The working process of the stainless steel reactor
The working process of the stainless steel reactor: In chemical production, the reactor 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 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 chemically react 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, the structure and size of stainless steel reactors are also varied, operation methods and operations The conditions 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. Reactors of different structures and sizes, and different operating conditions and methods, will inevitably affect the fluid flow state and the heat transfer, mass transfer, and mixing process of materials. The transfer process is a necessary condition for the realization of the reaction process. Therefore, the working process of the reactor 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.
The main function of the stainless steel reactor is to provide a reaction place and maintain certain conditions. The process of chemical reaction is carried out in a predetermined direction to obtain qualified reaction products. Almost all process equipment includes reactors. Therefore, how to select a suitable reactor series, establish the best operating conditions and design a reasonable and reliable stainless steel reactor to meet the needs of the ever-developing process industry is of great significance.
