Abstract

Disclosed is an apparatus for separating gas and liquid. The apparatus for separating gas and liquid includes a housing, a rotating shaft provided inside the housing, a drive unit configured to rotate the rotating shaft, a rotating cone mounted at the rotating shaft to rotate about the rotating shaft and having a diameter decreasing from an upper end to a lower end thereof, a fixed cone fixed in the housing to be spaced apart from the rotating cone and having a diameter decreasing from an upper end to a lower end thereof, and a scraper configured to remove scale generated in at least one of the fixed cone and the rotating cone, based on the rotation of the rotating shaft.

First claim

The invention claimed is:

1. An apparatus for separating gas and liquid comprising:
a housing;
a rotating shaft provided inside the housing;
a drive unit configured to rotate the rotating shaft;
a rotating cone mounted at the rotating shaft to rotate about the rotating shaft and having a diameter decreasing from an upper end to a lower end thereof;
a fixed cone fixed in the housing to be spaced apart from the rotating cone and having a diameter decreasing from an upper end to a lower end thereof; and
a scraper configured to remove a scale generated in the fixed cone, based on the rotation of the rotating shaft,
wherein the scraper is fixed in the rotating shaft or the rotating cone, and configured to remove the scale generated in the fixed cone while rotating with the rotating shaft or the rotating cone,
wherein the scraper extends from the rotating shaft or the rotating cone toward the fixed cone,
wherein the scraper is in direct contact with the fixed cone to remove the scale generated in the fixed cone, and
wherein the scraper remains in contact with the fixed cone while rotating with the rotating shaft.

2. The apparatus for separating gas and liquid of claim 1 , wherein the scraper extends to face an outer circumferential surface of the fixed cone.

3. The apparatus for separating gas and liquid of claim 1 , wherein the scraper extends to face an inner circumferential surface of the fixed cone.

4. The apparatus for separating gas and liquid of claim 1 , wherein the scraper extends parallel to the rotating shaft.

5. The apparatus for separating gas and liquid of claim 1 , wherein the scraper extends at a predetermined angle with respect to the rotating shaft.

6. An apparatus for separating gas and liquid comprising:
a housing;
a rotating shaft provided inside the housing;
a drive unit configured to rotate the rotating shaft;
a rotating cone mounted at the rotating shaft to rotate about the rotating shaft and having a diameter decreasing from an upper end to a lower end thereof;
a fixed cone fixed in the housing to be spaced apart from the rotating cone and having a diameter decreasing from an upper end to a lower end thereof; and
a scraper configured to remove a scale generated in the rotating cone, based on the rotation of the rotating shaft,
wherein the scraper is fixed in the fixed cone, and configured to remove the scale generated in the rotating cone while the rotating cone is rotated,
wherein the scraper extends from the fixed cone toward the rotating cone,
wherein the scraper is in direct contact with the rotating cone to remove the scale generated in the rotating cone, and
wherein the scraper remains in contact with the rotating cone while rotating with the rotating shaft.

7. The apparatus for separating gas and liquid of claim 6 , wherein the scraper extends to face an outer circumferential surface of the rotating cone.

8. The apparatus for separating gas and liquid of claim 6 , wherein the scraper extends to face an inner circumferential surface of the rotating cone.

9. The apparatus for separating gas and liquid of claim 6 , wherein the scraper extends parallel to the rotating shaft.

10. The apparatus for separating gas and liquid of claim 6 , wherein the scraper extends at a predetermined angle with respect to the rotating shaft.

11. An apparatus for separating gas and liquid comprising:
a housing;
a rotating shaft provided inside the housing;
a drive unit configured to rotate the rotating shaft;
a rotating cone mounted at the rotating shaft to rotate about the rotating shaft and having diameter decreasing from an upper end to a lower end thereof;
a fixed cone fixed in the housing to be spaced apart from the rotating cone and having a diameter decreasing from an upper end to a lower end thereof;
a first scraper configured to remove a scale generated in the fixed cone, based on the rotation of the rotating shaft; and
a second scraper configured to remove scale generated in the rotating cone, based on the rotation of the rotating shaft,
wherein the first scraper is fixed in the rotating shaft or the rotating cone, and configured to remove the scale generated in the fixed cone while rotating with the rotating shaft or the rotating cone,
wherein the first scraper extends from the rotating shaft or the rotating cone toward the fixed cone,
wherein the first scraper is in direct contact with the fixed cone to remove the scale generated in the fixed cone, and
wherein the first scraper remains in contact with the fixed cone while rotating with the rotating shaft.

12. The apparatus for separating gas and liquid of claim 11 , wherein the second scraper is fixed in the housing or the fixed cone, and configured to remove scale generated in the rotating cone while the rotating shaft is rotated.

13. The apparatus for separating gas and liquid of claim 11 , wherein the second scraper extends from the housing or the fixed cone toward the rotating cone, and
the second scraper is spaced apart at a predetermined distance from the rotating cone, based on the thickness of scale to be formed in the rotating cone.
