A New Type of Gas Wave Refrigeration Technology

针对传统气波制冷机体积大,冷凝积液排出困难等问题,本文提出一种新型旋转式突扩连通气波制冷机,并对其结构形式、工作原理和性能进行介绍。建立了室内实验测试流程,研究了射流频率、膨胀比、出口压力和振荡管长度对突扩连通气波制冷机制冷性能的影响规律。实验结果表明:旋转式突扩连通气波制冷机制冷效率比传统气波制冷机效率提高15%以上;装置不受振荡管长度制约,可有效减小传统气波制冷机体积。由于装置效率高,降低能耗,提高地层压力能的利用率,在天然气集输处理领域具有较好的应用前景。

In allusion to the disadvantages of traditional Gas Wave Refrigerator that the equipment is very large and the condensed liquid is hard to be discharged from the oscillating tube, this paper in-troduces Rotary Gas Wave Refrigerator with closed-ended connection oscillating tube. The structure of the closed-ended connection oscillating tube, working mechanism and performance evaluation are formulated, and the experiment workflow is constructed. Furthermore, the effect of jet frequency, expansion ratio, outlet pressure and the length of the oscillating tube on properties of Gas Wave Refrigerator is investigated. The experimental results show that the efficiency of Rotary Gas Wave Refrigerator with closed-ended connection oscillating tube increased by more than 15% than traditional Gas Wave Refrigerator, and the length of the oscillating tube has little affect on the performance of Gas Wave Refrigerator. So this structure can reduce the size of traditional Gas Wave Refrigerator effectively. The device has a good application prospect in natural gas because of its high efficiency and lower energy consumption.
