Abstract
An oil separator is provided with a housing having an inlet for air, and an expansion chamber located inside the housing. The oil separator introduces air containing oil that has passed through the inlet into the housing, and separates and recovers the oil from the introduced air. The transverse cross-sectional area of the expansion chamber is larger than the opening area of the inlet. The oil separator is further provided with a collected liquid storage portion that is located below the expansion chamber and collects the separated oil, a liquid communication portion having a communication hole that connects the expansion chamber to the collected liquid storage portion, and a mounting and dismounting mechanism for mounting and dismounting the collected liquid storage portion to and from the housing.
Claims6
A system comprising:
- a compressor configured to compress air and to supply compressed air;
- an air dryer configured to dry the compressed air supplied from the compressor and to supply dried compressed air, the air dryer comprising a supplying line for supplying the dried compressed air and an exhaust line for discharging purge air;
- and
- an oil separator connected to the exhaust line, the oil separator comprising:
- a housing including an inlet for introducing the purge air from the air dryer;
- and
- an expansion chamber provided in the housing, wherein
- the oil separator is configured to introduce the purge air into the housing through the inlet to separate and recover the oil from the introduced purge air,
- the transverse cross-sectional area of the expansion chamber is greater than the opening area of the inlet, and
- the oil separator further includes
- a collected liquid storage portion located below the expansion chamber, wherein the collected liquid storage portion is configured to store the separated oil,
- a liquid communication portion having a communication hole that connects the expansion chamber and the collected liquid storage portion with each other, and
- a mounting and dismounting mechanism for mounting the collected liquid storage portion to and dismounting the collected liquid storage portion from the housing.
An oil separator comprising:
- a lid including an inlet for introducing purge air from an air dryer and an outlet for discharging cleaned air;
- a plurality of expansion chambers arranged next to one another in a vertical direction;
- a housing mountable to the lid;
- and
- a mounting and dismounting mechanism for allowing the lid to be detachable with respect to the housing, wherein
- the oil separator causes the purge air to flow into the housing and strike an impingement member to separate oil from the purge air, thereby recovering liquid containing oil, and the oil separator discharges cleaned air, and
- a through hole, which permits the purge air introduced through the inlet to flow vertically downward, is formed between the expansion chambers.
