The article deals with topical issues related to the need to improve the efficiency of dust collection systems, the correct choice of the method of purification of emissions and the design of industrial filters linking the operating modes of devices with the properties of the captured dust. A method of complex treatment of emissions with a wet dust collector built into the process line is proposed.
