<p>A discharge type exhaust emission control system characterized by comprising at least one discharge unit (74) consisting of a tubular outer electrode (7), a tubular dielectric (28) of heat-resistance, high-strength ceramics being inserted into the tubular outer electrode (7) and having an outer circumferential surface forming a tubular gap (51) with respect to the inner circumferential surface of the tubular outer electrode (7), and an inner electrode (52) facing the tubular outer electrode (7) while touching the inner circumferential surface of the tubular dielectric (28) held between, and a power supply (3) for applying a discharge voltage between the outer and inner electrodes (7, 52) under a state where exhaust gas is flowing through the tubular gap (51).</p> |
