<p>PURPOSE:To provide a method for treating waste gas and a device therefor in which a noxious material is effectively and at low cost removed or made harmless and the life of waste gas equipment is prolonged by a method using simple equipment. CONSTITUTION:Water (reduced water) whose ORP has been lowered by applying voltage is sprayed into waste gas, or the waste gas is passed through the reduced water housed in a screen tank dividing a waste gas duct, allowing a noxious material in the waste gas to be removed or made harmless. In order to perform this method, a water treating device (a reducing device) 4 for producing the reduced water fed to a spray nozzle 5 for spraying into the waste gas or to the screen tank is used. The reducing device is equipped with an applying electrode 6 forming a pair with an earth electrode, a DC power source, the 1st and 2nd high frequency switches, a high frequency switching command circuit, and a high frequency oscillator.</p> |
