DEVICE FOR CREATING GAS-LIQUID FLOW, METHOD AND SYSTEM FOR DISSOLVING GAS IN LIQUID Russian patent published in 2024 - IPC C02F3/20 B01F23/23 

FIELD: various technological processes.

SUBSTANCE: group of inventions relates to methods and devices for dissolving gases in liquids and can be used, in particular, for dissolving air oxygen in water during treatment of domestic and industrial waste water. System for dissolving gas in a liquid comprises in-series connected a liquid supply unit, at least one device for creating a gas-liquid flow, located above the surface of the volume of liquid in which the gas is dissolved, and at least one turbine located in the bottom area of the liquid volume. Device for creating a gas-liquid flow comprises nozzle, working chamber, ejector chamber and diffuser, all being connected in series to make a single cylindrical housing. Nozzle consists of confuser and cavitator. At the beginning of the ejector chamber there are support posts with openings for gas supply along the external surface of the liquid flow. In cavitator there are channels for suction of gas flow from external medium and its supply inside liquid flow. Nozzle is made with possibility to create gas-liquid flow and is characterized by a flow coefficient of not less than 0.9.

EFFECT: increased energy efficiency of gas dissolution in liquid.
