Stainless steel stirred tanks to require the aid of a crystallizer when used. The advantages and disadvantages of this type of crystallizer are different.
Stainless steel stirred tank crystallizer has advantages and disadvantages. Let's introduce the stainless steel stirring tank from these two aspects.
Advantages of stainless steel stirred tank crystallizer: The structure is simple, the operation is easy, the adaptability is also good, and many crystallization processes can use such equipment.
Stainless steel stirred tank crystallizer:
1. Such tanks are generally small and can only be produced intermittently, so the production capacity is small. If the tank is too large, it will not only be difficult to manufacture, but also the mixing of the radial and axial directions will not be uniform.
2. It is difficult to finely adjust and control the crystallization process with such equipment, for example, to adjust the crystal growth rate, control the crystal size, etc.
The bleed port is used to vent the gas during charging or other necessity. This crystallizing tank is usually made of stainless steel, which requires a smooth inner surface, a crystal that is not easily adhered to the wall and is easy to clean and sterilize. The new stainless steel stirred tank crystallizer is actually a stirred tank reactor, but the agitation structure has changed to accommodate solids in the tank. The stirring shaft of the crystallizer is equipped with two stirrings, the middle one stirs the liquid, and the bottom stirring stirs up the precipitated crystals. There is a jacket on the outside for heat exchange inside and outside the tank. It usually has a PH and temperature measuring probe. The discharge port is below. The manhole on the stainless steel mixing tank is used as a feeding port. It is also used for cleaning and overhauling.
