Summary:碩士 === 國立臺北科技大學 === 機電整合研究所 === 96 === This study aims at exploring a laboratory-made micro-fog condensing system and micro-fog impactor which applies the benefits of vibrating foggy effect onto separation of particles. This work also discusses how to process a better separation way in order to get sub-micro or nanoscaled particles. The experiment uses ball-milled ZnO powders as the test sample. This separation mechanism is achieved through the formation of fog created using ultrasonic vibrator. With the aid of fanning and pump, the fog will pass through into impactor, used inertia of particles to separate micro-fog. The ultrasonic atomization is proven to be able to separate micron and nanoscaled particle from aqua. The smallest particle size is 68nm from the experiment and the tendency of separation was the same with little particles inertia. They most influenced with the efficiency of separation in the impactor that changing the entrance of flow velocity and the jet flow diameter by the experiment.
