Description

A kind of centrifugal oil eliminator that is used for refrigeration system

Technical field:

The utility model relates to a kind of oil eliminator, especially relates to a kind of centrifugal oil eliminator that is used for refrigeration system.

Background technology:

Oil eliminator is called separator again, and it utilizes the lubricating oil separation of being carried secretly in the refrigerant gas after screen pack or centrifugation will be compressed to come out, and enters condenser to prevent lubricating oil, heat transfer condition is worsened and the thermal efficiency descends.If lubricating oil can not in time be got back to compressor, fault such as may cause that compressor burns.Existing centrifugal oil separator structure adopts the eddy current baffle plate of spiral conducting line to make the refrigerant that enters oil eliminator be rotated down centrifugal flow, realizes refrigerant and oily first separation, realizes secondary separation by the screen pack of gas outlet then.The weak point of this structure when being first separation bigger freezing olesome under centrifugal action, just be thrown toward the outside, and secondary separation is less freezing olesome.If the use filter screen, oil droplet just can be realized separating with refrigeration oil when having only the refrigeration oil particle of minority to bump against with screen cloth, more is that the mixture of refrigerant and refrigeration oil enters in the condenser by the screen cloth hole, can not realize efficient separation.

The utility model content:

The purpose of this utility model provides a kind of centrifugal oil eliminator that is used for refrigeration system with regard to being the weak point that exists at prior art, and it can make the refrigeration oil that is entrained in the refrigerant realize efficient the separation in cylindrical shell.

For achieving the above object, the centrifugal oil eliminator that is used for refrigeration system of the present utility model includes cylindrical shell, upper end cover, escape pipe and eddy current baffle plate, wherein, upper end cover is positioned at cylindrical shell one end, escape pipe stretches in the cylindrical shell, and the eddy current baffle plate is fixed on the escape pipe, and the place, gas outlet of described escape pipe is provided with impeller, the front end of impeller links to each other with the noise reduction baffle plate, and the noise reduction baffle interior is provided with screen cloth.

Preferred as technique scheme is provided with the circular arc vane more than three in the described impeller, the inboard of blade and the gas outlet of impeller are tangent.

Preferred as technique scheme, described impeller front outer is provided with the folding ear.

Preferred as technique scheme, described noise reduction baffle plate includes rack and is positioned at the retainer ring of rack upper end, and wherein, the rack middle part is provided with the flange that cooperates with the impeller base that is convexly set in the impeller front end.

Preferred as technique scheme has the intermediate ribs that is used for fixing screen cloth in the described retainer ring.

The beneficial effects of the utility model are: the cyclonic separation technology is adopted in its secondary separation, the mixture that makes refrigerant after the first separation and refrigeration oil during through impeller blade level rotate at a high speed, not separated oil component mixture rotational time is longer, the refrigeration oil particle constantly gets rid of laterally under centrifugal action, thereby realizes efficient the separation.
