摘要
从往复式、转子式、螺杆式和涡旋式膨胀机的几何结构出发 ,对其膨胀过程进行了理论分析 ,并研究了各自的运动规律。通过对带有不同类型膨胀机的CO2 跨临界系统进行热力计算 ,得出了各种膨胀机的实际功率范围和特征结构尺寸。考虑到超临界二氧化碳的膨胀特性 ,提出了理想的CO2
From the viewpoint of geometric structure of reciprocating, rotary, scroll, and screw expander, CO 2 expansion process and their movement characteristics were analyzed respectively. On the basis of thermodynamic calculation for CO 2 transcritical system with different expander, the actual recover power and structural size are obtained. Considering the expansion behavior of supercritical CO 2, the general requirements of ideal expander are put forward and the pros and cons of different type of expanders are also compared.
