Online evaluation method for operation safety risk of full-mixed-flow reaction kettle

The invention provides an online evaluation method for the operation safety risk of a full-mixed-flow reaction kettle. The method is used for risk evaluation of dynamic operation of the exothermic reaction, and the whole set of work comprises the steps of defining a range, collecting safety data, determining safety conditions and critical limit values, and finally determining a coefficient for indicating safety deviation in the operation process, namely a total real-time safety index of the reaction kettle. According to the method, the real-time safety total index for evaluating the temperature of the reaction kettle is provided, the safety risk of the reaction kettle caused by reaction temperature rise and the safety risk of concentration accumulation of the reaction kettle caused by reaction temperature drop are considered at the same time, and warning is provided for operation of the reaction kettle. The evaluation method is simple in implementation process, and can be used for safety risk online evaluatio
