Description
Technical field
The present invention relates to a kind of concrete caisson of the LNG of carrying storage tank, belong to liquefied natural gas storing technology field.
Background technology
At present, for carrying LNG(liquefied natural gas) technology of storage tank is mainly following two kinds:
(1) land concrete holds tank entirely, and interior tank material is 9%Ni steel, and outer tank is prestressed concrete, and tank deck is steel concrete.Annular space at the bottom of tank, between interior outer tank and inner canister furred ceiling all adopt thermal insulation material (foam glass, expanded perlite and glass wool) to carry out cold insulation.Build traditional land storage tank, must build in the site that has water front, if there is no tank field land-based area, also need marine reclamation land, not only invest huge, and long in time limit.A large amount of marine reclamation lands, also can damage marine ecology.Document (Wang Bing, Chen XueDong, kingdom's equality. the new development of large-scale low-temperature LNG tank designs and building technology [J]. gas industry, 2010,30 (5): 108-112.DOI:10.3787/j.issn.1000-0976.2010.05.028. and Yin Jingsong, Ma little Hong, old tertiary equality.
