When the oil-gas mixture enters the cylinder body through the air inlet bent pipeline, the speed of the oil-gas mixture is reduced due to the resistance of the pipeline, the steering and the sudden space expansion, and most of oil is separated due to the great reduction of the air flow speed, so that the first separation is formed. The oil-gas mixture is guided by the air inlet bent pipeline to blow to the top of the end socket and returns after being blocked by the top end socket, the air flow is further decelerated in the process, a large amount of oil drops are settled and separated, the wall surface of the top end socket can also absorb a large amount of engine oil particles, and oil flows to the bottom of the cylinder along the arc surface to form a second separation. Set up multichannel in the barrel and keep off the oil baffle, block and cut off the air current, make the mixed oil gas flow along the route that keeps off the oil baffle and set for to reduce the velocity of flow, a large amount of machine oil particles sedimentation separation, keep off the oil baffle can block and adsorb a large amount of machine oil particles at this in-process, and flow to the barrel bottom along vertical wall, form the separation of third. Set up a high performance filter screen in the barrel middle section, the air current is slowed down when passing the filter screen, and wherein most remaining machine oil particle is further adsorbed and subsides the separation and come out, forms fourth separation, and the filter screen can filter the filth in the mixed gas-liquid simultaneously. The rear path of the filter screen is provided with a high-efficiency detachable filter element, the filter element is fixed on the support, the air flow enters the filter element through the holes on the support, and the filter element filters and separates out most of residual micro oil drops in the air flow to form a fifth separation path.

Refrigerant gas after the first five separation passes through the top or the side exhaust port to be discharged, the inner side of the cylinder body of the side exhaust port is provided with a shielding structure, namely, the inside of the cylinder body corresponding to the side exhaust port 12 is provided with an exhaust oil baffle assembly 19, so that the phenomenon that trace oil accumulated on the wall of the cylinder body for a long time is discharged along with the refrigerant from the exhaust port after being collected is avoided.

The bottom of the barrel 1 is provided with a plurality of oil discharge ports 20 for discharging accumulated oil and oil stains.

Each section of the cylinder 1 is provided with a liquid sight glass 21 for observing the inside of the equipment and the oil condition of each section.

And the tail end socket 3 is provided with an access hole flange 25, the access hole flange 25 is provided with a blind cover 26, and the blind cover 26 is provided with a handle 27, so that the filter element is convenient to replace and maintain.

The utility model mainly utilizes the difference of physical density of the refrigerant gas and the engine oil and the adsorption effect of the separation element to separate the engine oil in the refrigerant gas. The high-pressure oil-gas mixture enters the equipment through the air inlet assembly, and the gas flow speed is greatly reduced through the diameter expansion and the steering of the air inlet pipeline, so that most of oil drops are separated. The oil-gas mixture flowing out of the air inlet pipe mouth impacts on the top end enclosure and turns back after being blocked by the end enclosure, the air flow further decelerates in the process, a large amount of oil drops are settled and separated out, the wall surface of the end enclosure can also absorb a large amount of engine oil particles, and oil flows to the bottom of the container along the arc surface to form a second separation channel. The mixed oil gas changes the route and reduces the velocity of flow many times under the block of oil baffle, and oil baffle can block and adsorb a large amount of machine oil particles at this in-process to along vertical wall subside to the container bottom, form the separation of third, most machine oil has been separated out this moment. The remaining oil particles are largely retained by the screen assembly as the refrigerant gas passes through the screen assembly, and the screen retains a substantial portion of the dirt. The gas flow rate through the filter screen is greatly reduced, the impact on the filter element is greatly reduced, and the filter element can finally filter the refrigerant gas. The content of the engine oil in the discharged refrigerant gas can be controlled below 3 PPM. Clean refrigerant gas can be discharged out of the oil separator through the top exhaust port and the side exhaust port and enters the condenser for cooling, and the exhaust oil retaining assembly is bowl-shaped and protects the side exhaust port, so that trace oil accumulated on the wall of the container for a long time is prevented from being collected and then discharged along with the refrigerant from the exhaust port.
