Chemical reactor is a device for chemical reaction, usually used for the preparation of chemical reagents, drugs, dyes, food additives and other products. This equipment is an indispensable part of chemical production. Its main functions are mixing, reaction, evaporation and heat transfer. So, what is the working principle of the chemical reaction kettle?

1. working principle of the

reaction kettle is mainly through the heating, cooling, stirring, mixing and heat transfer process, control the temperature, pressure, chemical composition and concentration of parameters. The reactor is usually composed of a container body, a rotor, a stirrer, a heater, a refrigerator, a lifting device, an instrument, and a control system. Its structure is shown in the figure below. The working principle of the

reactor is as follows:

① Feeding: The reactor first mixes the reaction materials, assist materials or reversible agents fully before adding.

② Mixing: In the reaction kettle, the added materials will be stirred and impacted by the rotating rotor, so that the chemical reaction is more complete, thereby improving the reaction efficiency.

③ heat transfer: the material added in the reaction kettle will generate a lot of heat in the reaction process, so it is necessary to set up a heater or refrigerator in the reaction kettle, so that the temperature can be determined and controlled, so as to ensure the smooth progress of the reaction.

④ Separation: After the reaction is completed, the reaction material in the reactor is separated by the lifting device for subsequent processing.

2. How to use

(1) Before feeding, first check whether the temperature, pressure, water level, medium and other parameters of the reactor are normal to ensure safety.

(2) When feeding, chemical substances should be added according to the demand, and the order should be paid attention to to avoid dangerous situations such as explosion.

(3) When stirring, the rotating speed and stirring angle should be controlled to avoid affecting the reaction efficiency.

(4) The reaction process in the reactor should be common to detect important parameters such as temperature, pressure, residual amount of reaction materials, etc., to avoid overheating, overpressure, insufficient reaction materials, etc.

(5) After the reaction is completed, the reaction material needs to be separated for subsequent treatment.

3. summary

chemical reactor is an essential equipment in the chemical production process, its working principle is simple and easy to understand, the use method is practical and simple, but in the use of the process also need to follow the relevant provisions, strengthen safety measures, to ensure stable operation of equipment, improve production efficiency, guarantee the quality of work.
