Description
Technical Field
The utility model belongs to the technical field of hydrogen safety utilizes, concretely relates to explosion-proof double-deck high pressure hydrogen storage tank.
Background
With the over-exploitation and utilization of traditional fossil energy (petroleum and coal), reserves thereof are increasingly exhausted, and a series of serious environmental, ecological and social problems are caused. And the development and utilization of new alternative energy sources are important measures for solving the problems. Hydrogen is praised as an energy source in the future due to its characteristics of cleanliness (the reaction product is only water) and high efficiency. However, the safety of hydrogen utilization has been one of the major bottlenecks that restrict the development of hydrogen energy industry.
Hydrogen storage safety is a central issue throughout the various stages of hydrogen utilization, including production, storage, transportation and use. Domestic and foreign research shows that high-pressure hydrogen storage is the optimal choice from the viewpoint of economic benefit and energy utilization. However, since hydrogen has dangerous characteristics such as wide combustion limit, low ignition energy, fast flame propagation speed, hydrogen embrittlement, etc., once accidental leakage of high-pressure hydrogen occurs, fire and explosion accidents may be caused. In particular, a high pressure hydrogen leak can self-ignite and form a strong jet flame, even causing an explosion of the gas cloud, without the action of any external ignition source.
The existing storage tank structure is also mainly divided into a single-layer structure and a double-layer structure. Wherein, the single-layer structure is more widely used because of simple manufacture and low price. The double-layer structure storage tank mainly utilizes an interlayer (vacuumized or filled with materials) to realize the functions of heat preservation and heat insulation. Therefore, the urgent need of safely storing high-pressure hydrogen cannot be met no matter the structure is a single-layer or double-layer storage tank, and particularly, the accident of accidental leakage and explosion of the high-pressure hydrogen which may happen cannot be effectively controlled.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems of the prior art, the utility model provides a double-layer high-pressure hydrogen storage tank which can effectively prevent the high-pressure hydrogen from leaking spontaneous combustion and inhibiting the gas cloud explosion.
The technical scheme of the utility model as follows:
the utility model provides an explosion-proof double-deck high pressure hydrogen storage tank, the storage tank including the jar body with set up in the tank seat of the jar body, the jar body have be used for holding high pressure hydrogen the inner tank and with the inner tank form interbedded outer jar, the intermediate layer intussuseption be filled with explosion suppression agent, explosion suppression agent can be for water, carbon dioxide, nitrogen gas or other explosion suppression agent, preferred liquid water, compressed nitrogen gas, liquid nitrogen gas, compressed carbon dioxide, liquid carbon dioxide, or other explosion suppression agent, outer jar be provided with explosion suppression agent import and explosion suppression agent export, the inner tank set up and be connected with outer jar and lead to the hydrogen exit outside the jar.
Preferably, the inner tank and the outer tank are connected through the tank seat.
Preferably, the tank body is a steel tank body, a glass fiber reinforced plastic tank body, a carbon fiber tank body or a high polymer material tank body.
Preferably, the tank body is a vertical cylindrical tank body, a horizontal cylindrical tank body or a spherical tank body.
Preferably, the hydrogen inlet and outlet are isolated from the interlayer.
The technical effects of the utility model are as follows:
the utility model discloses a storage tank specially adapted high pressure hydrogen takes explosion suppression agents such as carbon dioxide, nitrogen gas to fill the storage tank intermediate layer for the first time. On the one hand, the hydrogen gas is strongly diffusible and may cause hydrogen embrittlement damage to the tank material, and on the other hand, the hydrogen gas tank may be damaged by accidental bumping, dropping or squeezing, which may cause leakage of the stored high-pressure hydrogen gas. When the inner tank is leaked, the hydrogen can be mixed with the filling materials (liquid water, compressed or liquid nitrogen, carbon dioxide or other explosion suppressants) in the interlayer to form an inerted gas mixture, so that the explosion risk is obviously reduced. If the outer tank is subsequently also ruptured and leaks, the high-pressure gas mixture will not spontaneously ignite by leakage, significantly reducing the immediate hazard of a leakage event.
When the inner tank and the outer tank are damaged simultaneously and cause high-pressure hydrogen to leak, the filling materials (liquid water, compressed or liquid nitrogen, carbon dioxide or other explosion suppressants) in the interlayer can leak together with the hydrogen, and the high-pressure hydrogen is prevented from leaking and spontaneously combusting through the double effects of physical inhibition and chemical kinetic inhibition.
The hydrogen leaked to the outside of the storage tank can obviously reduce the occurrence probability and destructive power of gas cloud explosion due to the physical and chemical explosion suppression effects of the media because of the mixed water, carbon dioxide, nitrogen or other explosion suppressants.
In the storage tank filled with the explosion suppressant in the interlayer provided by the utility model, the explosion suppressant such as water, carbon dioxide and nitrogen can greatly reduce the occurrence probability by improving the initial pressure condition required by spontaneous combustion due to leakage; on the other hand, the overpressure generated by the gas cloud explosion can be obviously reduced, so that the destructive power of the explosion can be effectively weakened.
Therefore, the storage tank provided by the utility model can effectively prevent the spontaneous combustion caused by the accidental leakage of the high-pressure hydrogen and inhibit the explosion of gas cloud; and the structure is simple, and the economic advantage is obvious.
