EXHAUST GAS PURIFICATION SYSTEM AND OZONE GENERATOR

摘要

An exhaust purifying system includes a selective reduction catalyst provided on an exhaust passage of an engine, a fluid supply device for supplying a urea fluid to a section of the exhaust passage that is upstream of the selective reduction catalyst, a gas separator for separating source gas into oxygen-enriched gas and nitrogen-enriched gas, an ozone generator that includes an ozone producing space, to which the oxygen-enriched gas is introduced, and produces ozone from the introduced oxygen-enriched gas, an ozone supplier for supplying ozone to a section of the exhaust passage that is upstream of the selective reduction catalyst, a vortex tube for separating the nitrogen-enriched gas into cool air and warm air and discharging the cool air and the warm air, and a cooling device for cooling the ozone producing space by applying the cool air discharged from the vortex tube to the ozone generator.
