The invention discloses a carbon fiber production polymerization reaction control device and a method thereof. The device comprises a DCS control system, and a feeding mechanism and a temperature adjusting mechanism which are controlled by the DCS control system to move; the temperature adjusting mechanism comprises a temperature three-way control valve V3, temperature control valves V1 and V2 respectively arranged on two circulating waterways, and temperature control valves V4 and V5 respectively arranged on two cooling waterways; waters controlled by the valves V1, V2 and V3 are mixed, one part of the obtained water mixture directly enters a temperature adjusting interlayer outside a reaction kettle, and the remaining part flows to one inlet of the valve V3; water controlled by the valveV5 flows to another inlet of the valve V3; water obtained after mixing in the valve V3 flows to the temperature adjusting interlayer outside the reaction kettle; and a mixing adjusting module for controlling the opening degrees of the valves V2, V3 and V4 is arranged in the DCS control system. The device and the method realize the continuous and stable control of all parameters, so the uniformityof a polymerization solution is guaranteed.
