Traditional centrifugal extractor refer to early extraction equipment. With the development of technology and the continuous expansion of the application scope of centrifugal extractors, the performance requirements of centrifugal extractors are getting higher and higher. The problems of traditional centrifugal extractors have gradually emerged.
Main Problems Of Traditional Centrifugal Extractor
- The structure of traditional centrifugal extractors: The previous equipment was sealed at the bottom, which was prone to leakage and corrosion, and the bearings were easily damaged, which caused maintenance troubles, increased costs, and greatly shortened the service life of the equipment.
- Equipment material: The early centrifugal extractor was not made of corrosion-resistant materials, but the extraction systems were mostly strong acid and strong alkali systems, and ordinary stainless steel materials were easily corroded; titanium materials would also be corroded, and the corrosion rate of titanium materials would be significantly accelerated under the operation of the equipment; although the use of Hastelloy alloy can avoid some corrosion, the material is expensive and the equipment cost is too high.
- Traditional centrifugal extractor technology is not suitable for easily emulsified systems. For example, in traditional annular gap centrifugal extractors, the liquid between the rotating cylinder and the fixed cylinder will produce "Taylor vortex", and these rotating liquids that form "Taylor vortex" will be mixed again by the stirring paddle before entering the drum, which will eventually lead to excessive liquid mixing intensity, resulting in problems such as difficulty in separating the two phases or serious emulsification.
The above is an introduction to the problems of traditional centrifugal extractors. With the development of technology, the new CWL-M series centrifugal extractors developed and produced by Zhengzhou Tiei Extraction Technology have shown performance advantages.
Performance Characteristics of CWL-M Centrifugal Extractor
- The equipment structure has been improved, and a single-point structure with an upper suspension is adopted. There is no bottom bearing and mechanical seal in the processing area, and there is no risk of leakage. This solves the problem of frequent failures and short service life of the centrifugal extractor, and saves equipment maintenance costs.
- In addition to the original material selection, the equipment material can also be made of perfluorinated polymer materials, which can resist corrosion from strong acids (hydrochloric acid, mixed acids, etc.).
- The equipment has good mixing and separation effects, and a variety of mixing structures can be selected, with high separation effect, and can be applied to systems that are easy to emulsify.
CWL-M centrifugal extractor is an innovative improvement on the traditional centrifugal extractor, which solves and improves the original problems. For specific equipment details, welcome act us!
