Brief introduction/classification/price calculation of dust collector filter bags

Dust collector filter bags brief introduction:

Dusting cloth bag can be called the heart of bag filter. It is generally called filter dust bag, dust removal filter bag, dust collector filter bag, dust collection bag, dust collecting bag, dust collector cloth bag and so on. Dusting cloth bag is a key part in the operation of bag filter. Usually the cylindrical filter bag is suspended vertically in the duster.

It is the equipment that separates dust from flue gas. The bag filter is also called a filter type dust collector. It is a dry and efficient dust collector. It is a bag filter element made of fiber braid to capture solid particles in the dust gas. The principle is that dust particles are intercepted by the impact of inertia force and fibers when they pass through filter cloth fibers.

 

Dust collector filter bags classification:

-According to the processing method, it is mainly divided into three classifications: woven cloth (filter media) filter bag, nonwoven cloth filter bags and compound materials filter bags.

Woven filter media filter bag: loom is used to vertically arrange yarn and weft yarns arranged vertically according to certain organizational rules, expressed in letter W.

Non-woven filter bag: without the general spinning and weaving process, the fiber into a net or yarn into a layer, interlaced, glued, needled, melted or spinning, a piece of filter material made up of letters NW and the code of the specific processing method of the compound letter;

Composite material filter bags: filter bag made of more than two methods or made of two or more materials, which is represented by letter C.

- According to fabric organization, it can be divided into three types: plain cloth filter bags, twill cloth filter bags and satin cloth filter bags.

Plain texture: This is the simplest form of weaving, each of the warp and each of the weft is alternating, but the plain texture is difficult to clear ash and easy to plug in. Therefore, the weaving organization has been rarely used as a filter material.

Twill structure: it is made of two and four warp yarns and weft yarns. The weft yarn interlacing points gradually move to the left or right; the twill is divided into single and double twill. The flexibility and elasticity of the twill fabric are superior to those of the plain weave. The mechanical strength is slightly lower and the force is easily misplaced after force, but its wearability is good and the dust removal efficiency is good. It is also the most commonly used structure for woven filter media.

Satin texture: the warp or weft can be divided into warp and weft forged lines on the surface of the fabric. The forged texture is characterized by smooth, glossy, very soft, flexible and breathable, and easy to remove ash due to the mobility of the yarn.

 

- According to the shape of the filter bag cross section, it can be divided into three types: circular, flat and special shaped filter bags.

Circular: dust filter bag is cylindrical. Its specifications are expressed in diameter by D * L (mm).

Flat shape: filter bag is flat, including rectangle and trapezoid, and its specification is expressed by circumference * length (P * L (mm)).

Special-shaped filter bags: specific shape filter bag, its specification is expressed by the characteristic parameters of its structure.

 

-According to the filtration way, it can be divided into two types: internal filtration and external filtration filter bags.

Internal filtration filter bags: dust containing gas is filtered through the inner surface of the filter bag, and dust is obstructed on the inner surface of the filter bag. This filtration method is called internal filtration.

External filtration baghouse filter bags: Dusty gas is filtered through the outer surface of the filter bag and the dust is obstructed on the outer surface of the filter bag. This filtration method is called external filtration.

 

Dust collector filter bags price calculation:

We will show you to calculate the price of dust collector filter bags made of the most common material.

The formula is: (diameter *3.14+0.03) * length * unit price so that the price of a cloth bag can be calculated.

The diameter here refers to the diameter of holes in the cell plate you installed. The unit price refers to the price per square meter (according to the different materials, the prices of different manufacturers are not the same).
