Description

Technical Field

[0001] This application relates to the technical field of pipeline vibration elimination for hydrogen production by electrolyzing water, and particularly to a pipeline vibration elimination system for the gas-liquid separation system of hydrogen production by electrolyzing water. Background Art

[0002] Hydrogen production by electrolyzing water is an important way to produce clean energy, and its core technology is to electrolyze water into hydrogen and oxygen. In the gas-liquid separation system of hydrogen production by electrolyzing water, the electrolytic water hydrogen production system is used for electrolytic reaction, and the gas-liquid separation system is used to separate the mixed gas-liquid generated by the electrolytic reaction. In the gas-liquid mixing pipeline between the electrolytic water hydrogen production system and the gas-liquid separation system, pipeline vibration is a common phenomenon. The reasons for pipeline vibration include: fluctuations in fluid flow rate and pressure, unstable factors during equipment operation, unreasonable pipeline design and installation, etc. Pipeline vibration will cause pipeline wear and fatigue, affect the equipment life, and may cause pipeline rupture and gas leakage in extreme cases. Therefore, it is necessary to study the pipeline vibration elimination of the gas-liquid separation system for hydrogen production by electrolyzing water.

[0003] In the prior art, Chinese Patent CN117959900A discloses a gas-liquid separation tower and a gas-liquid separation method for hydrogen production by electrolyzing water. The gas-liquid separation tower includes an electrolyte cooling section, a gas-liquid separation section, a gas washing section, a first droplet capture section, a gas drying section, a second droplet capture section, and a gas discharge section connected from bottom to top. The electrolyte cooling section is provided with a first cooling flow path and an electrolyte flow path for heat exchange with each other. The electrolyte flow path communicates with the gas-liquid separation section. The gas-liquid separation section is provided with a gas-liquid mixture inlet. The gas washing section communicates the gas-liquid separation section with the first droplet capture section. The gas drying section is provided with a drying flow path and a second cooling flow path for heat exchange with each other. The drying flow path communicates the first droplet capture section and the second droplet capture section. The second droplet capture section communicates with the gas discharge section. The gas discharge section is provided with a gas discharge port.

[0004] However, the above prior art does not study the pipeline vibration elimination of the gas-liquid separation system for hydrogen production by electrolyzing water. Pipeline vibration during hydrogen production by electrolyzing water and gas-liquid separation will reduce the system stability; at the same time, production interruption caused by pipeline vibration will reduce the system production efficiency, and instability caused by pipeline vibration will reduce the separation effect. Summary of the Invention

[0005] This application provides a pipeline vibration elimination system for the gas-liquid separation system of hydrogen production by electrolyzing water to solve the problems in the prior art that pipeline vibration during hydrogen production by electrolyzing water and gas-liquid separation will reduce the system stability, production interruption caused by pipeline vibration will reduce the system production efficiency, and instability caused by pipeline vibration will reduce the separation effect.

[0006] On the one hand, the present application provides a pipeline vibration elimination system for an electrolytic water hydrogen production gas-liquid separation system, including: a pressure controller, a solenoid valve, a cylinder, a hydraulic cylinder, a damping adjustment device, and a driving gas source.

[0008] The pressure controller is used to monitor whether the gas-liquid mixing pipeline between the electrolytic water hydrogen production system and the gas-liquid separation system vibrates.

[0009] When the pressure controller monitors that the gas-liquid mixing pipeline vibrates, the solenoid valve is used to open the intake valve of the cylinder; the driving gas source is used to introduce pressurized gas into the cylinder; the cylinder is used to push the hydraulic cylinder under the action of the pressurized gas; the hydraulic cylinder is used to drive the damping adjustment device to eliminate pipeline vibration under the push of the cylinder.

[0011] In a possible implementation, the driving gas source is also mechanically connected to the solenoid valve.

[0012] When the pressure controller monitors that the gas-liquid mixing pipeline vibrates, the solenoid valve is also used to open the intake valve of the cylinder driven by the pressurized gas of the driving gas source.

[0013] When the pressure controller monitors that the gas-liquid mixing pipeline does not vibrate, the solenoid valve is also used to close the intake valve of the cylinder driven by the pressurized gas of the driving gas source.

[0014] In a possible implementation, the pressure controller adopts a mechanical pressure controller or an electronic pressure controller.

[0015] In a possible implementation, the damping adjustment device adopts a hydraulic shock absorber or a spring shock absorber.

[0016] In a possible implementation, the pressure controller and the solenoid valve adopt an interlock control mechanism.

[0017] In a possible implementation, the pressure controller and the driving gas source also adopt an interlock control mechanism.

[0018] The pipeline vibration elimination system for the hydrogen and liquid separation system in electrolytic water hydrogen production in this application has the following advantages: By combining a pressure controller, a solenoid valve, a cylinder, a hydraulic cylinder, a damping adjustment device, and a driving gas source to eliminate the pipeline vibration in electrolytic water hydrogen production, it reduces pipeline wear and fatigue, lowers the failure rate, and thus improves the stability of the hydrogen and liquid separation system in electrolytic water hydrogen production; the improvement of stability means a reduction in production interruption, thereby improving the production efficiency of electrolytic water hydrogen production; the improvement of stability also means that the mixing degree of the produced hydrogen, oxygen, and excess water is not high, thus improving the gas-liquid separation effect. In addition, pipeline vibration is often accompanied by noise, and eliminating pipeline vibration can also reduce or eliminate noise pollution and reduce the impact on the environment; an efficient and stable hydrogen and liquid separation system in electrolytic water hydrogen production can meet higher standard energy demands and promote the upgrading of industries related to electrolytic water hydrogen production technology.

[0019] The proposed driving gas source is also mechanically connected to the solenoid valve, and the opening and closing of the solenoid valve are driven by the pressurized gas of the driving gas source, improving the control efficiency and control accuracy of the solenoid valve.

[0020] The proposed pressure controller and the solenoid valve adopt an interlocking control mechanism, and the pressure controller also adopts an interlocking control mechanism with the driving gas source. Through the interlocking control mechanism, it ensures that the pressure controller, the solenoid valve, and the driving gas source work together in the correct sequence, avoiding misoperation and failures, and improving the working stability of the system.
