摘要： PURPOSE:To maintain the evaporated quantity of LNG at the maximum without letting seawater freeze, by detecting the temperature or pressure of a hermetically enclosed medium to keep the stable evaporated state of the LNG without the freezing of the seawater. CONSTITUTION:The pressure of the medium of a heat exchanger 1 is detected by a pressure controller 7. When the seawater in seawater tubes 2 is likely to freeze due to the drop in the pressure of the medium 9, a pressure drop signal is supplied from the controller 7 and a selector 8 sends the signal, with priority, to an automatic valve 6 to reduce the flow rate of LNG to keep the temperature of the medium 9 from dropping, to enable the continuation of evaporation of the LNG. The LNG evaporated by the heat exchanger 1 is heated by a heater 4 and supplied to a user. In this liquefied gas evaporator with the hermetically enclosed medium 9, the temperature of the medium is controlled not to become lower than a prescribed level, so that the seawater which is a heat source is prevented from freezing due to the drop in the temperature of the medium, thus enabling the continuation of the evaporation.
摘要翻译：目的：通过检测密封介质的温度或压力，保持LNG的稳定蒸发状态，不会使海水冻结，从而最大限度地保持LNG的蒸发量，不会使海水冻结。构成：通过压力控制器7检测热交换器1的介质的压力。当海水管2中的海水由于介质9的压力下降而可能冻结时，压降信号从控制器7和选择器8优先地将信号发送到自动阀6，以降低LNG的流量以保持介质9的温度不会下降，以使LNG能够继续蒸发。由热交换器1蒸发的LNG被加热器4加热并供给给用户。在具有密封介质9的液化气体蒸发器中，介质的温度被控制为不低于规定水平，从而防止作为热源的海水由于温度下降而冻结介质，从而能够继续蒸发。

摘要： PURPOSE:To prevent the destruction of a concrete layer due to thermal stress without requiring to dig the ground deeply and with a thin wall in thickness by burying a cylindrical tank proper comprised of the concrete layer, a heater, a cold reserving layer, and a film layer in parallel to the earth surface. CONSTITUTION:A low temperature tank 1 is provided with a cylindrical tank proper 2 with both ends closed, and the tank proper 2 is horizontally buried under the ground so that its axial direction is nearly in parallel to the earth surface. A lead pipe 3 feeding or discharging a low temperature liquid is provided on the tank proper 2 so that its tip is protruded on the ground. The wall of the tank proper 2 is comprised of a concrete layer 5 provided in a metal mold frame 4, a cold reserving layer 6 and a film layer 8 provided inside it in sequence, and a heater 7 inserted between the concrete layer and cold reserving layer. The inner periphery of the concrete layer 5 is heated by the heater 7 to reduce the temperature difference with the outer periphery and to reduce the thermal stress.
