Abstract


The demisting efficiency of three structure demister and the influence of hook plate on the efficiency of demister were analyzed using fluent software. For a droplet with a particle size of 20μm, when α= 90°, L=20mm, and the inlet speed v=5m/s, the demisting efficiency of the wave plate demister has reached 96.67%. After installing the hook plate, the efficiency of the wave plate demister was significantly increased, the efficiency of the streamline plate demister was more than doubled, and The efficiency increase of the fold line plate demister was small. Finally, the comprehensive analysis showed that the wave plate demister had the highest efficiency and increasing the hook plate could increase the demisting efficiency but at the same time increased the pressure drop.
