Original title: Structure and working principle of reactor (reaction kettle) Source: Coal Chemical Knowledge Base The reactor is a device for realizing a reaction process, and is used for realizing a liquid-phase single-phase reaction process and a liquid-liquid, gas-liquid, liquid-solid, gas-liquid-solid and other multiphase reaction processes. Stirring devices (mechanical stirring, airflow stirring, etc.) Are often installed in the device. When the ratio of height to diameter is large, multiple layers of stirring blades can be used. When the materials need to be heated or cooled in the reaction process, a jacket can be arranged on the wall of the reactor, or a heat exchange surface can be arranged in the reactor, or heat exchange can be carried out through external circulation. By mode of operation 1. Batch reactor or batch reactor Flexible operation, easy to adapt to different operating conditions and product varieties, and suitable for the production of products with small batch, multiple varieties and longer reaction time. The disadvantaactor is equal, the reactant concentration and chemical reaction rate at any point in the reactor do not change with time, but only with the length of the tube. 2. Tubular reactor has small volume,wiped film distillation, large specific surface and large heat transfer area per unit volume, which is especially suitable for reactions with large thermal effect. 3. Because the reaction speed and flowidence time of the material is increased, so that the U-tube can be applied to a reaction with a slow reaction rate. Multi-tube parallel tubular reactor 5 Tubular reactors with multiple tubes in parallel are generally used for gas-solid phase reactions, for example,wiped film evaporator, gas-phase hydrogen chloride and acetylene react in a reactor with multiple tubes in parallel filled with a solid phase catalyst to produce ctor Tower equipment for realizing gas-liquid phase or liquid-liquid phase reaction process, including packed tower, plate tower, bubble tower, jacketed glass reactor ,cbd crystallization equipment, etc. Bubble column reactor 1 Bubble column reactor is widely used in medium-speed, slow-speed reactions and reactions with large heat release, in which liquid phase also participates in the reaction. For example, t make a contribution to the cause of green environmental protection!
