Gas-liquid separator
A gas-liquid separator includes: a housing including a gas inlet, a gas outlet, and a water storage section at a lower side of the gas inlet and the gas outlet; a collision wall provided inside the housing to collide with a gas that contains water introduced from the gas inlet to separate the water from the gas by adhering the water thereto while changing a flow direction of the gas; and a downflow wall provided inside the housing to introduce the water falling from the collision wall into the water storage section and change the flow direction of the gas.
1. A gas-liquid separator comprising:
a housing including a gas inlet, a gas outlet, a gas-liquid separating section, and a water storage section at a lower side of the gas inlet and the gas outlet, the gas-liquid separating section including a bulging wall inside which a separation space is formed, the gas inlet formed at an upper end of the bulging wall;
a plurality of collision walls extending from an inner wall of the bulging wall to collide with a gas that contains water introduced from the gas inlet to separate the water from the gas by adhering the water thereto while changing a flow direction of the gas, the plurality of collision walls includes a first collision wall on which the gas from the gas inlet collides, the first collision wall extending from the inner wall along a line that intersects with an adjacent collision wall of the plurality of collision walls to create a swirl flow in the separation space in which separation of the gas that contains water is performed; and
a downflow wall provided inside the housing to introduce the water falling from the collision wall into the water storage section and change the flow direction of the gas.
2. The gas-liquid separator according to claim 1 ,
wherein the downflow wall is spaced apart from the plurality of collision walls and is disposed vertically below the collision walls.
3. The gas-liquid separator according to claim 1 ,
wherein a position of the gas inlet and a supply direction of the gas by the gas inlet are set so as to supply the gas obliquely from above the plurality of collision walls.
4. The gas-liquid separator according to claim 1 ,
wherein a lower end of the gas inlet is set to a position higher than an upper end of the plurality of collision walls.
5. The gas-liquid separator according to claim 1 ,
wherein the plurality of collision walls guides the swirl flow downward while causing the swirl flow to swirl.
6. The gas-liquid separator according to claim 5 , wherein the swirl flow is created by sequentially colliding with the plurality of collision walls and swirls in the separation space.
7. The gas-liquid separator according to claim 1 ,
wherein the plurality of collision walls has a lower end oblique to a vertical direction of the housing, and the lower end is disposed above the downflow wall.
8. The gas-liquid separator according to claim 1 ,
wherein the plurality of collision walls are angled to change the flow direction of the gas via the gas sequentially colliding with the plurality of the collision walls.
9. The gas-liquid separator according to claim 1 ,
wherein the inner wall is circular in plan view.
10. The gas-liquid separator according to claim 1 ,
each of the plurality of collision walls extends from the inner wall along a respective line that intersects another of the plurality of collision walls.
11. The gas-liquid separator according to claim 1 ,
the gas inlet and the plurality of collision walls are arranged to create the swirl flow in a tangential direction and a downward direction with reference to the inner wall.
