摘要：

能源、冶金、化工等工业生产中会排放大量高温含尘烟气，而传统高温烟气处理技术存在热能损失、工艺复杂、成本较高等问题。陶瓷纤维膜凭借其孔隙率高、透气性好、耐高温、耐腐蚀等优点，成为高温气体除尘领域的关键材料。低成本开发高强度陶瓷纤维膜成为重点研究方向。本文重点整理了陶瓷纤维膜制备技术（真空抽滤成型、纤维缠绕技术、纺丝技术及模具成型技术）的研究进展，介绍了陶瓷纤维膜除尘机理及性能，并对其发展前景做了分析和研讨。

In energy, metallurgy, chemical industry and other industrial production, a large amount of high-temperature dust-containing flue gas will be emitted, while traditional high-temperature flue gas treatment technology has many problems, such as heat energy loss, complex process and high cost. Ceramic fiber membrane has become a key material in the field of high temperature gas dust removal due to its advantages of high porosity, good air permeability, high temperature resistance and corrosion resistance. The low-cost development of high-strength ceramic fiber membranes has become a key research direction. This paper focuses on the research progress of ceramic fiber membrane preparation technology (vacuum filtration molding, fiber winding technology, spinning technology and mold forming technology), introduces the dust removal mechanism and performance of ceramic fiber membrane, and analyzes its development prospects.
