Specific embodiment
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
In the present invention, hydrogen energy supplied equipment includes tube bank vehicle, and tube bank vehicle being capable of Hydrogen Energy of the transport pressure within 20MPa
Source supplies hydrogen energy source for hydrogenation stations.Surge flask in hydrogenation stations is three groups or more, and for three groups, each group of surge flask is full
It is all 45Mpa when filling, but all buffers the Hydrogen Energy source gas for there are different pressures after gas supply, when to hydrogenation plant (such as bus)
When requiring supplementation with fuel, according to the current pressure of hydrogen storage bottle in bus, the surge flask of corresponding pressure difference is selected to fill bus, big
Bar the lower situation of hydrogen storage bottle current pressure under, tube bank vehicle hydrogen energy source directly can also be supplied to bus.
Embodiment one
With reference to Fig. 1, a kind of supply method of hydrogenation stations hydrogen energy source, including step are present embodiments provided：
S10：Obtain the pressure in hydrogen energy supplied equipment and the pressure in multiple groups surge flask；
S20：Pressure in the hydrogen energy supplied equipment is compared with the pressure in the multiple groups surge flask, is obtained
Multiple groups pressure difference ratio；
S30：Judge whether the multiple groups pressure difference has than in lower than preset pressure ratio, if so, setting by adjusting compression
Hydrogen energy source compression in the hydrogen energy supplied equipment is filled into corresponding surge flask to store by standby control logic.
Single-stage compressor and the surge flask for buffering hydrogen energy source, single-stage pressure are provided in the present embodiment, in hydrogenation stations
The pressure capability of contracting machine is limited by compression ratio, is restrained vehicle as hydrogen energy supplied equipment, can be transported hydrogen energy source and be supplied to
Entire hydrogenation stations can also fill hydrogen when pressure is enough for vehicle, and compressor, which passes through, will restrain interior hydrogen energy source compression
Boosting, fills in surge flask, and the pressure threshold of surge flask is 45MPa, when vehicle carries out plus when hydrogen, by surge flask and
The pressure difference of automobile hydrogen storage bottle, to fill hydrogen.
It is to be understood that the pressure threshold of surge flask can also be 90MPa, it is the car that operating pressure is 70MPa
Add hydrogen.
Hydrogen energy supplied equipment in step S10 is for restraining vehicle, and pressure is 20MPa to tube bank vehicle in a fully loaded state,
After persistently supplying hydrogen to hydrogenation stations, pressure will slowly be lower.
Multiple groups surge flask is at least three groups or three groups or more, for three groups, including low pressure buffer bottle group, middle pressure surge flask
Group, high-pressure buffer bottle group.
The present embodiment further includes step：
S00：Pressure in multiple groups surge flask is adjusted, the pressure in each group surge flask group is kept to be in difference
Pressure limit.
Work is not started in hydrogenation stations, when not carrying out adding hydrogen to vehicle, the gas pressure in each group surge flask group is all
It is identical, and when starting to carry out vehicle to add hydrogen, control each group surge flask group adds hydrogen sequence, so that gas in each group surge flask group
Body storage capacity is different, and the gas pressure in each group surge flask group is also different.Wherein, the pressure of high-pressure buffer bottle group is high
It is higher than low pressure buffer bottle group in the pressure of middle pressure surge flask group, middle pressure surge flask group.That is, the gas pressure in each group of surge flask
It can control within the scope of different pressures.
In step S20, vehicle is restrained while constantly providing hydrogen source for multiple groups surge flask, gas pressure is also corresponding
Decline, and multiple groups surge flask is for vehicle when carrying out adding hydrogen, gas pressure can also reduce, by carrying out pair the pressure of the two
Than obtaining multiple groups pressure difference ratio, entering back into step S30.
In step S30, preset pressure ratio is defined according to the compression ratio of compressor, in order to adequately reduce tube bank
The recycling overbottom pressure of vehicle, such as the recycling overbottom pressure for restraining vehicle is controlled in 1MPa, when the compression ratio of compressor is five, then can only
The interior hydrogen energy source of tube bank is compressed within 5MPa, i.e., preset pressure ratio is lower than 5.
When multiple groups pressure difference than in there are lower than preset pressure ratio, then according to the correlation data in step S20, find phase
The surge flask group answered, meanwhile, which is also the surge flask group that gas pressure is minimum in all surge flask groups, so that compression
The interior hydrogen energy source compression of tube bank can be also filled into the surge flask group under the limitation of compression ratio by machine.
By the way that the surge flask group of multiple groups different pressures is arranged, pressure classification is carried out, so that single-stage compressor can adapt to
The limitation of compression ratio avoids the demand to super-high pressure compressor, while also can adequately compress the interior hydrogen energy source of tube bank
Into the lower surge flask group of pressure, the recycling overbottom pressure of tube bank vehicle is reduced, improves the conevying efficiency of tube bank vehicle.
The present embodiment further includes step：
S31：Judge the surge flask group for whether thering is pressure to be lower than the pressure limit in the multiple groups surge flask group, if so,
The hydrogen energy source compression in the lower surge flask group of other pressure is then filled by the surge flask group by compressor.
As each group surge flask group is constantly that vehicle fills hydrogen energy source, gas reserves tail off accordingly, gas pressure
It will decline, and in order to keep the gas pressure organized in each group surge flask to be still within the pressure limit in step S00, it needs
Hydrogen energy source is compressed by compressor is supplemented to corresponding surge flask group.
It wherein,, can not since compressor is limited by compression ratio when the gas pressure decline in high-pressure buffer bottle group
When the hydrogen compression that tube bank interior pressure is lower than setting value is filled into high-pressure buffer bottle group, need to select from other surge flask groups
The surge flask group lower than the high-pressure buffer bottle group pressure is selected as hydrogen source, compression ratio is just able to satisfy, keeps compressor lower from pressure
Surge flask group in hydrogen energy source compression be filled into high-pressure buffer bottle group.
It is in different pressure limits by controlling to adjust multiple groups surge flask group, it can be according to current in vehicle hydrogen storage bottle
Pressure come to select suitable surge flask group be that vehicle adds hydrogen, can be flexible and convenient operate, meanwhile, reduce to compressor
The requirement of compressed capability reduces compressor cost.
The present embodiment further includes step：
S40：Judge whether the pressure value of the hydrogen energy supplied equipment is lower than preset pressure threshold value, if so, to described
Hydrogen energy supplied equipment fills hydrogen energy source.
In step S40, preset pressure threshold definitions are the recycling overbottom pressure for restraining vehicle, when the interior gas pressure value of tube bank is low
When recycling overbottom pressure, the interior hydrogen energy source compression of tube bank cannot be filled into surge flask by compressor again, at this point, tube bank vehicle can be with
Other hydrogen make station hydrogen make-ups such as gas supplier are returned to, hydrogenation stations is continued as later and hydrogen energy source is provided.
