Description

Technical Field

[0001] This utility model belongs to the technical field of hydrogen mixing equipment, specifically a hydrogen mixing device with internal wall rotary spray washing. Background Technology

[0002] Hydrogen blending technology for natural gas may be an effective way to address the challenges faced by natural gas and renewable energy. This technology utilizes renewable energy sources that cannot be absorbed by the power grid, such as water electrolysis to produce hydrogen. This hydrogen is then injected into natural gas pipelines to mix with natural gas, forming hydrogen-blended natural gas. This blended natural gas is then transported to end-user applications, creating a systematic application of "hydrogen production, blending, transportation, and utilization." This technology not only improves the utilization rate of renewable energy, helping to address my country's problems of wind, solar, and hydropower curtailment, but also allows for the partial substitution of natural gas with hydrogen, reducing my country's dependence on imported natural gas. Furthermore, hydrogen-blended natural gas can reduce pollutants generated during end-user combustion, helping to solve urban acid rain problems. Therefore, the application of hydrogen blending technology is one of the important directions for the future development of the natural gas industry.

[0003] The principle of natural gas blending with hydrogen is to mix hydrogen and natural gas in a certain proportion to form a new alternative gaseous fuel. This blend combines the advantages of hydrogen (fast combustion speed, wide ignition limit) and natural gas (high volumetric calorific value), which can improve the combustion rate and engine performance of the natural gas mixture while reducing emissions.

[0004] Blending natural gas with hydrogen requires a hydrogen blending device, which includes a mixing tank where natural gas and hydrogen are mixed. Existing hydrogen blending devices can meet the requirements for blending natural gas with hydrogen, but they still have the following problems: After prolonged use, the inner wall of the mixing tank needs to be cleaned to prevent impurities from affecting the gas reaction. However, the surface of the mixing tank is smooth and irregular, making cleaning time-consuming and labor-intensive, which is not conducive to the cleaning operation. Utility Model Content

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0032] like Figure 1-3As shown, the hydrogen mixing device for internal wall rotary spray cleaning in this embodiment includes a hydrogen mixing tank 1. An inlet pipe 3 and an outlet pipe 4 are connected to the side wall of the hydrogen mixing tank 1. By providing the inlet pipe 3, the processed gas can enter the hydrogen mixing tank 1, mix, and then be discharged through the outlet pipe 4. The hydrogen mixing tank 1 in this embodiment is equipped with an internal wall cleaning device. Specifically, the internal wall cleaning device includes a cleaning support, a rotation drive mechanism for driving the cleaning support to rotate, and a liquid supply device for providing clear liquid to the cleaning support.

[0033] like Figure 2-3 As shown, in this embodiment, the cleaning support includes a ring pipe 17 and a transition cylinder 20 located at the center of the ring pipe. A connecting pipe 16 connects the ring pipe 17 and the transition cylinder 20. A nozzle 18 is installed on the ring pipe 17. Specifically, at least two connecting pipes 16 are evenly distributed in a ring; in this embodiment, four connecting pipes 16 are evenly distributed in a ring. By evenly distributing multiple connecting pipes 16 in a ring, the cleaning fluid can enter the ring pipe 17 more evenly, and the spray volume of each nozzle 18 can be more uniform. Specifically, the nozzles 18 are evenly distributed in a ring on the ring pipe 17; in this embodiment, eight nozzles 18 are evenly distributed in a ring on the ring pipe 17. By evenly distributing the nozzles 18 in a ring, the cleaning operation of the nozzles 18 on the inner wall of different areas of the hydrogen mixing tank 1 can be more uniform.

[0034] like Figure 2-3 As shown, in this embodiment, the rotation drive mechanism includes a drive shaft 15 connected to the adapter cylinder 20 and a power device driven by the drive shaft 15.

In this embodiment, the output shaft of the motor 2 is connected to the drive shaft 15, and the motor 2 can drive the drive shaft 15 to rotate, thereby driving the entire cleaning bracket to rotate, achieving the technical purpose of rotating and spraying the inner wall of the hydrogen mixing tank 1.

