Research Progress on the Dust Cleaning of Bag Filter

The bag filter becomes one of the most effective equipments for dust control in coal fired boilers, and its long-term stable operation depends on the technology of dust cleaning. There are many aspects which are always conflicted and changeable influence the efficiency of the dust cleaning. The mainly purpose of this paper is to make the analysis and comparison of the latest research on the dust cleaning of the bag filter in the following aspects:dust cleaning mechanism, infection factors, experiments and numerical simulation of its process. Hence, some conclusions are given for the improvement of the efficiency of dust cleaning and optimization design of bag filter system.
