AFTERTREATMENT SYSTEM WITH SOLID AMMONIUM FOR SELECTIVE CATALYST REDUCTION

摘要

The present invention relates to an exhaust gas reduction device using solid ammonium for a selective catalyst reduction device and, more specifically, relates to an exhaust gas reduction device using solid ammonium for a selective catalyst reduction device which makes ammonia by pyrolyzing solid ammonium and allowing the ammonia to react with nitrogen oxide on a selective reduction catalyst to purify the ammonium into nitrogen harmless to the human body; enables a reduction of nitrogen oxide even in an initial start of a vehicle by rapidly increasing a temperature of solid ammonium to a temperature where the solid ammonium is sublimated into ammonia gas through pyrolysis using microwaves; and easily controls an amount of sublimation and speed of the solid ammonium into ammonia gas by heating the solid ammonium using microwaves. The exhaust gas reduction device using solid ammonium for a selective catalyst reduction device comprises: a high-frequency generating device which generates microwaves; an inner container connected to the high-frequency generating device; and solid ammonium received in an inner container containing polarized media wherein the polarized media can be heated by the microwaves.
