DEAERATION TOWER Russian patent published in 2009 - IPC C02F1/20 B01D19/00 

FIELD: engines and pumps, chemistry.

SUBSTANCE: deaeration tower comprises an accumulating tank with a branch pipe intended for sucking off non-condensing gases and a column fitted above the said tower and representing water-jet ejector with water-feed device made up of a set centrifugal jets fitted regularly over the column cross and a steam-feed circular manifold connected to the aforesaid column by radial crossbars. A taper-like entrainment separator is arranged on the column outlet. Note that the column is divided by vertical partitions into sections consecutively interconnected along the steam-gas path by the separator. Mind that the column consists of at least two units connected in parallel along the steam and discharged gas paths. Each of the centrifugal jets incorporates housing with a chamber wherein an auger is press-fitted. Note also here that the housing bottom has a throttling orifice while the housing top part accommodates a union provided with a cylindrical bore, a diffuser and a gasket. The said auger inner part has a threaded hole, the direction of the thread of the said hole being aligned with the auger outer thread direction. Note also that a mixing taper chamber is fitted above the throttling orifice to form a total finely dispersed swirling flow.

EFFECT: higher efficiency and quality.
