The invention belongs to the field of chemical industry production device and particularly relates to a short pipe supporting type jacket structure reaction kettle. A jacket is arranged on the surface of a reaction kettle body and the surface of a conical head. A through hole is formed in the cellular jacket, and a reinforcing sleeve connected to the surface of the reaction kettle body is fixed in the through hole. According to the short pipe supporting type jacket structure reaction kettle, the pressure bearing capacity of the reaction kettle body and the jacket can be enhanced, the wall thickness of the reaction kettle body is reduced, and improvement of the heat transfer effect is facilitated. Meanwhile, the reinforcing sleeve can constantly change the flow direction and the flow velocity of fluid in the jacket, so that turbulence is formed and an original laminar flow layer is damaged or thinned, and therefore cold and heat exchange is accelerated and the heat transfer effect between the fluid in the jacket and the interior of the kettle body is greatly enhanced.
