丝网除沫器分离性能实验研究

摘要

丝网除沫器广泛应用于石油、化工以及天然气等行业，丝网除沫器有缠绕式以及多层式两种结构，目前对于丝网除沫器的研究十分有限，且绝大部分是研究多层式结构，对于缠绕式结构的研究几乎没有报道。通过研究不同规格的缠绕式丝网除沫器的分离效率得到一系列实验数据，分析了丝网除沫器的结构参数以及气速对分离效率的影响。最后建立了的分离效率数学模型，其计算结果与实验结果有较好一致性。

Abstract：

Wire-Mesh mist eliminators are widely used in petroleum, chemical and gas industries. Wire-Mesh mist eliminators are divided into two kinds:spiral wound and layered structure. Literature on wire mesh mist eliminators is still fewer, and majority of research have reported on layered structure and little on spiral wound structure. In this work, a set of experimental data was obtained by investigating the separation capacity of different spiral wound wire mesh eliminators, the effects of gas velocity and design characteristics on the droplet separation efficiency were analyzed. Finally, a mathematic model is proposed. A good agreement was obtained between the experimentally measured values and the model predictions.

Keywords： wire-mesh mist eliminator； spiral wound； separation efficiency； mathematic mode
