Initiator adding system

The utility model relates to an initiator adding system, which comprises a pipeline mixer and a reactor, the pipeline mixer is communicated with the reactor, the pipeline mixer is used for realizing the mixing of an initiator and a material and inputting the mixed solution into the reactor, and the reactor is used for carrying out chemical reaction; according to the initiator adding system provided by the utility model, the pipeline mixer is adopted to replace a traditional independently-arranged mixing container, so that on one hand, an initiator and a material are mixed more sufficiently anduniformly, and the content of the initiator can be controlled more accurately; and on the other hand, the retention time of the initiator and the material before entering the reactor is shorter, andthe consumption of the initiator before entering the pipeline mixer is lower, so that a good polymerization effect can be achieved in the reactor, the consumption of the initiator can be effectively saved, and the cost is redu
