The reaction kettle is mainly composed of the kettle body, kettle cover, transmission device, agitator, sealing device, etc.: 1. The shell of the reaction kettle. The shell is composed of a circular cylinder, an upper cover, and a lower head. There are two ways to connect the upper cover to the cylinder. One is to directly weld the cover to the cylinder to form a whole; Another form is to consider easy disassembly and use flange connections. The upper cover has manholes, handholes, and process connections. 2. The stirring device of the reaction kettle is usually installed in the reaction kettle to accelerate the reaction rate, enhance mixing, and improve mass or heat transfer efficiency. It consists of a stirrer and a stirring shaft, which are connected to the transmission device through a coupling.3. The sealing device used in the reaction vessel is a dynamic sealing structure, mainly consisting of packing seal and mechanical seal.

When the aspect ratio is large, multi-layer stirring blades can be used. When the material needs to be heated or cooled during the reaction process, a jacket can be installed on the wall of the reaction vessel, or a heat exchange surface can be set inside the vessel, or heat exchange can be carried out through external circulation.

Intermittent reactor

Flexible operation, easy to adapt to different operating conditions and product varieties, suitable for the production of small batches, multiple varieties, and products with long reaction times. The disadvantage of intermittent kettles is that they require auxiliary operations such as loading and unloading, and the product quality is not easily stable. However, some reaction processes, such as fermentation and polymerization reactions, still face difficulties in achieving continuous production, and batch reactors are still used to this day.
The intermittent operation reactor system adds raw materials to the reactor at a certain ratio, and after the reaction reaches a certain requirement, the materials are discharged at once. The continuous operation reactor system continuously adds raw materials and continuously discharges reaction products. When the operation reaches a steady state, the composition, temperature, and other state parameters of the material at any position in the reactor do not change over time. A semi continuous operation reactor, also known as a semi intermittent operation reactor, is between the above two, usually adding one reactant at once and then continuously adding another reactant. After the reaction reaches a certain requirement, stop the operation and unload the material.The advantage of batch reactors is that the equipment is simple, and the same device can be used to produce multiple products, especially suitable for small batch and multi variety production in industrial sectors such as pharmaceuticals and dyes. In addition, there is no material backmixing in batch reactors, which is beneficial for most reactions. The disadvantage is that it requires auxiliary processes such as loading and unloading, cleaning, etc., and the product quality is not easily stable.
