The gas, liquid, and dust particle behavior inside a centrifugal wet scrubber was simulated and a submodel for predicting its collection efficiency was developed that also takes in account the reduction in collection efficiency due to droplet carryover. Centrifugal wet scrubbers are used in many industries and deliver a high scrubbing efficiency at relatively low capital and operational costs. However, they often experience problems such as droplet carryover at high gas flows and reduced collection efficiency at low gas flows. An improved understanding of flow processes inside the scrubbers is needed to develop a better scrubber design. An experimental test facility was setup for this purpose which also served to validate the CFD modeling results. Ideal operating parameters for maximum scrubbing efficiency and minimum droplet carryover were identified. © 2017 American Institute of Chemical Engineers AIChE J, 2017

离心式湿式除尘器除尘效率的数值预测

模拟了离心式湿式洗涤器内部的气体，液体和灰尘颗粒行为，并开发了一个用于预测其收集效率的子模型，该模型还考虑了由于液滴残留而导致的收集效率降低。离心式湿式洗涤器用于许多行业，并且以相对较低的投资和运营成本提供了较高的洗涤效率。但是，它们经常遇到诸如在高气流下带走液滴并在低气流下降低收集效率的问题。为了开发更好的洗涤器设计，需要对洗涤器内部的流动过程有更好的了解。为此设置了一个实验测试设施，该设施还用于验证CFD建模结果。确定了用于最大洗涤效率和最小液滴残留的理想操作参数。©2017美国化学工程师学会AIChE的Ĵ，2017年
