VOLKOV'S CAVITATION AERATOR Russian patent published in 2020 - IPC B01F5/02 B01F3/04 C02F1/74 

FIELD: technological processes.

SUBSTANCE: cavitation aerator of Volkov is designed for high-efficiency aeration of liquid homogeneous and heterogeneous media with application of cavitation effect, essentially accelerating both physical heat-mass exchange processes and complicated by chemical reactions. Device for aeration of liquid includes a housing with a liquid supply channel, an air supply channel and a liquid and air mixture discharge channel, wherein liquid is supplied under pressure into a hollow-cavity nozzle installed in the housing with a swirler inside it with helical cutting of channels on its outer surface, in the zone of outlet of the conical flame of the liquid flow from the hole of the nozzle conical part a baffle plate is installed, cavitation on which fluid flow accrues cavitation occurs, air is supplied to inner zone of liquid flow torch via channel in baffle and through hole therein. Due to the fact that active medium of formation of interphase surface is liquid phase area of contact of phases increases significantly, transfer processes are determined not only by molecular diffusion, but also accelerated by phase turbulization.

EFFECT: invention can be used for the processes of deferrigation of water, acceleration of waste water treatment processes.
