DEODORIZING APPARATUS INSTALLED TO AIR DUCTS

摘要

PURPOSE: A deodorizing device installed in air ducts does not require extra power source, leading to decrease in carbon dioxide emission to make a more environmentally friendly environment, and the compact scale of the facility causes no limit on installation. CONSTITUTION: A deodorizing device installed in air ducts (1a) comprises: an exhaust duct (10a) for discharging polluted air generated in odor generating sources such as waste water, livestock wastewater, excrements and disposal plant of food scraps; an exhaust fan (50a) in the exhaust duct for exhausting air including odor material, an impeller (20a) for rotating by the air flowing due to the exhaust fan; an atomizer (30a) for spraying chlorine dioxide inside the vortex formed by the impeller; a chlorine dioxide feeder (80) for supplying chlorine dioxide to the atomizer; a measurement sensor of chlorine dioxide concentration (95a) for measuring the concentration of the chlorine dioxide included in the air ejected through the exhaust duct; and a control unit (90) coupled to the measurement sensor of chlorine dioxide concentration for controlling the sensor to control the generation rate of chlorine dioxide.
