Abstract

PURPOSE: To make the construction of a waste gas treating apparatus simple, and improve waste gas treatment by conducting the waste gas successively to plural continuous discharge electric fields, and surely electrolytically dissociating and ionizing the components thereof.

CONSTITUTION: The wiper 10d of a switch 10 is connected to a contact 10a and high voltage is impressed across electrodes 2 and 3 by a power source 6. Spark discharge is caused across the electrodes 2 and 3 and the exhaust gas to be treated is conducted through a lead-in port 1a. The gas goes through spirally shaped passages 2a, 3a, 4a, 5a and exhausts from an exhaust port 1b while swirling in a cylinder 1. First, the gas flows out by forming swirling flow from the outside of the electrode 2 in the passage 2a, where the discharge points swirls and discharging takes place over the entire circumference. While it flows to the passage 3a, it is electrolytically dissociated and ionized. When the wiper 10d is changed over to a contact 10b, high voltage is impressed across the electrode 2 and 4, discharging takes place. When the wiper 10d is changed over to a contact 10c, discharging takes place across the electrodes 2 and 5. In this way, the waste gas is conducted to the three consecutive discharge electric fields. Whereby the respective components thereof are electrolytically dissociated and ionized.
