Abstract:
1. A dryer for humid compressed gases comprising: a pressure resistant sealed housing; a plate-type heat exchanger disposed in said housing, said plate type heat exchanger having a heat recovery section and a cooling section that are comprised of a plurality of stacked plates that are sealed relative to each other in a gas-tight manner, said heat recovery section including an inflow port and said cooling section including an outflow port; and a condensate separator positioned in said housing so as to intercept cool compressed air circulating inside said housing from said outflow port of said cooling section to said inflow port of said heat recovery section, wherein adjacent stacked plates define channels therebetween for two or more fluids to be guided therethrough in a heat-exchange relation such that a direction of the fluid in adjacent ones of the channels are opposite to one another, wherein each of said stacked plates includes at least one aperture that is mutually aligned with an aperture of an adjacent stacked plate so as to form a fluid conduit that extends through said plate-type heat exchanger in fluid communication with said channels, and wherein said dryer is configured such that compressed gases exit said cooling section and said heat recovery section of said heat exchanger into said housing and then pass through said condensate separator.
