ADIABATIC MATERIAL SUPPORTING STURUCTURE OF SIDE BULKHEAD IN DUALLSHELL RESERVOIR

摘要

PURPOSE:To prevent precipitation of adiabatic material at the time of using for low temperature in such a way that an intermediate mural body unit in possession of arcuate faces which are flexible and opposite to the external shell is strongly jointed at vertical sides, and grained adiabatic material is filled in the space formed by supporting its jointed parts. CONSTITUTION:Intermediate mural body 40 is provided between the internal shell 2 and the external shell 3. This intermediate mural body 40 is formed by strongly jointing vertical sides 42 contiguous to intermediate mural body units 41 with the size split the circumference, whose jointed parts are supported to the external shell 3. And grained adiabatic material 5 is filled between the external shell 3 and the intermediate mural body 40. Thus, when there is any change in the temperature, vertical sides 42 taken as fulcrums, arcuate parts 44 in the intermediate mural unit 41 are deformed, the entirety of the intermediate mural body 40 is compensated in its dilatation and contraction. Besides, precipitation is prevented at the time of using for low temperature in such a way that gaseous matter penetrative material, such as cloth, etc. is used for the intermediate mural body units 41, gaseous matter contained in the grained adiabatic material is made to be escapable into the space between it and the internal shell 2, and the grained adiabatic material is precipitated at an early stage.
