Land thin film liquid hydrogen storage tank with high-vacuum insulation box

Abstract

The invention discloses a land thin film liquid hydrogen storage tank with a high-vacuum insulation box, which belongs to the technical field of storage tank devices and comprises a concrete outer tank, a moisture-proof layer, the high-vacuum insulation box, an inner side secondary insulation layer, a secondary shielding layer, an inner side main insulation layer, a main shielding layer, a steel tank top, a concrete tank top and a concrete bottom plate. An independent film shielding layer liquid containing system is achieved, the heat insulation mode of the high-vacuum insulation box is adopted, the insulation and cold insulation performance of a traditional film type storage tank is improved, the evaporation rate is further reduced, and the storage time of liquid cargo hydrogen in the storage tank is prolonged; the liquid hydrogen thin film type storage tank is used for storage and transportation of a land vertical liquid hydrogen storage tank, a liquid hydrogen ship fuel cabin and a liquid hydrogen transport ship liquid cargo cabin, the limitation of a hydrogen storage pressure container is broken through, the hydrogen storage requirement is met by adopting a normal-low pressure container, and the liquid hydrogen thin film type storage tank is brand new, wider in application, safer and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of refrigerated liquefied gas-liquid hydrogen (LH2) low-temperature storage devices, in particular to a thin-film liquid hydrogen storage tank for land use with a high-vacuum insulation box. Background technique [0002] As an emerging energy, hydrogen has the advantages of high efficiency, cleanness, pollution-free and sustainable. With the rapid development of my country's economy and the continuous improvement of environmental governance requirements, hydrogen is currently one of the most promising clean energy. [0003] Although the hydrogen-dominated economic system has been established for a long time, due to various reasons such as lack of technology, infrastructure or investment, the industry has been hovering in the energy transition, however, in recent years, with the global Driven by decarbonization, and the development of existing technologies, the hydrogen economy is expected to accelerate on a ...
