Abstract Flow field characteristics are the key factors affecting the purification effect, dust removal efficiency and service life of bag filter, and are the basis for optimizing or evaluating the rationality of equipment design. Based on the analysis of the working principle of the bag filter, this paper clarifies the key problems to be solved in the current research and development of the bag filter, expounds the numerical simulation method of the internal flow field of the bag filter, the evaluation index of the flow field characteristics, and the key influencing factors of the flow field distribution, and emphatically summarizes the basic influence law of the common structural design factors on the flow field characteristics of the bag filter. It is hoped that this review can provide reference structural design methods for users to improve the internal flow field performance of bag filter.
