PPS Dust Filter Bags, High-Temperature Filter Bags, Boiler Dust Collector Bags

PPS dust filter bags are a type of high-temperature filter bags, which are the most commonly used filter bags for boiler dust collectors. They have the characteristics of balanced high-temperature resistance, corrosion resistance and cost-effectiveness, and are widely used in boiler dust removal systems. The detailed introduction is as follows:

 PPS Dust Filter Bags (Core Performance)
PPS (polyphenylene sulfide) dust filter bags are made of PPS fiber through needle felt weaving, which is a medium and high-temperature filter material with mature technology and wide application.

 Key performance: 

1. Temperature resistance: long-term stable operation at 160-180℃, short-term resistance to 200℃, which is suitable for most boiler flue gas temperatures (120-180℃). 

2. Corrosion resistance: good resistance to acid and alkali gases (such as sulfur dioxide, hydrogen chloride), suitable for slightly corrosive flue gas environments of boilers (such as biomass, coal-fired boilers). 

3. Moisture resistance: not easy to absorb moisture, avoiding filter bag blockage caused by high humidity of boiler flue gas.

 4. Dust removal efficiency: ≥99.9%, can capture fine boiler dust (such as fly ash) with particle size ≤1μm. 5. Service life: 2-3 years under normal boiler working conditions, which is longer than ordinary polyester high-temperature bags.

 PPS Bags as High-Temperature Filter Bags
As a typical high-temperature filter bag, PPS bags fill the gap between ordinary polyester bags (≤130℃) and high-temperature PTFE bags (＞200℃). They have the advantages of high-temperature resistance, cost-effectiveness and easy cleaning, and are better than glass fiber bags (poor toughness) in terms of toughness. They are widely used in high-temperature dust removal occasions with temperature 130-200℃, such as boilers, metallurgy, chemical industry, etc.

Application of PPS Bags in Boiler Dust Collectors
PPS bags are the first choice for boiler dust collector bags, especially for biomass boilers, coal-fired boilers and waste incineration boilers. 

The reasons are as follows: 

1. Match boiler flue gas characteristics: adapt to high temperature (120-180℃), high humidity (≥70%) and slight corrosion of boiler flue gas, avoiding bag damage and failure.

 2. High dust removal efficiency: meet the strict emission standards of boiler dust (≤30mg/m³). 

3. Cost-effectiveness: the price is lower than PTFE and FMS bags, and the service life is long, reducing the operating cost of boiler dust collectors.

 4. Easy maintenance: good air permeability, easy to clean, and convenient for daily replacement and maintenance.
