Product description

High Filtration Efficiency PPS Bag Filters With PTFE Membrane For Dust Collection
Overview:
Our company can offer all kinds of high filtration efficiency PPS bag filters with PTFE membrane used in baghouse. Our PPS modified filter felt cloth is developed for the characteristics of high temperature flue gas dedusting of large coal-fired boilers.

PPS fiber can be used under a temperature below 190℃. It has good acid and alkali resistance. Its shortcoming is bad oxidation tolerance. The allow oxygen content is related with the application temperature.

These high efficiency filter bags have excellent acid and alkali resistance and good hydrolysis resistance, and they only degrade in strong oxidants. PPS bags have the strength of complete retention and inherent chemical resistance, which can maintain good filtration performance in harsh environments to achieve the desired service life.

Oxidizing Agents fair

PPS is degraded by strong oxidizing agents such as O2 NOX, SOX, Br2. The recommended operating temperatures stated above are for environments which do not include these oxidizing agents. The inclusion of these oxidizing agents in the operating environment in elevated concentrations lowers the recommended operating temperature below that stated above. The inclusion of the PTFE scrim can extend life of the media in those extreme chemical conditions.


Features:

1. High efficiency filter bags have good temperature resistance, and the maximum operating temperature can reach 230 °C;

2. This filter bag has strong dust collection ability. Because of the large surface area, large pores and small pore size of the fiber, the filter material has strong trapping and intercepting ability for dust, especially for the collection of ultrafine dust.

3. It has good oxidation resistance. PPS fiber has good hydrolysis resistance, acid resistance and alkali resistance.

4. High efficiency filter bags are resistant to high filtration load. When designing and producing the filter material, we chose PPS filament base fabric, and after two high-temperature setting, the strength was further improved. The filter material air cloth ratio can meet the design requirements of large coal-fired furnace bag type dust collector.


Application:

It is commonly used in pulse dust cleaning type dust collectors such as filter coal boilers, garbage incinerators, and dust collection of power plant fly ash.


Our advantages:
Our company established in 1997, and we have plenty of production experience.
We have successfully passed the ISO9000 international quailty management and the certificate of RoHS.
Our products not noly sell well in domestic market and exported to all over the word because of the excellent quality and professional service.
