Description

Technical Field

[0001] This utility model relates to the field of hydrogen mixing devices, and in particular to a high-purity hydrogen mixing device. Background Technology

[0002] Hydrogen is a gas that is highly flammable at room temperature and pressure and poorly soluble in water. It exhibits reducing properties when reacting with highly electronegative nonmetals and oxidizing properties when reacting with active metals, making it widely used in chemical preparation and electronic product manufacturing. Currently, common related processes often require hydrogen to be thoroughly mixed with other gaseous or liquid raw materials before being sent to the relevant processing facilities. If hydrogen is not adequately mixed with other substances during this process, it will severely affect the processing quality. However, existing mixing and processing equipment has poor mixing efficiency, is inconvenient to install and assemble, and is difficult to maintain, failing to meet current usage requirements. Utility Model Content

[0005] A high-purity hydrogen mixing device includes a shell, a dispersion tube, and a mixing capillary tube. The shell is cylindrical with an internal cavity. One end of the shell has an inlet, and the other end has an outlet. An inlet pipe is located inside the shell, with one end fixedly connected to the shell and communicating with the inlet. A sealing port is fixedly connected to the shell on the side of the inlet pipe away from the inlet. The dispersion tubes are located on both sides of the inlet pipe, with a diverter pipe on the side of the dispersion tube closest to the sealing port. A diverter pipe is fixedly located on the outer side of the inlet pipe. The interface is fixedly connected to the splitter pipe. Multiple dispersion plates are fixed inside the dispersion pipe.

A flow guide interface is fixed on the side of the mixing fine tube away from the flow guide interface. One side of the flow guide interface has a pipe that communicates with the outlet interface for outputting the mixed gas to the outside.

[0006] As an improvement, the outer shell is made of hard alloy, the vent port has threads on the side away from the outer shell, and an end cap is fitted and fixed on the outside of the vent port.

[0020] The outer casing 1 is made of hard alloy. The air outlet 15 has threads on the side away from the outer casing 1. An end cap 3 is fixedly fitted onto the outer side of the air outlet 15. The end cap 3 is sealed to the outer casing 1 by threads. The end cap 3 is used to facilitate the inspection and maintenance of the internal structure of the outer casing 1. The diameter of the dispersion tube 8 is larger than the diameter of the air inlet tube 5. The axis of the dispersion tube 8 is parallel to the axis of the air inlet tube 5. The dispersion plate includes a dispersion plate A16 and a dispersion plate B17. The dispersion plate A16 is conical in shape, with its tip facing the diverter tube 7. The dispersion plate A16 has multiple air holes in the middle. The diameter of the round holes on the side closer to the diverter tube 7 is smaller than the diameter on the side farther from the diverter tube 7. The dispersion plate A16 has combing holes near the side wall of the dispersion tube 8. The diameter of the combing holes is larger than the diameter of the round holes.

The center of the dispersion plate B17 has a combing hole, and circular holes are distributed around the combing hole. The circular holes of the dispersion plate A16 and the dispersion plate B17 are staggered, so that the gas will be dispersed and mixed sequentially after passing through the circular holes.

[0021] Eight mixing capillary tubes 11 are provided in total, arranged in groups of four. An inner fixing ring 18 is fitted and fixed inside the mixing capillary tube 11. A flow-encircling ring 20 is provided inside the inner fixing ring 18. The flow-encircling ring 20 is shaped like a frustum cone and has a through hole on its inner side. The smaller diameter opening of the flow-encircling ring 20 faces the reversing port 10. A flow-deflecting plate 19 is arranged around the outer side of the flow-encircling ring 20.

One end of the secondary mixing pipe 13 has a pipe that communicates with the air outlet interface 15. The secondary mixing pipe 13 is used for gas splitting and collision, slowing down the gas flow speed and mixing. The mixing capillary tube 11 includes multiple baffles 19 and a flow ring 20. The baffles 19 are arranged in groups of three, surrounding the outside of the flow ring 20, and the baffles 19 in each group are staggered.

[0022] When in use, the air inlet 2 is aligned with the gas delivery pipe and sealed, and the air outlet 15 is sealed with the corresponding air outlet pipe or processing device. When multiple gases enter the air inlet pipe 5 through the air inlet 2, they are guided into the dispersion pipe 8 through the diverter pipe 7. At this time, the dispersion plate A16 and dispersion plate B17 in the dispersion pipe 8 slow down the gas entry speed, stabilize the gas mixing volume, and disperse and mix multiple gases. Then, the gas enters the mixing tube 11 through the reversing port 10. At this time, the mixed gas is cut, dispersed, and squeezed by the baffle plate 19 and the flow ring 20, further mixing the gas. Then, the mixed gas is sent into the secondary mixing tube 13 through the guide port 12. At this time, the secondary mixing tube 13 disperses the mixed gas multiple times and counter-flushes it to achieve uniform mixing of multiple gases, and then sends it out from the air outlet 15. Liquid raw materials can be mixed and prepared together during mixing.
