Application Fields of PPS Dust Filter Bags
Due to the excellent performance characteristics of PPS dust filter bags, they are widely used in many industries, playing a crucial role.
Power Industry
- Coal-Fired Power Plants: The flue gas generated during coal combustion usually has a temperature range of 140 – 180°C and contains a large amount of acidic gases such as SO₂ and NOx, as well as dust. PPS dust filter bags can operate stably in such high-temperature and highly corrosive environments, effectively filtering dust and resisting the erosion of acidic gases. According to statistics, after a large coal-fired power plant adopted PPS filter bags, the dust emission concentration decreased from 50mg/m³ to below 10mg/m³, significantly improving environmental benefits, ensuring that the flue gas meets the emission standards, and meeting the increasingly stringent environmental protection requirements.
- Waste Incineration Power Generation: The flue gas generated by waste incineration has a complex composition, containing not only highly corrosive gases such as HCl and SO₂ but also pollutants like dioxins and heavy metals, with a large temperature fluctuation range (120 – 200°C). PPS filter bags, with their high-temperature resistance and chemical corrosion resistance, can efficiently intercept dust and pollutants while withstanding frequent temperature changes, ensuring the stable operation and environmental compliance of the waste incineration power generation system, and providing strong support for the sustainable development of the waste incineration power generation industry.
Steel Industry
In the steel production process, such as in blast furnace ironmaking, converter steelmaking, and other processes, a large amount of high-temperature dust and waste gas are generated. These waste gases contain a large number of dust particles and harmful gases such as CO and SO₂. PPS dust filter bags can efficiently remove dust particles in an environment with high temperature, high dust concentration, and corrosive gases, reduce the flue dust emission concentration, and minimize air pollution. At the same time, they protect production equipment, extend its service life, and improve production efficiency.
Chemical Smelting Industry
In chemical production processes such as smelting, petrochemicals, and coking, the flue gas often contains high concentrations of acidic gases (such as sulfuric acid mist, hydrochloric acid gas), organic pollutants, and high-temperature dust. For example, in metallurgical processes such as copper and zinc smelting, PPS dust filter bags can effectively filter dust containing heavy metals and resist the corrosion of sulfides in the flue gas. In chemical production, many reaction processes generate corrosive waste gases. The chemical corrosion resistance of PPS filter bags enables them to adapt to these harsh working conditions, operate stably, and achieve efficient dust removal, providing reliable guarantee for environmentally friendly production in the chemical smelting industry.
Building Materials and Cement Industry
The flue gas emitted from the kiln head and kiln tail of cement plants has a high temperature (150 – 200°C) and contains alkaline dust and a small amount of acidic gases. PPS filter bags can adapt to high-temperature environments and resist the abrasion of alkaline dust and the corrosion of acidic gases. In the cement production process, stable ventilation and efficient dust removal are crucial for ensuring product quality and production efficiency. PPS dust filter bags can efficiently filter dust, maintain stable ventilation during cement production, improve production efficiency, and meet environmental protection requirements, helping the building materials and cement industry achieve green production.
Other Industries
In addition to the above main industries, PPS dust filter bags are also widely used in industries such as glass manufacturing, ceramic production, and biomass power generation. In the glass manufacturing process, the flue gas generated by high-temperature furnaces contains dust and some volatile substances, and PPS filter bags can effectively purify the flue gas. In the ceramic industry, a large amount of flue gas and dust generated during the firing process can also be treated by PPS dust filter bags. In biomass power generation, the flue gas contains many fine particles and some corrosive components. PPS filter bags can effectively remove particles and resist a certain degree of corrosion, ensuring the environmental protection of the biomass power generation process.
