Abstract

An oil separate and collect device ( 1 ) has a horizontally elongated container body ( 2 ) disposed in a horizontal orientation. A gas inlet ( 3 ), through which compressed gas containing oil flows into the container body ( 2 ), is located at an upper part on one end side of an interior of the container body ( 2 ). A gas outlet ( 4 ), through which the compressed gas from which oil has been separated flows out of the container body ( 2 ), is located at an upper part on the other end side of the interior of the container body ( 2 ). A partition board ( 5 ) divides a lower part of the interior of the container body ( 2 ) into a first chamber ( 6 ) on a gas inlet ( 3 ) side and a second chamber ( 7 ) on a gas outlet ( 4 ) side.

First claim

1 . An oil separate and collect device for separating and collecting oil from compressed gas, which contains the oil and has been discharged from an oil-cooled compressor, the oil separate and collect device comprising:
a horizontally elongated container body disposed in a horizontal orientation; a gas inlet which is located at an upper part on one end side of an interior of the container body and through which the compressed gas containing the oil flows into the container body; a gas outlet which is located at an upper part on the other end side of the interior of the container body and through which the compressed gas from which the oil has been separated flows out of the container body; and a partition board configured to divide a lower part of the interior of the container body into a first chamber on a gas inlet side and a second chamber on a gas outlet side.

2 . The oil separate and collect device according to claim 1 , wherein
the container body is a cylindrical body with both ends being closed, and the partition board is disposed at a position between 0 (mm) and 0.5 φD (mm) inclusive with respect to an origin, assuming that a drum diameter of the container body is φD (mm), a position of a section, which is closest to the first chamber, of an inner edge of an opening edge of the gas outlet in a central axis direction of the container body is the origin, and the gas inlet side is positive.

3 . The oil separate and collect device according to claim 1 , wherein
the container body is a cylindrical body with both ends being closed, and a height of the partition board is larger than a height of an oil level of the oil, which has accumulated in the first chamber, and equal to or smaller than 0.8 φD (mm), assuming that a drum diameter of the container body is φD (mm).

4 . The oil separate and collect device according to claim 1 , wherein
the container body is a cylindrical body with both ends being closed, and a section, which is closest to the first chamber, of an inner edge of an opening edge of the gas outlet in a central axis direction of the container body is disposed at a position 0.7 φD (mm) or more away from a side wall on a gas outlet side of the container body, assuming that a drum diameter of the container body is φD (mm).

5 . The oil separate and collect device according to claim 1 , wherein trapping unit configured to trap a bubble of the oil is provided at a lower part of the second chamber.

6 . The oil separate and collect device according to claim 1 , wherein a float valve is provided at a bottom part of the second chamber.

7 . The oil separate and collect device according to claim 1 , wherein
an elbow inflow pipe, through which the compressed gas containing the oil flows into the container body along a direction that does not face the first chamber, is provided in the container body, and the gas inlet is an opening on a downstream side of the elbow inflow pipe.

8 . The oil separate and collect device according to claim 1 , wherein
an elbow outflow pipe, through which the compressed gas in the container body flows out of the container body from a side wall side on the gas outlet side, is provided in the container body, and the gas outlet is an opening on an upstream side of the elbow outflow pipe.