[0035] like Figure 3 As shown, in this embodiment, the liquid supply device includes a liquid supply pipe 14 that rotatably engages with the adapter cylinder 20, and the liquid supply pipe 14 is coaxially arranged with the drive shaft 15. In a preferred embodiment, the liquid supply pipe 14 is rotatably connected to the lower surface of the adapter cylinder 20, and a waterproof bearing 19 is provided between the liquid supply pipe 14 and the adapter cylinder 20. The inner ring surface of the waterproof bearing 19 is interference-fitted with the outer surface of the liquid supply pipe 14 and rotates synchronously, which not only achieves the technical purpose of allowing the adapter cylinder 20 to rotate relative to the liquid supply pipe 14, but also prevents the cleaning fluid in the adapter cylinder 20 from leaking.

[0036] like Figure 3As shown, in this embodiment, the liquid supply device includes a liquid supply tank 9 and a water pump 13 installed on the liquid supply tank 9. The liquid supply pipe 14 is connected to the outlet of the water pump 13, and the inlet of the water pump 13 is connected to an inlet pipe 10 that extends into the liquid supply tank 9. An inlet funnel 11 is installed on the upper surface of the liquid supply tank 9, and a stopper plate 12 is provided inside the inlet funnel 11. By setting the stopper plate 12, the inlet funnel 11 can be opened to inject new cleaning liquid into the liquid supply tank 9.

[0037] like Figure 2-3 As shown, in this embodiment, the drive shaft 15 is coaxial with the hydrogen mixing tank 1, and the annular pipe 17 is a circular annular pipe, with the plane containing the center line of the annular pipe 17 perpendicular to the drive shaft 15. Of course, in some other embodiments, the annular pipe 17 can also be an elliptical annular pipe, with the angle between the plane containing the center line of the annular pipe 17 and the drive shaft 15... for:

[0038]

[0039] in: and These are the lengths of the major and minor axes of the ellipse formed by the center lines inside the elliptical ring pipe.

[0040] Thus, the drive ring tube 17 rotates. Since the elliptical ring tube is inclined relative to the drive shaft 15, it can spray and wash the inner wall of the hydrogen mixing tank 1 at different positions along the axial direction during the rotation of the elliptical ring tube, which can effectively increase the spraying area of ​​the inner wall.

[0041] like Figure 1-2 As shown, the hydrogen mixing device for rotating spray cleaning of the inner wall in this embodiment also includes a base plate 6, and the hydrogen mixing tank 1 and the liquid supply tank 9 are both installed on the base plate 6. The bottom of the hydrogen mixing tank 1 in this embodiment is provided with a support leg 5, which creates a bottom space between the bottom surface of the hydrogen mixing tank 1 and the base plate 6. A drain cylinder 7 for discharging cleaning liquid is provided on the bottom surface of the hydrogen mixing tank 1, and a threaded plug rod 8 is installed inside the drain cylinder 7.

[0042] The hydrogen mixing device for internal wall rotary spraying in this embodiment is an internal wall cleaning device that includes a cleaning support, a rotation drive mechanism, and a liquid supply device inside the hydrogen mixing tank 1. The liquid supply device injects cleaning liquid into the transfer cylinder 20 through the liquid supply pipe 14. The cleaning liquid in the transfer cylinder 20 is then injected into the ring pipe 17 through the connecting pipe 17, and finally sprayed out through the nozzle 18 to clean the inner wall of the hydrogen mixing tank 1. During the cleaning process, the drive shaft 15 is driven to rotate by the power device, and the entire cleaning support is driven to rotate under the action of the drive shaft 15, thereby achieving the technical purpose of rotary spraying cleaning of the inner wall of the hydrogen mixing tank 1 and meeting the requirements for cleaning the inner wall of the hydrogen mixing tank.
