alkali-free professional manufacturer of fiberglass filter cloth


PTFE Needled Felt Filter Bag

PTFE needled felt is made of high quality PTFE short fiber and filament fiber as the main raw material. Adopt domestic advanced production technology, we focus on the waste incineration power generation, glass furnace, medical waste incineration, petrochemical, ceramics, chemical, gold, food industry, building materials, biological power generation and other industries to provide a system of flue gas dust filtration technology solutions.


High filtering precision, 99.99% efficiency, nearly zero emissions. Extremely stable chemical properties. Continuous operating temperature 260℃, instant temperature 280℃. Completely anti-aging chemical characteristics, suitable for working conditions with high water vapor content. Meet the worst working conditions and have a long service life.(Up to five years under normal working conditions).

Solid Waste Incineration Industry

Operating characteristics of refuse incineration

  • The composition of garbage is complex, causing great harm and requiring high governance.
  • The flue gas temperature and the amount of flflue gas are unstable, and the flue gas temperature is between 140-260℃.
  • High smoke temperature, up to 60%, easy to paste bags.
  • The flue gas has a high dust concentration, up to 50g/m3, with light and fine dust.
  • The content of corrosive substances in the flue gas is high, leading to the rise of acid dew point.

Cement Industry/Lime Kiln

Working condition characteristics of cement kiln end (similar working condition of lime kiln) 

  • CaCo3 dust is originated in the raw cement, which is not completely decomposed in the decomposition furnace. And CaO dust generated during the decomposition of CaCo3.
  • The SO, NO, CO, CO2 and other gases produced during the combustion of pulverized coal.
  • The temperature of the kiln tail exhaust gas coming out of the cyclone is above 320C, the gas is dry.
  • The concentration of the smoke dust is 40-130mg/Nm3,the dust particle size is less than 1μm and accounting for more than 90%.
  • The content of CO and CO2 sometimes fluctuate according to the sufficiency combustion of pulverized coal.

Chemical Industry (Carbon Black, Tianium Dioxide)

Working condition characteristic of Chemical industry

  • The initial concentration is high. Carbon black is a nano-level substance with small particle size, small specific gravity and strong adhesion.
  • The working temperature of the main fifilter is 270-280℃,and the working temperature of waste fifilter is around 250℃.
  • The working temperature of the oil preheater is above 350℃.When the temperature reach 4 00℃, it needs to sprayed water to cool down the temperature. There are large amount of CO,SO2,SO3, which will produce sulfurous acid.
  • It contains gas, which is flflammable and explosive, and has high water vapor. Spraying 1 ton of water will produce 1600M3 water vapor.
  • Inlet pressure is 200Pa, outlet pressure is 3500-4000Pa, and back air pressure is 5000pa.

Electric Power Industry

Operating characteristics of coal-fired power plants

  • Dust concentration at the inlet of the dust collector is relatively high.
  • The contents of SO2,NOX,02,03 and other components in the flue gas which have a strong destructive efect on the filter material are relatively high.
  • The amount of smoke fluctuates greatly due to the variation of coal type and power generation load.
  • The filtering wind speed is generally around 1.0, and most ash cleaning methods are pulse ash cleaning or rotary back-blowing.
