Description
Technical field
The present invention relates to a kind of method and device thereof that makes gas generating unit possess universal property, relate to a kind of method and device that can make liquid gas making device arbitrary overturn specifically.
Background technology
Because the hydrogen storage material sodium borohydride has the advantages such as hydrogen purity height of hydrogen-storage amount height, storage security, easy to use, environmental friendliness, generation, recently, sodium borohydride is used for very big interest and the further investigation that hydrogen supply device has caused people as the storage hydrogen carrier.
Traditional sodium borohydride hydrogen-manufacturing reactor, be with sodium borohydride solution and catalyzer contact reacts, generate sodium metaborate and hydrogen, comprise the reaction residue inflow reactor of sodium metaborate, unreacted sodium borohydride and water etc., hydrogen is discharged from the venting port that is positioned at the reactor upper end.If upset even inversion take place in reactor in the reaction process, waste liquid did not just overflow from venting port have the position of venting port when waste liquid after, cause follow-up hydrogen purification system paralysis, hydrogen can not normally be discharged and also can be caused reactor pressure to rise sharply, and has potential safety hazard.Publication number be CN101049907 patent disclosure a kind of device of borohydride hydrolytic hydrogen production, this device has two encloses containers, be connected by catheter, two encloses containers are respectively reaction zone vessel and storing district container, after reaction material in the storing district container enters reaction zone vessel by catheter, produce hydrogen under the catalysis of catalyzer, the hydrogen of generation is derived by airway again.This device can be realized the automatic control hydrogen supply, but the inversion in a single day of this device, the solution in the reaction zone vessel will flow out along airway, causes follow-up gas treating system or fuel cell system paralysis or impaired.For hydrogen generator, during especially as portable hydrogen supply, if can not overturn and the inversion meeting brings very big inconvenience to use.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of can make in gas generating unit arbitrary overturn, the umklapp process can normal exhaust and the method that can not overflow of waste liquid.
Another object of the present invention provides the gas generating unit that uses aforesaid method.
For solving the problems of the technologies described above, the present inventor has carried out a large amount of research and performing creative labour on the basis of existing technology, developed a kind of method that makes gas generating unit possess universal property, be the waste liquid of generation in the described gas generating unit and the mixture of gas, through water-absorbing material, waste liquid is adsorbed by described water-absorbing material, realizes gas-liquid separation.
Described water-absorbing material is a kind of or wherein several mixture in super absorbent resin, heat seal dust-free paper, sponge and sponge sucks in water the roller.
A kind of gas generating unit that uses aforesaid method comprises reaction tubes and waste liquid chamber, and described reaction tubes is located in the waste liquid chamber, the one end be located at the outside liquid-inlet pipe in waste liquid chamber and be connected, the other end is connected with inside, waste liquid chamber; Inside, waste liquid chamber is filled with water-absorbing material, also is provided with the air outlet on the wall of waste liquid chamber.
Described water-absorbing material is fluffy and the waste liquid chamber filled up.
Described water-absorbing material is a kind of or wherein several mixture in super absorbent resin, heat seal dust-free paper, sponge and sponge sucks in water the roller.
In traditional liquid gas making device, the realization of gas-liquid separation generally all is that pneumatic outlet is located at device top, and is different with density of liquid by gas, and gas density is little so can flow out from the pneumatic outlet on device top.Therefore this class device can not arbitrary overturn, inversion, in case be inverted, waste liquid will flow out from pneumatic outlet, influence the gas outflow.The present invention adopts a design cleverly, realizes gas-liquid separation with water-absorbing material, promptly after waste reaction solution and gas mixture flow go out, with water-absorbing material waste liquid is all absorbed, and gas is by bleeder behind the loose porous water-absorbing material.So just can make gas generating unit arbitrary overturn, inversion, can not influence the outflow of gas, make gas generating unit have universal property.
When gas generating unit of the present invention uses, reaction solution is injected in the reaction tubes from liquid-inlet pipe through pump, contact with catalyzer in the reaction tubes and to react, gas that generates and waste reaction solution flow out from the other end of reaction tubes, carry out gas-liquid separation through water-absorbing material in the waste liquid chamber, waste reaction solution is absorbed by water-absorbing material, after gas passes through loose water-absorbing material, the venting hole place that is provided with by the waste liquid chamber discharges, and enters subsequent process.The consumption of the water-absorbing material of filling in the waste liquid chamber can be decided according to the volume in what and waste liquid chamber of reaction back waste liquid amount, if generation waste liquid volume is big, then will increase the consumption of water-absorbing material accordingly; If the volume in waste liquid chamber is bigger,, also to increase the consumption of water-absorbing material accordingly in order to fill completely whole waste liquid chamber.In order better to realize the separation fully of gas-liquid, the water-absorbing material of filling generally will whole abrim cavity in waste liquid the chamber in, and for the outflow of the hydrogen of being more convenient for, filling is difficult for tension, the filling of loosening, and suitable gas flows through.Therefore how no matter the device of invention overturn, its gas-liquid separation process is all as described above, as long as water-absorbing material does not reach capacity, waste liquid will be absorbed by water-absorbing material fully, can not flow out, therefore how the device of no matter inventing overturns, and can realize the normal hydrogen supply of whole process, can satisfy the requirement of mancarried device to hydrogen supply equipment.
