HIGHLY EFFICIENT GAS PROCESSING SYSTEM USING ELECTRIC DISCHARGE

摘要

PROBLEM TO BE SOLVED: To implement real-time processing depending on an operational state of an engine with inexpensive and durable structure, by performing processing in which NO is completely decomposed from NOx in exhaust gas by using electric discharge to generate NO2 required for oxidizing fine particles at a low temperature of 300 deg.C in a real time without influence of sulfur or the like in fuel, an particulate matters are completely decomposed by using ozone or active oxygen as oxidant simultaneously generating in the atmosphere of the NO2 and at the low temperature of about 300 deg.C and by using an inexpensive catalyst. SOLUTION: Of all Nox in the exhaust gas, the NO is completely decomposed by a bare discharge wire from and NO2 required for oxidizing fine particles at the low temperature of about 300 deg.C is generated in real time without the influence of the sulfur in the fuel, so that the processing is performed depending on the operational state of the engine. The particulate matters are completely decomposed by using the NO2 generated by the electric discharge and the ozone or activated oxygen simultaneously generated in the atmosphere of oxygen as oxidant at the low temperature of about 300 deg.C and by using he inexpensive catalyst.
