The following are successful application cases of dust filter bags in different industries, demonstrating their efficient dust removal performance and environmental value:

1. Mining industry: efficient control of dust pollution
Iron ore crushing section: a large mining enterprise in the crushing and screening links to introduce cloth bag dust collector, through the needle felt filter bag to capture fine dust, dust emission concentration is reduced to the national standard, improve the working environment, reduce the risk of occupational diseases.
Gold mine tailings treatment: gold mine enterprises use customized filter bags to treat the dust in the tailings transportation, combined with the pulse ash cleaning system, dust capture rate of more than 99%, effectively protect the surrounding ecological environment, enhance the enterprise environmental protection image.
2. High temperature industry: cope with complex conditions
Glass manufacturing: A glass factory uses coated PTFE needled felt filter bags to treat high temperature flue gas (260 ° C), which not only achieves dust emission concentration below 10mg/m³, but also reduces the filter bag replacement frequency and reduces maintenance costs by 30%.
Coal-fired boiler: A power plant uses aramid based filter bag, stable operation in high temperature and high humidity environment, PM2.5 capture efficiency of 99.99%, helping to achieve ultra-low emission goal.
3. Building materials and chemical industry: breaking through technical barriers
Cement factory: Spina felt filter bag developed by a company in Jiangsu improves filtration accuracy through high-pressure water flow process, reducing dust emission from 50mg/m³ to less than 10mg/m³, and increasing material utilization rate by 20%, breaking foreign technology monopoly.
Chemical reactor: A chemical plant uses PTFE coated filter bags to treat the tail gas containing corrosive gases, and the filter bag life is extended to more than 3 years, while achieving efficient recovery of catalyst powder.
4. Agriculture and people’s livelihood: Meet the needs of special scenarios
Straw crushing: The cloth bag energy-saving vacuum cleaner developed by Zhoukou enterprises is applied to the peanut seedling crushing equipment, which completely solves the problem of dust pollution, has been certified by the national patent, and is called “dust removal magic weapon” by farmers.
Cigarette production: A cigarette factory in Chongqing has extended the replacement cycle of the filter bag by 50% by reforming the anti-clogging device of the pressure differential meter pressure tube combined with the anti-corrosion filter bag, and the transformation cost of a single set of equipment is only 8 yuan.
5. Environmental technology innovation: intelligent upgrade
Quarry comprehensive application: A quarry in the crushing, screening, transportation links to deploy intelligent bag dust removal system, real-time monitoring of filter bag status through the pressure sensor, combined with AI algorithm to optimize the cleaning cycle, dust concentration reduced by 80%, equipment operating efficiency increased by 25%.
Circular economy practice: An environmental protection company in Xiamen developed a high-temperature silicone sealing process, which increased the service life of the filter bag to 4 years, successfully applied to a number of large projects at home and abroad (such as Turkey waste incineration plant), and the material loss rate was reduced from 2% to 1%.
Sum up
Through material innovation (such as PTFE, arnylon, spina felt) and intelligent design, dust filter bags have achieved significant results in mining, electric power, chemical industry, agriculture and other fields, not only to meet the requirements of environmental regulations, but also to reduce costs and increase efficiency for enterprises. In the future, with the development of filter bag technology in the direction of high precision, long life and intelligence, its application scenarios will be further expanded to help achieve the goal of global carbon neutrality.
