METHOD OF LIQUID DEGASATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC B01D19/00 C02F1/20 

FIELD: food industry.

SUBSTANCE: degasation device contains a chamber (4) for the liquid to be degassed with an aerator (1), injection pipes (2) with spraying holes (3) providing the cavitation effect and the jet formation; air pipes (6) for air supply and removal of discharged gases, made on opposite sides of the chamber (4). The air pipe (6) is equipped with a fan (5) and a hydraulic seal (7). The spraying holes can be in the form of cross-sections of diffuser nozzles. In the chamber (4) of the degassing device, the liquid aeration in the flow is carried out, during which the liquid is saturated with air and cavitation bubbles are created. Thereinafter, hydrodynamic cavitation is carried out by means of reducing the pressure in the liquid flow to a value equal to the pressure of saturated vapours of this liquid at a given temperature or pressure, at which discharging dissolved gases therefrom begins. The discharged gases are vented by air stream with simultaneous mechanical spraying of the liquid as a result of hitting the jet against the wall, which ensures separation and removal of the dissolved gases.

EFFECT: increasing the efficiency of liquid cleaning due to saturation of water with oxygen, oxidation of pollutants, separation of dissolved gases.
