Abstract
The method of recovering water by vaporizing aqueous solutions employs a heat pump circuit having a compressor, condensor, extention valve and evaporator for a heat transfer medium. The circulation channel for a gas stream which is capable of absorbing water vapor includes a gas washing station into which is sprayed the aqueous solution to be vaporized. The gas stream is guided past the condensor of the heat pump which acts as a heater and the heated gas is delivered into the gas washing station where is absorbs water. The water saturated gas stream is fed past the evaporator which acts as a refrigerating device and the water contents from the gas stream is condensed on the evaporator and returned into a galvanizing bath for example.
