Metal hydride reactor portion loads and stores up the hydrogen alloy, and import and export be all through the valve control, the hydrogen source of the lower purity of inlet connection, the hydrogen of higher purity after the exit end is emitted and is purified to arrive the hydrogen equipment of using through flow and pressure control headtotail. Utilize this hydrogen purifier, can realize purifying in succession hydrogen, the higher purity hydrogen of incessant output to control output flow rate and pressure, convenient operation, the operation is stable.
Description
Technical field
The present invention relates to a kind of hydrogen purification device, based on solid-state hydrogen storage technology, achieve the purifying to hydrogen, belong to the accumulating of hydrogen, purification and supply field.
Background technology
The aggravation of and problem of environmental pollution increasingly exhausted along with petroleum-based energy, people start sight to forward in alternative, the renewable energy resources.Hydrogen Energy be world all at the clean energy of active research and exploitation, there is the advantages such as combustion heat value is high, no pollution, aboundresources, be widely used at present in all trades and professions.
Along with the requirement of every profession and trade to hydrogen is more and more higher, how to improve the problem that hydrogen purity has become market in urgent need solution further.The method of the ultra-pure hydrogen of preparation conventional at present has: palladium-silverskin thermal diffusion method, low-temperature adsorption, pressure swing adsorption process.
Low-temperature adsorption is hydrogen_cooling to liquid nitrogen temperature (-196 DEG C), and use Special adsorbent removes the institute's residual impurities in hydrogen, makes it reach purifying object, makes the hydrogen produced in this way reach more than 5N.Because this method is carried out under the condition of very low temperature, so have higher requirement to production unit, the bad meeting of equipment causes energy dissipation, and product cost improves, and e-quipment and pipe frosting flowing water etc., also make production environment degenerate.
Pressure-variable adsorption (PSA) method utilizes sorbent material to the adsorptive power of impurity composition in feed hydrogen, reaches the object of purifying hydrogen of hydrogen, has the advantage that disposable separation removes plurality of impurities component simultaneously.But the rate of recovery of the hydrogen that the method obtains is relevant with many factors, and declines with the raising of product hydrogen purity, and such as, when product hydrogen purity is 99.9 ~ 99.99%, the hydrogen recovery rate of three towers or four-column process flow is 70 ~ 75%.
Wherein, the obtained hydrogen purity of palladium-silverskin thermal diffusion method is the highest, but expensive, and the damage easy to crack of palladium-silverskin, maintenance and working cost high.All in all, ultra-pure hydrogen production difficulty is large, turnout is little.
The selectivity of hydrogen storage alloy suction hydrogen and reversible hydrogen adsorption and desorption characteristic purifying hydrogen of hydrogen is utilized to be a kind of important method, metal hydride inside reactor fills hydrogen storage alloy, hydrogen storage alloy only and hydrogen generation chemical reaction generation metal hydride, and the foreign gas in hydrogen accumulates in the space of inside reactor because reacting, the foreign gas these gathered is discharged, then decomposition of metal hydrides releases pure hydrogen, so just achieves the purification to hydrogen.The method for hydrogen purity high, cost is low, easy to operate, stable, can Industry Promotion application, there is good development prospect and the wide market space.
Summary of the invention
For the demand of every profession and trade to high-purity hydrogen, the invention provides a kind of hydrogen purification device, the selectivity of hydrogen storage alloy is utilized to inhale hydrogen and reversible hydrogen adsorption and desorption characteristic, under certain condition hydrogen storage alloy with generate metal hydride compared with the H-H reaction in low-purity hydrogen, and the foreign gas in hydrogen accumulates in the space of inside reactor because reacting, the foreign gas these gathered is discharged, and then decomposition of metal hydrides releases pure hydrogen, so just achieves the purification to hydrogen.This device utilizes the alternate run of more than two or two metal hydride reactors, realizes the continuous purification to hydrogen and uninterrupted hydrogen supply.
The technical solution adopted in the present invention is: provide a kind of hydrogen purification device, this device comprises at least two metal hydride reactors and a control of flow and pressure system, metal hydride inside reactor filling hydrogen storage alloy, import and outlet all pass through Valve controlling, entrance end connects hydrogen source, and exit end is by control of flow and pressure system connection hydrogen storage equipment.
Two or more metal hydride cleaner hocket inhale hydrogen, put hydrogen, realize continuous purification hydrogen, uninterruptedly export high-purity hydrogen.
Metal hydride inside reactor fills Rare Earth, titanium system or magnesium microalloying.
Metal hydride reactor outlet end valve door is three-way valve, and after metal hydride reactor completes and inhales hydrogen, first by three-way valve, foreign gas is emptying, then decomposition of metal hydrides releases pure hydrogen, can realize the object of purifying hydrogen of hydrogen.
The flow that control of flow and pressure Systematical control hydrogen exports and pressure, the requirement of satisfied hydrogen storage equipment.
Utilize this hydrogen purification device, can by compared with the continuous purifying of the hydrogen of low-purity, supply hydrogen storage equipment uses, and by control of flow and pressure system, controls output flow and pressure, easy to operate, stable.
