Introduction to the function and principle of the reactor stirrer

Classification: Industry Information

There are many components inside the reactor, among which the stirrer is the core component of the reactor. During the material mixing reaction process in the reactor, stirring is carried out through the rotation of the stirrer and the stainless steel shaft.

1. What is a reactor stirring device?

       Inside the reactor, there are many components, among which the stirrer is the core component of the reactor. During the material mixing reaction process in the reactor, stirring is carried out through the rotation of the stirrer and the stainless steel shaft.

2. What is the function of the reactor stirrer?

       The reactor stirrer is an important part of the reactor. During the reaction process in the reactor, it mainly serves the following functions:

       1. Promote the mutual dissolution of liquids. The mutual dissolution and mixing of two or more liquids, as well as the uniform stirring of liquids, should be able to distinguish whether there is a chemical reaction in the homogeneous liquid mixture. In the absence of a chemical reaction, it is usually referred to as the mixing of mutual solutions. When a chemical reaction occurs between two or more mutual solutions, stirring should also be performed to accelerate the reaction or complete it.

       2. Disperse immiscible liquids. Another function of the stirrer is to make immiscible liquids come into contact and disperse in a container, which is beneficial for the transfer and exchange reactions of substances, or for preparing suspensions and emulsions. The role of stirring is to reduce the size of droplets, thereby increasing the relative contact area.

       3. Facilitate gas-liquid contact. This stirring causes the gas to form small bubbles, which are evenly dispersed in the liquid phase, forming a stable dispersion, enhancing the liquid's absorption of gas, and promoting chemical reactions between the gas phase and the liquid phase.

       4. Disperse solid and liquid phases. The stirring in the reactor has a wide range of applications, including the preparation of uniform suspensions, the dissolution of solids, chemical reactions between solids and liquids, washing solids in liquids, and the precipitation of crystals from saturated liquids.

       5. Enhance heat transfer. Some liquids require heating or evaporative cooling during the reaction process. Stirring increases the heat transfer rate of the liquid, making the temperature of the liquid more uniform.

3.Reactor manufacturersIntroduction to the principle of the stirrer

       The reactor stirrer is an important component of the reactor, and its complex principles involve many processes such as fluid dynamics, heat transfer, mass transfer, and chemical reactions. In simple terms, the working principle of the reactor stirrer is: using the impeller as the main component, mechanical energy is applied to the liquid through the movement of the impeller with the rotating shaft, promoting the movement of the liquid. When the stirrer rotates, it transfers mechanical energy to the fluid, forming a high turbulence fully mixed area near the stirrer and generating a high-speed jet that drives the liquid to circulate within the stirring container.
