Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, a chlorination reactor for pesticide production comprises a reactor body 1, a jacket 2 wrapped outside the reactor body 1, and a vent pipe 5, wherein a heating element (not shown) is arranged in the jacket 2, and the vent pipe 5 is used for introducing chlorine gas.

The center of the kettle body 1 is vertically provided with a self-suction stirrer 3, the self-suction stirrer 3 comprises a stirring shaft 301 and a plurality of groups of hollow impellers 302 which are spaced from top to bottom, a vent pipe 5 penetrates through the outer wall of the kettle body 1 to enter the kettle body 1, the tail end of the vent pipe 5 is communicated with a gas distribution disc 6, and the gas distribution disc 6 is arranged below the tail end of the self-suction stirrer 3 and close to the bottom of the kettle body 1.

The gas distribution plate 6 comprises an annular pipe 601 which is hermetically communicated with the tail end of the vent pipe 5, and a plurality of groups of uniform gas nozzles 602 which are arranged in the annular pipe 601, the gas nozzles 602 are hermetically communicated with the annular pipe 601, and chlorine gas is input through the vent pipe 5 and is sprayed into the kettle body 1 through the gas distribution plate 6.
