Embodiment approach
[0046] The specific embodiment is as follows: the comparison circuit acquires the pipeline flow values of the third flowmeter 73 and the second flowmeter 72, and calculates the pipeline flow of the third flowmeter 73 minus the second flowmeter 72 difference and send the difference in pipe flow to the trigger circuit. The trigger circuit receives the pipeline flow difference information, if the difference reaches the threshold -5m 3 , the trigger circuit triggers the switch of the second solenoid valve 62 to open the second solenoid valve 62 so that the hydrogen oil in the hydrogenation device 2 flows to the hydrogen oil filling station 4 . When the pipeline flow difference is less than the threshold -5m 3 , the second solenoid valve 62 is closed. The control details between other flowmeters and solenoid valves are similar to this according to the relationship between the hydrogen oil outflow and inflow of the device, and will not be repeated one by one.

The application discloses a hydrogen oil transportation system, comprising: a hydrogen production device, a hydrogenation device, a hydrogen oil storage station, a hydrogen oil filling station, and a recovered oil storage station; wherein: the hydrogen oil storage station includes at least one hydrogen oil storage station An oil storage tank, the recovered oil storage station includes at least one recovered oil storage tank. The hydrogen oil in the hydrogen production device and the recovered oil storage station flows to the hydrogenation device, and the gaseous hydrogen is stored in the organic liquid through the catalytic hydrogenation reaction to form hydrogen oil; the hydrogen oil flows from the hydrogenation device to the hydrogen oil storage station It is stored, and then flows to the hydrogen fuel filling station. The hydrogen oil filling station removes hydrogen from the organic liquid through catalytic dehydrogenation reaction and uses it in the form of gaseous hydrogen; the dehydrogenated organic liquid flows to the recovery oil storage station as recovered oil, and then flows from the recovered oil storage station to the the hydrogenation unit. It realizes the connection between hydrogen oil production and hydrogen oil recovery, achieves a balance between supply and demand, and reduces the energy loss of traditional vehicle transportation.
Description
technical field [0001] This application relates to the field of hydrogen energy production and transportation, in particular to a hydrogen oil transportation system. Background technique [0002] As a green energy, hydrogen energy has received extensive attention in recent years. At present, the production and transportation of hydrogen energy are mainly in the form of gaseous hydrogen, which faces safety problems such as explosions during hydrogen transportation and storage. [0003] In order to solve the above problems, an organic liquid hydrogen storage technology has been developed in recent years, that is, gaseous hydrogen is stored in organic liquid through catalytic hydrogenation reaction to form hydrogen oil. Under normal temperature and pressure, hydrogen is stably stored in hydrogen oil liquid, which is convenient for transportation; when in use, hydrogen is extracted from organic liquid through catalytic dehydrogenation reaction, and used in the form of gaseous h...
