The outlets of the first diffusing pipeline 701, the second diffusing pipeline 702, the third diffusing pipeline 703, the fourth diffusing pipeline 704 and the fifth diffusing pipeline 705 are converged and then diffused in a centralized manner. Normally, the opening pressures set by the first relief valve 29, the second relief valve 30, the third relief valve 37 and the fourth relief valve 41 are not all the same, and in actual operation, the respective set opening pressure values are set according to system requirements.
In this embodiment, the second normally open valve 28, the third normally open valve 31, the fourth normally open valve 36 and the fifth normally open valve 40 are all lock-open valves which are opened and closed by controlling the valves with keys.
To further ensure the safety performance of the device, the present embodiment is provided with a low pressure filter 8 on the total hydrogen pipe 501 between the first pneumatic valve 7 and the air inlet of the primary compressor 9. At this time, one end of the fourth hydrogen pipe 507 is connected to the side wall of the total hydrogen pipe between the first pneumatic valve 7 and the low pressure filter 8, and is communicated with the total hydrogen pipe 501. A high-pressure filter 16 is provided on the first hydrogen gas pipe 502 between the buffer tank 15 and the intake of the secondary compressor 11. At this time, the fifth blow-off line 705 is located on the first hydrogen line 502 between the buffer tank 15 and the high-pressure filter 16. Impurities in the hydrogen gas are removed as much as possible by double filtration through the low-pressure filter 8 and the high-pressure filter 16, and the purity of the hydrogen gas is further improved.
The compression hydrogenation device for the hydrogenation machine further comprises an electric control cabinet with a control system, wherein a plurality of pressure measurement elements are arranged on a gas pipeline system, and the control system is connected with a compressor oil pressure measurement element, a hydrogenation machine internal control system and each pressure measurement element, a first pneumatic valve 7, a second pneumatic valve 35, a third pneumatic valve 39, a fourth pneumatic valve 32 and a fifth pneumatic valve 33 on the gas pipeline system. As shown in fig. 6 (the diagrams in fig. 7, 8, 9 and 10 are spliced to form a completed flow chart shown in fig. 8), the control system can control the opening and closing of the first pneumatic valve 7, the second pneumatic valve 35, the third pneumatic valve 39, the fourth pneumatic valve 32 and the fifth pneumatic valve 33, respectively, according to the compressor oil pressure, the hydrogenation machine operating state and the gas piping system pressure. The specific control process is as follows:
as shown in fig. 4, 6 and 7, the start-up device determines whether the oil pressures of the two compressors (the first-stage compressor 9 and the second-stage compressor 11) are lower than a set value through a control system in the electric control cabinet, and if the oil pressures of the two compressors are lower than the set value, the light load mode is started: the control system controls the first air-operated valve 7 to be closed, the fourth air-operated valve 32 to be opened, the fifth air-operated valve 33 to be closed, the second air-operated valve 35 to be closed, and the third air-operated valve 39 to be closed. At this time, the hydrogen gas between the first and second air-operated valves 7 and 35 enters the cycle: the hydrogen sequentially passes through the primary compressor 9, the first heat exchanger 14, the buffer tank 15, the secondary compressor 11 and the second heat exchanger 14 and then returns to the primary compressor 9 again, and the circulation is repeated until the oil pressure of the two compressors is built up. After a typical three minute cycle, the device enters run mode. If the oil pressure of the two compressors is not lower than the set value, the running mode is directly entered.
Upon entering the running mode, as shown in fig. 4, 6, and 8, the control system controls the first air-operated valve 7 to be opened, the fourth air-operated valve 32 to be closed, the fifth air-operated valve 33 to be closed, the second air-operated valve 35 to be opened, and the third air-operated valve 39 to be opened. At this time, the hydrogen gas passes through the first air-operated valve 7, the primary compressor 9, the first heat exchanger 14, the buffer tank 15, the secondary compressor 11, the second heat exchanger 14, the second air-operated valve 35, the second check valve 21, and the third air-operated valve 39 in this order, returns to the first air-operated valve 7 again, and enters a circulation state. If the hydrogenation machine 23 does not send out the hydrogenation signal, the circulation state is always kept, and if the hydrogenation machine 23 sends out the hydrogenation signal, the hydrogenation mode is entered.
When the hydrogenation mode is entered, as shown in fig. 4, 6, and 9, the control system controls the first air-operated valve 7 to be opened, the fourth air-operated valve 32 to be closed, the fifth air-operated valve 33 to be closed, the second air-operated valve 35 to be opened, and the third air-operated valve 39 to be closed, based on the signal output from the hydrogenation unit 23. At this time, the hydrogen gas passes through the first air-operated valve 7, the primary compressor 9, the first heat exchanger 14, the buffer tank 15, the secondary compressor 11, the second heat exchanger 14, the second air-operated valve 35, and the second check valve 21 in this order, and enters the hydrogenation unit 23 to be added.
After hydrogenation is completed, the control system judges whether the operation is stopped or not, and if the operation is not stopped, the operation is circulated to the operation mode again; and if the machine is stopped, entering a stop mode.
When the stop mode is entered, as shown in fig. 4, 6 and 10, the control system controls the first air-operated valve 7 to be closed, the fifth air-operated valve 33 to be opened, the second air-operated valve 35 to be closed, and the third air-operated valve 39 to be closed, and the two compressors stop operating. At this time, the high-pressure hydrogen gas in the gas piping system is discharged from the third discharge pipe 703 through the fifth air-operated valve 33, the fifth check valve 34. When the hydrogen pressure in the gas piping system decreases to the set value, the fourth pneumatic valve 32 is opened, and the inlet pressure and the outlet pressure of the primary compressor 9 and the secondary compressor 11 are also discharged together.
