Abstract

Electrostatic dust collector is a chamber that function to trap dust or particle. The operation is based on electrostatic precipitator(ESP) which is widely used in industry as an important equipment for environmental protection. Electrostatic dust collector is designed to be used as indoor air filter. In this project, principles of electrostatic precipitation such as particle charging, electric field strength and collection efficiency are reviewed. Particulate matter with dimension less than 2.5μm (PM 2.5) can penetrate deep into the human respiratory system. Air filter can help to remove airborne bacteria from operating room air to help prevent postoperative infection. ESP can also remove dusts and gaseous pollutants. These new advancements will widen the field of application of electrostatic precipitator. In this project, the electrostatic dust collector was developed in an acrylic box with a copper wire as a discharge electrode, placed between two plate collecting electrodes which is aluminium plate. The negative DC voltage was applied to the wire electrode. The factor that affected collection efficiency such as size of particle, type of dust and supply voltage will be discussed in this report.
