Description

Medium-sized volume vertical deep-cold pressure container supporting structure

Technical Field

The utility model relates to the technical field of deep-cold pressure container support, in particular to a medium-volume vertical deep-cold pressure container support structure.

Background

The deep-cold pressure container is mainly used for storing frozen liquefied gas (the critical temperature is below minus 50 ℃), and the structure of the deep-cold pressure container comprises an outer tank, an inner container, a pipeline system and the like; the outer tank is connected with the inner tank through a supporting structure to form a stable and reliable integral structure. Because the temperature of the stored cryogenic medium is very low, heat can be continuously absorbed from the external environment in the use process, so that the saturation of the cryogenic medium in the tank is increased; the increased saturation is detrimental to long-term storage of the medium (e.g., relief valve trip emissions).

Therefore, in the design of the deep-cold pressure container, the design of the supporting structure between the outer tank and the inner container is particularly important, and the supporting structure has important influence on the cold insulation performance of the deep-cold pressure container. The most commonly used supporting structure of the medium-sized volume vertical type deep-cold pressure container in the industry at present is a side wall type steel pipe support, and the structure has the defect of larger heat leakage due to the fact that metal is adopted as a supporting material.
