Dust Collector Filter Bag

Polyester filter bags are used to treat air pollution and material recovery, and are suitable for operation at temperatures between 125 C and 140 C. The polyester needle-punched filter felt is a layered composite product of a textile woven fabric and a nonwoven needle-punched nonwoven fabric.


In the middle layer of the filter material, there is a woven base fabric layer which acts as a reinforcing steel frame to increase the strength. On the surface of the base fabric with a small tightness, the fiber-woven woven layer is laminated. The product has a three-dimensional structure, and its total opening ratio can reach more than 80%. The surface of the needle-punched cloth is arranged in a single fiber layer, and the number of cloth faces is large, the aperture is small, and the distribution is uniform, and the dust collection effect is good. Therefore, the needle felt has the advantages of high dust-pumping efficiency, good air permeability, low resistance and high air volume capacity.


Polyester (polyester) fiber filter material is used for temperatures from 125 C to 140 C. The polyester has excellent electrical insulation, good wear resistance, high strength and good elastic recovery performance, and the strength loss at 170 C can be recovered in a short time, and the thermal stability is good.


Polyester has poor hygroscopic properties and is easily hydrolyzed. It is more easily eroded under the conditions of containing sulfuric acid, nitric acid and carbonic acid. It is stable to low concentration of inorganic acid under low temperature conditions, but it is soluble in concentrated sulfuric acid and heated formic acid. It is stable to general organic solvents, has good resistance to weak bases, and is generally resistant to strong alkalis.

The surface of polyetrafluorethylene (PTFE) membrane is smooth and
anti-chemistry. PTFE membrane is bonded to the surface of conventional
filter medium and eliminates the need for a primary dustcake. Filtration
takes place on the membrane surface and realizes surface filtration.
Because the PTFE membrane has the advantage of smooth , chemical
stability, long service life and waterproof, it results in excellent dustcake
release, high filtration efficiencies and longer service life.

Dust Collector Bag Filter
Bag filter we should clearly know its main job is to remove dust, and has a good dust removal effect, favored by the vast number of users in the life, but we for its principle of work is not very understanding, today we are key to understand the working principle of bag filter, the following is introduced bag filter manufacturer.

Filter bag used textile filter cloth or non textile mat is made, using the fabric filter effect of dust filters, gas when dusty gas into the bag filter, large particles, major dust, due to the effect of gravity settling down, fall into the hopper, contains the fine dust of gas through the filter material, the dust were blocked, the purified gas.

Through the introduction of the above, we can better understand the working principle of bag filter, as the saying goes, only to know more about the knowledge of the product, to ensure better in the future, more knowledge about the bag filter, please pay attention to our website.
