VACUUM DEAERATOR Russian patent published in 2004 - IPC

FIELD: heat-and-power engineering. SUBSTANCE: the invention presents a vacuum deaerator, that is pertinent to the heat power engineering and can be used, for example, in units of make-up heat and power supply networks The vacuum deaerator contains a housing, a branch-pipe for delivery of the initial overheated water subject to deaeration, a branch-pipe for withdrawal of the deaerated water, a branch-pipe for withdrawal of the gas-vapor mixture, a water distributor of the initial overheated water. The deaerator is supplied with a closed chamber, in the upper part of which there is a distributor of the initial overheated water. At that the chamber has located in its lower part holes to discharge not evaporating water in a cavity of the steam space, and in the upper part the chamber has a steam channel linking the space of steam of the chamber with a space of steam of a cavity of the deaerator. It allows to increase efficiency of deaeration due to multiple expansion of the overheated water. EFFECT: increased efficiency of deaeration. 1 dwg
