[0002] The hydrogen gas leaving the stack of a hydrogen fuel cell contains a large amount of liquid water. Gas-liquid separation is required before it re-enters the stack to prevent the liquid water from flooding the stack membrane electrodes, which in turn causes the fuel cell to malfunction and shut down.

[0003] The existing steam-water separator has relatively low separation efficiency due to the limitations of volume and flow resistance. Utility Model Content

[0007] The circles in the spiral inner cavity are arranged at the same height, and the spiral radius of each circle gradually decreases from the outside to the inside. The air inlet is connected to the outermost circle of the spiral inner cavity, and the air outlet and the liquid discharge are respectively connected to the innermost circle of the spiral inner cavity.

[0008] Preferably, a spiral side wall for cooperating to form the spiral inner cavity is provided in the main body, and the inner surface of the spiral side wall is inclined inward from bottom to top.

[0015] Preferably, the inner diameter of the drainage portion gradually decreases along the drainage direction.

[0016] Preferably, the air outlet of the air outlet portion and the liquid discharge port of the liquid discharge portion are vertically aligned in an up-down direction.

[0017] Due to the application of the above technical solution, the present invention has the following advantages compared with the existing technology: the disc-type steam-water separator of the present invention has a small overall flow resistance by arranging spiral inner cavities with the same height in each circle in the cylindrical main body, and the steam-water separation path is extended in the same space, thereby improving the steam-water separation efficiency; the spiral radius of the spiral inner cavity gradually decreases from the outside to the inside, so that the centrifugal force exerted on the liquid water during the separation process gradually increases, which can further improve the steam-water separation efficiency.

[0030] See also Figure 1-4 As shown, this embodiment provides a disc-type steam-water separator, including a cylindrical main body 1 with a spiral inner cavity 2, an air inlet portion 3 provided on the outer circumferential surface 11 of the main body 1, an air outlet portion 4 provided above the upper end surface 12 of the main body 1, and a liquid discharge portion 5 provided below the lower end surface 13 of the main body 1, wherein the air inlet portion 3, the air outlet portion 4 and the liquid discharge portion 5 are respectively connected to the main body 1.

[0031] The spiral inner cavity 2 is composed of multiple spiral channels connected in sequence, each of which is arranged at the same height, and the spiral radius of each spiral channel gradually decreases from the outside to the inside. The air inlet 3 is connected to the outermost spiral channel of the spiral inner cavity 2, and the air intake direction of the air inlet 3 is parallel to the tangent direction of the air inlet of the spiral inner cavity 2. In other words, the air inlet 31 is parallel to the tangent of the air inlet of the outermost spiral channel, to minimize the loss of kinetic energy during air intake. In this embodiment, the inner diameter of the air inlet 3 gradually increases along the air intake direction until its shape matches the cross-section of the spiral channel.

[0032] See also Figure 2 As shown, the upper end surface 12 and the lower end surface 13 of the main body 1 are parallel to each other and parallel to the horizontal plane. The gas outlet 4 and the liquid discharge portion 5 are respectively connected to the innermost circle of the spiral inner cavity 2, and are used to guide the separated gas and liquid respectively transferred to the innermost circle.

[0033] In this embodiment, the outlet direction of the outlet portion 4 is perpendicular to the upper end surface 12 of the main body 1 , and the inner diameter of the outlet portion 4 gradually decreases along the outlet direction, so as to guide the separated gas upward and leave the spiral inner cavity 2 .

[0034] In this embodiment, the discharge direction of the discharge portion 5 is perpendicular to the lower end surface 13 of the main body 1 , and the inner diameter of the discharge portion 5 gradually decreases along the discharge direction, so as to guide the separated liquid downward to leave the spiral inner cavity 2 .

[0035] In this embodiment, the air outlet portion 4 and the liquid discharge portion 5 are both conical in shape, and the air outlet 41 of the air outlet portion 4 and the liquid discharge port 51 of the liquid discharge portion 5 are vertically aligned in the up-down direction.

[0036] See also Figure 3 As shown, the main body 1 is provided with a spiral sidewall 6 that cooperates with the upper end surface 12 and the lower end surface 13 to form the spiral inner cavity 2. The inner surface of the spiral sidewall 6 is inclined inward from bottom to top. This arrangement effectively reduces the tendency of droplets to flow upward during high-speed transport, allowing the disc-type steam-water separator to effectively separate steam and water over a wide range of inlet flow rates, further improving the steam-water separation effect. In this embodiment, the outer surface of the spiral sidewall 6 is parallel to the vertical direction.

[0037] See also Figure 4As shown, the width of each circle in the spiral inner cavity 2 is the same, the cross-sectional area of ​​the entire flow channel is consistent, and there are no components such as baffles and fillers that increase flow resistance, thereby further reducing the overall flow resistance.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
