The impact of the disc spacing on the performance of the disc centrifuge is mainly reflected in the separation efficiency. The disc centrifuge is an efficient solid-liquid or liquid-liquid separation equipment. The drum is equipped with a set of disc-shaped parts that are stacked on each other, that is, discs. There is a small gap between the discs. . This design significantly increases the settling area and shortens the settling distance required for particles, thereby improving separation performance.
1. Appropriate spacing between discs:
When the spacing between discs is appropriate, the flow and concentration distribution at the inlet and outlet of the gap between each layer of discs is relatively uniform. In this case, the separation efficiency of the disc centrifuge is the best, and it can effectively separate solid particles or droplets from liquid.
2. The spacing between the discs is too large:
When the spacing between the discs is too large, the separation efficiency may be reduced.
The reason is that the large spacing between the discs may cause the particles to be disturbed by the liquid flow during the sedimentation process, making it difficult to effectively settle on the discs.
3. The spacing between the discs is too small:
When the spacing between the discs is too small, it may also be unfavorable for separation.
The reason is that the small spacing between the discs may increase the resistance of the liquid flow, affect the uniformity and stability of the liquid flow, and then affect the sedimentation effect of the particles.
Considerations in practical applications
In practical applications, the selection of disc spacing needs to be determined based on the specific separation materials, separation requirements, and the model and structure of the disc centrifuge. Through methods such as experiments and numerical simulations, the disc spacing can be optimized to improve the separation efficiency and performance of the disc centrifuge.
