Background technique
In recent years, be protected for the mankind rely the earth environment according to existence, reduce the pollution of carbon dioxide to atmosphere, diversiform electric vehicle development develops rapidly, and the fuel cell electric vehicle development of one of them is very fast.Fuel cell carries out electrochemical reaction by hydrogen and airborne oxygen and produces electric energy.Fuel cell comprises following important several parts: compressed-air actuated air feeder can constantly be provided; Can discharge the air releasing device of unnecessary air; The hydrogen gas supplying apparatus of hydrogen can constantly be provided; Can discharge unnecessary hydrogen and unnecessary hydrogen is sent back to hydrogen gas supplying apparatus and carry out recycling hydrogen releasing device; Can make the temperature maintenance cooling unit within the specific limits of fuel cell.The normal operation of these important device just can make fuel cell constantly produce.
The hydrogen gas supplying apparatus of fuel cell system typically has: from the reforming reactor of reformation hydrogen productions such as hydrogeneous liquefied petroleum such as methyl alcohol; Storage has the High Pressure Hydrogen storage facility of high pressure hydrogen; Compare the metal Hydride Hydrogen Storage Tanks that under low pressure to store hydrogen with the High Pressure Hydrogen storage facility.Metal Hydride Hydrogen Storage Tanks is made up of aluminium or stainless steel casing and interior metal hydride hydrogen storing alloy, and metal Hydride Hydrogen Storage Tanks storage hydrogen density is higher than the storage hydrogen density of High Pressure Hydrogen storage facility.The metal hydride hydrogen storing alloy will produce volumetric expansion and compression in the process of storage and release hydrogen, inhale repeatedly to put the metal hydride particle generation efflorescence of hydrogen circulation back.
In making the process of metal Hydride Hydrogen Storage Tanks, earlier with the hydrogen storing alloy mechanical crushing of bulk to the particle that requires size, in the hydrogen-storage tank of subsequently the granular hydrogen storing alloy being packed into.How many granular hydrogen storing alloys of packing into are suitable, must consider the factors such as volumetric expansion after apparent density, tap density and the Hydrogen Storage Alloys.Will the hydrogen storing alloy in the hydrogen-storage tank be activated then, normally hydrogen-storage tank directly is associated on the activating apparatus and carries out.The granular hydrogen storing alloy of packing in hydrogen-storage tank is too many, and volumetric expansion is burst the hydrogen-storage tank shell easily in activation process because after the Hydrogen Storage Alloys; The granular hydrogen storing alloy of packing in hydrogen-storage tank will be opened hydrogen-storage tank and add hydrogen storing alloy very little after the activation, hydrogen storing alloy is subject to airborne dioxygen oxidation like this, need reactivate.
Summary of the invention
The purpose of this utility model provides a kind of non-oxidation, easy-operating hydrogen-storage tank activation making device.
The purpose of this utility model is achieved through the following technical solutions.
A kind of hydrogen-storage tank activation making device, it is made up of activated bottle 1, connecting flange 2, intervening valve 3, connecting flange 4 and hydrogen storage bottle 5, it is characterized in that activated bottle 1 top left is provided with vacuum pumping valve 6 and pressure meter valve 7, top right is provided with hydrogen charging valve 8 and hydrogen discharging valve 9; Open Side Down for activated bottle 1, and hydrogen storage bottle 5 openings make progress, and activated bottle 1 is by connecting flange 2, intervening valve 3 and connecting flange 4 and hydrogen storage bottle 5 close-coupled.
Be applicable to that hydrogen storing alloy of the present utility model can be MmNi
5Base, basic, the TiMn of TiFe
1.5Base and TiV base hydrogen-storing alloy; The state of hydrogen storing alloy can be as cast condition, rapid solidification state and annealing in process state.The hydrogen storing alloy mechanical crushing of bulk to several millimeter-sized particles, is packed into the granular hydrogen storing alloy in the activated bottle subsequently, activated bottle is vacuumized by vacuum pumping valve.Fill hydrogen to 4Mpa by hydrogen charging valve then, hydrogen storing alloy is inhaled hydrogen and is produced volumetric expansion under the hydrogen effect, puts in the hydrogen process in suction subsequently and can constantly ftracture and efflorescence owing to the volumetric expansion hydrogen storing alloy.
Activated bottle links by two connecting flanges and intervening valve and hydrogen storage bottle, and this connection is tight air proof.Intervening valve can be a ball valve, is the state of vacuumizing in the hydrogen storage bottle.Just can not be subjected to air oxidation when the Powdered hydrogen storing alloy that activation is good in the activated bottle is packed hydrogen storage bottle into by intervening valve like this.
Hydrogen-storage tank activation making device of the present utility model can not only effectively stop the oxidation of hydrogen storing alloy air in activation and bottling process, and simple to operate, with low cost.Be very suitable for making hydrogen reservoir, hydrogen gas cleaner and fuel cell hydrogen source hydrogen-storage tank.

Embodiment
Be described in detail below in conjunction with 1 pair of the utility model of accompanying drawing.
Main structure of the present utility model is the hydrogen-storage tank activation making device that activated bottle 1, connecting flange 2, intervening valve 3, connecting flange 4 and hydrogen storage bottle 5 (see figure 1)s are formed, and activated bottle 1 top is provided with vacuum pumping valve 6, pressure meter valve 7, hydrogen charging valve 8 and hydrogen discharging valve 9.With the hydrogen storing alloy mechanical crushing of bulk to several millimeter-sized particles.Be applicable to that hydrogen storing alloy of the present utility model can be MmNi
5Base, basic, the TiMn of TiFe
1.5Base and TiV base hydrogen-storing alloy; The state of hydrogen storing alloy can be as cast condition, rapid solidification state and annealing in process state.The granular hydrogen storing alloy is packed in the activated bottle 1, open vacuum pumping valve 6 activated bottle 1 is evacuated to 1 * 10
-3～1 * 10
3The Mpa scope is closed vacuum pumping valve 6 subsequently.Open hydrogen charging valve 8 then and at room temperature fill hydrogen to 4Mpa, also can fill hydrogen under 10～80 ℃, it is low more to fill the hydrogen temperature, and the Hydrogen Storage Alloys amount is many more; Filling hydrogen pressure can carry out in 2～6Mpa scope, and it is high more to fill hydrogen pressure, and the Hydrogen Storage Alloys amount is many more.Hydrogen Vapor Pressure in activated bottle 1 reaches preset pressure, and opens pressure meter valve 7 and close hydrogen charging valve 8, thinks when Hydrogen Vapor Pressure does not descend substantially in the pressure gauge demonstration activated bottle 1 and fills the hydrogen abundance.Open hydrogen discharging valve 9 when putting hydrogen and hydrogen introduced outdoor, put hydrogen and finish and close hydrogen discharging valve 9, inhale hydrogen once and the hydrogen of putting subsequently once put the hydrogen circulation primary for inhaling.Hydrogen storing alloy activates under the hydrogen effect in activated bottle 1 to be inhaled hydrogen and produces volumetric expansion, puts in the hydrogen process in suction subsequently and can constantly ftracture and efflorescence owing to the volumetric expansion hydrogen storing alloy.The particle of hydrogen storing alloy can reach-300 orders, and the particle size that increases hydrogen storing alloy of putting the hydrogen cycle-index with suction can be littler.The whole activation process of hydrogen storing alloy all is enclosed in the activated bottle 1 carries out, and airborne oxygen is can not enter in the activated bottle, so just can effectively stop the oxidation of hydrogen storing alloy in activation process.
