摘要/Abstract

摘要： 基于DPM与拉格朗日液膜模型,建立了折线型折流板间隙内气液流动分析模型,通过试验数据验证了模型的准确性.研究了折流板运行参数对分离性能的影响规律,结果表明,在一定程度上,随着入口流速的增大,分离效率会逐渐增大;因此在气液分离设备运行期间,适当增大折流板入口流速可提高分离效率;但压降会随之增大,提高系统能耗.液滴尺寸小于130 μm时,随着液滴尺寸的增大,分离效率会缓慢减小;液滴尺寸大于130 μm时,随着液滴尺寸的增大,分离效率会逐渐增大;因此,在此叶片结构下的入口液滴尺寸可在合理范围内尽量增大以提高分离效率;总体而言,液滴尺寸对压降影响较小.可为气液分离设备运行优化提供理论依据.

Abstract: Based on the DPM and Lagrange liquid film model, a gas-liquid flow analysis model is established in the interspace of a polygonal deflector. The accuracy of the model is verified by experimental data. The influence of deflector operating parameters is studied on separation performance. The results show that the separation efficiency will gradually increase to a certain extent with the increase of the inlet flow rate. Therefore, during the operation of gas-liquid separation equipment, the separation efficiency can be improved by appropriately increasing the inlet flow rate. At the same time, the pressure drop will be increased, which will increase the energy consumption of the system. When the droplet size is less than 130 μm, the separation efficiency will slowly decrease with the increase of droplet size. While when the droplet size is greater than 130 μm, the separation efficiency will gradually increase with the increase of droplet size. Therefore, the inlet droplet size under this blade structure can be increased within a reasonable range to improve the separation efficiency. In general, the droplet size has little effect on the pressure drop, which can provide theoretical basis for the operation optimization of gas-liquid separation equipment.
