The temperature of case, and show the historical variations curve of these three position temperature；It is cold by the touch-screen setting circulation of control system
But the temperature of water, control system realize the control to circulating water cooling system power by pid control algorithm；It is by controlling
The heating-up temperature of the touch-screen setting electrically heated rod of system, control system realize the heating work(of electrically heated rod by pid control algorithm
The control of rate, the temperature of heated for controlling temperature when institute foundation are to be positioned over the temperature that the second temperature transducer of high-pressure bottle lower surface is surveyed
Degree；Cooling and ramp cycle of the control system realization to high-pressure bottle alternately control, so as to realize pressure hydrogen gas cylinder to high pressure
The supercharging of hydrogen cylinder is filling；The duration of hydrogen is inhaled to cooling by the touch-screen of control system and the duration of hydrogen is put in heating
Set, to ensure that hydrogen storage material has sufficiently long time suction hydrogen saturation and dehydrogenation abundant.
8. simple hydrogen gas single stage supercharging according to claim 1 purifies bulking system, it is characterised in that when in high-pressure bottle
Portion's pressure>During 15MPa, safety valve automatically opens up, and completes pressure release；When the pressure value of first pressure sensor<0.16MPa, entirely
Supercharging canning process terminates, and the system stalls, i.e. electrically heated rod stopping heating, magnetic valve return to the closing shape of acquiescence
State.
9. simple hydrogen gas single stage supercharging according to claim 2 purifies bulking system, it is characterised in that when passing through electrical heating
When rod is heated, control system is closed magnetic valve, so as to which cooling water path is truncated, avoids causing high pressure-volume
The surface cooling of device；When being cooled down by spray equipment to high-pressure bottle, control system stop to electrically heated rod power with
Stop heating.
10. the application method of the simple hydrogen gas single stage supercharging purification bulking system described in a kind of one of claim 1 to 9, it is special
Sign is that the workflow of simple hydrogen gas single stage supercharging purification bulking system is divided into cooling suction hydrogen and two processes of hydrogen are put in heating；
Wherein,
(1) hydrogen is inhaled in cooling includes below scheme：
Control system sends instruction unpack magnetic valve, and the cooling water in circulating water machine enters in spray equipment, and cooling water is from spray
Nozzle in shower device is sprayed, and is injected in the surface of high-pressure bottle, and it is cooled down, makes the temperature of high-pressure bottle rapid
Reduce；With the reduction of high-pressure bottle internal temperature, spherical composite hydrogen storage material starts to inhale hydrogen, causes the hydrogen inside high-pressure bottle
Atmospheric pressure decreases；When the Hydrogen Vapor Pressure in high-pressure bottle is less than the pressure of pressure hydrogen gas cylinder, first check-valve is beaten automatically
Open, for hydrogen by being flowed into pressure hydrogen gas cylinder in high-pressure bottle, the spherical composite hydrogen storage material in high-pressure bottle persistently inhales hydrogen, when the
Change of the pressure value of one pressure sensor in 1 minute<During 0.05MPa, that is, think that high-pressure bottle has inhaled hydrogen saturation；Control system
Thus system sends instruction and closes magnetic valve, spray equipment stops spray cooling water, and high-pressure bottle is inhaled hydrogen and terminated；
(2) hydrogen is put in heating includes below scheme：
Control system sends instruction and starts electrically heated rod, realizes the heating to high-pressure bottle, control system passes according to the second thermometric
The heating power of the real-time adjust automatically electrically heated rod of temperature value and pid algorithm of sensor, with the progress of heating, high-pressure bottle
Internal temperature constantly raises, and the spherical composite hydrogen storage material inside high-pressure bottle starts to be pressurized dehydrogenation, the hydrogen pressure of high-pressure bottle
Power also constantly rise therewith；When the Hydrogen Vapor Pressure of high-pressure bottle is more than the pressure of pressure hydrogen gas cylinder, first check-valve is closed automatically
Close, prevent the hydrogen of high-pressure bottle to be back in pressure hydrogen gas cylinder, when the Hydrogen Vapor Pressure of high-pressure bottle is more than High Pressure Hydrogen gas cylinder
During pressure, second check-valve is automatically opened up, and hydrogen is entered in High Pressure Hydrogen gas cylinder by high-pressure bottle；With the type discharge of high-pressure bottle
Hydrogen, when the pressure value of second pressure sensor changed in 1 minute<During 0.05MPa, that is, think that high-pressure bottle fill by dehydrogenation
Point；Thus control system sends instruction stopping electrically heated rod and continues to heat, the internal temperature of high-pressure bottle is gradual, therewith hydrogen pressure
Power also gradually reduces；When the Hydrogen Vapor Pressure of high-pressure bottle is less than the Hydrogen Vapor Pressure of High Pressure Hydrogen gas cylinder, second check-valve is closed automatically
Close, to avoid hydrogen in High Pressure Hydrogen gas cylinder from being back in high-pressure bottle；Now, the heating of high-pressure bottle is put hydrogen process and terminated.
