<p>Vacuum distillation apparatus (10) for purification of liquids using waste heat including a liquid flow passage (17) connected in series with a supply of liquid for distillation passing through a condensation portion (13) of the distillation apparatus (10), thence passing through a flow restriction (41), a reduced section (42), a degassing chamber (36) and a pump (40). The reduced section (42) includes a throat tap (27) connected to a gas outlet (30) formed on the condensation portion (13) and another throat tap (32) connected to a liquid outlet formed on the evaporator portion (12) of the distillation apparatus (10) whereby non-condensible gases and concentrated liquid are both drawn from the distillation apparatus (10) by the pump (40). There is also provided a liquid inlet (24) connected to the evaporation portion (12) for supplying feed liquid from the degassing chamber (36). The evaporation portion (12) is heated by a waste heat energy supply (16). The purified liquid is drawn from the condensing portion by a pump (34).</p> |
