When the methanol water pressure regulating system works, the one-way valve 1 and the switch valve 2 are opened, mixed methanol water enters the methanol water pressurizing system from the methanol water inlet 6, flows through the one-way valve 1 and the switch valve 2 through the methanol water pipeline and then is sent to the booster pump 3 and the pressure relief valve 4, the pressure relief valve 4 is a flow regulating valve which regulates the pressure of the methanol water to keep the pressure of the methanol water in the system constant, then the methanol water is conveyed to the safety valve 5 through the methanol water pipeline, the pressure of the methanol water is detected through the pressure detecting unit before being sent to the safety valve 5, and when the pressure of the methanol water exceeds the pressure bearing limit of the methanol water pressurizing system, the safety valve 5 is opened and the excessive pressure is discharged out of the pressurizing system through the methanol water pressure relief port 8, so that the production safety is ensured; after the pressure of the methanol water is adjusted to the required pressure by the pressurizing system, the methanol water flows out of the methanol water pressurizing system through the methanol water outlet 7 so as to enter the next-stage reaction.
Example 2:
The only difference between this embodiment and embodiment 1 is that the methanol water line has a first line 9.1, a second line 9.2, a third line 9.3 and a fourth line 9.4; the methanol water inlet 6 is arranged at a port of the first pipeline 9.1, the one-way valve 1 and the switch valve 2 are sequentially arranged on the first pipeline 9.1, the booster pump 3 is arranged between the first pipeline 9.1 and the second pipeline 9.2, and the first pipeline 9.1 and the second pipeline 9.2 are communicated; the pressure relief valve 4 is arranged in the third pipeline 9.3, and the safety valve is arranged in the fourth pipeline 9.4; wherein the first line 9.1 has a first branch 9.11 and a second branch 9.12, wherein the first branch 9.11 is connected to the inlet of the booster pump 3, the inlet of the second line 9.2 is connected to the outlet of the booster pump 3, the outlet of the second branch 9.12 is connected to the inlet of the third line 9.3, and the outlet of the second line 9.2 and the outlet of the third line 9.3 converge at the inlet of the fourth line 9.4.
When the methanol water mixed solution works, the one-way valve 1 and the switch valve 2 are opened, methanol water mixed solution enters the methanol water pressurizing system from the methanol water inlet 6 in the first pipeline 9.1, and after passing through the one-way valve 1 and the switch valve 2 arranged on the first pipeline 9.1 through the methanol water pipeline, part of methanol water flows into the booster pump 3 through the first branch 9.11, and then flows into the second pipeline 9.2 after being pressurized by the booster pump 3; the other part of the methanol water flows into the third pipeline 9.3 through the second branch 9.12 and flows into the pressure relief valve 4 arranged on the third pipeline 9.3, the methanol water respectively flows through the booster pump 3 and the pressure relief valve 4, after flowing out of the outlets of the second pipeline 9.2 and the third pipeline 9.3, after being collected at the inlet of the fourth pipeline 9.4, the methanol water flows through the safety valve 5 arranged on the fourth pipeline 9.4, and finally flows out of the methanol water pressurizing system through the methanol water outlet 7 arranged at the port of the fourth pipeline 9.4. The pressure relief valve 4 adjusts the ratio of the unpressurized methanol water to the pressurized methanol water by the booster pump 3 to achieve the purpose of adjusting the pressure of the methanol water, specifically, adjusts the mixing amount of the unpressurized methanol water by the flow rate of the methanol water in the pressure relief valve 4.
Example 3:
This embodiment differs from embodiment 1 or 2 in that the minimum pressurizable pressure of the booster pump is 3MPa and the maximum pressure is 6MPa; the booster pump has a suction chamber and a discharge chamber, the outlet of the first branch 9.11 in the first line 9.1 being connected to the suction chamber of the booster pump and the inlet of the second line 9.2 being connected to the discharge chamber of the booster pump.
A pair of rotary gears, one of which is a driving gear and the other of which is a driven gear, are arranged in a pump body of the gear pump. When the gear pump operates, the driving gear drives the driven gear to rotate, and when the gear is meshed to be disconnected from the gear, partial vacuum is formed in the suction chamber, so that liquid is sucked; the sucked liquid fills each gear of the gears and is brought to the discharge chamber; when the gears are engaged, the liquid is squeezed out to form a high-pressure liquid, which is then discharged out of the pump through the discharge port of the pump.
In summary, compared with the traditional way of connecting and pressurizing a plurality of booster pumps, the technical scheme of the application can meet the pressure requirement of methanol water in the methanol hydrogen production device by only one gear booster pump; and through the design of the pipeline in the pressurizing system, the pressurizing flow of the methanol water is simplified while the methanol water pressure meets the requirement of the methanol hydrogen production process.
