| titleOfInvention | N,N'-dicyclohexylcarbodiimide production reaction system |
| abstract | The utility model belongs to the technical field of production of N,N'-dicyclohexylcarbodiimide, in particular to a reaction system for the production of N,N'-dicyclohexylcarbodiimide, wherein a stirring shaft in the reaction kettle is from top to bottom Dispersing discs, multi-layer stirring paddles and anchor frame stirring rods are arranged in sequence, and the bottom of the reactor is connected with the upper part of the reactor through a circulating pump and a circulating pipeline. There is a heat exchanger on the line; the outer wall of the reaction kettle is provided with a jacket, the outlet of the jacket is connected with the inlet of the jacket through the jacket circulation pump, the steam-water mixer and the temperature sensor in turn, and the evaporator is connected with the steam-water through the induced draft fan. The mixer is connected; the top exhaust port of the reactor is connected with the multi-stage spray absorption tower in series. In the utility model, the heat exchanger is arranged on the secondary circulation line, and the steam in the evaporator is introduced into the evaporator through the steam-water mixer, so that the temperature of the materials participating in the reaction is more controllable, thereby improving the production efficiency and product quality. |
