As we all know, the PTFE coated dust filter bag has excellent characteristics that ordinary dust filter bags can't match. The filter efficiency after the film can be as high as 99.99% or more. Because of its high efficiency, it ranks first in the dust removal industry.

1. Waste incineration field

Garbage incineration is currently one of the most important application fields of PTFE coated filter bags. The waste incineration process will inevitably produce a large amount of pollutants. These pollutants have the following characteristics:

1). There are particulate matter, acid gases, heavy metals and highly toxic organic pollutants in the flue gas;

2). The flue gas has high moisture content, high dew point temperature, and the filter is easy to condense;

3). Interaction of high and low temperature flue gas;

4). The particles produced by the deacidification treatment are easy to absorb moisture and cause difficulty in cleaning dust and blockage of pipes;

5). The flue gas is highly corrosive.

The filter bag with PTFE as the base fabric and P84 as the surface layer of the needle felt filter material covered by the PTFE microporous membrane can achieve good results in the flue gas purification of waste incineration power plants.

2. The field of coal-fired power plants

Coal-fired power plants are ubiquitous in our country, and the coal combustion process will produce a large amount of sulfur dioxide, nitrogen oxides and inhalable particulate matter. Due to the excellent characteristics of PTFE, the bag filter made of PTFE membrane and glass fiber and other high temperature resistant fiber needled felt composite filter materials can greatly reduce the smoke and dust emissions of power plants in high temperature environments. In addition, the composite filter material of PTFE membrane and glass fiber needled felt is recognized as the most effective material to overcome inhalable particles.

3. Cement industry

As my country's energy conservation and emission reduction requirements become more and more stringent, the traditional electric precipitators used in the cement industry can no longer meet the new national emission standards. In the cement production process, a bag filter made of traditional needle felt composite ePTFE membrane filter material can reduce air pollutant emissions while recycling cement powder, which can increase production, reduce costs and save energy.

4. the field of laboratory purification

In the biological, food, pharmaceutical, and medical industries, where the air cleanliness level is relatively high, the PTFE membrane filter media filter has the characteristics of good stability, corrosion resistance, and large flow under the same resistance conditions, which can meet high efficiency The requirements of air filtration will exert greater application value and economic and technological potential in these industries.
