PPS dust filter bag
Detailed introduction

Introduction of PPS dust filter bag:
The special filter material for bag dust removal of coal-fired boilers (HAT series of PPS filter materials) was developed by Shandong Aobo Environmental Protection Technology Co., Ltd. on the basis of the 863 project dry removal of multi-pollutant coordinated control technology for coal-fired power plants. Fiber needle felt filter. It has the characteristics of high dust removal efficiency and low smoke resistance. The filter material has the characteristics of high filtration accuracy, low emission and stable performance. The high-quality PPS fiber imported from Japan is used to card the woven fabric through a complete set of domestic needling equipment, and then processed into high-temperature setting, surface calendering treatment, high-concentration PTFE impregnation, anti-corrosion, and water- and oil-repellent treatment.
Filter bag longitudinal, bag mouth and bag bottom using Japanese heavy machine sewing equipment, PTFE thread sewing. The filter bag mouth is made of stainless steel elastic ring. 100mm double-layer reinforcement at the bottom of the bag.
Product Features:
Advantages: PPS fiber has good corrosion resistance and hydrolysis resistance. It is currently a high cost-effective filter material for coal-fired boilers.
Disadvantages: Not resistant to oxidation. It is required that the oxygen content in the actual working conditions should be less than 8% (150 ° C). The higher the temperature, the lower the oxygen content. For every 10 ° C increase in temperature, the chemical reaction doubles.
Implementation standards:
1. Technical requirements for environmental protection products-bag filter bag HJ / T327-2006
2.Technical requirements of bag dust collector GB / T6719-2009
3. Air pollutant emission standards for thermal power plants GB13223-2011
4. Air Pollutant Discharge Standard for Domestic Waste Incineration DB11502-2008
Application:
1. Bag dust collector for coal-fired boiler
2. Semi-dry and dry desulfurization bag filter (power plant, steel plant sintering machine)
3.Bag dust collector for biomass power generation
4. Waste incineration power generation (fluidized bed boiler)
5. Arsenic collection system for gold smelting
6, smelter matte drying system
7.Kaolin dust removal system
