Abstract
A distillation apparatus is disclosed herein. The distillation apparatus comprises an evaporation chamber, a heat source arranged to provide heat to the evaporation chamber, one or more condensing chambers located at least partially inside the evaporation chamber, a fluid inlet connected to the evaporation chamber, one or more fluid outlets attached to the one or more condensing chambers and a vapour compressor pump. Also disclosed is a liquid ring pump suitable for use with such a distillation apparatus, the pump comprising a pump body, a pump compression chamber provided within the pump body, a rotor mounted within the compression chamber, a rotor axle to mount said rotor, the rotor being provided with one or more ceramic bearings to mount it to the rotor axle.
Claims11
A distillation apparatus comprising:
- an evaporation chamber;
- a fluid inlet connected to the evaporation chamber and for supplying liquid to be distilled to the evaporation chamber;
- a heat source arranged to provide heat to the liquid in the evaporation chamber so as to evaporate the liquid in the evaporation chamber,
- a condensing chamber,
- one or more condenser fluid outlets attached to the condensing chamber;
- a vapour compressor pump;
- a vapour inlet;
- a periscope breather connecting a head space of the evaporation chamber with the vapour compressor pump;
- a pump outlet;
- and
- a vapour outlet pipe which connects the pump outlet to the condensing chamber,
- wherein
- (i) the condensing chamber is located partially or wholly within the evaporation chamber;
- or
- (ii) the evaporation chamber is located within the condensing chamber, and
- the vapour compressor pump is at least one of located below the condensing chamber or positioned equal to or below a maintained head of the distillate in the condensing chamber, such that, in use, distillate from the condensing chamber falls into the vapour compressor pump under the action of gravity so as to maintain the vapour compressor pump in a primed state.
