DEVICE FOR STORAGE AND DELIVERY OF CRYOGENIC PRODUCTS Russian patent published in 2001 - IPC

FIELD: cryogenic engineering; storage and delivery of cryogenic products to consumers; transportation of cryogenic products in reservoirs by different kinds of transport. SUBSTANCE: proposed has heat-insulated reservoir secured in vacuum-tight casing, drain and filling pipe lines fitted with shut-off valves connected with coupling pipe line in sections between casing and shut-off valves; coupling pipe line includes heat exchanger-evaporator and fittings; bleeding-off pipe line provided with shut-off valve is connected to coupling pipe line after heat exchanger-evaporator; secured at end of drain pipe line inside reservoir is collector made in form of circular perpendicular perforated whose interior is connected with drain pipe line by means of radial pipe lines. Reservoir is provided with float made from heat-conducting material and fitted at smooth circular clearance between inner surface of reservoir and end surface of float; flow section area of it is no less than cross-section area of drain pipe or is equal to this area; perforation of collector are located on side directed towards float; surface of collector is provided with limiting projections on this side which are smoothly distributed over it. EFFECT: minimization of time required for raising pressure to working level and losses of product stored in reservoir with open vent. 1 dwg
