Description

Technical Field

[0001] The invention relates to the technical field of waste resin treatment, in particular to a temperature control system of a reactor for treating waste resin by molten salt oxidation. Background Art

[0002] In the treatment of waste resin by molten salt oxidation, the temperature control in the reactor directly affects the treatment effect and safety. If the temperature of the reactor is not properly controlled, on the one hand, it may cause the reaction system to overheat and cause dangerous situations, such as explosions or other safety accidents. On the other hand, the oxidation reaction will not be fully carried out, and the decomposition rate of the waste resin will be greatly slowed down, resulting in low treatment efficiency, extended treatment time, and increased treatment costs. At the same time, different molten salt oxidation waste resin treatment stages require different temperature conditions to promote the chemical reaction in order to improve the oxidation efficiency and treatment effect of the waste resin. Inappropriate temperature will lead to an increase in by-products and a decrease in the treatment effect. Therefore, in the process of molten salt oxidation waste resin treatment, the temperature control of the reactor is particularly important.

[0003] At present, the temperature control of the reactor used for molten salt oxidation waste resin treatment usually sets a fixed temperature value in the reactor, and then the control system adjusts the temperature in the reactor according to this fixed value. This temperature control method is single and inflexible, and cannot make timely adjustments according to the actual changes in the reaction process, resulting in low reaction efficiency or reduced product quality. Moreover, the fixed temperature control method may cause the system to be in a high or low temperature state for a long time, resulting in low energy efficiency and increased production costs.
