Dehydrogenation reactor

The utility model belongs to the technical field of reactors, and particularly relates to a dehydrogenation reactor which comprises a reactor, a top cover and a catalyst bin, the bottom end of the top cover is rotatably connected with an L-shaped feeding pipe, the L-shaped feeding pipe is communicated with the internal space of the catalyst bin, one end of the L-shaped feeding pipe is fixedly connected with a connecting pipe, and the other end of the L-shaped feeding pipe is connected with the catalyst bin. The bottom end of the top cover is fixedly connected with a supporting cover, the inner wall of the supporting cover is slidably connected with a lifting plate, the lifting plate is slidably connected to the side wall of the L-shaped feeding pipe, and a catalyst is uniformly fed through rotation of the L-shaped feeding pipe, so that the catalyst can participate in a reaction in time during feeding, the reaction efficiency is improved, and the reaction time is shortened. The pressure generated by the reacti
