ABSTRACT:
A plate heat exchanger generally for media liberating a gaseous agent from a liquid heat-transfer medium during heat-exchanging process characterized in that stacks of heat-exchanging plates are placed inside a housing, the interior of this housing being in communication with channels for passing a gaseous heat-transfer medium, whereas each of the heat-exchanging plates has partitions providing a required flow direction for the gaseous agent liberated from the liquid heat-transfer medium and contributing to its discharging from the zones of its liberation disposed at different height of the channel.
The heat exchanger is provided with a device for external passing of the liquid heat-transfer medium between the adjacent heat-exchanging sections 34 and 33 made as a vertical chamber 35 with bubbling elements 36 therein, a union 38 for additional introduction of the gaseous heat-transfer medium being placed in the lower portion of the chamber 35, while the upper portion thereof is provided with a union 40 for gas discharge.
The heat exchanger according to the invention can be effectively used for carrying out heat-exchange processes followed by liberation of a gaseous agent from the liquid heat-transfer medium instead of the pipe heat exchangers traditionally used in the art.
