<p>PURPOSE:To drive a distillation apparatus by using a heating source with a relatively low temp. and to reduce the capacity of the heating source, by recovering condensation heat of steam generated in an evaporation chamber to utilize the same in order to heat and evaporate water in a diluting section. CONSTITUTION:A condensation chamber is integrated with the evaporation chamber of the diluting section 4 of an absorption type heat pump 1 and another starting heater 50 is provided to said evaporation chamber to utilize it also as a condensation chamber 51. Thereore, in the diluting section, water 32 from the condenser 31 of a concn. section 3 is heated and evaporated in the condensation and evaporation chamber 51 by using steam 14 generated in the evaporation chamber 20 of a sea water desalting apparatus 2 and, at the same time, the vapor 14 is condensed under cooling to obtain fresh water 15. As the result, a distillation apparatus is driven by using a heating source with a relatively low temp., the capacity of the heating source is reduced, and the apparatus can be made compact.</p> |
