In a new type of evaporator both a stream of cooling liquid and vapor are produced simultaneously. The cooling liquid is then used to compress and condense the vapor in an ejector-condenser. Heat of vaporization is recaptured in the ejector-condenser and recycled back to the evaporator, thus leading

In a new type of evaporator both a stream of cooling liquid and vapor are produced simultaneously. The cooling liquid is then used to compress and condense the vapor in an ejector-condenser. Heat of vaporization is recaptured in the ejector-condenser and recycled back to the evaporator, thus leading to high thermal efficiency.

A distiller including the following: a vertical tube evaporator consisting of a closed evaporator vessel containing an upright heating tube, heating fluid flowing downward inside said heating tube, cooled heating fluid exiting from the bottom of said heating tube, solution in the shell space surrounding said heating tube, feed solution flowing into said shell space, a liquid-vapor interface above said heating tube, a vapor outlet in said evaporator vessel, vapor exiting from said vapor outlet; an ejector-condenser consisting of an intake manifold, a nozzle, a diffuser duct, and a condenser sump with a vapor outlet; said vapor from said evaporator vessel entering said intake manifold; propellant spray from said nozzle containing some of said cooled heating fluid; said propellant spray in combination with said diffuser duct condensing said vapor from said evaporator vessel; hot distillate collecting in said condenser sump; a distillate pump drawing suction from said hot distillate in said condenser sump; some of hot distillate, discharging from said distillate pump, passing through a distillate heater and exiting as said heating fluid; said heating fluid from said distillate heater entering the top of said heating tube.
