　　I. Overview of Stirred Reactor
　　Stirring reactor is a reactor with stirring function. Stirring reactor according to the different forms of stirring, there are ordinary stirring reactor, magnetic stirring reactor. According to the different stirring speed, there are low-speed reactor, medium-speed reactor and high-speed reactor. Stirred reactor provides favorable conditions for material reaction according to stirrer. CHARACTERISTICS OF STIRRING REACTOR
　　The main characteristics of stirring reactor are different stirring forms, such as blade stirring, propelling stirring, style stirring, anchor stirring, scraping stirring and so on. Two-blade agitation is the most basic slurry type, which is dominated by horizontal circulation at low speed, radial flow at high speed and up-down circulation with baffles. It is suitable for mixing, homogenizing, blending, dissolving, heat transfer or crystallization of low viscosity liquids, or working in laminar flow under high viscosity, using multi-layer, large diameter and low speed agitation. Inclined blade stirring can be made into 24?, 45?, or 60?, inclined angle, with axial and radial shunts. The spiral blade is suitable for mixing, homogenizing, heat transfer and reaction of medium and high viscosity. General multi-layer combination use. It has the characteristics of twin screw belt slurry. Curved-edged oblique blade propeller is a type of oblique blade slurry. The bottom of the slurry is close to the elliptical surface of the vessel. The vertical surface of the blade plane and the rotating axis is also called the inclination 45?. It acts as a scraper and runs at low speed. It can be operated in the over-flow or laminar flow zone. Turbine agitator runoff agitator is opened, which has a wide range of rotational speed, viscosities and high shear force and turbulent diffusion ability. Because it has no disc, it will not hinder the mixing of upper and lower blades. It can form a large convective circulation in the baffle groove. It is especially suitable for shear dispersion operation. Because of its good circulation and shear capacity, it can also be used for general solid dissolution, reaction, heat transfer, emulsification, crystallization and solid suspension operation. Axial flow agitator with inclined blade turbine has better convective circulation ability and turbulent diffusion ability. It is suitable for mixing, dispersion, particle crystallization, reaction, dissolution, solid-liquid suspension, heat transfer and other operations. With stabilizer structure, it is mainly used near the critical point of axle design, where the axle needs radial centralization. Frame blade scraper type, in laminar flow operation, to prevent the deposition of heavy components at the bottom, suitable for crystallization, extraction, washing and other processes, but also for the heat transfer process of high viscosity liquid. Three-blade propeller is the most typical axial-flow agitator with high liquid discharge and low shear performance, while baffle or draft tube has stronger axial circulation. Because of its strong circulation ability and low power consumption, its advantages can be best reflected by its application in large capacity homogeneous and mixing process. It is widely used in low viscosity liquid heat transfer, reaction, solid-liquid ratio hourly suspension, dissolution and other processes.

Screw agitator is a slow agitator, which operates in laminar flow zone. It is suitable for mixing and heat transfer of medium and high viscous liquids. The screw agitator has small diameter, large axial thrust, a guide cylinder on the screw, and strengthened axial flow, forming a downward-upward circulation inside and outside the guide cylinder. Frame stirring is suitable for mixing, heat transfer and reaction of medium and high viscous liquids. Often operated in laminar state, horizontal circulation, such as folded or angle steel blades, can increase the eddy current near the blade. The stirring range can be increased by adding vertical blades and crossbeams on the blades as required.
