    摘要: Disclosed is a urea solution reformer and an exhaust gas purifier using the same, configured to heat a carrier gas supplied from a carrier gas source by a carrier gas heating unit (16), to inject the carrier gas heated by the carrier gas heating unit from a carrier gas injecting nozzle (17), and to cause a urea solution (18) to be supplied by a first urea solution supply nozzle (21) to a tip end of the carrier gas injecting nozzle so that the urea solution is atomized by the carrier gas injected from the carrier gas injecting nozzle. Provided to face toward the carrier gas injecting nozzle is a catalyst unit (23) for decomposing the atomized urea solution to reform it into an ammonia gas. Further provided is an ammonia gas supply nozzle (24) attached to an exhaust pipe (12) of an engine so as to supply the ammonia gas discharged from an outlet of the catalyst unit into the exhaust pipe. The urea solution is sufficiently atomized, and thus reformed into an ammonia gas by the catalyst unit with a good efficiency.

    摘要: A selective catalytic reduction catalyst capable of reducing the NOx in exhaust gas to N2 is arranged in an exhaust pipe of an engine. Fluid feed means has a fluid injecting nozzle facing the exhaust pipe on the exhaust gas upstream side from the selective catalytic reduction catalyst. The fluid feed means is configured such that a urea fluid that functions as a reducing agent is fed with the selective catalytic reduction catalyst from the fluid injecting nozzle to the exhaust pipe. Ozone feed means includes an ozone injecting nozzle that faces the exhaust pipe on the exhaust gas upstream side from the selective catalytic reduction catalyst, and on the exhaust gas upstream side or the exhaust gas downstream side from the fluid injecting nozzle. The ozone feed means is configured such that ozone is fed from the ozone injecting nozzle to the exhaust pipe.
