In chemical plants, due to the presence of special environments such as high temperatures, corrosive gases, and particulate matter, it is necessary to choose high-temperature resistant dust removal filter bags to ensure efficient dust removal and safe operation. The following are common high-temperature resistant dust removal filter bag materials:
P84 (polyamide fiber): It has good high-temperature resistance and can withstand working temperatures up to 260 ℃. It has good chemical corrosion resistance and tensile strength, and is suitable for high-temperature dust removal processes in chemical plants.
PTFE (polytetrafluoroethylene): It has excellent high-temperature resistance, can withstand working temperatures up to 260 ℃, and has good chemical corrosion resistance and extremely low surface friction coefficient, suitable for dust removal scenarios of high temperature and corrosive gases.
High temperature resistant glass fiber cloth bag: Made of special high-temperature glass fiber material, it can withstand work in high temperature environments, and the general temperature resistance range can reach around 250 ℃.
These high-temperature resistant dust removal filter bags can effectively filter solid particles in high-temperature gases and maintain a long service life.
However, when selecting and using high-temperature dust removal filter bags, other factors need to be considered, such as gas composition, particle properties, pressure loss, etc., to ensure the selection of appropriate filter bag materials and sizes, and to install and maintain them in accordance with relevant specifications and operational requirements.
