<p>PURPOSE:To simplify this device, and to conserve resources while ensuring safety, by storing a condensate in a tank while separating the condensate from gas, and by intermittently returning the condensate stored to a low temperature liquefied gas tank by high pressure gas at the discharge side of a compressor. CONSTITUTION:Liquid condensing on the way of a course sent to a compressor 7 from a low temperature liquefied gas tank 3 is stored in a tank 13 while separating the liquid from gas by means of a gas-liquid separator 12a. When the condensate in the tank 13 increases and reaches fixed value, automatic valves 16, 17 are opened by means of a detecting switch 21, high pressure gas at the discharge side of the compressor 7 is introduced on the surface of the condensate in the tank 13 and the condensate is pressure-sent into the low temperature liquefied gas tank 3. Thus, safety is maintained while simplifying this device because there is no necessity for mounting an evaporating means as seen in conventional devices, and energy can be conserved because pressure at the discharge side of the compressor need not continually be used.</p> |
