Title (EN) DISTILLATION APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE DISTILLATION
Abstract:
(EN) A distillation apparatus includes an evaporator-condenser heat exchanger in combination with a compressor. The heat exchanger is mounted to float in an at least partially immersed position in a sump of liquid. The liquid may be a sap, or may be soiled water, and may have suspended solid. Heating of the liquid yield steam, the steam is compressed, and the heated, compressed steam is fed back into the heat exchanger to provide further heat to the liquid. The process yields a concentrated in the liquid bath and distilled water, each of which may be a desired product. The system may include a pre-heater that exchanges residual heat from the hot distillate with the cooler input liquid. The apparatuws and process may have multiple stages.
(FR) L'invention concerne un appareil de distillation comprenant un échangeur de chaleur évaporateur-condenseur en combinaison avec un compresseur. L'échangeur de chaleur est monté pour flotter dans une position au moins partiellement immergée dans un puisard de liquide. Le liquide peut être une sève, ou peut être de l'eau souillée, et peut avoir un solide en suspension. Le chauffage du liquide produit de la vapeur, la vapeur est comprimée, et la vapeur comprimée chauffée est renvoyée dans l'échangeur de chaleur pour fournir de la chaleur supplémentaire au liquide. Le procédé permet d'obtenir une solution concentrée dans le bain liquide et de l'eau distillée, chacune d'entre elles pouvant être un produit souhaité. Le système peut comprendre un pré-réchauffeur qui échange la chaleur résiduelle du distillat chaud avec le liquide d'entrée du refroidisseur. Les appareils et le procédé peuvent avoir de multiples étages.
