Does high temperature have a significant impact on dust removal bags?

The influence of high temperature on dust removal bags
Material selection: High temperature flue gas poses higher requirements for the material selection of dust removal bags. In high-temperature environments, some conventional dust removal bags may not be able to withstand the temperature and corrosion of the flue gas, leading to problems such as damage and bag sticking. Therefore, it is crucial to choose materials that are resistant to high temperatures and corrosion.
Filtration efficiency: Dust and harmful substances in high-temperature flue gas may become more active at high temperatures, affecting the filtration efficiency of dust removal bags. To ensure stable filtration efficiency, attention should be paid to the material and structure of the dust removal bag to adapt to different working conditions.
Mechanical strength: High temperature may cause shrinkage, deformation, and even embrittlement of the dust removal bag, reducing its mechanical strength. To ensure safe operation, it is necessary to pay attention to the high temperature resistance and service life of the dust removal cloth bag.
Bag sticking phenomenon: In high temperature environments, some sticky dust or oil fumes may adhere to the surface of the dust removal cloth bag, forming a sticky bag that affects its breathability and filtering effect. To avoid the phenomenon of bag sticking, regular cleaning and maintenance are required.
Measures to deal with the impact of high temperature on dust removal bags:
Choose the appropriate material: For high-temperature environments, dust removal bags made of materials such as PPS (polyphenylene sulfide) or PTFE (polytetrafluoroethylene) with good high-temperature resistance can be selected. These materials have high thermal stability and can adapt to the treatment of high-temperature flue gas.
Optimizing structural design: To improve filtration efficiency and mechanical strength, the structure of the dust removal bag can be optimized. For example, using needle punched felt technology to increase the adhesion between fibers and improve the tensile strength of the fabric bag; Or add a layer of anti-static treatment on the surface of the cloth bag to reduce the adhesion of dust on the surface of the bag.
Strengthen equipment insulation: To reduce the impact of high temperature on dust removal bags, insulation measures for equipment should be strengthened. By designing the insulation layer reasonably and selecting appropriate insulation materials, the impact of flue gas temperature on dust removal bags can be effectively reduced.
Regular inspection and maintenance: To ensure the normal operation of the dust removal bag in a high-temperature environment, its condition should be checked regularly. If any abnormalities are found, they should be replaced in a timely manner. At the same time, regular cleaning and maintenance should be carried out to maintain the good condition of the dust removal bag.
Pay attention to operating standards: When operating the dust collector, it is necessary to strictly follow the operating standards. Avoid prolonged overheating operation to reduce damage to the dust removal bag caused by high temperatures.
Training and Education: Provide training and education to operators to enhance their understanding and maintenance awareness of dust removal equipment. Enable them to operate and maintain the equipment correctly, avoiding damage to the dust removal bag caused by misoperation.
Reasonable selection and configuration: When selecting dust removal equipment, suitable models and configurations should be selected based on actual working conditions. Ensure that the equipment can adapt to the requirements of flue gas treatment in high-temperature environments, while meeting economic and environmental requirements.
