CRYOGENIC LIQUID GASIFIER Russian patent published in 2003 - IPC

FIELD: equipment to discharge liquefied or solidified gases from vessels with change of state. SUBSTANCE: gasifier comprises tank for cryogenic liquid having feeding pipeline, drainage pipeline and distribution pipeline for cryogenic liquid supplying to gasifying device. Pipelines are equipped with remote control shutoff valves. Gasifier has automatic control system for valves regulating. Drainage and distribution pipelines formed as rigid pipelines are connected such that temperature variation results in displacement of pipeline free ends. Pipeline free ends are joined by mechanical connection means with switches of automatic valve control system. Gasifier comprises additional tank for cryogenic liquid. Mechanical connection means may be flexible. Thermally conducted fins may be formed on pipeline outer surfaces. Flow regulator may be arranged at gasifying device inlet. EFFECT: reduced cost and maintenance charges, increased pressure of resultant cryogenic gases, improved reliability, possibility of operation automation. 5 cl, 6 dwg, 2 tbl
