Super complete! Multiple reactor forms and characteristics
Chemical reactor is the core equipment of chemical production, the form of reactor has a very important impact on chemical production, can directly affect the production safety and product quality. According to the characteristics of the reactor form, it can be mainly divided into kettle reactor, tube reactor, tower reactor, bed reactor, micro reactor and so on.
Kettle reactor
The kettle reactor is also known as reactor and pot reactor. It is the simplest and most widely used of all types of reactors, and is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and other fields. It can be used to carry out homogeneous reactions or non-homogeneous reactions mainly in liquid phase, such as liquid-liquid phase, liquid-solid phase, gas-liquid phase, gas-liquid-solid phase, etc.
Kettle reactors are characterised by a wide range of temperatures and pressures, adaptability, flexibility of operation, easy control of temperature and concentration during continuous operation and homogeneous product quality. These reactors are usually most commonly used under relatively mild operating conditions, such as atmospheric pressure, low temperature and below the boiling point of the material. When the reaction conditions are more severe (e.g. high temperature, high pressure, strong corrosion, etc.), special kettle reactors can also be used for production.
The main structure of the kettle reactor consists of the kettle body, stirring device, transmission device, shaft sealing device and heat exchange device.
Kettle reactors can be divided according to their mode of operation into
(1) Intermittent kettle, also known as intermittent kettle reactor, is characterised by flexible operation and can be adapted to different operating conditions and product varieties, and is particularly suitable for the production of small batches, multiple varieties and long reaction times. The disadvantage of intermitten
