Description
Technical field
The utility model relates to a kind of hydrogen storage machine, belongs to storage, conveying and the compression technique area of hydrogen.
Background technique
Hydrogen is a kind of desirable clean fuel and following important secondary energy.The hydrogen storage of practical application at present and the mode of conveying mainly contain three kinds: i.e. high-pressure bottle storage hydrogen, liquid hydrogen tank storage hydrogen and the solid-state storage hydrogen of hydrogen storage material hydrogen storage machine.Outstanding advantage with the solid-state storage of hydrogen storage material hydrogen storage machine, conveying hydrogen is that Security is good, and unit weight storage hydrogen density is far above high-pressure bottle and liquid hydrogen tank.
The container of hydrogen storage materials such as metal hydride, complex hydrides or amino-compound being put into a band valve just can constitute a hydrogen storage machine.There is thermal effect in hydrogen storage material in the container in the process of inhaling, putting hydrogen, the thermal effect value is different different because of hydrogen storage material, is generally 20～180 kj/mol.Keep hydrogen storage material in the hydrogen storage machine suction, put carrying out smoothly of hydrogen, just must import heat or from hydrogen storage machine derivation heat to hydrogen storage machine.The metal hydride hydrogen storage material can produce volumetric expansion when suction hydrogen changes hydride into, specific volumetric dilatation is generally 10～25%, and efflorescence is micron-sized fine powder gradually; And amino-compound hydrogen storage materials such as complex hydrides hydrogen storage material such as sodium alanate, aluminium lithium hydride, lithium borohydride and lithium amide, amino magnesium are put in suction and are formed powder in the hydrogen process easily from agglomeration, and its activity is very high, can not contact steam, oxygen and air.
Problem is: on the one hand, because the thermal conductivity very poor (suitable) of hydrogen storage material powder itself with the thermal conductivity of glass, sandstone, can not be in time in hydrogen storage machine input heat or from the hydrogen storage machine quantity of heat given up, make that the hydrogen storage material temperature rise sharply raises when sucking hydrogen, the hydrogen storage material temperature significantly descends again during releasing hydrogen gas, causes speed for hydrogen absorbing and releasing slowly even stop; On the other hand, the good fluidity of hydrogen storage material fine powder, put in the hydrogen operating process in suction, because of can flowing, the reasons such as driving that are subjected to hydrogen flow form local excessive accumulation in hydrogen storage machine, cause container deformation or destruction, complex hydrides and amino-compound hydrogen storage material are put in suction and are also formed powder in the hydrogen process easily from agglomeration simultaneously, and suction hydrogen discharge reaction speed is slowed down.Therefore, effectively improve the temperature conductivity of powder in the hydrogen storage machine and prevent the flowing of powder, reunion and local excessive accumulation, need just to have become the key issue of solution.
