SIZING OF A DEDUSTING SYSTEM

One of the main problems present in almost all industrial processes that involve the handling and treatment of bulk solids is the generation and emission of airborne dust, which must be maintained within the limits imposed by the law. Among the most frequently adopted dedusting systems, a particularly important role is played by textile filters, which are generally utilised in the form of bag filters, pocket filters, panels, and so on. This article analyses the criteria adopted for correct sizing of such devices. The initial section, containing a brief theoretical analysis of the mechanisms involved in the filtration process on which the characteristic dimensions of the system depend, is followed by a series of analytical reports with discussions, chosen for their potential usefulness in the design of a dust filter. In closing, the article presents an analysis of the results of tests conducted at the laboratories of SRMP srl, aimed at evaluating the performance of cleanable dust filters.
