可调式超音速分离器旋流段的研究分析

Research and Analysis of Swirler of Adjustable Supersonic Separator

超音速分离器一种高效、节能、低成本的新型天然气脱水净化装置,该技术是基于天然气在拉瓦尔喷管内绝热膨胀降温,然后经分离翼旋流,以分离天然气中的气相水和重烃组分。分离翼是分离器的关键部位,其在旋流段的位置会对分离器内部流场产生重要影响。本文提出一种新的可调式旋流管设计,并利用数值模拟软件(FLUENT)模拟分离器内部的流动,对比3种不同位置分离器对超音速分离器内压力、温度、速度的影响,以便优化分离器设计,提高分离效率。

The Supersonic separator was a kind of high efficiency, energy saving, low cost of new natural gas dehydration equipment. The technology based on the natural gas adiabatic expansion cooling in Laval nozzle and the separation wing made the fluid like cyclone. The purpose was to separate the gas phase water and heavy hydrocarbon component in natural gas. The separation wing was a key part of the separator, the position of the wing in the cyclone separator section also had a significant influence on the internal flow field. In this paper, a new design of adjustable swirler was presented. With the help of the software FLUET, the different flow parameters of internal flow field were obtained, and compared the effect of three kinds of different position separator on the pressure, temperature and velocity of the supersonic separator in order to optimize the design of the separator and improve the separation efficiency.
