Abstract

The invention provides an in-kettle temperature control method and system for a continuous granulation reaction kettle and a medium, and the method comprises the following steps: presetting that the reaction kettle is provided with a plurality of sections of heating chambers, and obtaining the reaction temperature of a lithium battery material and the total section number of the heating chambers; the rated temperature of the lithium battery material flowing out of each section of heating chamber is formulated based on the reaction temperature and the total section number; the current temperature of the lithium battery material flowing out of each section of heating chamber is obtained; the temperature difference between the current temperature of each section of heating chamber and the corresponding rated temperature is calculated; if the absolute value of the temperature difference of the heating chamber is larger than a first preset threshold value, the heating chamber is marked as a reference heating chamber; obtaining current environment data, and calculating the updated rated temperature of each heating chamber through a dynamic adjustment model based on the temperature difference and the remaining section number of the reference heating chamber; and adjusting the heating power of each heating chamber according to the updated rated temperature. According to the invention, the temperature in the kettle can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of reaction kettle tail gas treatment, in particular to a continuous granulation reaction kettle tail gas treatment method, system and storage medium. Background technique [0002] Lithium batteries are batteries that use lithium metal and lithium alloy as negative electrode materials and use a non-aqueous electrolytic solution. Due to the very unstable chemical properties of lithium metal, the reactor for processing lithium batteries needs to meet very high requirements. The existing reaction kettle generally includes a rotary drum, a heater, a driving motor and a heating furnace body. The heating furnace body is composed of upper and lower parts. The rotary drum and the heater are arranged inside the heating furnace body. During the generation process, a heater is used to supply heat to promote the temperature increase in the heating furnace, thereby providing the reaction temperature of lithium metal. H...
