CRYOGENIC FLUID GASIFIER Russian patent published in 1994 - IPC

FIELD: cryogenic engineering. SUBSTANCE: cryogenic liquid gasifier has reservoir for liquefied gas and production evaporator connected with reservoir and with gaseous product supply pipe line. Evaporator is provided with device for blowing off its surface with air which is made in form of working shaft connected with drive and provided with fan impeller on each its end; fan impellers are located respectively opposite first and second units of evaporator. Blowing-off device is provided with pneumatic drive and additional fan impeller with centrifugal orientation of working blades arranged between main impellers which possess axial directivity of working blades. Arrangement of heat exchanger of first unit of evaporator is radial relative to additional impeller; inlet and outlet of the pneumatic drive of blowing-off device are connected respectively to upper portion of reservoir and to gaseous product supply pipe line. EFFECT: enhanced efficiency. 1 dwg
