Background
The lubricating oil plays an important role in safe and efficient operation of an air conditioning system and mainly comprises lubrication, cooling, flushing, sealing, vibration reduction, unloading and protection. However, in extreme conditions, the lubricant oil in the compressor may be mixed with the refrigerant vapor into the circulation system in the form of droplets, which may adversely affect the energy efficiency of the refrigeration system and the service life of the compressor.
The vertical oil separator is typically centrifugal and utilizes centrifugal force to separate oil and gas. However, the conventional vertical oil separator has a limited rotation space, and the inner cylinder and the outer cylinder are generally arranged coaxially, so that the ascending oil-gas mixture and oil drops falling from the filter screen form a pair, and the oil drops with smaller particle sizes are difficult to separate.

Further, the filter component comprises a plurality of filter screens, the filter screens are sequentially arranged in the U-shaped outer cylinder in an inclined mode, and an oil guiding pipe is arranged at the bottom end of the filter component. Preferably, the number of all filter screens is 2.

A U-shaped vertical oil separator comprises a U-shaped outer cylinder 4,U, wherein one side of the outer cylinder 4 is provided with an air inlet, and the other side is provided with an air outlet; an inner cylinder 2 is arranged in one side of the U-shaped outer cylinder 4, the inner cylinder 2 is arranged on one side close to the air inlet, and a filtering component is arranged on the other side; an oil drain port is arranged at the bottom of the U-shaped outer cylinder body 4. The air inlet is provided with an air inlet pipe 1, the air inlet pipe 1 is horizontally arranged on the left upper side of the U-shaped outer cylinder 4 along the tangential direction, and the end part of the air inlet pipe 1 extends to the surface of the inner cylinder 2; so as to ensure that the oil-gas mixture enters the U-shaped outer cylinder 4 along the tangential direction of the cylinder.
The inner cylinder 2 is a solid cylinder and is coaxial with the vertical space at one side of the U-shaped outer cylinder 4; the upper end of the inner cylinder 2 is fixed at the upper end of the vertical space at the left side of the outer cylinder; the length of the inner cylinder 2 is the same as the length of the vertical space at the left side of the outer cylinder body, the length of the inner cylinder is not smaller than 5 times of the diameter of the air inlet, and an oil collecting net 3 is arranged on the inner wall of the vertical space at one side of the U-shaped outer cylinder body 4. Preferably, the length of the oil collecting net 3 is the same as that of the inner cylinder 2, and the top of the oil collecting net is arranged above the air inlet.
The inner diameter of the U-shaped outer cylinder 4 is at least 3 times the inner diameter of the air inlet pipe 1. The difference between the outer diameter of the inner cylinder 2 and the inner diameter of the U-shaped outer cylinder 4 is 0.3-0.4 of the inner diameter of the U-shaped outer cylinder 4. The filter component comprises a plurality of filter screens 8, the filter screens 8 are sequentially arranged in the U-shaped outer cylinder 4 in an inclined mode, and an oil guiding pipe 7 is arranged at the bottom end of the filter component. Preferably, the number of all the filter screens 8 is 2. The liquid oil droplets which are not separated in the primary oil separation process are filtered by two filter screens 8 in the vertical space on the left side of the outer cylinder, which is the secondary oil separation process. The oil guiding pipe 7 is a semi-hollow cylindrical oil guiding pipe 7, and oil drops on the filter screen fall to the bottom of the outer cylinder body along the oil guiding pipe 7 under the action of gravity.
In a specific implementation, the included angle between the filter screen 8 and the inner wall of the U-shaped outer cylinder 4 is 38 degrees. The bottom of the U-shaped outer cylinder body 4 is provided with an oil outlet pipe 5 through an oil discharge port, an impurity filter screen 6 is arranged in the oil outlet pipe 5, and oil drops falling from the left side and the right side are collected and discharged.

The inner cylinder 2 is coaxially arranged in the left vertical section of the outer cylinder body, and an annular space is formed between the inner cylinder 2 and the outer cylinder body.
As shown in fig. 3: the oil-gas mixture entering horizontally from the air inlet makes high-speed vortex downward movement in the annular space at the left side of the oil separator under the action of high pressure. At this time, under the action of centrifugal force, the gaseous refrigerant is separated from the liquid lubricating oil, the lubricating oil adheres to the surface of the oil collecting net 3 to form a liquid oil film, and under the action of gravity, the lubricating oil flows downwards and is collected to the bottom of the oil, which is an oil separation process.
As shown in fig. 3: after the oil-gas mixture passes through the oil content once, the oil-gas mixture enters the right side of the oil separator and vertically rises under the action of pressure. During the primary separation process, a small amount of unseparated lubricating oil droplets with smaller diameters are attached to the surface of the filter screen 8 when passing through the filter screen 8I and the filter screen II, and then fall to the vicinity of an oil outlet through an oil guide pipe 7 at the bottom of the filter screen 8 under the action of gravity, which is a secondary oil separation process.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
