提出了一种全新的湿气再循环超音速分离管工作原理和结构设计,该装置可循环地将天然气中的重质烷烃和水分离出来;其主要优点包括结构紧凑,无化学污染,节能环保,从而能够提高分离效率。内置旋流器的旋流特性和阻力特性对超音速分离管的工作性能有重要直接影响。目前设计加工了一套再循环超音速分离管,并搭建了室内实验台,分别对采用内置旋流器A型和B型对再循环超音速分离管的脱水性能进行了实验研究,目的在于寻找流动阻力小,旋流强度高,分离效率好的内置旋流器设计。实验结果表明:内置旋流器A型具有较强的旋流特性,B型具有较强的阻力特性。采用内置旋流器A型的分离管分离效率高,脱水性能好,因此得出内置旋流器的旋流特性相比阻力特性对分离管的脱水性能的影响更大,内置的旋流特性越好,超音速分离管的脱水效果越好。

Experimental study for the effect of the built-in cyclone configuration on the dehydration performance of the new wet-gas recycling supersonic separator

This paper firstly in detail presents the operating principle and structural design of the new wet-gas recycling supersonic separator. This device can be used to separate hydration and liquid form natural gas without using chemicals, and there are some benefits including compact structure, small floor space, no chemical pollution and high separating efficiency. Owing to the swirl characteristics and resistance characteristics of cyclone have the important impact on the dehydration performance of wet-gas recycling supersonic separator, two experimental rigs individual with built-in cyclone A and B were constructed and systematic dehydration performance experimental investigations of rigs were carried out. To find the better cyclone design with small flow resistance, high swirl strength, high separation efficiency. The experimental results showed that cyclone A has better swirl characteristics, and cyclone B has better resistance characteristics. The recycling separator with cyclone A has the higher separation efficiency and better dehydration performance, so comparing with the resistance characteristics, the swirl characteristics has the greater impact on the dehydration performance of the recycling separator. The better swirl characteristics of the cyclone, the better dehydration performance of the recycling separator.
