Abstract
The invention discloses a portable hydrogen storage alloy bottle which consists of a bottle body, a safe accessory and hydrogen storage alloy. Hydrogen storage alloy materials are filled in the bottle body; and the safe accessory is arranged at a mouth of the bottle body. The invention has the beneficial effects that the hydrogen storage alloy bottle designed by the technical scheme is convenient to carry and has a small volume; the stable gas is efficiently and continuously supplied for a long time; the hydrogen purity is high and reaches above 6N; and the portable hydrogen storage alloy bottle is suitable for being used as gas carrying, burning and tail blowing in a gas chromatograph and other instruments. The portable hydrogen storage alloy bottle has high safety. As metal hydrogen storage materials need to absorb heat in the hydrogen release, when being damaged under the action of outside force, the bottle body can but slowly release hydrogen stored inside the bottle body and even stop releasing the hydrogen due to surface icing.
Description
Technical field
The present invention relates to a kind of storage hydrogen bottle, be specially a kind of portable hydrogen bearing alloy bottle.Belong to storage hydrogen storage equipment field.
Background technique
Hydrogen Energy is enough burnt, and is a kind of fuel of higher calorific value, and the 1 kilogram of hydrogen that burns can be emitted the heat of 34000 kilocalories, does not also have any can comparing with it in the conventional fuel.In combustion process, hydrogen combines with oxygen to generate water, and water can not cause any pollution to environment.So hydrogen is one of the cleanest fuel.
Generally all use now a kind of steel high-pressure-resistant vessel---hydrogen cylinder is stored hydrogen.Even the hydrogen in the bottle is added to 150 barometric pressure, though this steel cylinder source of the gas pressure is very high, the continous-stable service life is long, volume and weight is all very big, and carrying is difficulty very.The weight of the hydrogen of adorning is also less than 1/100 of gas cylinder weight, and the danger of blast in addition.Obviously, this storage procedures in industry with a large amount of use hydrogen in life be inappropriate.For the ease of the usage requirement of moving, some manufacturer's designs have also been made several kinds of portable small steel cylinders, like portable oxygen small steel cylinder commonly used in the medical treatment, also have some chemical property such as argon gas or carbon dioxide than torpescence, the higher gas of Security.And active, the dangerous higher portable ultra-pure hydrogen storage hydrogen bottle of chemical property is also seldom seen.
Summary of the invention
The objective of the invention is for a kind of portable hydrogen bearing alloy bottle is provided, to solve the problem that existing technology is big to the dangerous height of storage of hydrogen, volume, be not easy to carry.
The object of the invention can be realized through following technological scheme.
A kind of portable hydrogen bearing alloy bottle is made up of bottle, safety attachment and hydrogen bearing alloy, fills alloy material storing hydrogen in the described bottle, is provided with safety attachment at the oral area of bottle.
Described alloy material storing hydrogen is the magnesium-nickel alloy material, and the magnesium of magnesium-nickel alloy material and the mol ratio of nickel are 3-5:1-2.Especially be 3:1.
Described magnesium-nickel alloy material, the purity of magnesium and nickel are 99.9% (mass fraction), and the granularity of magnesium powder is smaller or equal to 170 μ m, and the granularity of nickel powder is 20 μ m; Mixed-powder is placed the container that is loaded with acetone, mixed 30-60 minute, put abundant drying in the air, use press compacting mixed-powder to become the pressed compact of different size then with ultrasonic vibration.
Described safety attachment comprises the reset valve of using of closing or charging into minimum gas in the reduction valve of regulating the air pressure of giving vent to anger and the gas flow meter system, and described reduction valve is arranged on the sidewall of bottle opening subordinate side, and reset valve is arranged at the bottle top.
Described bottle diameter is 50mm, length 220mm.
Principle of the present invention is: alloy material storing hydrogen contacts with hydrogen; Hydrogen is decomposed into hydrogen ion and is adsorbed at alloy surface; Alloy is inner to generate metal hydride with alloy generation chemical reaction to hydrogen ion through diffusing into then, and hydrogen promptly is stored in the crystal lattice of metal surface with atomic state.Inhaling the H-H reaction formula is:
。
Through the hydrogen bearing alloy bottle that technological scheme of the present invention designs, easy to carry, volume is little; Efficiently, the sustainable supply stabilizing gas time is long, and hydrogen purity is high, and purity reaches more than the 6N, suits in instruments such as gas-chromatography, to do carrier gas, burning and tail and blows usefulness.Safety performance is high.Because metal hydrogen storage material will absorb heat when putting hydrogen, thus bottle meet external force and when damaging the hydrogen of its internal reservoir can only slowly discharge even stop to put hydrogen because of the surface freezes.
Description of drawings
Fig. 1 is the structural representation of air cylinder of the present invention;
Among the figure: 1, bottle 2, alloy material storing hydrogen 3, safety attachment.
Embodiment
Further set forth technical characterstic of the present invention below in conjunction with accompanying drawing and specific embodiment.
A kind of portable hydrogen bearing alloy bottle as shown in Figure 1 is made up of bottle 1, safety attachment 3 and alloy material storing hydrogen 2, fills alloy material storing hydrogen 2 in the described bottle 1, is provided with safety attachment 3 at the oral area of bottle 1.
Described alloy material storing hydrogen 2 is the magnesium-nickel alloy material, and the magnesium of magnesium-nickel alloy material and the mol ratio of nickel are 3-5:1-2.Especially be 3:1.
Described magnesium-nickel alloy material, the purity of magnesium and nickel are 99.9% (mass fraction), and the granularity of magnesium powder is smaller or equal to 170 μ m, and the granularity of nickel powder is 20 μ m; Mixed-powder is placed the container that is loaded with acetone, mixed 30-60 minute, put abundant drying in the air, use press compacting mixed-powder to become the pressed compact of different size then with ultrasonic vibration.
Described safety attachment 3 comprises the reset valve of using of closing or charging into minimum gas in the reduction valve of regulating the air pressure of giving vent to anger and the gas flow meter system, and described reduction valve is arranged on the sidewall below bottle 1 oral area, and reset valve is arranged at bottle 1 top.
The key technical indexes is following:
Stored-gas: high-purity hydrogen, purity reaches 99.9999%.
The steel cylinder capacity: the amounts of hydrogen of storage big (greater than 200 liters), the amounts of hydrogen that metal hydrogen storage material stores can reach 1000 times of own volume, is common High Pressure Hydrogen gas cylinder (150kg/cm
2) 6 ~ 7 times, so that it takes up space is little.
Pressure :≤10 kilograms
