The water pump 42 is connected to an annular cooling pipe 44 through a water inlet pipe 43. The annular cooling pipe 44 is connected to a water outlet pipe 45. The water outlet pipe 45 extends out of the reactor 1. When materials are added dropwise, heat can be absorbed and discharged to avoid a sharp rise in temperature when materials are added dropwise, thereby alleviating temperature changes in the reactor 1 and avoiding combustion, explosion, etc.
