EJECTOR MULTISTAGE DEVICE FOR REMOVAL OF GASES FROM WATER Russian patent published in 2024 - IPC C02F1/20 B01D19/00 

FIELD: degassing of liquids.

SUBSTANCE: invention is intended for removal of gases from water. Ejector multistage device comprises a conical converging headpiece with a Venturi nozzle arranged concentrically in a vacuum chamber and entering it, and the vacuum chamber is connected to a number of mixing chambers with air, made in the form of series-connected pipes with increasing diameter and equipped with air supply devices, which form stages of ejection chambers. Vacuum chamber further comprises a conical convergent headpiece with an additional Venturi nozzle and is equipped with a branch pipe with an air inlet control device, wherein the main Venturi nozzle is arranged coaxially and enters the additional Venturi nozzle of the vacuum chamber while the latter enters the first stage of the air suction ejection chamber. Each stage of the ejection chamber is a pipe equipped in the upper part with air suction holes.

EFFECT: reduced consumption of energy spent on removal of gases from water, while maintaining and improving quality of treated water and at the same time high efficiency of the device.
