The understanding of the reactor refers to the stainless steel container with physical or chemical reaction.
Through the structural design and parameter configuration of the container, the functions of heating, evaporation, cooling and low-speed mixing required by the process can be realized.
With the pressure requirements in the reaction process, the design requirements of the vessel are also different.
The production must be processed, tested and commissioned in strict accordance with the corresponding standards.
The reactor is used in petroleum, chemical industry, rubber, pesticide, dye, medicine, food and other industries as a pressure vessel to complete the process of vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and so on.

The reactor can be divided into intermittent operation and continuous operation according to operation. Generally, jacket heat exchanger can also be installed with built-in coil heat exchanger or basket heat exchanger.
An external circulating heat exchanger or a reflux condensation heat exchanger can also be provided. Stirring can be accomplished by stirring the slurry or by bubbling with air or other inert gases.
It can be used for liquid phase homogeneous reaction, gas-liquid phase reaction, liquid-solid phase reaction and gas-solid-liquid three-phase reaction.
Pay attention to controlling the reaction temperature, otherwise there will be a big accident, unless your reaction is a reaction with small thermal effect. Intermittent operation is relatively simple, and continuous operation requires high requirements.
The reactor can realize the functions of heating, evaporation, cooling and low-speed mixing required by the process. The reactor is used in petroleum, chemical industry, rubber, pesticide, dye, medicine and food, as well as pressure vessels used to complete vulcanization, nitrification, hydrogenation, alkylation, polymerization, condensation and other process processes, such as reactor, reaction tank, decomposition tank, polymerization kettle, etc.
Materials are generally carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel, Inconel) alloys and other composite materials.
The extended data reactor is mainly composed of kettle body, kettle cover, transmission device, agitator, sealing device, etc.
The shell of the reactor. The shell is composed of a cylinder, an upper cover and a lower cover. There are two connection modes between the upper cover and the cylinder. One is that the cover and the cylinder are directly welded into one; Another form is to consider convenient disassembly and can be connected with flange.
The upper cover is provided with manhole, handhole and process nozzle.
The upper cover is provided with manhole, handhole and process nozzle. The stirring device of the reactor is in the reactor. In order to speed up the reaction speed, strengthen mixing and enhance the effect of mass transfer or heat transfer, the reactor is generally equipped with a stirring device.
The utility model is composed of an agitator and a mixing shaft, which are connected with a transmission device through a coupling.
The sealing device used in the reactor is a dynamic sealing structure, mainly including packing seal and mechanical seal.
