METHOD AND EQUIPMENT FOR CONDENSATION, FOR RETREATMENT SYSTEMS Russian patent published in 2010 - IPC B09B3/00 

FIELD: process engineering.

SUBSTANCE: set of invention relates to method and equipment for cryogenic treatment, for systems of retreatment of various materials, particularly plastic materials integrated with materials of different origin, for example materials produced in retreatment of household equipment, or other hardware, for example refrigerator or the like, and comprises crushing mentioned hardware in grinders to produce composite material accompanied with polluting gas generation, condensing polluting gases by inert coolant. Said inert coolant circulating in gaseous state in said devices is directed into grinding devices. Condensing device comprises housing accommodating heat exchanger representing a double coil with inert coolant inlet and outlet unions. Note here that said housing comprises loading union for condensed mix of air and polluting gas, fresh air inlet union and polluting gas bottom collector.

EFFECT: safe treatment and better ecology.
