[0146] First, by determining the thermodynamic parameters of the preloaded reactants and defining the internal and external blade speeds of the multi-stage spiral guide assembly and the initial parameters of the dynamic jet cooling module based on these parameters, the cooling system is matched to the reactant characteristics and the internal structure of the synthesis reactor. This customized configuration makes the cooling process more efficient and can quickly respond to temperature changes during the reaction process. Second, by identifying and zoning the internal structure of the synthesis reactor, the concept of a partitioned synthesis reactor is established, which provides a basis for subsequent temperature data collection and analysis. Based on the internal and external blade speeds and the collected zone temperature data, the local overheating area within the synthesis reactor is accurately determined. The precise positioning provides a clear target for subsequent control measures. The local overheating area is mapped to the multi-stage spiral guide assembly, and the speed difference of the mapped spiral blades is calculated to determine the speed control command. By adjusting the spiral blade speed, the fluid dynamic characteristics of the local area are directly affected, thereby achieving effective temperature control. At the same time, the regional viscosity of the local overheating area is calculated, and the angle control command of the target adjustment nozzle of the dynamic jet cooling module is determined accordingly, further enhancing the targeted and efficient cooling effect. Therefore, the present invention can improve the internal temperature control effect of the synthesis reactor.
