The device can hydrogenate not only a 35MPa fuel cell automobile but also a 70MPa fuel cell automobile when being filled, and the filling efficiency is much higher than that of the prior domestic construction and operation.
Before the container skid-mounted compression hydrogenation device for the hydrogenation machine runs, nitrogen supplied by a nitrogen source outside the skid forms two paths through a total purging pipeline 31: one way into the first purge conduit 32; the other path of the hydrogen passes through a total hydrogen pipeline 28 and a first hydrogen pipeline 29, sequentially passes through a primary compressor 9, a first heat exchanger 14, a buffer tank 15 to a secondary compressor 11, then sequentially passes through a second heat exchanger 17 and a buffer coil 22 to a hydrogenation machine 23 through a third hydrogen pipeline 30, and sweeps the whole hydrogen flowing pipeline and gas path component/equipment, so that the effects of drying and carrying away impurities are achieved.
When hydrogenation is carried out, the hydrogen flow path is as follows: the hydrogen supplied by the prying-out hydrogen source enters the primary compressor 9 through the total hydrogen pipeline 28 for heat exchange, temperature reduction and pressurization to a set value A, the hydrogen subjected to heat exchange, temperature reduction and pressurization by the primary compressor 9 is subjected to secondary heat exchange and temperature reduction by the first heat exchanger 14, the hydrogen enters the secondary compressor 11 through the buffer tank 15 for tertiary heat exchange, temperature reduction and pressurization to a set value B (B is larger than A), the high-pressure hydrogen subjected to heat exchange, temperature reduction and secondary pressurization by the secondary compressor 11 is subjected to four-time heat exchange and temperature reduction by the second heat exchanger 17, enters the hydrogenation machine 23 through the buffer coil 22, and is injected through the hydrogenation. The buffer tank 15 can eliminate pipeline vibration, reduce pressure pulse, reduce flow floating and protect downstream instruments and equipment.
When hydrogenation is carried out, the flow path of the refrigerant medium is as follows: the water pump 20 extracts the refrigerant medium in the water tank 19, and the refrigerant medium is respectively pumped into the first heat exchanger 14, the second heat exchanger 17 and the secondary compressor 11, and the refrigerant medium flowing into the first heat exchanger 14 indirectly exchanges heat with the hydrogen entering the first heat exchanger 14 to heat; the refrigerant medium flowing into the second heat exchanger 17 indirectly exchanges heat with the hydrogen gas entering the second heat exchanger 17 to heat up; the cold medium flowing into the secondary compressor 11 indirectly exchanges heat with the engine oil of the secondary compressor to heat up, then flows into the primary compressor 9 to indirectly exchange heat with the engine oil of the primary compressor 9 to heat up for the second time. The cold medium flowing out of the first heat exchanger 14, the second heat exchanger 17 and the primary compressor 9 is collected in the air cooler 18, is cooled by the air cooler 18 and then returns to the water tank 19, and then is continuously circulated in the flow path under the action of the water pump 20, so that a cold source for heat exchange is continuously provided for the first heat exchanger 14, the second heat exchanger 17, the secondary compressor 11 and the primary compressor 9.
When the gas circuit is in failure and a small amount of hydrogen is needed to be temporarily filled, the second normally open valve 7 is closed, the second normally closed valve 6 is opened, hydrogen supplied by an external hydrogen source is pried to enter the hydrogenation machine 23 through the total hydrogen pipeline 28, the first blowing pipeline 32 and the buffer coil 22, and temporary hydrogen filling is carried out through the hydrogenation gun.
