The utility model discloses a hydrogen supercharging device adopts electric heating methods, and the pressure boost is fast, efficient, and system's noiseless, easy operation, maintenance are convenient, have fine market perspective.
Description
Technical field
The present invention relates to a kind of method of hydrogen pressurization, utilize metal hydride to put hydrogen platform pressure at a lower temperature lower, put the principle that hydrogen platform pressure is higher at relatively high temperatures, reach the object of hydrogen pressurization.
Background technique
According to thermodynamic property, metal hydride is put hydrogen pressure variation with temperature and is followed Van ' tHoff equation: lnP
d=△ H
0/ RT-△ S
0/ R, wherein, Pd for putting hydrogen balance pressure, △ H
0with △ S
0for enthalpy change and the Entropy Changes of reaction.
When hydrogen bearing alloy inhale under lower temperature and lower pressure hydrogen saturated after, metal hydride temperature is elevated to higher temperature, and now metal hydride will release the hydrogen of high pressure.Metal hydride hydrogen compressor had both utilized this characteristic work of hydrogen bearing alloy, different according to the hydrogen storage material selected, and can realize the pressurized effect of different proportion.
Hydrogen compressor ripe is in the market mechanical compressor, this compressor because of by compression than restriction, generally multi-stage booster is all needed to reach high-pressure, there is the shortcomings such as volume is large, Heavy Weight, power consumption are high, and can reduction hydrogen purity to a certain degree, also need to set up hydrogen purification equipment.
Metal hydride hydrogen compressor compact structure, pressurized effect is obvious, has great application prospect.But metal hydride hydrogen compressor in the market, operation is comparatively complicated, because adopting water-bath, oil bath heating more, the sealing, stability etc. of equipment itself are had a significant impact, and this mode high/low temperature heat exchange interval is large, cause compression interval longer, compression efficiency is low, be difficult to realize large-scale promotion application.Comparatively speaking, Electric heating quick heating, stable temperature control, can be designed to various shape and adapt to equipment to be heated, but high temperature is comparatively slow to low temperature conversion, does not therefore substantially apply on metal hydride hydrogen compressor.
Summary of the invention
For above problem, the invention provides a kind of metal hydride hydrogen supercharging device of simple to operate, heat self-balancing, comprise metal hydride compression unit, heat exchange unit, control unit, metal hydride compression unit is two or more, heat exchange unit is wrapped in metal hydride compression unit outer wall, is realized the automatic operation of metal hydride hydrogen supercharging device by control unit.
Rare Earth, titanium system or magnesium microalloying are filled in metal hydride compression unit inside, and hydrogen stores in solid form.
Heat exchange unit is electric heating cover, is wrapped in metal hydride compression unit outer wall, homogeneous heating, can sets temperature within the scope of 0 ~ 1000 DEG C, and keep constant temperature.
Have return flow line between metal hydride compression unit, the hydrogen that can control in rear stage metal hydride compression unit is back to the metal hydride compression unit of previous stage, and the hydrogen in first order metal hydride compression unit is back to hydrogen source.
Control unit regulation and control heat exchange unit temperature, heating time, the input of monitoring metal hydride compression unit, output flow and pressure.
Automatically supercharging is controlled by following process implementation.
Metal hydride compression unit inhales hydrogen at a lower temperature, inhale hydrogen saturated after, setting high-temperature heating, metal hydride compression unit releases high pressure hydrogen, when monitor put hydrogen pressure not enough time, stop exporting hydrogen, heat exchange unit stops heating simultaneously; Now make metal hydride compression unit continue to put hydrogen, and circulation drains into previous stage metal hydride compression unit and makes it inhale hydrogen, because hydrogen storage material puts hydrogen heat absorption, inside temperature is reduced to normal temperature rapidly, so can realize the quick switching of high/low temperature.Same, first order metal hydride compression unit realizes high/low temperature switching by hydrogen being back to hydrogen source.
Above all processes is controlled by control unit, automatically runs, simple to operate, and can solve the high temperature of electric heating cover own and change slow problem to low temperature, replaces traditional water bath, oil bath heat exchange, can simplified apparatus greatly, reduces potential safety hazard, improves stabilization of equipment performance.
Utilize this hydrogen supercharging device, supercharging is fast, efficiency is high, and system footprint is little, noiseless, cost squeeze are low, simple to operate, easy to maintenance, has good market application foreground.
