The future development trend of centrifuge
Centrifuge industry now ushered in the development of the golden period, but if you can in this development trend can always remain in the forefront of development, you need to seize the initiative, to have "people have my gifted" spirit, but also need a clear The development planning objectives, can not rest on its laurels, we must break through innovation!
According to professional personnel analysis, the future development trend of the centrifuge will be to strengthen the separation performance, develop large-scale centrifuge, improve the slagging mechanism, increase the dedicated and combined drum centrifuge, strengthen the separation theory research and study the centrifugal separation process optimization control Technology and so on.
Strengthen the separation performance, including to improve the drum speed; in the centrifugal separation process to add a new impetus; speed up the slag speed; increase the length of the drum to centrifugal sedimentation separation time and so on. The development of large-scale centrifugal centrifuge, mainly to increase the drum diameter and the use of double-sided drum to improve the processing capacity of the processing unit volume of equipment investment, energy consumption and maintenance costs reduced. Theoretical research, the main study of the fluid flow inside the drum and the formation mechanism of the residue, the study of the minimum separation and processing capacity of the calculation method.
Filter centrifuge and sedimentation centrifuge, mainly rely on to increase the drum diameter to expand the drum circumference on the face; separator in addition to drum peripheral wall, there are additional work surface, such as disc separator disc and room The inner cylinder of the separator significantly increases the settlement face.
In addition, the more difficult the separation of the solid particles in the suspension, the more difficult to remove the fine particles in the filtrate or separation solution. In this case, the centrifuge requires a higher separation factor to be effectively separated; the liquid in the suspension When the viscosity is large, the separation rate slows down; the density difference of the components of the suspension or emulsion is large, which is beneficial to the centrifugal sedimentation, while the suspension centrifugal filtration does not require the density difference of the components.
The choice of centrifuge shall be based on the size and concentration of solid particles in the suspension (or emulsion), the density difference between the solid and the liquid (or both liquids), the viscosity of the liquid, the characteristics of the residue (or sediment), and the requirements for separation Comprehensive analysis to meet the residue (sediment) moisture content and filtrate (separation liquid) clarity requirements, the initial choice of which type of centrifuge. And then according to the amount of processing and operation of the automation requirements to determine the type and specifications of the centrifuge, and finally verified by the actual test.
