Description
Technical field
The present invention relates to Hydrogen Technology fields, more particularly, are related to a kind of highly effective hydrogenation method and system.
Background technique
Hydrogen energy source has obtained the generally pass of countries in the world as " carbon-free " energy of a kind of efficient, cleaning, sustainable development
Note, the field of traffic based on hydrogen cell automobile is one of important directions of hydrogen utilization.Hydrogen Energy is restricted at this stage to hand over
Logical field is mainly the construction of hydrogenation stations using the bottleneck of development, adds hydrogen infrastructure insufficiency, becomes current China's Hydrogen Energy industry
Develop the maximum obstruction faced.
The source of hydrogenation stations hydrogen is divided into outer hydrogen supply and two class of interior hydrogen manufacturing of standing.Currently, the hydrogen filling pressure of hydrogenation stations has
Two kinds of 35MPa, 70MPa.
The process system process at conventional hydro station is substantially as shown in Figure 1 and Figure 2:
As shown in Figure 1, the hydrogen through 1 ' output of hydrogen manufacturing equipment for purifying in standing is temporarily stored into 2 ' of surge tank, set through hydrogen compression
(45 or 87.5MPa is such as pressurized to) after standby 3 ' (compressor or pump) pressurization, is separately stored in hydrogen storage bottle group through 7 ' of valve, 8 ', 9 '
In 4 '.4 ' of hydrogen storage bottle group is made of multiple hydrogen storage bottles, and is artificially divided into three kinds of grade hydrogen storage bottles of high, medium and low voltage (its is specified
Hydrogen storage pressure is consistent).
As shown in Fig. 2, the hydrogen transported through 11 ' of hydrogen long-tube trailer, after the 12 ' discharging of hydrogen device for discharging,
(45 or 87.5MPa is such as pressurized to) after 3 ' of hydrogen compression device (compressor or pump) pressurization, is stored up respectively through 7 ' of valve, 8 ', 9 '
It is stored in 4 ' of hydrogen storage bottle group.4 ' of hydrogen storage bottle group is made of multiple hydrogen storage bottles, and is artificially divided into three kinds of grades of high, medium and low voltage
Hydrogen storage bottle (its specified hydrogen storage pressure is consistent).
When by adding 5 ' of hydrogen machine to fill hydrogen to 6 ' of terminal user, 3 ' of hydrogen compression device stops transport, and is stored up first by low pressure
Hydrogen bottle is through 9 ' of valve, 10 ' and 5 ' of hydrogen machine is added to add hydrogen to 6 ' of terminal user, after the two pressure balance, if 6 ' hydrogen of terminal user
Pressure does not reach requirement (such as 35 or 70MPa), then continues to switch to middle pressure hydrogen storage bottle through 8 ' of valve, 10 ' and add 5 ' of hydrogen machine to end
6 ' of end subscriber adds hydrogen and to pressure balance, is eventually switched to high-pressure hydrogen storing bottle through 7 ' of valve, 10 ' and adds 5 ' of hydrogen machine to terminal user
6 ' add hydrogen to pressure balance, and the hydrogen charge pressure of 6 ' of terminal user is finally made to reach required value (such as 35 or 70MPa).
With the consumption of hydrogen in 4 ' of hydrogen storage bottle group, pressure constantly declines.When the Hydrogen Vapor Pressure in high-pressure hydrogen storing bottle is low
When a certain minimum pressure requires, stop 4 ' of hydrogen storage bottle group to the gas supply for adding 5 ' of hydrogen machine.Because to when adding 5 ' hydrogen supply of hydrogen machine, hydrogen is
Successively from basic, normal, high pressure hydrogen storage bottle, when high-pressure hydrogen storing bottle pressure is lower than recommended minimum value, pressed in low, middle pressure hydrogen storage bottle
Power has also been lower than the recommended minimum value.Therefore, all hydrogen storage bottles in 4 ' of hydrogen storage bottle group are both needed to hydrogen make-up.
Start 3 ' of compression device at this time, extracts hydrogen producer in upstream station and export in surge tank or outer hydrogen supply long-tube trailer
Hydrogen is successively filled into each hydrogen storage bottle of 4 ' of hydrogen storage bottle group after being pressurized, until each hydrogen storage bottle pressure of 4 ' of hydrogen storage bottle restores
To required value (such as 45 or 87.5MPa).
By the above process it is found that hydrogen filling process system in conventional hydro station has the following problems:
(1) each hydrogen storage bottle rated operating pressure of 4 ' of hydrogen storage bottle group is all the same, but because being artificially divided into high, medium and low voltage
Three kinds of grades, and successively according to hydrogenated 5 ' of machine of sequence of basic, normal, high pressure hydrogen storage bottle to 6 ' multistage hydrogen supply of terminal user, it is each to store up
Hydrogen bottle usage degree is different, and (pressure drop is maximum in low pressure hydrogen storage bottle, and pressure drop is taken second place in middle pressure hydrogen storage bottle, and pressure drop is most in high-pressure hydrogen storing bottle
It is small).Just because each hydrogen storage bottle usage degree is different, in the design of conventional hydro station hydrogen storage bottle group, often by high, medium and low voltage hydrogen storage bottle
Consider by different quantity (as high: in: low=2:3:4)；
(2) because successively according to hydrogenated 5 ' of machine of sequence of basic, normal, high pressure hydrogen storage bottle to 6 ' hydrogen supply of terminal user, hydrogen supply pressure
Power is ascending, adds that hydrogen speed is slow, low efficiency；
(3) because the hydrogen of 4 ' of hydrogen storage bottle group fills mouth, hydrogen gas outlet is same port, when the 4 hydrogenated machine of ' of hydrogen storage bottle group
When 5 ' are supplied to 6 ' of terminal user, 3 ' of compression device can not then work, and the utilization rate of 3 ' of compression device is lower；
(4) when the Hydrogen Vapor Pressure of 4 ' of hydrogen storage bottle group is reduced to minimum pressure, 3 ' of compression device supplements hydrogen to 4 ' of hydrogen storage bottle group
When gas, it is difficult to realize while be terminal user's hydrogen supply；If straight to 6 ' of terminal user by hydrogenated 5 ' of machine of 3 ' of compression device at this time
Hydrogen supply is connect, adds that hydrogen speed is slow, low efficiency.
