[0025] An inlet distributor of a hydrogenation reactor includes a distribution plate 1 located on the pipeline of the hydrogenation reactor, and a number of inlet distribution components are evenly arranged on the distribution plate 1;

[0026] The inlet distribution component includes a central tube 2 inserted and connected to a distribution plate 1. A number of through holes 3 are provided at the upper end of the central tube 2. A first screw 4 is rotatably connected to the upper side surface of the central tube 2. A round bubble cap 5 is threadedly connected to the first screw 4. A cavity 6 is provided inside the central tube 2. A control plate 7 is slidably connected inside the cavity 6. A number of tooth rows 8 are fixedly installed on the control plate 7. The central tube 2 is provided with a strip-shaped through hole 9 corresponding to the cavity 6. One end of the control plate 7 extending out of the central tube 2 through the strip-shaped through hole 9 is fixedly installed with a moving plate 10. A second screw 11 is threadedly connected to the moving plate 10. The other end of the second screw 11 is rotatably connected to the central tube 2. A sector gear 12 is rotatably connected between the central tube 2 and the cavity 6. The sector gear 12 meshes with the tooth rows 8. A flow limiting plate 13 is fixedly installed on one side of the sector gear 12 located inside the central tube 2. The flow limiting plate 13 is slidably connected to the inner wall of the central tube 2;

[0027] As can be seen from the above description, when the corresponding central tube 2 is installed on the distribution plate 1, before working, by rotating the second screw 11, the position of the moving plate 10 is adjusted to drive the control plate 7 to move up and down. Through the connection between the tooth rows 8 and the sector gear 12, the inclination angle of the flow limiting plate 13 is adjusted. After adjusting to a suitable position, stop rotating.

[0028] As a technical optimization scheme of the present invention, a first knob 14 is fixedly installed at the upper end of the first screw 4;

[0040] Working principle:

[0041] Install the corresponding central tube 2 on the distribution plate 1. Before working, by rotating the second screw 11, adjust the position of the moving plate 10 to drive the control plate 7 to move up and down.
