摘 要: | 为解决气液分离问题,提出了粒径可控离心分离的设想,即通过某种雾化技术产生粒径可控的液滴,然后根据液滴的粒径确定气液分离所需要的离心力,在高速旋转的叶片所产生的离心力作用下液滴一边与气流发生反应一边完成气液分离。为验证这一思想,搭建了一台旋流喷雾式单重态氧发生器(TFA-SOG),并通过计算流体力学模拟和实验对这台TFA-SOG进行了研究。研究结果表明,模拟的气液分离效率与实验的相一致,粒径可控离心分离的设想是可行的。

Abstract: | Gas-liquid separation is the key to the success of an aerosol-type singlet oxygen generator. To solve the problem of gas-liquid separation, the idea of droplet size-controlled centrifugal separation was proposed that size-controlled droplets are produced by using an atomization technique and then during the reaction of the droplets with gas flow the gas-liquid separation is simultaneously done by a centrifugal force which is determined by the sizes of the droplets and generated by a set of high-speed rotating blades. To verify this idea, a twisted flow aerosol singlet oxygen generator (TFA-SOG) based on this idea was built and investigated through simulation and experiment. The investigation shows that the simulated gas-liquid separation efficiencies are consistent with the experimental ones and the idea is feasible; the emphasis on further development of TFA-SOGs should be put on the droplet size-controlled atomization technique. |
