Different types of stirrer
Different types of stirrer in reactor is a important chapter for chemical engineers , this is very important for those who want to make her career as Chemical process engineer or Technology transfer engineer. Selection of suitable types of agitator for reactor is a big role of chemical engineer. For experience chemical engineer it is very easy to select types of agitator for reactor , but for fresh engineer it is difficult task , so we will try to help them with our experience .
Agitation is chapter which is useful for desired mixing , more heat transfer and to get a good crystallization .
Selection of stirrer
We know the classification of stirrer. There is basic criteria for selection of suitable agitation as per process requirement .It is difficult to say exact method for selection of stirrer , but you can considered following points while a suitable types of agitator for reactor.
- MOC of stirrer
- Application of stirring
- viscosity of stirring material
- flow direction
- Required RPM for your application
Material of construction for Stirrer
Material of construction for stirrer play a significant role in selection of required stirring system. You have to check compatibility of stirrer MOC with your material . This compatibility also help you in selection reactor or vessel MOC too . You van check acidity or alkality of material for selection of suitable stirrer MOC. You have to check compatibly of material with agitator MOC at required temperature , concentration.
Application of types of agitator for reactor
This is also one of the main point while selecting agitator. There are two main applications of agitator , one is homogenous mixing and second is heat transferring. Example when you have to do crystallization mostly anchor type agitator used in chemical industry .
Viscosity of material
You have to consider viscosity of material while selecting agitator. It also play a vital role in agitation.
Different Types of stirrer
different types of stirrer in reactor are as follows ,
- Anchor type stirrer
- Paddle type of stirrer
- Propeller type stirrer
- Turbine types of stirrer
- Pitch blade type stirrer
Paddle type agitator
This type of stirrer used when we need uniform laminar flow .You can use this type of reactor in different types of reactor. If you don’t know the classification of reactor used in chemical plants , you can read following article .
Used for mixing of Solid and mixing of slurry .The main advantage of paddle type of agitator for reactor is it can use for heavy duty and we can use 2 to 5 blades. Main disadvantage of is its high power consumption ability and its mixing quality.
Anchor types of stirrer
This type stirrer mostly used in crystallization process .This type of stirrer bladed are very close to wall of reactor , so we can get good heat transfer . but this is suitable for low RPM application. The main advantage of anchor type of stirrer is it gives good heat transfer rate. It also required more power for agitation. Main disadvantage of anchor type of agitator is it gives more stirrer touchable volume.
Propeller type
Propeller type agitator can use in GLR , it can use for corrosive material.
Which type of agitator used in glass lined reactor ?
You can use anchor type of agitator for reactor (Glass lined ) , also you can use paddle type of stirrer for reactor (Glass lined reactor ).
Conclusion
Article clearly give basic information about stirrer and its types . There are paddle type , anchor type , turbine type and other types of stirrer available. It also clear how to select suitable agitator as per process requirement. Hope you like this article . Please do share and comment in comment section .
