The metal hydride hydrogen-pressurizing device with the full-automatic multi-stage compression function comprises two or more metal hydride compression units, a heat exchange unit and a control unit. The metal hydride compression units are arranged inside the heat exchange unit, the pressure, flow and temperature of a system are detected through the control unit, and thus automatic operation of the metal hydride hydrogen-pressurizing device is achieved. The metal hydride hydrogen-pressurizing device with the full-automatic multi-stage compression function is small in occupied space, free of noise, low in compression cost, easy to operate and convenient to maintain, has a hydrogen purification function, is an economical and efficient hydrogen compressor product, and can replace a traditional mechanical compressor.
Description
Technical field
The present invention relates to a kind of method of hydrogen compression, puts at a lower temperature hydrogen platform and press relatively low using metal hydride, the higher principle of hydrogen platform pressure is put at relatively high temperatures, reach the purpose of hydrogen pressurization.
Background technology
According to macroscopic property, metal hydride puts hydrogen pressure variation with temperature and follows Van ' t Hoff equations：lnPd=△H0/RT-△S0/ R, wherein, Pd is to put hydrogen balance pressure, △ H0With △ S0For the enthalpy change and Entropy Changes of reaction.
After hydrogen bearing alloy inhales hydrogen saturation under lower temperature and lower pressure, metal hydride temperature is increased to into higher temperature, now metal hydride will release the hydrogen of high pressure.Metal hydride hydrogen compressor is different according to the hydrogen storage material for selecting i.e. using the characteristic work of hydrogen bearing alloy, is capable of achieving different degrees of pressurized effect.
In the market ripe hydrogen compressor is mechanical compressor, this compressor typically all needs multi-stage booster to reach elevated pressures because of the restriction of compressed ratio, there is the shortcomings of volume is big, weight is heavy, power consumption is high, and a certain degree of reduction hydrogen purity of meeting, also need to set up hydrogen purification equipment.
Metal hydride hydrogen compressor compact conformation, substantially, hydrogen purity is unaffected, has great application prospect for pressurized effect.At present the metal hydride hydrogen compressor of exploitation mostly is single stage compress, and pressurized effect is limited, and is all that, by artificial operation, the regulation because being related to temperature, pressure etc., operation is complex, and its popularization and application is very restricted.
The content of the invention
For problem above, the present invention provides a kind of metal hydride hydrogen pressurizer simple to operate, Automated condtrol operation, including metal hydride compression unit, heat exchange unit, control unit, metal hydride compression unit is two or more, metal hydride compression unit is placed in inside heat exchange unit, and by control unit the automatic running of metal hydride hydrogen pressurizer is realized.
Metal hydride compression unit inside filling Rare Earth, titanium system or magnesium microalloying, hydrogen is stored in solid form.
Heat exchange unit interior media is one kind of water, oil, paraffin or fused salt.
Control unit regulates and controls temperature, the temperature control time of heat exchange unit, monitors the input of metal hydride compression unit, the flow of output and pressure.
Using the hydrogen pressurizer, hydrogen compressed efficiency is greatly improved, it is low, simple to operate, easy to maintenance and with hydrogen purification function to take up an area little, noiseless, cost squeeze, be a kind of hydrogen compressor product of economical and efficient, alternative traditional mechanical formula compressor.
