composite English letter consisting of the letters NW and the actual production and processing method number;

3. Composite filter material dust bag: A dust bag filter material made by combining two types of materials or two types of raw materials, indicated by the English letter C.

2、 Textile Structure

According to the key textile structure, it can be divided into three types: plain cloth filter material dust bag, twill cloth filter material, and forged grain filter material.

1. Plain weave fabric mechanism: It is a simple textile method where each tube yarn and each weft yarn is alternated left and right. However, plain weave fabric mechanisms have defects such as inability to remove dust and ease of blockage. Therefore, such textile mechanisms are rarely used as dust removal filter materials;

2. Twill fabric mechanism: It is composed of two upper and four lower tube yarns interlaced with weft yarns, and the interlacing points of warp and weft yarns gradually move to the left or right; The twill fabric mechanism is divided into single-sided and double-sided twill fabric and double-sided twill fabric; The flexibility and extensibility of twill fabric weaving machines are better than those of plain fabric weaving machines, with slightly lower impact toughness and easy displacement after bearing force. However, their performance is good, and the actual effect of ash removal is also good. They are a common mechanism for knitted yarn filter materials;

3. Forging mechanism: It can be divided into warp forging and weft forging based on whether the yarn heard on the surface of the textile is tube yarn or weft yarn; The characteristics of the forging mechanism are smoothness, glossiness, softness, good ductility and breathability. In addition, due to the transferability of cotton yarn, it is easy to remove dust.

3、 Cross section appearance of filter bag

According to the cross-sectional shape of the filter bag, it can be classified into three types: annular, flat, and irregular.

1. Circular: The ash removal filter bag is cylindrical in shape. The specifications and models are indicated by diameter x length, i.e. D x L (mm);

2. Flat type: The filter bag of the dust removal equipment is flat and includes a rectangular frame and a ladder shape. Its specifications are indicated by diameter x length, i.e. P x L (mm);

3. Heterogeneity: Filter bags with specific appearance, whose specifications and models are indicated by their structural characteristic parameters.

4、 Consideration method

According to the filtering method, it can be divided into two types: internal filtering and external filtering.

1. Internal filter dust bag: After passing through the inner surface of the filter bag for filtration, the smoke and dust are isolated on the inner surface of the filter bag. This type of filtration method is called internal filter.

2. External filtering dust removal equipment filter bag: After the smoke and dust vapor are filtered on the outer surface of the filter bag, the smoke and dust are isolated on the outer surface of the filter bag. This type of filtering method is called external filtering.
