Abstract
The purpose of this work is to develop a new type of particle collection filter using electrical dischargetechnology. The new filter must be high efficiency and applicable to air conditioner to use for household, sowe suggested the new type filter. The new type filter has a distinctive feature except characteristic of ESP,a thickness of collecting electrodes is thicker than that of existing type ESP. When particles come into thefilter, the particles will collide with side surfaces of the collecting electrodes. At the same time of particlecollision with side surface, the particles are charged by the collision and collected by electrical force.Therefore, we called this type "Ion Impactor". We optimized condition of thickness of collecting electrodesand applied voltage using six sigma method because thickness of collecting electrodes and applied voltageare very important to improve the collection efficiency. We analyzed distribution of electric field line, theelectric field lines were uniformly distributed on the side surface of the collecting electrodes. From thisanalysis, we can see the improvement of the particle collection efficiency. We made the ion impactor typefilter on a large scale to equip to the air conditioner, and measured the particle collection efficiency. For the0.1∼0.2㎛ range particle, the collection efficiency was higher than that of existing type ESP by 30%. Thecollection efficiency of the 0.3∼0.4㎛ range particle was higher by 12%.
