As we all know, ptfe coated filter bags have excellent properties that ordinary dust bags cannot match. The filtration efficiency of the coated ptfe composite filter paper can be as high as 99.99% Above, because of its efficiency, it ranks first in the dust removal industry. Let’s talk to you about the main industries used after dust removal filter bags are covered with our ePTFE microporous membrane!
Waste incineration is currently one of the very important application fields of PTFE coated filter bags. The garbage incineration process will inevitably produce a large amount of pollutants, which have the following characteristics:
1. There are particulate matter, acidic gases, heavy metals and Organic highly toxic pollutants;
2. The flue gas has high moisture content, high dew point temperature, and the filter is prone to condensation;
3. High and low temperature flue gases alternately exist;
4. The particles produced by deacidification treatment easily absorb moisture and lead to dust cleaning Difficulties and pipe blockage;
5. Flue gas is highly corrosive.
Filter bags made of needle-punched felt filter material with PTFE as the base fabric and P84 as the surface layer and coated with PTFE microporous membrane are used in waste incineration power plants Good results can be achieved in flue gas purification.
Coal-fired power plants
Coal-fired power plants are common in our country, and the coal combustion process A large amount of sulfur dioxide, nitrogen oxides and respirable particulate matter will be produced. Due to the excellent properties of PTFE, bag dust collectors made of composite filter materials made of PTFE membrane and temperature-resistant fiber needle felt such as glass fiber can greatly reduce smoke and dust emissions from power plants in high-temperature environments. In addition, the composite filter material of PTFE membrane and glass fiber needle felt is recognized as a very good material to overcome inhalable particulate matter.
Cement industry
As my country’s energy conservation and emission reduction requirements become more and more stringent, The electrostatic precipitators traditionally used in the cement industry can no longer meet the new national emission standards. In the cement production process, the bag dust collector made of traditional needle felt composite ptfe composite filter paper can reduce the emission of air pollutants and recycle cement powder, which can increase production and reduce cost and energy savings.
Laboratory purification field
Air cleanliness in the biological, food and pharmaceutical industries In the field of higher-level clean rooms, ptfe composite filter paper filters have the characteristics of good stability, corrosion resistance, and large flow rate under the same resistance conditions. They can meet the requirements of air filtration and will be used in these industries. Give full play to greater application value and economic and technical potential.
The currently independently developed ptfe composite filter paper is the core raw material of industrial dust removal film-coated filter bags and is widely used in cement, coating The treatment and recycling of flue gas and dust particles in industrial fields such as , petrochemical plastics, food, metallurgy, etc. can greatly reduce maintenance and operating costs.
