MULTI-STAGE BUBBLE COLUMN HUMIDIFIER Russian patent published in 2018 - IPC B01D1/14 C02F1/04 B01D19/00 

FIELD: technological processes.

SUBSTANCE: invention relates to desalination plants. Feed liquid flows into a second-stage humidifier chamber to form a second-stage humidifier bath. First remnant of the feed liquid from the second-stage humidifier chamber then flows into a first-stage humidifier chamber to form a first-stage humidifier bath having a temperature lower than that of the second-stage bath. Second remnant of the feed liquid is then removed from the first-stage humidifier. Meanwhile, a carrier gas is injected into and bubbled through the first-stage humidifier bath, collecting a vaporizable component in vapor form from the first remnant of the feed liquid to partially humidify the carrier gas. Partially humidified carrier gas is then bubbled through the second-stage humidifier bath, where the carrier gas collects more of the vaporized component from the feed liquid to further humidify the carrier gas before removal from the second-stage humidifier chamber.

EFFECT: desalination plant was proposed.
