Abstract
A low temperature vacuum distillation apparatus. The distillation apparatus includes an evaporation section and a condensation section. Fluid flow throughout the system is assisted by an appropriate pump, and heat exchangers, one in each of the evaporation and condensation sections, are interconnected by employment of a heat pump. The condensation section includes a condensation chamber downward from which bubble tubes extend into a collection chamber. Collection chamber is provided with a pump to effect transfer of distillate having volatile impurities entrained therein to a final collection vessel. A pump communicates with vessel to create a partial vacuum therein to ensure venting of the impurities.
Claims8
A vacuum distillation apparatus for purifying a raw liquid, said raw liquid having an impurity of higher vapor pressure than that of a desired distillate component entrained therein, comprising:
- (a) evaporation apparatus including a boiling chamber, means for supplying raw liquid to the boiling chamber, and means for conveying vapor or gas from the boiling chamber;
- and
- (b) condensation apparatus including:
- (i) a closed condensation chamber generally higher than the boiling chamber and communicating with the conveying means to receive, cool, and condense the vapor or gas to a liquid;
- (ii) a first closed collection chamber generally below the condensation chamber;
- (iii) at least one bubble tube sealingly interconnecting a lower portion of the condensation chamber and an upper portion of the first collection chamber and extending downward into the first collection chamber;
- (iv) a second closed collection chamber disposed at a height above a height of said first closed collection chamber;
- (v) first transfer means, sealingly engaged and extending, at one end thereof, into the first collection chamber, and connected, at an opposite end thereof, to said second collection chamber, for conveying a mixture of vapor or gas and distillate component from the first collection chamber to the second collection chamber;
- (vi) means for creating a partial vacuum above a liquid level in said second closed collection chamber sufficient to cause the impurity to become or remain in a gaseous state, yet insufficient to cause the distillate component to change to a gaseous state;
- and
- (vii) means for releasing and venting the impurity.
