HYBRID AIR PURIFICATION APPARATUS FOR SIMULTANEOUS REMOVAL OF GASEOUS POLLUTANTS SUCH AS NOx AND PARTICULATE POLLUTANTS USING CATALYST-COATED FILTER

摘要

PURPOSE: A hybrid air purification apparatus is provided to simultaneously remove gaseous pollutants such as NOx and particulate pollutants from flue gas by using catalyst-coated filter. CONSTITUTION: The apparatus comprises a clean gas chamber(20) consisting of a cleaning system part and a clean gas outlet part(21), a dust collection chamber(7) where many dust collection filters(19) consisting of a catalyst coated filter, installed vertically down on a perforated plate(22) installed on the lower part of the clean gas chamber, an inner case part(15) separating air current flown in a tangential direction, an inflow duct part(12) where flue gas gone through a desulfurization process and reducing agents sprayed from a reducing agent sprayer are flown in a tangential direction and a hopper(8) primarily collecting dusts of the flue gas flown in a tangential direction by using centrifugal force and discharging the collected dusts.
