The invention relates to a safety compensation device used in a polymerizer, which comprises a polymerizer body, an inner heater hot oil pipeline inlet, an expansion joint, a polymerizer inner heater, a salt inlet pipeline, a salt inlet valve, an inner heater hot oil pipeline outlet, a stirrer stirring shaft, stirrer blades, a motor, a speed reducer and a mechanical seal, low-temperature hot oil enters the heater in the polymerization kettle from the hot oil pipeline inlet and the expansion joint of the inner heater and is gradually heated to the reaction temperature, and after reaction, high-temperature hot oil flows out of the heater in the polymerization kettle from the expansion joint and the hot oil pipeline outlet of the inner heater on the other side and is slowly cooled. The reaction kettle is reasonable in structure, greatly reduces the material adhesion amount in the material reaction process, reduces the accumulation of carbides, reduces black grains of products, improves the quality of the product
