High temperature filter bags are filtration devices specifically designed for high - temperature environments. They are made of high - temperature - resistant materials such as glass fiber and aramid, which can withstand temperatures of 200 °C or even higher. These filter bags have high - efficiency filtration performance and can accurately intercept dust particles at the micron level. With strong chemical stability, they remain stable in complex chemical environments such as acidic and alkaline conditions. They ensure a clean production environment during the treatment of high - temperature flue gas and exhaust gas.

Operating Temperature: Glass fiber filter bags can withstand high temperatures ranging from 200 - 300 °C for a long term, making them suitable for filtering high - temperature flue gas in some cement kilns and steel plants.
Chemical Compatibility: In the filtration of high - temperature reaction tail gas in the chemical industry, if the tail gas contains strong acid or strong base components, it is necessary to select filter bag materials with good acid and alkali resistance, such as PTFE.
Mechanical Properties: In some high - pressure and high - velocity high - temperature gas filtration scenarios, filter bags need to have high tensile and tear resistance to prevent rupture during use. For example, in the intake air filtration of gas turbines.
