In order to meet process requirements or environmental requirements, dust particles in various process gases and flue gases discharged into the atmosphere usually need to be separated directly under high temperature conditions.

High-temperature ceramic fiber filter element can meet the corresponding filtration performance requirements, and has good thermal stability, chemical stability, thermal shock resistance, fracture toughness and light weight. Therefore, it is one of the ideal hot gas filter media.

The work presents a study on the preparation of ceramic fiber filter element, aiming to improve the overall performance of the filter element, so that it can be better applied in the high-temperature gas-solid separation field...
