The special polyphenylene sulfide pps dust-removing cloth bag for coal-fired power plants uses PPS fiber base cloth and high-performance PPS fiber gradient layers with different finenesses. The entire PTFE emulsion is impregnated and the filter material is coated with PTFE. Polyphenylene sulfide pps dust-removing cloth bags for coal-fired power plants can play an aspiring role in removing a lot of smoke and fumes from the production of chemical enterprises such as thermal power generation, steel, cement, etc., to reach the atmospheric emissions of such enterprises. Claim. The dust bag itself is made of clean filter cloth in a neat production environment to eliminate secondary pollution. Filter bags made of non-woven fabrics are treated by scorching and calendering to avoid secondary pollution caused by fiber shedding.

Polyphenylene sulfide pps dust removal bag for coal-fired power plants The special advantages of needled felt made of polyphenylene sulfide fiber are shown in the following aspects: PPS filter bag, PPS needle felt, high temperature dust removal bag, special filter bag for chemical power .
1. Outstanding temperature resistance Melting point is 285 ℃, continuous operating temperature is 190 ℃, instantaneous operating temperature is 230 ℃.
2. Excellent corrosion resistance polyphenylene sulfide fiber fibers are better than Nomex Conex and Kermel fibers in terms of resistance to organic acids, inorganic acids, acids and oxidants.
3. The extreme oxygen index (LDI) of the excellent flame-retardant polyphenylene sulfide fiber is 34-35. This fiber is a non-combustible material for PPS needle felt. Polyphenylene sulfide fiber needle punched felt not only has the function of high temperature resistance, but also has the function of anti-corrosion. Widely used in exercise, chemical, building materials, thermal power, waste incinerators, coal-fired boilers and other occupational high temperature and harsh working conditions, it is a high-quality high-efficiency high-temperature filter material. The polyphenylene sulfide fiber produced in the United States and Japan is used. According to other high-temperature needle-punched felt production processes, the professional production of polyphenylene sulfide (PPS) needle-punched felt has reached the level of similar products in developed countries.
PPS ＋ PTFE treatment dust-removing filter bag
In the field of bag-type dust removal, PPS high-temperature resistant dust-removing cloth bags usually compare the dust-removing cloth bag to the heart of the bag-type dust collector. What kind of dust-containing smoke can be handled by the bag-type dust collector. The condition of the bag's chemical fiber itself. Under normal flue gas temperature conditions, it is only necessary that the dust removal filter bag can withstand temperatures below 150 ° C. In these occasions, polyester, polypropylene, acrylic, nylon and other chemical fibers can basically serve. In the case of relatively high flue gas temperature, such as: chemical industry, carbon black (white carbon black) exhaust gas, iron blast furnace gas, cement plant vertical kiln exhaust gas, calcium carbide kiln exhaust gas, casting, steel mill flue gas, asphalt Concrete mixed with bitumen flue gas, PPS needle felt felt refractory brick kiln flue gas, coking flue gas, etc. One is that these dusty flue gas dust is not suitable for electrostatic precipitator collection due to the specific resistance constraint. PPS high temperature resistant dust removal bag It can only be collected with cloth bags or other methods; the second is the higher capital contribution or the constraints of the site if the temperature of the dusty flue gas is lowered below 150 ° C; the third is because the dusty flue gas contains sulfur components and contains Dust and smoke have acid "dew point". Dust-containing smoke can only be filtered and separated at a temperature above the dew point, that is, at a higher temperature. This requires a chemical fiber high-temperature cloth bag that can withstand higher temperatures. Make filter media.
Production process of special polyphenylene sulfide pps dust removal bag for coal-fired power plants: fiber opening-packing-laying-netting-pre-puncture-main thorn-felting-scorching-calendering-impregnated PTFE ( Waterproofing agent)-drying-setting-rolling-rolling.
Our company is the earliest manufacturer among the manufacturers of dust-removing equipment for the production of dust-removing equipment. Regarding the current selection of dust-removing bags by customers, especially those who have always used the filter materials developed in the 1980s and 1990s, it is now the choice of new types of dust-removing filter bags that can be qualified for discharge. The applicable working conditions of the materials are used to guide the determination.
Principles for selecting polyphenylene sulfide pps dust removal bag for coal-fired power plants
Bag-type dust collectors generally select dust-removing cloth bags based on the nature of the dust-containing gas, dust, and dust removal method of the dust collector. The selection should follow the following principles:
(1) Reasonable structure and high capture rate;
(2) Good peelability, easy to remove dust and difficult to scale;
(3) Suitable air permeability, low resistance and high filtration accuracy;
(4) Satisfactory strength and good dimensional stability;
(5) Has outstanding temperature resistance, chemical resistance, oxidation resistance, hydrolysis resistance and wide adaptability;
(6) Wide range of materials and stable functions;
(7) Low price and long life.
