摘要
主要对颗粒层过滤除尘的过滤机理以及国内外移动床颗粒过滤器的高温除尘技术情况进行了综述,介绍了颗粒层过滤效率和系统压力降的计算方法,并对今后颗粒层过滤技术的发展提出了一些建议。
The filtration mechanism of granular bed and the high - temperature dust removing technology of internal and overseas moving granular bed filter are reviewed in the paper. In addition, the method to calculate the filtration efficiency of granular bed and pressure drop is introduced. At last, we put forward some views on the development of technology in future.
