[0019] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0020] The utility model discloses a nozzle for an oil-gas separator. The nozzle is arranged at the feed end of the oil-gas separator, and an inclined baffle is arranged at the end of the nozzle body to change the speed and direction of the oil-gas mixture of the oil-gas separator, thereby improving the pre-separation effect of the nozzle and solving the problem of low working efficiency of the existing oil-gas separator.

[0022] The nozzle body 101 is installed in the oil-gas separator 200 , the inclined baffle 102 is arranged at the outlet end of the nozzle body 101 , and one end of the nozzle body 101 where the inclined baffle 102 is installed is arranged in the oil-gas separator 200 .

[0023] A channel is provided in the nozzle body 101, and the channel is used to communicate with the inside of the oil-gas separator 200. The inner wall of the inclined baffle 102 is arranged at an acute angle with the central axis 105 of the channel, so that the local cross-sectional area of ​​the channel near the outlet end is arranged to decrease, and the cross-sectional area of ​​the outlet end of the channel is smaller than the cross-sectional area of ​​the inlet end, wherein the inner wall of the inclined baffle 102 can be Figure 1 The plane structure shown is set at an acute angle with the central axis 105 of the channel, or it can be a curved surface set along a predetermined path, the path of the curved surface is set at an acute angle with the central axis 105 of the channel, and the decreasing cross-sectional area setting of the channel refers to the decreasing cross-sectional area setting from the feed end to the discharge end of the nozzle body 101.

[0024] In this embodiment, the outlet end surface 103 of the nozzle body 101 is arranged perpendicular to the central axis 105 of the channel.

[0025] In this embodiment, the nozzle body 101 and the oil-gas separator 200 are welded together.

[0026] Working principle: First, the end of the nozzle body 101 with the inclined baffle 102 installed is eccentrically inserted into the oil-gas separator 200, and then the direction of the inclined baffle 102 and the angle of the outlet end face 103 of the nozzle body 101 in the oil-gas separator 200 are adjusted. Figure 5 The inclined baffle 102 is arranged on one side of the nozzle body 101 close to the central axis of the oil-gas separator 200, and then the nozzle body 101 and the oil-gas separator 200 are fixedly connected by welding.

[0027] During operation, when the compressed oil-gas mixture is input into the oil-gas separator 200 through the nozzle 100, the speed and direction of the oil-gas mixture in the oil-gas separator 200 can be changed by utilizing the obliquely arranged inner wall of the oblique baffle 102 to obtain a cyclone effect, thereby improving the pre-separation effect of the nozzle 100.

[0028] In the second embodiment, the connection mode between the nozzle body 101 and the oil-gas separator 200 is changed on the basis of the first embodiment, so that the oil-gas separator 200 can replace different nozzles 100 during the test phase to test out the best cyclone effect.

[0030] The outlet end surface 103 of the nozzle body 101 and the inner wall of the inclined baffle 102 are perpendicular to the first plane. Figure 1-3 The outlet end face 103 of the nozzle body 101 shown also intersects with the inclined baffle 102 at a first axis, the first axis is parallel to the longitudinal axis, and the outlet end face 103 of the nozzle body 101 is rotated around the first axis to be inclined at a predetermined angle, so that the angle between the outlet end face 103 of the nozzle body 101 and the central axis 105 of the channel is set vertically or at an acute angle.

[0031] In this embodiment, the nozzle body 101 and the oil-gas separator 200 are detachably connected. Figure 1 The nozzle body 101 is also provided with a flange 104 . The nozzle body 101 is inserted into the oil-gas separator 200 . The nozzle body 101 is detachably connected to the oil-gas separator 200 via the flange 104 and bolts.

[0032] Through the detachable connection between the nozzle body 101 and the oil-gas separator 200, the same oil-gas separator 200 can be replaced with a nozzle 100 with a different inclined baffle 102 and an outlet end face 103 of the nozzle body 101 during the test, thereby changing the speed and direction of the oil-gas mixture entering the oil-gas separator 200, and then using the corresponding nozzle 100 according to the exhaust volume of different air compressors to obtain the best rotation effect.
