Description
Technical field
The utility model relates to the annex in a kind of air-conditioning refrigeration system, particularly a kind of oil eliminator.
Background technology
In general, oil eliminator in refrigeration system is arranged between the exhaust outlet and condenser of compressor, be used for separate compressors get rid of gases at high pressure in lubricating oil, do not make excessive oil enter condenser and evaporimeter, to prevent compressor machine oil starvation, otherwise can cause very large infringement to compressor, a large amount of oil of while enters condenser and evaporimeter can impact the heat transfer effect of condenser and evaporimeter again, makes systematic energy efficiency ratio low.
Existing refrigeration system oil eliminator, the mode that adopts one-stage centrifugal to separate, the gaseous refrigerant of oil-containing enters oil eliminator from oil content air inlet pipe, under the effect of centrifugal force, oil droplet is assembled at oil content cylinder body bottom, get rid of by bottom oil exit pipe, the gaseous refrigerant after centrifugal escapes and enter in refrigeration system condenser through inner barrel from top vent.
There is following shortcoming in above-mentioned oil eliminator: in the time that gaseous refrigerant flow is large, the flow velocity that enters inner barrel is high, the centrifugal force that in cold-producing medium, oil droplet is subject to is just large, if while flow velocity exceedes certain limit and can cause that again the oil droplet that is gathered in drum surface is rolled in gaseous refrigerant again, so the flow velocity of gaseous refrigerant has an optimum separating ranges; When gaseous refrigerant flow hour, the flow velocity that enters inner barrel is low, and in cold-producing medium, to be subject to centripetal force little for oil droplet, so its inferior separating effect.Especially in tangible frequency conversion system, compressor air-discharging adjustable range is large, and above-mentioned oil eliminator can only meet separative efficiency higher in its certain limit.
Utility model content
The technical problems to be solved in the utility model is: a kind of oil eliminator is provided, makes the range of flow of its accessible refrigerating agent containing oil large.
In order to solve the problems of the technologies described above, the utility model comprises that at least three layers with upper shell, all cylindrical shell upper port are all sealed, the lower port height of every layer of cylindrical shell reduces successively from inside to outside, the lower port of innermost layer cylindrical shell is provided with screen pack, the lower port sealing of other cylindrical shell, the upper port of innermost layer cylindrical shell is provided with exhaust outlet, the lower port of outermost layer cylindrical shell is provided with oil drain out, except innermost layer cylindrical shell, the upper end sidewall of its outer cylinder body is provided with tangential air inlet, and the lower port of middle cylindrical shell is provided with the oil guide pipe that leads to outermost layer cylinder body bottom.
In order to obtain best cost performance, described cylindrical shell has three layers, is respectively inner barrel, middle cylindrical shell and the outer cylinder body of separating, and the upper port of three layers of cylindrical shell is all fixed on a upper cover plate, and the lower port of outer cylinder body is fixed with lower cover.
For the ease of isolated oil is discharged to this separator, described exhaust outlet is arranged on upper cover plate, and lower cover is provided with oil-collecting bag, and oil drain out is arranged on the bottom of oil-collecting bag, and oil guide pipe extend in oil-collecting bag.
In order to obtain good filter effect, the order number of described screen pack is not less than 200 orders.
The beneficial effects of the utility model are: the utility model has the advantages that in the time that capacity is large, active is centrifugation in outer cylinder body, and a middle cylindrical shell and screen pack auxiliary separating is from less oil droplet; When capacity hour, outer cylinder body centrifugation helps out, and in the middle of main utilization, the centrifugation of cylindrical shell, utilizes the mode of multi-stage separation under different flow, all can obtain higher separating effect to meet.

Detailed description of the invention
A kind of oil eliminator as shown in Figure 1, comprise upper cover plate 12, cover plate 11, lower cover 10, oil-collecting bag 9 and three layers of cylindrical shell, three layers of cylindrical shell are respectively inner barrel 6, middle cylindrical shell 4 and the outer cylinder body 1 of separating, the upper port of three layers of cylindrical shell is all fixed on upper cover plate 12, and upper cover plate 12 center is provided with the exhaust outlet 3 communicating with inner barrel 6.The lower port height of every layer of cylindrical shell reduces successively from inside to outside, the lower port of inner barrel 6 is provided with screen pack 5, the middle lower port that separates cylindrical shell 4 is sealed by cover plate 11, the lower port of outer cylinder body 1 is sealed by lower cover 10, oil-collecting bag 9 is arranged on the middle part of lower cover 10 and communicates with the lower port of outer cylinder body 1, the bottom of oil-collecting bag 9 is provided with oil drain out 8, outer cylinder body 1 is provided with tangential air inlet 2 with the middle upper end sidewall that separates cylindrical shell 4, and the middle lower port that separates cylindrical shell 4 is provided with the oil guide pipe 7 leading in oil-collecting bag 9.
One deck or which floor the middle cylindrical shell 4 that separates also can arrange more, can play better separating effect.
Operation principle: in the time that the gaseous refrigerant that contains lubricating oil tangentially enters outer cylinder body 1 along the air inlet 2 on outer cylinder body 1 along arrow A, under the effect of centrifugal force, make oil separate from cold-producing medium and be gathered in outer cylinder body 1 bottom, in the middle of tangentially entering from middle cylinder body 4 tops through the gaseous refrigerant of outer cylinder body centrifugation, separate the interior continuation centrifugation of cylindrical shell 4, gaseous refrigerant after separation is through the bottom screen pack 5 of inner barrel 6, discharge from top vent 3 along arrow C after filtering, in the middle of being deposited on, the oil that secondary centrifuging separates and the oil of strainer filtering separates cylindrical shell 4 bottoms, import outer cylinder body 1 bottom by oil guide pipe 7, and discharge along arrow B through oil-collecting bag 9 and oil drain out 8, between oil drain out 8 and compressor, can connect oil return pipe, get back to compressor oil groove through oil return pipe again.
