Embodiment
Fig. 1 is the structure chart that is applicable to the modular hydrogen EGR of fuel cell car.
As shown in the figure, hydrogen EGR 10 comprises: to being recycled to the residual gas pressurization of fuel cell pack 2, and with by hydrogen gas tank 1 supply, the injector module 11 of mixing mutually with hydrogen of the hydrogen line 3 of flowing through; And, in fuel cell pack 2 rear end branches, and be connected with flow valve 4 rear ends of controlling by hydrogen gas tank 1 supply of hydrogen amount, form the re-circulation line 13 of residual gas flow path.
Above-mentioned injector module 11 is arranged on the rear end of controlling by the flow valve 4 of hydrogen gas tank 1 supply of hydrogen amount.
Above-mentioned injector module 11 is by by the pressurization of nozzle and diffuser structure, and to high pressure (10bar) hydrogen injection of hydrogen gas tank 1 supply, improves the injector 11a of pressure hydrogen pressure; Utilize high-speed motor to improve the air blast 11b of the pressure hydrogen pressure of rotary blade; The inside line of return 12 that forms the closed-loop path between the outlet of injector 11a and entrance is installed after air blast 11b to be formed.
In the present embodiment, the suction of above-mentioned air blast 11b is arranged to be enough to and will flows out from injector 11a outlet, the air-flow that flows into fuel cell pack 2 converts the degree of the inner line of return 12 to.
But after the above-mentioned inner line of return 12 was set up closed valve, injector 11a outlet both can be communicated with re-circulation line 13, also can be communicated with hydrogen line 3.
Above-mentioned closed valve is controlled by controller.
As mentioned above, use closed valve can enlarge the scope that air blast 11b specification is selected.
In addition, above-mentioned re-circulation line 13 has the layout that is connected to injector module 11 entrances from fuel cell pack 2 rear ends.
Hydrogen EGR in the present embodiment, the controller of controlling by management recirculation moves, and utilizes applicable automobile controller to control general-utility car.
An example as above-mentioned controller control logic, if the regional control logic of underload (low discharge), open closed valve, make the recycle gas that once pressurizes by injector 11a reception carry out secondary pressurized by air blast 11b, and again return injector 11a, and connect injector 11a outlet and re-circulation line 13; If closed valve is moved, closed to the regional control logic of high load capacity (high flow capacity) by the machine 11b that turns off the blast, be communicated with injector 11a outlet and hydrogen line 3.
Fig. 2 (a) is the running status in hydrogen EGR underload (low discharge) zone.
As shown in the figure, if hydrogen EGR 10 at underload (low discharge) area operation, the residual gas of fuel cell pack 2 rear ends ejections is supplied to injector module 11 entrances by re-circulation line 13.
The residual gas that is supplied to above-mentioned injector module 11 porch enters injector 11a, and the residual gas that enters injector 11a sprays from the exit after once being pressurizeed through injector 11a inside.
But, if after air blast (11b) operation, the impeller suction is in injector 11a exit, can't arrive at fuel cell pack 2 from a gas-pressurized of injector 11a exit ejection, can only be sucked into the inner line of return 12.
At this moment, air blast 11b keeps only utilizing the suction just can be with the minimum rotation number of the line of return 12 that absorb through the gas that once pressurizes.
Opposite, if the inner line of return 12 is equipped with closed valve, can utilizes above-mentioned closed valve to cut off and be connected to the hydrogen line 3 of fuel cell pack 2, and open the inner line of return 12, do not need to limit the minimum rotation number of air blast 11b.
As mentioned above, by an absorb gas-pressurized of the line of return 12 of air blast 11b suction, again be supplied to injector 11a entrance after again pressurizeing by air blast 11b, injector 11a outlet can spray through once, the relatively high gas of pressure after secondary pressurized.
Then, the secondary pressurized gas of the above-mentioned injector 11a of ejection is supplied to fuel cell pack 2 by hydrogen line 3.
In the present embodiment, the suchlike secondary pressurized that is undertaken by air blast 11b can be from underload (low discharge) zone extends to load (middle flow) zone, the criterion in centering load (middle flow) zone is that air blast 11b carries out to residual gas the starting point that performance is returned in fully pressurization.
In fact, the standard in centering load (middle flow) zone is along with the variation of air blast 11b specification changes.
Simultaneously, Fig. 2 (b) is the running status in hydrogen EGR high load capacity (high flow capacity) zone.
As shown in the figure, if hydrogen EGR 10 at high load capacity (high flow capacity) area operation, the residual gas that flows out from fuel cell pack 2 rear ends is supplied to the porch of injector module 11 by re-circulation line 13.
The residual gas that is supplied to above-mentioned injector module 11 porch will flow into injector 11a, and the residual gas that flows into injector 11a flows out from the exit after through injector 11a internal pressurization.
At this moment, air blast 11b does not move, and the gas-pressurized from injector 11a exit outflow is supplied to fuel cell pack 2 by hydrogen line 3 thus.
If the inner line of return 12 is equipped with closed valve, above-mentioned closed valve can be cut off the inner line of return 12 and open hydrogen line 3, is converted to the state that injector 11a outlet and hydrogen line 3, fuel cell pack 2 are interconnected.
This is because in the situation that not through air blast (11b) pressurization, only still can realize pressurizing performance giving full play in high load capacity (high flow capacity) zone by injector (11a) pressurization.
Particularly, can not satisfy recirculating mass even can solve at the regional air blast 11b of operation to greatest extent of high load capacity (high flow capacity) by These characteristics, but cause the shortcoming problem of the low serial mixed power mode of recirculation performance; And can also reduce consumption of power by the machine 11b operation that turns off the blast.
As mentioned above, the hydrogen EGR 10 that the present embodiment relates to, by in injector 11a branch (to the injector from the residual gas pressurization of fuel cell pack 2 recirculation) and reconnect injector 11a, the re-circulation line 13 that be equipped with simultaneously injector module 11 that the inside line of return 12 of air blast 11b forms, is connected to injector module 11 from fuel cell pack 2 rear ends forms.During operation, if underload (low discharge) zone can be carried out pressurized treatments twice by injector 11a and air blast 11b, if high load capacity (high flow capacity) zone only utilizes injector 11a pressurization, both reduced the power consumption that the air blast operation causes, also reduced noise, particularly by the modularization of injector 11a and air blast 11b, reduced amount of parts, and realized the optimization of layout.
The above is only preferred embodiment of the present invention, is not for limiting protection scope of the present invention.
