DEAERATOR Russian patent published in 2014 - IPC C02F1/20 B01D19/00 B05B1/34 

FIELD: power industry.

SUBSTANCE: invention relates to thermal deaeration of liquid and can be used for removal of non-condensing gases, mainly oxygen and free carbonic acid from feed water of a steam-turbine plant. A deaerator for feed water of the turbine plant includes storage tank 1 with non-condensing gas exhaust branch pipe, column 2 in the form of a water-jet ejector, a water supply device made in the form of centrifugal atomisers 3 fixed on pipelines 4, and steam supply header 5. Cone-shaped mist eliminator 7 is installed in storage tank 1 at the outlet of column 2. Each of centrifugal atomisers 3 includes a hollow body with a nozzle and a central core. The atomiser body includes a coaxial bushing rigidly attached to it with a nozzle fixed in its lower part.

EFFECT: invention allows reducing hydraulic resistance and increasing liquid atomisation degree.
