Gas-liquid separator
The present invention provides a gas-liquid separator with enhanced performance and easy operation, enabling to perform gas-liquid separation such as advanced defoaming or degassing, and facilitating easy cleaning with CIP (Cleaning In Place) and COP (Cleaning Out Place) ability that meets sanitary specifications. This gas-liquid separator for gas-liquid separation performed by centrifugal force of an impeller mounted on a shaft which rotates in a casing comprises: a discharge impeller part providing discharge force to the passing fluid formed on an axial end of the impeller; a discharge outlet of the casing disposed in a position opposite the discharge impeller part; the other axial end of the impeller being formed to slide on the inner wall of the casing; an exhaust outlet of the casing disposed in a position opposite the sliding impeller part; vacuum means connected to the exhaust outlet; and a suction inlet of the casing disposed in a position between the discharge outlet and the exhaust outlet.
1. A gas-liquid separator for gas-liquid separation performed by centrifugal force of an impeller mounted on a shaft which rotates in a casing comprising:
a discharge impeller part providing discharge force to the passing fluid formed on an axial end of the impeller; a discharge outlet of the casing disposed in a position opposite the discharge impeller part;
the other axial end of the impeller being positioned with clearance from the inner wall of the casing so as to slide on the inner wall of the casing;
an exhaust outlet of the casing disposed in a position opposite the sliding impeller part; vacuum means connected to the exhaust outlet; and
a suction inlet of the casing disposed in a position between the discharge outlet and the exhaust outlet.
2. The gas-liquid separator according to claim 1 , wherein a cleaning fluid inlet is provided near the shaft sealing of the casing where the rotating shaft penetrates.
3. The gas-liquid separator according to claim 1 , wherein the inlet to the casing is formed in a flow path that winds up inside the casing.
4. The gas-liquid separator according to claim 2 , wherein the inlet to the casing is formed in a flow path that winds up inside the casing.
5. The gas-liquid separator according to claim 1 , wherein the impeller is provided with a baffle member which prevents the direct penetration of liquid near the rotating shaft to the exhaust outlet.
6. The gas-liquid separator according to claim 2 , wherein the impeller is provided with a baffle member which prevents the direct penetration of liquid near the rotating shaft to the exhaust outlet.
7. The gas-liquid separator according to claim 1 , wherein the impeller is provided with at least one cylindrical member coaxially attached to the impeller.
8. The gas-liquid separator according to claim 2 , wherein the impeller is provided with at least one cylindrical member coaxially attached to the impeller.
9. The gas-liquid separator according to claim 1 , wherein at least one of fluid throttle means, heating means, and accumulation means is inserted in the passage of the suction inlet.
10. The gas-liquid separator according to claim 2 , wherein at least one of fluid throttle means, heating means, and accumulation means is inserted in the passage of the suction inlet.
11. The gas-liquid separator according to claim 7 , wherein at least one of fluid throttle means, heating means, and accumulation means is inserted in the passage of the suction inlet.
12. The gas-liquid separator according to claim 1 , wherein cavitation causing means is inserted in the passage for gas-liquid separation.
13. The gas-liquid separator according to claim 2 , wherein cavitation causing means is inserted in the passage for gas-liquid separation.
14. The gas-liquid separator according to claim 7 , wherein cavitation causing means is inserted in the passage for gas-liquid separation.
15. The gas-liquid separator according to claim 1 , wherein protection means, which allows gas passage but prevents liquid passage, is inserted in the exhaust passage from the exhaust outlet to the vacuum means.
16. The gas-liquid separator according to claim 2 , wherein protection means, which allows gas passage but prevents liquid passage, is inserted in the exhaust passage from the exhaust outlet to the vacuum means.
17. The gas-liquid separator according to claim 7 , wherein protection means, which allows gas passage but prevents liquid passage, is inserted in the exhaust passage from the exhaust outlet to the vacuum means.
18. The gas-liquid separator according to claim 1 , wherein at least a portion of the discharged fluid from the discharge outlet is returned to the suction inlet.
19. The gas-liquid separator according to claim 2 , wherein at least a portion of the discharged fluid from the discharge outlet is returned to the suction inlet.
20. The gas-liquid separator according to claim 7 , wherein at least a portion of the discharged fluid from the discharge outlet is returned to the suction inlet.
