Single-shell multi-layer mixed spherical storage tank and manufacturing technology thereof

Abstract

The invention discloses a single-shell multi-layer mixed spherical storage tank and a manufacturing technology thereof. The single-shell multi-layer mixed spherical storage tank comprises a mixed shell in which a manhole and a feeding and discharging port are reserved. The mixed shell comprises an equatorial zone, temperate zones and polar plates. A tangerine section manner is adopted in the equatorial zone and the temperate zones, and a football section manner is adopted in the polar plates. A lining layer is arranged on the inner wall of the mixed shell. The outer wall of the mixed shell is sequentially provided with a compression resisting layer, a pulling resisting layer, a rustproof layer and an abrasion resisting layer from interior to exterior. The storage tank is more stable in structure, and the service life of the spherical storage tank is effectively prolonged. The machining process is simple, implementation is easy, the material utilization rate during storage tank manufacturing is effectively increased, and the problems of manpower waste and material resource waste due to complex procedures are solved. Meanwhile, the stability of a tank body is improved, the sealing performance of the storage tank is guaranteed, gas or liquid leakage difficultly happens to the storage tank, and the service life of the spherical storage tank is prolonged to a certain degree; and possibility of explosions, fire disasters and other accidents caused by leakage is reduced.

Description

Technical field [0001] The invention relates to the process route field of spherical storage tank technology, in particular to a single-shell multi-layer hybrid spherical storage tank and a manufacturing process thereof. Background technique [0002] Spherical storage tank is a pressure vessel used to store liquid, gas or liquefied gas. Because of its thin wall thickness, light weight, less materials, low cost, and less floor space, it is widely used in petroleum, petrochemical, chemical, metallurgical and other industrial fields and some other industries. According to the form of the spherical shell, it can be divided into a football petal type, an orange petal type, and a hybrid type combining the two. The football petal type welds are complicated in layout, construction and assembly are difficult, and the orange petal type is complicated in blanking and forming, and the utilization rate of the plate is low. Use a hybrid combination of the two. The hybrid type combines the st...

AI Technical Summary

Problems solved by technology

However, the structure of the single-layer spherical tank is relatively simple, and the wall thickness is thin.

Most of the spherical tanks store flammable, explosive or toxic media. Once an accident occurs, it will not only cause the leakage and release of the media, but also cause a series of serious accidents such as poisoning, pollution, etc.
