When oil eliminator work when, by compressor discharge refrigerating agent containing oil air-flow by refrigerant inlet 5 into
Entering into cylinder 1, refrigerant gas stream rotates downwards along the circular passage formed between 1 inner wall of 9 outer wall of guide shell and cylinder, this
When refrigerant gas stream in the biggish oil droplet of particle just under the action of centrifugal force and gravity along 1 inner wall of cylinder rotation fall on cylinder 1
In the oil storage pool 18 of bottom.Refrigerant gas stream through initial gross separation continues to flow downward, and strikes the baffle plate of 1 lower section of cylinder
15, under the blocking of baffle plate 15, part olesome is separated；By the blocking of baffle plate 15, refrigerant gas stream is opened
Beginning flows up, and enters and carries out further Oil-gas Separation in guide shell 9.Under the action of gas-liquid net 11, most oil
Drop is all separated by gas-liquid net 11, is fallen on radiation shield 10 by oil leaking hole 14 under gravity, is finally collected in cylinder
In 1 lower section oil storage pool 18 of body.By the refrigerant gas stream of gas-liquid net 11, in blocking under oil screen 12 acts on for 9 top of guide shell, make
Minute quantity is not separated by the olesome that gas-liquid net 11 is isolated, and oil gas separation is further increased；And pass through excessively oil
Refrigerant gas stream by refrigerant outlet 6 discharge utilize.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
The range of implementation, therefore the displacement of its equivalent assemblies, or according to equivalent changes and modifications made by the utility model patent protection scope,
It should still belong to the scope that the utility model claims book is covered.
