Description

Technical Field

[0001] The present application relates to the field of new energy battery technology, and in particular to a gas-liquid separation device for a hydrogen fuel cell. Background Art

[0002] Hydrogen fuel cells are batteries that use hydrogen, a chemical element, to store energy. The basic principle is the reverse reaction of water electrolysis, where hydrogen and oxygen are supplied to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load.

[0003] At present, when hydrogen fuel cells are performing gas-liquid separation, it is inconvenient to adjust the inlet flow, resulting in poor gas-liquid separation processing effect. A Chinese patent with publication number CN218215378U discloses a gas-liquid separation device for a hydrogen fuel cell system, which solves the problem of being unable to adjust the inlet flow. However, in the gas-liquid separation device used, a layer of water film may be formed on the membrane surface when separation is performed using membrane separation technology, thereby affecting gas permeation. In addition, since there are still some tiny solid particles and organic residues in the incoming mixed gas, the separation membrane will be blocked under long-term filtration, making the membrane unusable. Therefore, a gas-liquid separation device for hydrogen fuel cells is designed to solve the above-mentioned problems. Utility Model Content

Figure 2 As shown, the separated water is discharged, and a filter screen 6 is installed in the front of the processing frame 1. The filter screen 6 is used to filter impurities. A fixing rod 7 is fixedly connected to the middle of one side of the filter screen 6, and a separation membrane 5 is fixedly connected to one side of the fixing rod 7. The separation membrane 5 is a polytetrafluoroethylene membrane, which is used to separate gas and liquid water. The filter screen 6 and the separation membrane 5 are connected by the fixing rod 7, so that the filter screen 6 and the separation membrane 5 can be driven and moved together;

[0023] The middle part of the separation membrane 5 away from the filter screen 6 is fixedly connected to the mounting rod 8, the mounting rod 8 is fixedly connected to the gear plate 9 away from the separation membrane 5, the front part of the gear plate 9 engages with the half gear 10, the gear plate 9 is fixedly connected to the side away from the separation membrane 5 with a spring 11, and the spring 11 is fixedly connected to the inner wall of the processing frame 1 on the side away from the gear plate 9.

[0024] The half gear 10 drives the gear plate 9 to move to the side away from the intake pipe 2, and squeezes the spring 11 to shrink it. At the same time, the gear plate 9 drives the mounting rod 8 to move, and the mounting rod 8 drives the separation membrane 5 to move. The separation membrane 5 drives the filter screen 6 to move through the fixing rod 7. When the half gear 10 rotates and no longer meshes with the gear plate 9, the spring 11 recovers and drives the gear plate 9 to recover, so that the gear plate 9 drives the separation membrane 5 and the filter screen 6 on the side of the mounting rod 8 to recover. Due to the thrust of the spring 11, and the instantaneous action, the separation membrane 5 and the filter screen 6 move quickly, and shake off the impurities adhering to the filter screen 6 and the separation membrane 5 to keep the filter screen 6 and the separation membrane 5 in normal use.

The slide rod 91 is used to limit the gear plate 9 so that the gear plate 9 can only move horizontally, thereby ensuring the stable movement of the gear plate 9.

[0027] By adopting the above technical solution, the middle part of the upper end of the half gear 10 is fixedly connected to the support rod 14, and the upper end of the support rod 14 is rotatably connected to the inner wall of the processing frame 1. The support rod 14 is provided to maintain the supporting effect on the half gear 10, so that the half gear 10 remains stable and avoids the misalignment of the half gear 10 and the inability to mesh with the gear plate 9 again.

[0029] By adopting the above technical solution, the mesh plate 16 is fixedly connected in the collection frame 15. The mesh plate 16 can filter out impurities in the water to prevent them from entering the outlet pipe 4. A switch door is installed in the front of the collection frame 15 to open the collection frame 15 and clean out the impurities on the mesh plate 16.
