The invention relates to a cooling crystallization control method and device, electronic equipment and a system, and the system comprises a crystallization kettle which comprises a tank body, and a solution to be crystallized is accommodated in the tank body; an image acquisition device which is arranged above the to-be-crystallized solution and is used for shooting the to-be-crystallized solution in the tank body in real time to obtain a video image and identifying the video image to obtain a crystal growth state of the corresponding to-be-crystallized solution; and control equipment which is electrically connected with the image acquisition device and the crystallization kettle and is used for controlling the crystallization generation process of the solution to be crystallized in the crystallization kettle according to the crystal growth state. According to the invention, the crystallization process of each stage is ensured to be smoothly and stably carried out, and high purity and uniform and stable batch quality of the crystallized finished product are ensured to the greatest extent.
Description
technical field [0001] The present application relates to the technical field of chemical engineering, in particular to a cooling crystallization control method, device, electronic equipment and system. Background technique [0002] The crystallization method is an operation method in which the solubility of each component in the mixture is different in the same solvent or the solubility is significantly different in hot and cold environments, and the crystallization method is used to separate and purify; cooling crystallization refers to the use of refrigeration equipment to cool the saturated solution. The solute that changes greatly with the temperature will be precipitated in the form of crystals, achieving the purpose of product purification and mass-liquid separation. [0003] At present, the control technology of the crystallization process mainly includes: [0004] (1) Control the crystallization process by controlling the crystallization temperature or setting grad...
