Centrifugal unit for oil-gas separation and horizontal efficient oil-gas separator

Abstract

The invention relates to oil-gas separation equipment in refrigeration systems, in particular to a centrifugal unit for oil-gas separation and a horizontal efficient oil-gas separator. The centrifugal unit comprises a centrifugal chamber for allowing an oil-gas mixture to perform centrifugal motion, a material inlet for conveying the oil-gas mixture is arranged at the material inlet end of the centrifugal chamber, and a collision plate for oil-gas separating is arranged in the discharging direction of the centrifugal chamber. A drum body of the oil-gas separator is provided with a material inlet pipe for conveying the oil-gas mixture and an exhaust pipe for discharging gas state separated materials, the centrifugal unit, a maze type deoiling unit, a first filter unit and a second filter unit are sequentially arranged between the material inlet pipe and the exhaust pipe in the drum body, and the material inlet pipe is communicated with the material inlet of the centrifugal chamber in the centrifugal unit. The horizontal efficient oil-gas separator can more thoroughly separate oil from gas under the condition of larger discharge capacity and larger oil consumption of a compressor, and is good in separation effect and high in separation efficiency.

Description

Technical field [0001] The invention relates to an oil and gas separation equipment in a refrigeration system, in particular to a centrifugal unit and a horizontal high-efficiency oil and gas separator for oil and gas separation. Background technique [0002] The refrigeration compressor requires a large amount of refrigerating oil to lubricate the mechanical running parts of the compressor and take away the heat generated in the compressor. In this process, the refrigerating oil and the refrigerant in the compressor are vaporized into oil and gas The mixture leaves the compressor. At this time, there must be a high-efficiency oil-gas separator to separate the refrigerated oil from the oil-gas mixture. On the one hand, it is to ensure that the refrigerated oil returns to the oil storage tank of the compressor to prevent the compressor from freezing The lack of oil causes malfunctions, thereby prolonging the life of the compressor; on the other hand, it is also to prevent the refr...

Problems solved by technology

If the oil consumption of the compressor is high, the oil droplets with larger particle size will inevitably increase the burden on the filter when passing through the filter, and when the filter is gradually filled with oil droplets, the filter will also have a greater impact on the oil-air mixture. At this time, if the displacement of the compressor increases, the flow rate of the oil-air mixture will also increase, which will further reduce the horizontal oil-air separation that only relies on filtration and gravity to separate refrigeration oil.
