U-tube reactor
The U-shaped tubular reactor is equipped with porous baffle or stirring device in the tube to strengthen the heat and mass transfer process. The U-shaped tube has a large diameter, which increases the residence time of materials and is suitable for reactions with slow reaction rate.
Titanium equipment of multi tube parallel tube reactor
Multi tube parallel tubular reactor is generally used for gas-solid reaction, such as gas-phase hydrogen chloride and acetylene. In the multi tube parallel reactor equipped with solid catalyst, vinyl chloride is generated by reaction, and gaseous nitrogen hydrogen mixture synthesizes ammonia in the multi tube parallel reactor equipped with solid iron catalyst.
Piston flow reactor
Performance characteristics:
1. The length diameter ratio of the reactor is large.
2. It is assumed that there is no reverse mixing (backmixing) between the materials entering the reactor at different times.
3. The reactant flows along the length of the tube. The reaction time is a function of the length of the tube, and its concentration changes from one section to another with the flow direction.
Kettle reactor
Kettle reactor is also known as tank reactor and pot reactor. It is a relatively simple structure in various types of reactors. Reactor with wide application. It can be used in homogeneous reaction and heterogeneous reaction dominated by liquid phase. If the heterogeneous liquid phase, liquid-solid phase, gas-liquid phase and gas-liquid-solid phase are equal.
The structure of kettle reactor is mainly composed of shell, stirring device, shaft seal and heat exchange device.
Intermittent kettle
Batch reactor, or batch reactor. Flexible operation, easy to adapt to different operating conditions and product varieties, suitable for small batch, multi variety and long reaction time production. The disadvantage of batch kettle is that it needs auxiliary operations such as loading and unloading, and the product quality is not easy to be stable. However, in some reaction processes, such as fermentation and polymerization, it is still difficult to achieve continuous production. Up to now, batch reactors are still used.
