Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1 to Figure 5 As shown, the 400,000 cubic meters double-wall fixed hydraulic balance floating roof oil tank in this embodiment is used to illustrate the structure of the storage tank.

[0021] First of all, it is necessary to calculate the materials used for the inner tank, outer tank and T-shaped steel according to the design volume of the storage tank.

[0022] The difference from the calculation method of ordinary oil tanks is that the influence of the balance side pressure should be considered when calculating the strength of the tank wall of the fixed hydraulic balance oil tank. The calculation of the strength of the inner tank wall should be divided into two parts. The part above the hydraulic balance point is the same as that of the ordinary tank wall. The part below the hydraulic balance point should consider th...

Abstract

The invention relates to a wall board structure of a fixed hydraulic balance extra large storage tank. The structure comprises an inner tank and an outer tank, wherein the inner tank is used for storing materials; the outer tank is wrapped by the inner tank; a distance is arranged between the outer side wall of the inner tank and the inner side wall of the outer tank so as to form an annular space for containing liquid for balancing pressure; and the structure is characterized in that a plurality of structural steel connecting pieces for improving the bearing capability of the side wall of the inner tank are arranged between the inner side wall of the outer tank and the outer side wall of the inner tank. Compared with the prior art, the invention really realizes the manufacturing of an extra storage tank, has the advantages of low the manufacturing cost, and ensures the welding quality.

Description

technical field [0001] The invention relates to a large storage tank, in particular to a fixed hydraulic balance super large storage tank wall plate structure. Background technique [0002] With the continuous expansion of the production scale of petrochemical enterprises and the increase of strategic petroleum reserves, the scale of petroleum reserves has developed rapidly. For a long time, various countries have been building a large number of large reserve oil depots, taking increasing oil stocks as an important measure to stabilize production and ensure national security. In order to meet the needs of mass storage, the use of large storage tanks has become an inevitable trend. Because large-capacity storage tanks can save steel, reduce floor space, facilitate operation and management, reduce storage tank accessories and pipeline length, thereby saving investment and operating costs. As early as the 1960s, 10×10 was widely used in Western Europe, the Middle East, Japan ...
