The present invention provides a kind of hexamethylene diamine synthesis reaction system, which includes hexamethylene diamine circulation flow reactor, catalyst sedimentation slot, catalyst circulation pipe three parts.It is wherein equipped with guide shell in hexamethylene diamine circulation flow reactor, inside reactor can be divided into reaction zone, move hot-zone, vapor-liquid separation area, liquid circulation area.In catalyst sedimentation slot, the reaction solution come from hexamethylene diamine circulation flow reactor enters the air deflector in the middle part of catalyst sedimentation slot, liquid is disperseed in air deflector, the gas of entrainment is released, catalyst heavy phase is detached with hexamethylene diamine oil phase, catalyst heavy phase is concentrated under the action of settling block, is used for circulation and stress；Light phase obtains the hexamethylene diamine oil phase for being practically free of catalyst.Catalyst circulation pipe makes fluid density improve by the effect of cooling water in chuck, is maintained cycle liquid in pipe and normally declines, catalyst is enable to recycle. |
