Advances in research on granular bed filter for dust removal
摘要
Abstract
The development and application of high temperature gas dust removal technology makes great sense to the energy utilization and cleaner production in industrial processes. Granular filtration technology which shows a balance between efficiency and pressure drop,better economy and good adaptability in harsh environment,has provided an effective way to settle issues involved in efficient synthetically utilization of solid fuels,clean electricity generation and utilization of residual heat,etc. The principle and forms of granular bed filters(GBFs)were introduced in this paper. Special emphasis was placed on the structure type and improvement research of GBFs,including fixed GBFs,moving GBFs and other forms of GBFs. The influence factors and present studies on engineering application of GBFs were then summarized,and the development trend of GBFs was discussed at last. There are many control factors in moving GBFs and the filtration efficiency of moving GBFs still needs to be improved compared with fixed GBFs,but moving GBFs are more appropriate for industrial application and are the first choice,because moving GBFs can be operated continuously at a steady efficiency and pressure drop. In addition,uniform flow and high utilization efficiency of granular layer,optimization of dirty gas inlet modes and pertinency and integration design are the future directions of research for moving GBFs.关键词
