The utility model additionally provides a kind of compressor, including foregoing exhaust pipe structure.
According to exhaust pipe structure of the present utility model and compressor, by setting in converging transition and divergent segment, exhaust process,
Gas mixture can collide the internal face of blast pipe converging transition so that Oil-gas Separation.Then divergent segment is passed through, air-flow is gradually swollen
It is swollen, finally more equably discharge blast pipe.The relatively existing exhaust process of whole process, its runner is obviously prolonged, and is increased
Collision separation process, effectively improves oil efficiency.
Brief description of the drawings
The accompanying drawing for constituting the part of the application is used for providing further understanding to of the present utility model, of the present utility model
Schematic description and description is used to explain the utility model, does not constitute to improper restriction of the present utility model.In accompanying drawing
In：
Fig. 1 is the axial cross section structure diagram according to exhaust pipe structure of the present utility model.
Description of reference numerals：
10th, converging transition；11st, guiding gutter；20th, divergent segment.
Embodiment
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in figure 1, according to exhaust pipe structure of the present utility model, along airflow direction, what is had inside blast pipe is tapered
Section 10 and divergent segment 20.The utility model is by setting in converging transition 10 and divergent segment 20, exhaust process, and gas mixture can be rushed
Hit the internal face of blast pipe converging transition 10 so that Oil-gas Separation.Then divergent segment 20 is passed through, air-flow gradually expands, more finally
Equably discharge blast pipe.The relatively existing exhaust process of whole process, its runner is obviously prolonged, and is added collision and separated
Journey, effectively improves oil efficiency.
Specifically, the end of converging transition 10 is connected with the head end of divergent segment 20 so that can by the air-flow of converging transition 10
Immediately enter divergent segment 20 to expand, effect is streamed in increase, improve separative efficiency.
Preferably, guiding gutter 11 is set on the inwall of converging transition 10, is on the one hand conducive to improving separating effect；The opposing party
Face, is also beneficial to the oil backflow after separation.It is highly preferred that guiding gutter 11 is spiral stream guidance groove 11, so as to promote gas mixture
Rotation, improves oil-gas separation efficiency under the influence of centrifugal force.
With reference to shown in Fig. 1, in the utility model, converging transition 10 is taper converging transition, and divergent segment 20 is taper divergent segment,
So that air-flow uniform shrinkage and expansion, are also convenient for processing.Usually, the cone angle of taper converging transition is more than the cone of taper divergent segment
Angle, is more beneficial for making oil gas collision separation, strengthens oil efficiency.
The design of the cone angle of taper converging transition, the cone angle of taper divergent segment and guiding gutter 11 needs to consider different type of machines
Extraction flow, and consider the pressure loss.Usually, the principle for choosing cone angle is just on the premise of pressure and flow velocity is met, to the greatest extent
The length of possible increase runner.Definition exhaust pipe length is full-length, is computed, the cone angle of converging transition 10 is at 20 ° to 30 °
Effect is more excellent；Preferably, α is 28 °.It is more excellent that the cone angle beta of divergent segment 20 is selected in 20 ° to 30 ° effects；Preferably, β is 22 °.Guiding gutter
11 design mainly considers to reduce the pressure loss while extending flow channel length.Optimizing guiding gutter 11 can be by channel interior stream
Field carries out analogue simulation, it is ensured that exit velocity is relatively uniform.According to analysis corrections, the guiding gutter 11 of helical wire form is vented most uniform
And the pressure loss is relatively small, reasonably cone angle and guiding gutter 11 are designed, it is ensured that air-flow passes through the flow losses of blast pipe
As small as possible, exhaust is more uniform, and oil-gas separation efficiency is high.
The utility model additionally provides a kind of compressor, including foregoing exhaust pipe structure, so as to improve oil efficiency, no
Can only the overall dimensions of compressor reduced, moreover it is possible to lift the coefficient of performance of compressor.If oil efficiency is sufficiently high, very
External oil can extremely be simplified, reduce package size.
As can be seen from the above description, the utility model the above embodiments realize following technique effect：
According to exhaust pipe structure of the present utility model and compressor, by setting converging transition 10 and divergent segment 20, it was vented
Cheng Zhong, gas mixture can collide the internal face of blast pipe converging transition 10 so that Oil-gas Separation.Then divergent segment 20, gas are passed through
Stream gradually expands, and finally more equably discharges blast pipe.The relatively existing exhaust process of whole process, its runner is obviously prolonged,
And collision separation process is added, oil efficiency is effectively improved.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
