Embodiment Construction

[0029] In order to describe the technical content of the present invention more clearly, further description will be made below in conjunction with specific embodiments.

[0030] Figure 1 ~ Figure 3 They are schematic diagrams of horizontal cylindrical storage tank, vertical cylindrical storage tank and spherical storage tank respectively. Wherein, the tank body is a double-layer structure, consisting of an inner tank 2 and an outer tank 1, the inner tank 2 and the outer tank 1 are connected as a whole through the tank seat 7; a sandwich 3 is formed between the inner tank 2 and the outer tank 1, and the inner tank 3 Filled with antiknock agent, said antiknock agent can be liquid water, compressed nitrogen, liquid nitrogen, compressed carbon dioxide, liquid carbon dioxide, or other antiknock agents, and the outer tank 1 is provided with an antiknock agent inlet 5 and an antiknock agent outlet 6. It is used to fill or release the anti-knock agent filling into the interlayer 3;...

Abstract

The invention relates to an explosion-proof double-layer high-pressure hydrogen storage tank. A tank body of the tank comprises an inner tank and an outer tank which are integrally connected by tank holders; an interlayer between the inner tank and the outer tank is filled with an explosion inhibitor, and the interlayer is provided with an explosion inhibitor inlet and an explosion inhibitor outlet; the inner tank is connected with the outer tank by a pipeline which leads to the outside of the tank, and the pipeline is separated from the interlayer. The storage tank is mainly used for storinghigh-pressure hydrogen. The storage tank can effectively prevent spontaneous combustion of high-pressure hydrogen due to accidental leakage and inhibit gas cloud explosion, and has simple structure and obvious economic advantage.

Description

technical field [0001] The invention belongs to the technical field of safe utilization of hydrogen, and in particular relates to an explosion-proof double-layer high-pressure hydrogen storage tank. Background technique [0002] With the excessive development and utilization of traditional fossil energy (oil and coal), its reserves are increasingly depleted, and a series of serious environmental, ecological and social problems have been caused. The development and utilization of new alternative energy is an important measure to solve these problems. Hydrogen, because of its cleanness (the reaction product is only water) and high efficiency, is known as the future energy star. However, the safety of hydrogen utilization has always been one of the main bottlenecks restricting the development of the hydrogen energy industry. [0003] The safety of hydrogen storage is the core issue throughout all aspects of hydrogen utilization (including production, storage, transportation a...
