Embodiment：
During initial operation, by taking the methanol aqueous solution of allotment 60% as an example, it is assumed that need to allocate the combustion that weight is 50kg altogether
Material, therefore mixing system can calculate 50kg x 60%=30kg, the first stage will add 30kg methanol.Now methanol electromagnetism
Valve is opened, and methanol supply unit extracts outside methanol and entered in allotment bucket, stops when weight sensing component detects 30kg
Methanol is added, is fed afterwards into second stage.Now pure water magnetic valve starts, and water purification machine starts is converted to pure water by running water
Add afterwards in allotment bucket, simultaneously, allotment magnetic valve and mixing pump will start, as being pre-mixed function.Until list of weighing
After member detects 50kg, stop adding pure water, and continue mixing 5 minutes, even if allotment is completed.After allotment is completed, if storage
Liquid level detecting device instruction low liquid level in bucket, fuel will be extracted from allotment bucket until liquid level detecting indicates high level.So by adjusting
Fuel is extracted to storage barrel with bucket, until allotment bucket weighs less than setting value, will be entered and be allocated next time again, so repeat to follow
Ring.
When needing the methanol-water for different reformer allotment various concentrations, the weighing unit immediately below allotment bucket is surveyed
Measure after weighing less than a setting value in bucket (such as 2kg) and enter allotment flow, when input allotment numerical value be 60% methanol-water
When, computer it is respective to calculate remaining first alcohol and water automatically according to the ratio of last time allotment, and remaining methanol aqueous solution weight
Weight, if the ratio of last time allotment is 50%, remaining 2kg, remaining each 1kg of first alcohol and water, it is assumed that need to allocate weight altogether
For 50kg, now system accounting calculation 50kg x 60%-1kg=29kg, the first stage will add 29kg methanol.Now methanol
Magnetic valve is opened, and methanol supply unit extracts outside methanol and entered in allotment bucket, until weight sensing component detects 2+29=
Stop adding methanol during 31kg, fed afterwards into second stage, now pure water magnetic valve starts, and water purification machine starts running water
Be converted to and add in allotment bucket after pure water, at the same time, allotment magnetic valve will start with mixing pump, as being pre-mixed function.
After weighing unit detects 50kg, stop adding pure water, and continue mixing 5 minutes, even if allotment is completed.Allocate completion
Afterwards, if the liquid level detecting device in storage barrel indicates low liquid level, fuel will be extracted from allotment bucket until liquid level detecting indicates high level.
Fuel is so extracted to storage barrel by allotment bucket, until allotment bucket weighs less than setting value, will enter and allocate next time again, so
Repetitive cycling.
Only highly preferred embodiment of the present invention is described above, but is not to be construed as limiting the scope of the invention.This
Invention is not only limited to above example, and its concrete structure allows to change.All protection models in independent claims of the present invention
Interior made various change is enclosed to all fall in the scope of protection of the present invention.
