DEVICE AND METHOD FOR OBTAINMENT OF GAS BUBBLES IN LIQUID Russian patent published in 2023 - IPC B01F23/20 

FIELD: water purification.

SUBSTANCE: group of inventions relates to a device and a method for obtainment of gas bubbles in liquid; it can be used in the field of water purification. The device contains at least one rotating gas-permeable hollow shaft located in at least one container. On the hollow shaft, in a sealed contact with each other, aeration discs and separators are alternately located. The device also contains at least one supplying pipeline for at least one compressed gas. At the same time, each of separators contains at least one centered hole for accommodation of the hollow shaft and at least two chambers. In this case, at least two chambers are located around the centered hole and equidistant from it. At the same time, the centered hole and at least two chambers at least partially coincide, and they are in open communication with each other in the area of coincidence, so that compressed gas from the hollow shaft can be supplied, respectively, to at least one of separator chambers and can be supplied from at least one separator chamber to aeration discs.

EFFECT: provision of uniform formation of bubbles in liquid.
