This study aims to minimize the energy consumption of the disc-stack centrifuge by optimizing the factors that affect its consumption using response surface methodology. Eight factors with the potential to affect the energy consumption of the centrifuge were identified. A 3k factorial Box-Behnken design was used as the design model to investigate the chosen factors using Minitab software. The result indicates that the main three factors that have the largest impact on the energy consumption of the centrifuge are the particle size, the rotational speed, and the outer radius of the centrifuge, respectively. Moreover, the results demonstrate that the energy consumption of the centrifuge can be reduced from 1 kWh/m3 to 0.1 kWh/m3 achieving a 90% reduction in total. In order to achieve such a low consumption, the outer radius and the rotational speed of the disc-stack centrifuge should be designed to not exceed 0.175 m and 3000 rpm, respectively.

这项研究旨在通过使用响应面方法优化影响碟片式离心机能耗的因素,从而最大程度地减少碟片式离心机的能耗。确定了八个有可能影响离心机能耗的因素。使用3 k因子Box-Behnken设计作为设计模型,以使用Minitab软件调查所选因素。结果表明,对离心机能耗影响最大的三个主要因素分别是离心机的粒径,转速和外径。此外,结果表明,离心机的能耗可以从1 kWh / m 3降低到0.1 kWh / m 3总共减少了90%。为了实现如此低的消耗,碟片式离心机的外径和转速应分别设计为不超过0.175 m和3000 rpm。
