METHOD FOR SEPARATING DISSOLVED GASES FROM PUMPED FLUID AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2017 - IPC B01D19/00 C02F1/38 

FIELD: engines and pumps.

SUBSTANCE: separation of dissolved gases from the pumped fluid by the method of decreasing the pressure in the gas flow using the phenomenon of cavitation is performed by feeding liquid through the inlet branch pipe to the diametric disk rotor, dividing the fluid flow by centrifugal forces in the interdisk space into regions with increased and decreased pressure, and separate discharging the fluid and the separated gas through branch pipes. In the interdisk space of the rotor, due to a pressure drop from the rotor axis to the periphery, an adjustable cavitation region of decreased pressure is created, the size of which in the radial direction depends on the rotor speed and is proportional to the square of the speed, while the separated gas is forced out through the central hollow channel. The central hollow channel of the disk rotor for gas removal is made in the form of a tube with perforated walls or is formed by a package of discs with central holes and is connected in the lower part with a gas forced removal branch pipe, and in the upper part with the last solid disk of the rotor and the engine shaft.

EFFECT: invention allows to combine the function of the transfer pump and the device for removing dissolved gases from the pumped fluid and provides the possibility of changing the fluid treatment conditions.
