Description

technical field [0001] The invention relates to the technical field of active prevention and control measures for rapid and uniform addition of uncontrolled diluents and inhibitors under stirring failure conditions, and specifically relates to a method for quickly and uniform addition of uncontrolled diluents and inhibitors when stirring fails. Background technique [0002] Most production devices in the petrochemical field are equipped with stirring devices. During the production process of petrochemical devices, stirring mainly plays the role of dispersing materials, enhancing mass transfer and heat transfer. Stirring failure widely exists in the production process of the petrochemical industry. Once the stirring fails, it will cause local monomer overconcentration or local overheating in the reaction system, which will cause the reaction system to deviate from the normal reaction conditions. If no effective measures are taken , will lead to serious consequences. [0003]...

AI Technical Summary

Problems solved by technology

However, at present, most production enterprises add diluents and inhibitors into the reaction system through the material pipeline on the top of the device reactor. Due to the failure of the stirring device, the diluents and inhibitors cannot be uniformly dispersed, especially some polymers with larger molecular weights. During the production process, the viscosity of the reaction system is relatively high, so diluents and inhibitors cannot be quickly and evenly dispersed into the reaction system, and it is difficult to prevent the reaction from getting out of control.
