DEAERATOR Russian patent published in 2010 - IPC C02F1/20 

FIELD: heating.

SUBSTANCE: invention refers to heat engineering and is intended for being used during make-up water heating and corrosion-aggressive gases removal from it in water treatment system of nuclear power station. Deaerator includes housing with water and steam inlet connection pipes, vented steam and deaerated water outlet connection pipes, jet and bubble plates located one below the other, confuser arranged in lower part of the housing, vented steam outlet pipeline installed along housing axis and connected to vented steam outlet connection pipe in lower part of the housing, a head piece. The head piece is made of concentrically located grids fixed on edges in radial direction with rings-inserts having holes, and the sheet rigidly attaching the head piece to the housing. Holes of upper rings-inserts are equipped with overflow tubes connected to the sheet and forming a distributing chamber between them. Deaerator is also equipped with heating chamber with single-coil swirler, which is arranged coaxially to vented steam outlet pipeline and head piece; at that, cavity of heating chamber is interconnected with water inlet connection pipe on one side and cavity of distributing chamber on the other.

EFFECT: increasing efficiency of gas removal from make-up water at operation with increased pressures.
