Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, it is used for installed in compressor body 10 according to compressor exhaust pipe of the present utility model 30
Exhaust end, specifically includes exhaust tube body 31, and there is the exhaust passed through for compressor discharge air-flow to lead in exhaust tube body 31
Road 311, compressor exhaust pipe 30 also includes centrifugal gas-liquid separation device, and centrifugal gas-liquid separation device is arranged on exhaust passage 311
It is internal.In the compressor exhaust pipe 30 that the utility model is provided, by inside the exhaust passage 311 of compressor exhaust pipe 30
Centrifugal gas-liquid separation device is set, during so as to through the air-flow of compressor exhaust end discharge by compressor exhaust pipe 30, can be passed through
Centrifugal gas-liquid separation device in exhaust passage 311, produces centrifugal motion, in air-flow in the presence of centrifugal gas-liquid separation device
The oil droplet for containing is thrown on the wall of exhaust passage 311 under the action of the centrifugal, and oil droplet is separated with gas in realizing air-flow, nothing
The structure that oil eliminator need to be improved just can further improve oil efficiency.
Embodiment 1：
As shown in figure 3, in the compressor exhaust pipe 30 of the utility model first embodiment, realizing in compressor exhaust pipe
In 30, the centrifugal gas-liquid separation device specially spiral board 33 that lubrication oil droplet with air-flow separate.Spiral board 33 is included relative to row
Impeller and the impeller axle of installation impeller that gas airflow direction is obliquely installed, the air-flow passed through from compressor exhaust pipe 30 is by leaf
During wheel under the guiding of impeller the componental movement with centrifugal direction, the oil droplet that is in a liquid state in air-flow is realized under the influence of centrifugal force
Separate, the structure without improving oil eliminator just can further improve oil efficiency, meanwhile, the presence of spiral board 33 can also make
Come from the Diffusion of gas stream of the discharge of compressor exhaust pipe 30, it is ensured that exhaust flow field is more uniform.Installed to spiral board 33
When, the central axis of spiral board 33 be set to it is parallel with the direction of airflow, while being fixedly connected on the interior of exhaust passage 311
Wall.It is pointed out that direction of the central axis of spiral board 33 not necessarily with airflow is parallel, in actual use,
The central axis of spiral board 33 can also realize the gas-liquid separation work(of spiral board 33 with the direction of airflow in low-angle angle
Energy.
It is the inwall that centrifugal gas-liquid separation device is fixedly connected on exhaust passage 311, can is in centrifugation gas specifically
Screw thread is opened up with the inwall of exhaust passage 311 on liquid separating apparatus, is led between centrifugal gas-liquid separation device and the inwall of exhaust passage 311
The mode for crossing threaded connection is fixed.It is of course also possible to be to pass through clamping between centrifugal gas-liquid separation device and exhaust passage 311
Mode is connected.
Because the air velocity discharged in compressor exhaust pipe 30 is big, in order to be further ensured that compressor in the utility model
