专利汇可以提供Method of preventing secondary protective wall of low temperature lng tank from extraordinary temperature drop专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent the secondary protective wall of an independent low temperature LPG/LNG tank of an LPG/LNG ship from localized extraordinary temperature drop by vaporizing LPG/LNG leaked out onto the outer surface of the tank through its contact with liquid.
CONSTITUTION: If low temperature LPG/LNG leaks from an independent low temperature LNG tank 1 of an LPG/LNG ships liquid such as water or seawater is sprayed through a sprayer pipe 3, thereby leaked LPG/LNG is contacted with the liquid and vaporized. Thus, the constitution enables to prevent a secondary protective wall 2 of the tank 1 from being cooled locally by LPG/LNG leaked out from the tank and improving the low temperature resistance of the material, by which the secondary protective wall is constituted, compared with that of the independent tank.
