Metal full-volume storage tank with secondary container protecting layer

Abstract

The invention provides a metal full-volume storage tank with a secondary container protecting layer. The metal full-volume storage tank comprises a primary container, a secondary container which is located at the periphery of the primary container and contains the primary container therein and the secondary container protecting layer which is arranged between the primary container and the secondary container in a separating manner; a bottom plate of the primary container and a bottom plate of the secondary container protecting layer are spaced through a concrete leveling layer; a bottom insulating layer formed by laminating a plurality of insulating structures is arranged between the bottom plate of the secondary container protecting layer and a bottom plate of the secondary container; cold insulating materials fill an interlayer between the side wall of the secondary container protecting layer and the side wall of the primary container, an interlayer between the side wall of the secondary container protecting layer and the side wall of the secondary container and an interlayer between the side wall of the primary container above the secondary container protecting layer and the side wall of the secondary container to form interlayer heat insulating layers; the interlayer heat insulating layers fixedly support the side wall of the secondary container protecting layer between the primary container and the secondary container. According to the metal full-volume storage tank provided by the invention, the heat insulating property of the bottom insulating layer is fully exerted and the integral construction period of the storage tank is shortened.

Description

technical field [0001] The invention relates to the field of low-temperature and cryogenic medium storage equipment, in particular to a metal full-capacity storage tank with a protective layer of a secondary container. Background technique [0002] In recent years, with the continuous development of my country's economy, social conflicts caused by land have become increasingly fierce, and land prices have been rising day by day. As a large-scale terminal storage equipment, the single-contained atmospheric storage tank used to store low-temperature media requires the construction of the equipment itself. Occupying a large amount of land, and considering the safety of single-contained storage tanks, cryogenic medium storage factories need to reserve a large amount of land space for them as safety cofferdams to prevent potential safety hazards caused by leakage of stored low-temperature medium. At the same time, low temperature and atmospheric pressure storage tanks store a larg...
