Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

As shown in fig. 1 to 4, the high-efficiency reliable hydrogenation reaction kettle of the present embodiment comprises a kettle body 1, a steam heat exchange cavity 2 is connected to the outer side of the kettle body 1, the upper part and the lower part of the steam heat exchange cavity 2 are respectively connected with an upper steam inlet 21 and a lower condensed water outlet 22, a feed inlet 11 is arranged at the upper end of the kettle body 1, a discharge outlet 13 is connected to the lower end of the kettle body 1, a hydrogen inlet pipe 12 is connected to the upper end of the kettle body 1, the lower end of the hydrogen inlet pipe 12 is positioned above the bottom of the kettle body 1, a drive shaft 3 is rotatably connected to the kettle body 1 through a bearing, the upper end of the drive shaft 3 is connected to the drive end of a drive motor 4, the lower end of the drive shaft 3 is connected to a rotating shaft 5 through a coupler, an impeller is connected to the rotating shaft 5, the drive motor 4 is connected to the kettle body 1 through a bracket, a leakage-proof box 6 is, and a sleeve 611 is arranged between the two pore plates 61 in a matching manner with the driving shaft 3, a sealing ring 612 is arranged between the sleeve 611 and the driving shaft 3, a hydrogen sensor 631 is arranged in the lower box 63, the upper box 62 is connected with an exhaust pipe 622, a pumping plate is arranged between the two pore plates 61, the pumping plate comprises a left pumping plate 64 and a right pumping plate 65, the left pumping plate 64 and the right pumping plate 65 are respectively connected with a left traverse driving part 641 and a right traverse driving part 651, the left traverse driving part 641 and the right traverse driving part 651 are driving cylinders, and a sealing strip 66 is arranged between the left pumping plate 64 and the right pumping plate 65.
