EVAPORATIVE CRYSTALLISER

摘要

FIELD: power industry. ^ SUBSTANCE: ice crystalliser contains cylindrical body with inner cylinder, cavity between them serves for cooling agent delivery and boiling and cavity of while cavity of inner cylinder serves for flow of solution and ice formation. The above cavities do not communicate with each other. In inner cylinder cavity there is shaft with cutters. On outside surface of inner cylinder there is spiral coiling forming helical channel with rectangular cross-section which serves for cooling agent delivery and boiling. ^ EFFECT: this invention allows oil return to compressor without use of auxiliary facilities and periodical shutdown of the unit. ^ 2 dwg
