Abstract: Air pollution has attracted increasing attention in recent years. Meanwhile the control of high-temperature industrial smoke/dust has become a social and industry focus because it’s one of the main sources of air pollution. Several technologies used in high temperature smoke/dust control such as electrostatic, bag and electric-bag combined dust removal technology were analyzed in this paper.The current situation and problems of bag type dust removal technology and filter media industry were introduced in terms of raw materials, process, standards and test, basic research, market supervision etc.Some suggestions, were also put forward.

Key words: air pollution; industrial smoke/dust control; high-temperature filter media; high-performance fiber
