Abstract: North Caucasian Institute of Mining and Metallurgy (State Technological University) has developed a design of a jet bubbler which is based on the patented design of the device main unit – a distribution plate, which allows to implement a foam mode in the bubbler. This dust collector allows you to capture small dust particles (<1 microns), including nanoparticles, that are not captured in bag filters. The article presents a method for calculating the hydraulic resistance of the bubbler, which is required for use, when selecting a fan for the process of dust collection in the bubbler. The hydraulic resistance of the bubbler is defined as the sum of the components: the static pressure of the liquid layer, the capillary drop in the zone of bubbles formation and the resistances of distribution plate parts. The developed method was used in the design of a process line for cleaning gases from pulverized ascents of waelz kiln of zinc production containing nanoparticles.

Keywords: hydraulic resistance, bubbler, bubbles, nanoparticles, capillary drop, surface tension
