Wall board structure of fixed hydraulic balance extra large storage tank

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 ...

AI Technical Summary

Problems solved by technology

However, this kind of hydraulic balance storage tank must ensure the quality of the butt joint welding of the inner and outer wall panels, so the size of the annular space must ensure that construction personnel can enter the construction, and the distance between the inner and outer wall panels is relatively large

At the same time, the liquid level in the annular space must be adjusted and controlled according to the liquid level of the inner tank at any time. Once the inner tank is out of control, the inner tank may be damaged; this requires the installation of liquid filling pipes and related control systems in the annular space; if The annular space is filled with the same liquid as the inner tank, and there are still problems with the sealing and safety of the upper part of the annular space; if the annular space is filled with a safe liquid medium, a storage tank should be made for it

Not only the structure is complicated, but also its construction cost and floor space are not advantageous compared with the current single-wall large storage tanks

[0004] Therefore, no one has produced a hydraulically balanced super-large storage tank so far.
