Problems solved by technology
[0007] The purpose of the present invention is to provide a reinforced structure for a soil-covered double-shell low-temperature liquid hydrocarbon storage tank to solve the technical problems in the prior art that the outer tank of the soil-covered tank bears loads such as external uneven external pressure and the weight of the inner tank. Shaped insulation material can flow freely in the annular space, easy to fill, and can ensure low cooling loss

Embodiment Construction
[0029] The invention patent is further described below in conjunction with the accompanying drawings.
[0030] as attached figure 1 and attached figure 2 As shown, the reinforcing structure for a low-temperature liquid hydrocarbon storage tank of the present invention includes a top plate 11, a lattice member 12, a wing plate 13, a thermal insulation block 14 and the like.
[0031] see figure 2 and 3 , the layout of the reinforcement structure. The earth-covered double-shell low-temperature liquid hydrocarbon storage tank is composed of a double-shell horizontal storage tank 2, an overburden layer 3, a continuous sand bed foundation 4, and a civil foundation 5. The upper and surrounding areas of the double-shell horizontal storage tank 2 are covered with an overburden layer 3 , and a continuous sand bed foundation 4 is arranged in the bottom 120 corners, and the continuous sand bed foundation 4 is arranged on the civil foundation 5 .
[0032] The double-shell horizontal...

The invention discloses a reinforcing structure for an earthing double-shell low-temperature liquid hydrocarbon storage tank in the technical field of petrochemical engineering, and the earthing double-shell low-temperature liquid hydrocarbon storage tank consists of a double-shell horizontal storage tank, an earthing layer, a continuous sand bed foundation and a civil engineering foundation, and is characterized in that the reinforcing structure is uniformly distributed along the axial direction of the horizontal double-shell storage tank; the reinforcing structure comprises a top plate, lattice rod pieces and wing plates, the top plate, the lattice rod pieces and the wing plates are prefabricated into a circular ring structure through welding, and the lattice rod pieces are vertically, obliquely and crossly arranged along the circumference; two ends of the lattice rod piece are respectively welded with the wing plate and the top plate; the top plate is welded to the inner wall of the outer tank barrel, and heat insulation cushion blocks are arranged between the wing plates and the outer wall of the inner tank barrel. By the adoption of the reinforcing structure, the technical problem that the outer tank of the soil covering tank bears external uneven external pressure and loads such as the weight of the inner tank can be solved, meanwhile, it can be guaranteed that the granular heat insulation materials can freely flow in the annular space and are easy to fill, and it can be guaranteed that the loss of cooling capacity is small.
Description
technical field [0001] The invention belongs to the technical field of petrochemical industry, and particularly relates to a reinforcing structure for a low-temperature storage tank of liquid hydrocarbons. Background technique [0002] The earth-covered double-shell low-temperature liquid hydrocarbon storage tank is a large horizontal container without saddle support, which has the characteristics of low cost, small footprint and high safety. The above-mentioned double-shell storage tanks shall have the following functions: 1) To be filled with thermal insulation materials, and to maintain uniform circumferential thermal insulation, an annular space with a certain uniform gap must be ensured between the inner and outer tanks; 2) The weight of all metals and internal media in the inner tank must be The outer tank is supported; 3) The outer tank needs to withstand the effects of external covering, uneven settlement of the foundation, the reaction force of the foundation suppor...
