In chemical production, the mixing Kettle is not only a simple chemical reaction process, but also physical mass transfer processes such as fluid flow, material heat transfer, mass transfer, and mixing. In the stainless steel reactor, the excitation, steps and speed of the chemical reaction are carried out according to the laws of chemical kinetics. For example, for gas-liquid reactions, the reaction rate is not only related to temperature and concentration, but also related to the size of the phase interface and the diffusion rate between the phases. Regarding the gas-solid reaction, no matter what the conditions are, the gas-phase components must first diffuse on the surface of the solid catalyst, and then chemical reactions take place on the surface of the catalyst. The chemical reaction process is the essential process of reactor work.
Because there are many types of raw materials in chemical reactions, the reaction process is also very complicated, and the requirements for reaction products are also different. In order to meet different reaction requirements, Mixing Kettle has a variety of structure types and sizes, operation methods and operating conditions. They are also different. For example, in a batch-operated reactor, the raw materials are added all at once; while in a continuous-operated reactor, the raw materials are added continuously. Stirring tanks with different structures and sizes and different operating conditions and methods will definitely affect the flow of fluids and the transfer processes of heat, mass, and mixing of materials. The transfer process is an important condition for the realization of the reaction process. Therefore, the working process of Mixing Kettle is the reaction process based on chemical kinetics and the transfer process based on heat transfer, mass transfer, and momentum transfer. The complex process of mutual influence.
