Dust Filter Bag

Expanded glass fiber filter cloth weft yarn, referred to as glass fiber filter cloth, consists of puffed yarn. This product is mainly used for high-temperature atmospheric dust reduction and recovery of valuable industrial dust. Because the yarn is fluffy, the covering ability is strong, and the gas permeability is good, the filtration efficiency can be improved, the filtration resistance can be reduced, and the dust removal efficiency can reach 99.5% or more. The product is mainly used for high-temperature atmospheric dust reduction and recovery of valuable industrial dust. For example, cement, carbon black, steel, metallurgy, electric power generation and coal-fired furnaces and other industries. There are many varieties of glass fiber, including continuous fiber, fixed length yarn, and bulked yarn. They can be individually or mixed into filter cloths, and in recent years there have been fiberglass needle felts. In terms of filtration performance, continuous glass fiber permeability is similar to cotton yarn. The fixed length fiber yarn has good bulk and air permeability and good dust collection efficiency. The glass fiber bulked yarn is formed by the continuous glass fiber being blown by compressed air, so that the fibril is shortened and wound into a roll, which is bulky and bulky, and the volume is doubled, and the strength is obviously reduced. According to the comparison of the filtration performance of various fabric structures of the glass fiber expanded yarn, it is preferable to retain the warp continuous fibers. Its cost is low, the glass fiber needle felt uses a thicker base fabric, and then is coated with ultra-fine short fibers. The fibers are pierced into the bottom with hundreds of needles to form a three-dimensional structure, which increases the airflow path and prevents dust. to raise efficiency. The surface of the filter cloth is heat treated to evenly flatten the surface, eliminating large pores, reducing the penetration and penetration of fine dust, thereby increasing the filtration speed.

The P84 filter bag is a high-efficiency and low-resistance filter material which is mainly made of glass fiber and compounded with P84 fiber to form a three-dimensional microporous structure. After special surface chemical treatment and finishing technology, the product is resistant to acid and alkali corrosion, wear and tear, and it is resistant to water and oil, easy to clean and so on. The peeling strength is >40N, which can bear high air volume and high concentration dust collection efficiency. The characteristics of the P84 composite high temperature resistant filter bag is significant due to the fineness of the fiber itself. The irregular fiber cross section increases the fiber surface area to the maximum and provides many tiny pores to make the surface filtration better than the depth filtration. The dust only stays on the surface of the filter mat and cannot penetrate into the filter mat. Therefore, the backwashing pressure is small and the filter cake bombing efficiency is remarkably improved, and the fine fine particle collecting efficiency is excellent and the working pressure difference is small. Scope of application: Applicable to coal-fired boilers, liquid bed boilers, waste incineration, asphalt plants, cement plants, waste incinerators, thermal power plants, etc. P84 has the following characteristics 1. the use of the continuous temperature up to 260 degrees, the instantaneous temperature can reach 280 degrees; 2. It has good acid resistance, alkali resistance; 3. Hydrolytic stability is significantly better than NOMEX fiber.

Polyester needle felt is a fine fiber cloth which adopts a non-woven needle punching process and uses fiber staggered and uniform void distribution. The surface of the needle felt produced by polyester staple fiber and polyester crepe is hot rolled, singeed or coated. After treatment, the surface is smooth and not easy to be blocked by dust. The filter material has large void ratio, good gas permeability, wide application, strong chemical stability, not only filtering normal temperature gas, but also filtering acid and alkali. Corrosive gas, and can filter water, filter oil, is normal temperature conditions. Ideal filtration materials in the fields of liquid-solid separation.

Product description Product description PPS needle-punched filter felt is made of imported 100% PPS fiber. PPS fiber has excellent acid and alkali resistance and oxidation resistance, wear resistance and folding resistance. Normal temperature resistance up to 180 ° C, short-term up to 210 ° C, suitable for thermal power, waste incineration, coal-fired boilers and other high sulfur containing flue gas filtration.

P84 needle felt is made of three-dimensional needles made of P84 fiber (ie, polyurethane fiber) produced by Austrian LENZING company. It has good high temperature resistance, temperature resistance up to 280 °C, and P84 fiber section is irregular. Shape, can greatly improve the filtration effect, the fiber itself has certain resistance to hydrolysis and oxidation. The product has good temperature resistance and good filtration effect, and is widely used in complex conditions such as concrete mixing, cement, garbage incineration, coal-fired boilers, etc. Use under conditions.

Generally, when the concentration of industrial dust reaches a certain level (ie, the explosion limit), in the case of static discharge sparks or boundary ignition, it is easy to cause explosion and fire. Such as: flour dust, chemical dust, explosive dust and so on. In the case of electrostatic discharge, there is an explosive nature. In the field of bag dust removal, if these dusts need to be collected by cloth bags, the bags themselves are required to have anti-static function. In addition to the production of ordinary needle felt process, the production of anti-static filter materials also requires the production of needle felts. The conductive fiber yarn is incorporated into the warp of the base fabric.

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.

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.
