In chemical plants, due to the existence of high temperature, corrosive gases and particulates and other special environments, it is necessary to select high temperature resistant dust filter bags to ensure efficient dust removal and safe operation. The following are common high-temperature dust filter bag materials:
P84 (polyamide fiber) : good high temperature resistance, can withstand the working temperature of up to 260℃, has good chemical corrosion resistance and tensile strength, suitable for high temperature dust removal process in chemical plants.
PTFE (polytetrafluoroethylene) : has excellent high temperature resistance, can withstand the working temperature of up to 260℃, and has good chemical corrosion resistance and very low surface friction coefficient, suitable for high temperature and corrosive gas dust removal scenarios.
High temperature glass fiber filter bag: made of special high temperature glass fiber material, can withstand the work in high temperature environment, the general temperature range of up to 250℃. These high temperature resistant dust filter bags can effectively filter solid particles in high temperature gases and maintain a long service life. However, in the selection and use of high-temperature dust 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 in accordance with the relevant specifications and operating requirements for installation and maintenance.
