Operation principle of the present utility model is as follows：
Fig. 8 is that a kind of quick hydrogen manufacturing course of work for starting self-heating type preparing hydrogen by reforming methanol microreactor of the present embodiment is former
Reason figure.Before hydrogen production reaction starts, protection gas nitrogen is passed through into microreactor, in order to remove the residual air in passage.Nitrogen
Flow controlled by mass flowmenter.Then, air is passed through into the combustion material air flow passage of microreactor from air pump,
From flow pump methanol liquid is passed through into combustion material methanol mobile passage.Air passes through air intake stainless steel tube 10, first
Combustion material air inlet port 12 flows into methanol oxidation combustion chamber.Burning fuel methanol passes through methanol inlet stainless steel tube 9, first
Combustion material methanol inlet hole 13, the second combustion material methanol inlet hole 15, the 3rd combustion material methanol inlet hole 16 flow into the
In the microchannel 22 of dimethanol burner plate 5, then the manhole 21 for the methanol burning porous plate 4 for passing through the top of microchannel 22
Array flows into methanol oxidation combustion chamber.Catalyst combustion reaction is carried out after methanol and air contact, and (product is carbon dioxide after burning
With water etc.), provide heat for reactor.Microreactor is warming up to 230 DEG C using heat caused by catalysis burning；Work as reactor
When temperature is warming up to 230 DEG C, it is passed through into microreactor containing H2The N of volume fraction 5%2/H2Mixed gas, to methanol recapitalization system
Hydrogen catalyst is reduced.After the completion of microreactor reduces first, microreactor can carries out reformation hydrogen production reaction always.
In the case where no outside air aoxidizes, without being reduced again.
When microreactor needs reformation hydrogen production to run, the methanol fuel inlet flow rate of methanol oxidation combustion chamber is adjusted, will
Reactor is rapidly heated and adjusted to reformation hydrogen production reaction temperature.Then, fuel reforming (mixed solution of such as methanol-water) is in pump
The fuel reforming flowing passage of microreactor is pumped under driving Deng power source, preparing hydrogen by reforming methanol course of reaction is carried out, is made
The gases such as hydrogen, carbon dioxide, carbon monoxide.In hydrogen production process, the temperature of microreactor is controlled by thermocouple and temperature controller,
The flow of fuel reforming is controlled by flow pump or fluid flowmeter, and the pressure of hydrogen production process is monitored by pressure transmitter.
The utility model can be used as medium and small hydrogen manufacturing to equip, applied to mobile hydrogen fuel cell hydrogen source.
The present embodiment is separately supplied burning fuel methanol and air by improving microreactor structure, the microreactor
Burning fuel methanol and air are separately supplied.Because burning fuel methanol and air flow in two single passages, drop
Air velocity when low fuel contacts with catalyst, this is just improved the supply of methanol and air, adds micro- anti-
Answer the toggle speed of device.Second because the present embodiment air contacts with methanol is that gas flowing time-division section contacts in reaction channel
, this just can both have been avoided Inlet Fuel amount big, caused by reacting acutely the problems such as localized hyperthermia, can also homogenize micro- reaction
Device burning gallery temperature, improve efficiency of combustion and catalyst life.Made on the reformation hydrogen production plate of 3rd the present embodiment microreactor
The non-uniform micro-boss array structure of mistake row for making heat and mass efficiency high, the hydrogen production efficiency of microreactor can be effectively improved.Phase
Than can further improve fuel micro- anti-in the micro-boss array structure of parallel and wrong row, the non-uniform micro-boss array structure of mistake row
The residence time in device is answered, improves the heat and mass transfer performance of microreactor, so as to improve the efficiency of microreactor.4th
The core component (catalysis burner plate and the second methanol burner plate) of embodiment microreactor can use the micro- thixotropic forming work of semisolid
Skill is process, and manufacture efficiency is high, and processing cost is low.5th the present embodiment microreactor is compact-sized, in can be used for, small-power
Hydrogen manufacturing occasion.And scale is easily enlarged, several reactors need to be only laminated and hydrogen can be achieved in design entry runner
The expansion of yield.
