| 摘 要： | 提出了一种利用太阳能作为供热源同步进行海水淡化与热发电的新系统,并对系统原理进行了介绍。根据等熵均相平衡理论和两相流理论给出了两相流喷嘴的设计过程,分析得出了理论淡水率和发电量的计算方法。经理论分析得出,海水的焓降转化成系统的电能和海水的动能,因此应尽量减少海水那部分的动能来提高发电量。试验发现实际淡水率略高于理论值,而实际发电量较少。最后针对理论发电量和实际发电量的之间的差别给出了简单分析,其中海水未充分膨胀是发电量低的最主要原因。

| Abstract: | A new system combining desalination and power generation with soalr energy is presented and the principle of the new system is introduced.The design process on two phase nozzle is showd based on the Isentropic Homogenous Equilibrium theory and two-phase theory,and a caculated method on theoretic fresh water rate and generated energy is obtained.Through theoretical analysis,the enthalpy drop of brine is transformed into electric and kinetic energy,which should be reduced ultimately to increase generated ener... |
