LIQUID SUPPLY DEVICE Russian patent published in 2021 - IPC B01F3/04 

FIELD: instrument engineering.

SUBSTANCE: invention relates to a liquid supply device containing ultrafine bubbles, used in industry, for example. The liquid supply device includes the trajectory of the flow of liquid supplied from the supply source, and a device for generating ultrafine bubbles that creates nanobubbles in the liquid. The device for generating ultrafine bubbles contains: an exhaust device that releases the liquid taken from the flow path, a gas injection device that increases gas pressure and introduces gas into the liquid released from the exhaust device, and a nozzle for generating nanobubbles in the liquid when the liquid with the injected gas passes through it. The pressure of the liquid entering the exhaust device from the upper side of the flow path relative to the exhaust device is positive, and between the exhaust device and the nozzle for generating nanobubbles using the gas injection device, the gas pressure is increased and gas is injected into the liquid having increased pressure and flowing to the nozzle for generating nanobubbles.

EFFECT: providing the possibility of selecting a liquid containing ultrafine bubbles directly from the flow path for its supply.
