As shown in fig. 1, the present embodiment discloses a water-gas separation device of a hydrogen fuel cell system, which includes a device body 1, a filtering water absorbing member 2, an air inlet pipe 3, and a liquid level meter 4.
The device body 1 is provided with an accommodating cavity, the device body 1 is cylindrical, and the accommodating cavity is a cylindrical cavity. The top of the device body 1 is provided with an exhaust port 11, the bottom is provided with a water outlet 12, the water outlet 12 is provided with a control valve 121, and the control valve 121 is an electric control valve.
The filtering and water absorbing part 2 is arranged in the containing cavity, is positioned in the middle position of the containing cavity, and is divided into an exhaust cavity 13 above and a drainage cavity 14 below by the containing cavity. The inner wall of the accommodating cavity is coated with an antirust coating, so that the inner wall of the device body 1 can be prevented from rusting. The filtering and water absorbing piece 2 is a water absorbing sponge, two fixing pieces are arranged at the interval of the middle position of the accommodating cavity inner wall, and the filtering and water absorbing piece 2 is clamped between the two fixing pieces so as to fix the filtering and water absorbing piece 2 in the accommodating cavity.
The exhaust cavity 13 is used for temporarily storing gas and exhausting the gas through the exhaust port 11; the drain chamber 14 serves to hold water and to drain through the drain port 12. The lower end surface of the exhaust port 11 is recessed towards the exhaust cavity 13, so that the plane of one end of the exhaust port 11 connected with the exhaust cavity 13 is slightly lower than the exhaust cavity 13, and the resistance of gas exhaust can be increased. The top end wall of the device body 1 is arranged in a protruding mode upwards and is in a spherical shape, the exhaust port 11 is arranged in the center of the top end wall, but the center of the top end wall is lower than the surrounding height of the top end wall, and therefore the plane where one end of the exhaust port 11 connected with the exhaust cavity 13 is located is slightly lower than the exhaust cavity 13. The bottom end wall of the device body 1 is arranged in a downward convex manner, is spherical, and has the lowest central position, and the water outlet 12 is arranged in the middle of the bottom end wall. When the water-gas separating device is not used, accumulated water in the drainage cavity 14 can be completely drained, and the accumulated water cannot remain in the drainage cavity 14 to corrode the device body 1.
The air inlet pipe 3 is spiral, and the axis of the spiral line of the air inlet pipe is arranged along the vertical direction. The inlet end of the air inlet pipe 3 is connected to the air inlet of the device body 1, and the outlet end extends into the drainage cavity 14.

Along with the gas mixture enters into air intake duct 3 from air inlet 15 of device body 1, when flowing through spiral helicine air intake duct 3, most steam forms the water droplet on attaching to the inner wall of air intake duct 3 under the effect of centrifugal force, the water droplet flows into in the drainage chamber 14 under the effect of gravity, the gas mixture that flows through air intake duct 3 enters into behind the drainage chamber 14, come up under the effect of gravity, when permeating filtration water absorption piece 2, filtration water absorption piece 2 absorbs remaining most water in the gas mixture, then enter into exhaust chamber 13, discharge from gas vent 11. When the amount of water absorbed by the filtering water absorbing member 2 is too large, the water on the filtering water absorbing member 2 falls into the water discharge chamber 14. The water separated from the mixture accumulates in the drainage chamber 14, the level of the liquid in the drainage chamber 14 rises gradually and the reading of the gauge 4 starts to rise. When the liquid level reaches a certain limit value (lower than the level of the outlet end of the air inlet pipe 3 at the water discharge cavity 14), the control valve 121 is opened, and the water discharge port 12 automatically discharges water.
In the drainage process, the liquid level state is monitored in real time, when the liquid level in the drainage cavity 14 is lower than the lowest liquid level allowance, the control valve 121 is closed in a water seal state, and the mixed gas is prevented from leaking out through the drainage port 12 under the action of high pressure due to too low liquid level in an active control mode.
Combine gravity separation and centrifugal separation mode, set up spiral helicine admission line 3 in the big air inlet 15 department of device body 1, higher air pressure when make full use of admits air directly gets into the centrifuging tube, realizes better moisture separation under great centrifugal force effect, and the separation effect is obvious.
