Advantages of granular filters with a connected layer structure over alternative means of ultrafine fine removal of mechanical impurities from gaseous process media are examined.
Specific structural solutions for these vessels, and their operating parameters in the production of electronic devices, in biotechnology, during the production of electrolytic hydrogen, and in cryogenic engineering are presented. Methods are recommended for regeneration of multilayer filtering structures. Information on commercial and socioeconomic prospects of granular filters with a connected layer structure, which are employed for the fine removal of mechanical impurities from gaseous process media, are presented in the bibliography.
