DEAERATION COLUMN Russian patent published in 2012 - IPC C02F1/20 

FIELD: process engineering.

SUBSTANCE: invention relates to heat exchange hardware and may be used as deaeration device in heating feed water and removing corrosive gases therefrom in water treatment system. Proposed column comprises casing with steam and feed water inlet branch pipes, and vented steam and deaerated water discharge branch pipes. said case accommodates jet and bubbling devices arranged one above the other and water distribution manifold penetrated by bypass tubes. Jet device made up of taped funnel serves to collect steam and is arranged axially symmetric with column case. Bubbling device consists of two equidistant perforated sheets with ordered load arranged there between. Every said bypass tube of aforesaid manifold is provided with holes regularly spaced apart over bypass tube cross-section and arranged along screw line with respect to bypass pipe generatrix. Bypass pipe inner surface has screw groove made all along its height. Water distributing manifold inner chamber communicated via pipeline with feed water supply branch pipe, both being arranged above bubbling device.

EFFECT: safe removal of corrosive gases, higher reliability.
