| 摘 要： | 旋转式压力交换器是利用正位移原理工作的流体能量回收装置。介绍了设计的流体自驱型旋转式压力能交换器．应用在SWRO系统中，进行了实际工况条件下的能量回收试验、端面密封性能试验和流体掺混试验。除流体掺混试验用1．8％和3．5％浓度的NaCl溶液做试验介质外，其余试验均用自来水做试验介质。试验结果表明，压力能交换器内部端面密封性能对压力水平有关键影响，在现有装置条件下，转子转速超过1000r／min，高压端进流压力1．25MPa，能量回收效率达到76％，流体掺混率低于5％。

| Abstract: | Rotary pressure exchanger(RPE) is a kind of energy recovery equipment based on the principle of positive-displacement.A fluid-driven rotary pressure exchanger was designed and tested in a real SWRO system.Experiments on fluid energy recovery,face-seal characteristics and fluids mixing were carried out.Water was used as fluid in all experiments except 1.8% and 3.5%NaCl solutions in mixing experiment.Results showed that the performance of face-seal had great effect on energy recovery.With RPE,the pressure was... |
