The outer peripheral surface of the second barrel section 25 is provided with a first spiral groove 27. The first spiral groove 27 is used to improve the eddy or swirl flow performance of the medium, thereby improving the injection or spray performance of the nozzle 4.

[0026] The diverter section 13 includes a diverter body 28, a second flange 29, a first diverter hole 30, and a second diverter hole 31.

The conical surface at the lower end of the diverter body 28 is provided with a plurality of circumferentially distributed second diverter holes 31.

[0027] The first injection port 14 includes a first injection chamber 32, a first injection hole 33, and a connecting groove 34. The outlet end of the first injection chamber 32 is provided with the first injection hole 33. The first injection hole 33 is a gradually expanding hole.

[0030] When the connector 16 is a rigid connector, the axial position of the diverter 13 is fixed. When the connector 16 is a spring 38, the diverter 13 can be moved axially by designing the spring's elastic force and controlling the pressure of the medium flowing into the nozzle 4 (the diverter 13 can move downward when the medium pressure exceeds the spring's elastic force), thereby partially or completely covering the first diverter hole 30, thereby adjusting the injection amount and on / off of the second injection hole 24.

[0031] The magnitude of the elastic force of spring 38 and the pressure of the medium flowing into the nozzle can be determined according to design requirements. For example, if the elastic force of spring 38 is greater than the pressure of the medium flowing into nozzle 4, diverter 13 is fixed and does not move. At this point, the deacidified or deodorized medium is split into two paths through diverter 13: one path enters the inner cavity of intermediate liner 12 through second diverter hole 31 and is then ejected through first ejection port 14; the other path enters the gap between the outer circumference of intermediate liner 12 and the inner circumference of first barrel section 18 through first diverter hole 30 and is then ejected through second ejection port 19.

The shielding and deflecting plate 40 is tilted relative to the axis of the nozzle 4 . The shielding and deflecting plate 40 is used to shield and deflect part of the injection flow of the second injection hole 24 .

[0033] The present invention provides a refining device for oil production. By improving the nozzle structure design of the deacidification or deodorization device, compared with the nozzles in the prior art, it can improve the eddy or swirl flow properties of the medium (such as grease, oil, etc.), thereby improving the spraying or spraying performance of the nozzle, and the spraying or atomization range is wider and more uniform, thereby effectively improving the deacidification or deodorization effect.
