The stirred tank reactor is mainly composed of a stirrer and a kettle body. The stirrer effectively includes a transmission device, a stirring shaft, an impeller, a kettle body including a cylinder body, a jacket and an inner part, a coil, a draft tube Wait. There are hundreds of kinds of stirred tank reactors used in industry, which can be divided into two types according to the phase state of the reaction materials: a homogeneous reactor and a heterogeneous reactor. Heterogeneous reactors include solid-liquid reactors, liquid-liquid reactors, gas-liquid reactors, and gas-liquid-solid three-phase reactors.
The stirred tank reactor is a study of the mixing and flow conditions of the materials in the reactor. More than 50% of the chemical processes are batch operations in a stirred reactor, which is even higher in small and medium-sized chemical companies, so mixing Improvements in the design and operation of the plant have a major impact on the production process, safety, product quality and energy consumption of chemical production.
Any simple process of the stirred tank reactor may be controlled by one of the above processes, but the possibility of two or more processes is also important. The choice of mixer type and size, speed and method of operation depends on the results of each operation. For example, some operations are best to use a large diameter, low speed agitator, while the other operation is to run a small diameter, fast paddle. If it is an intermittent cycle process, it is necessary to select an optimal solution according to the needs of the entire process.
