MULTIPLE AUTOMATIC AIR CLEANER

摘要

An air filtering device is provided to make an air current equally penetrate through the front side of an air filtering unit and to clean an electric dust collecting unit equally and repeatedly by plural water cleaning lines. An air filtering device is composed of a plasma discharge unit(30) which is installed adjacently to at least one inflow port(13) of a duct(10), applies an electric charge by applying high voltage and decomposes gaseous pollutants by using corona pulse discharge; an electric dust collecting unit(40) installed at the rear side of the plasma discharge unit to collect the charged dust; a water cleaning unit formed at the lower side of the electric dust collecting unit to clean the collected dust; an ultraviolet photocatalyst unit(50) formed at the rear side of the electric dust collecting unit to remove the gaseous pollutants by oxidation; and a turbulence preventing net(15) provided with plural holes and installed between at least one inflow port of the duct and the plasma discharge unit to prevent turbulence generated when air currents flowing from at least one inflow port of the duct interfere with each other.
