Tower reactor

The utility model provides a tower reactor and relates to the field of tower reactors. The tower kettle reactor comprises a kettle body, a tower pipe is arranged at the upper end of the kettle body, a rack is fixedly connected to the kettle body, a motor is installed and connected to the rack, the output end of the motor is fixedly connected with a connecting shaft, and the connecting shaft is rotationally connected with the kettle body. According to the tower reactor provided by the utility model, the motor is started to enable the output end of the motor to drive the rotating shaft to rotate, so that the top plate drives the drawing rod to slide relative to the pipe wall of the vertical pipe, the piston at the lower end of the drawing rod slides back and forth in the vertical pipe, and the output quantity of vaporized reactants can be accurately controlled by utilizing negative pressure in the vertical pipe; a good reaction effect is ensured, and waste is effectively avoided; and after the top plate moves u
