Description

Technical Field

[0001] This utility model belongs to the field of gas-water separation technology, and in particular relates to a novel gas-water separation device for hydrogen fuel cells. Background Technology

[0002] Hydrogen fuel cells can convert the chemical energy of hydrogen into electrical energy to generate electricity. In order to recover the energy of the cathode gas, the cathode gas is usually delivered to the turbine. However, the cathode gas needs to be processed by a gas-liquid separator before being delivered to the turbine. The gas-liquid separator separates the liquid water and most of the water vapor in the cathode exhaust gas in advance, providing the turbine with dry and clean intake gas. Existing gas-liquid separation devices include a separation box, which contains a cyclone separation chamber and a baffle separation chamber. The bottom of the cyclone separation chamber is connected to the baffle separation chamber. A baffle assembly is provided inside the baffle separation chamber. The separation box is provided with an air inlet and an air outlet. The air inlet is connected to the cyclone separation chamber and is eccentrically positioned. The air outlet is connected to the baffle separation chamber. This existing gas-water separator, because it has internal baffles to separate gas and water, requires stopping the gas-water separation after a period of operation before the baffles can be replaced and the collected water discharged, which affects the continuity of gas-water separation and reduces its efficiency.

As shown in Figure 1, a novel hydrogen fuel cell gas-water separation device includes a first separation box 1, a second separation box assembly 3, and a water collection tank assembly 4. A cyclone separator 11 is fixedly installed inside the first separation box 1. The air inlet of the cyclone separator 11 extends to the outside of the first separation box 1. The air outlet and water outlet of the cyclone separator 11 are both located inside the first separation box 1. Air valves 2 are installed at the air outlets that are opened side by side on the upper side of one side of the first separation box 1. The two air valves 2 are respectively connected to the two second separation box assemblies 3.

[0018] In this implementation plan, in conjunction with the appendix Figure 2 As shown, the second separation box assembly 3 includes a box body 31. A support frame 32 is integrally provided on the lower side of the inside of the box body 31. A base plate 33 is provided on the upper part of the support frame 32. A top frame 35 is also provided inside the box body 31. An air-water filter cartridge 34 is installed between the top frame 35 and the base plate 33. A box cover 36 is sealed and detachably fixedly installed at the upper end of the box body 31. Mounting seats 37 are integrally provided at the four corners of the box cover 36. A U-shaped frame 38 is integrally provided at the lower part of the box cover 36. The U-shaped frame 38 is located on the upper part of the top frame 35. An exhaust valve 39 is fixedly installed at the air outlet opened at the upper part of the box cover 36. Water is intercepted by the air-water filter cartridge 34 and enters the box body 31 for collection. Gas passes through the air-water filter cartridge 34 and is discharged to the next process through the exhaust valve 39. By opening and closing the air valve 2, continuous separation of air and water can be achieved.

[0019] In this implementation plan, in conjunction with the appendix Figure 3As shown, the water collection tank assembly 4 includes a water collection tank 41. A drain valve 43 is fixedly installed at the lower outlet of the water collection tank 41. One-way inlet valves 42 are fixedly installed at the water inlets sequentially opened at the upper part of the water collection tank 41. A pressure balancing valve 44 is fixedly installed at the upper exhaust port of the water collection tank 41. Water in the first separation tank 1 and water in the tank body 31 enter the water collection tank 41 through the one-way inlet valves 42 for collection. After all the one-way inlet valves 42 are closed, the user opens the drain valves 43 to discharge the water to the next process, so as to avoid the drainage process affecting the continuous separation of air and water.

[0023] In this embodiment, specifically, the lower end of the air-water filter cartridge 34 is inserted and fixed in an integrated annular seat on the upper part of the base plate 33. A rubber sealing ring is provided inside the annular seat. The rubber sealing ring serves to fix the lower end of the air-water filter cartridge 34 and to seal it, preventing unfiltered air from passing through the gap between the annular seat and the air-water filter cartridge 34. When the top plate 35 is removed for inspection and maintenance, the air-water filter cartridge 34 can be pulled out from the base plate 33 and the top frame 35, which is convenient for disassembly and maintenance.

[0024] In this embodiment, specifically, the mounting base 37 and the housing 31 are detachably installed.

[0025] In this embodiment, specifically, the plurality of one-way water inlet valves 42 are respectively connected to the water outlet pipes opened at the bottom of the first separation box 1 and the water outlet pipes opened at the bottom of the box body 31.

[0027] Working principle

[0028] In this invention, the cathode gas pipeline of the hydrogen fuel cell is connected to the air inlet of the cyclone separator 11. The cathode gas enters the cyclone separator 11 for primary gas-water separation. Water enters the first separation chamber 1 from the lower drain outlet of the cyclone separator 11. The gas after primary separation enters the first separation chamber 1 from the air outlet of the cyclone separator 11. One gas valve 2 is open and the other gas valve 2 is closed. The water collection tank assembly 4 opened by the gas valve 2 performs secondary gas-water separation.
