Filtration systems of aspiration, ventilation and pneumatic transport in industry: features of operation, aerodynamic problems and ways to solve them

Filtration equipment is used in the industry according to the following directions: in aspiration systems, in the final phase of transportation of pneumatic transport systems to separate solid components from the transporting medium; in supply and exhaust ventilation systems. A review of the development of various designs of filtration equipment and the peculiarities of its operation in accordance with the indicated directions of use is considered. Attention is paid to the issues of aerodynamics of work processes in systems, approaches to improving the conditions of the flow of work processes are analyzed in order to increase the efficiency and reliability of system operation. Ways to solve a general problem that has not yet been resolved, typical for supply and exhaust ventilation devices - the problem of ensuring uniform distribution of the medium in branched distribution and flow collection systems are proposed. This applies to both constructive measures and the use of automatic process control tools.
