High vacuum multilayer heat-insulation copious cooling double-shell spherical storage tank

The utility model relates to a high vacuum multilayer heat-insulation copious cooling double-shell spherical storage tank, which comprises an outer spherical tank and an inner spherical tank arranged in the outer spherical tank. The inner spherical tank is supported in the outer spherical tank through an upper fixing and supporting member at the upper portion of the inner spherical tank and a lower fixing and supporting member at the lower portion of the inner spherical tank. A laminated inner supporting member is arranged between the inner spherical tank and the outer spherical tank, heat insulation materials are wrapped on the outer surface of the inner spherical tank, and a strengthening plate is arranged on the outer surface of the outer spherical tank. An upper support is welded on the strengthening plate through an equator tangent structure and fixedly connected with a lower support through heat insulation materials, and a drawing rod is arranged between the upper support and the lower support. The high
