DENITRATION OF NOX IN WASTE GAS AND WASTE GAS TREATMENT APPARATUS

摘要

PURPOSE:To perform safe treatment by spraying an aqueous solution having sodium azide dissolved therein from a spray device and charging electric energy in this spray to form plasma. CONSTITUTION:An aqueous azide solution is sent into a spray device 2 by a pump while NOx-containing waste gas is introduced into said spray device for the sake of spray. The flow rate of the aqueous azide solution and that of the NOx-containing waste gas are controlled so as to obtain such a state that the aqueous azide solution is sprayed uniformly and the high frequency power of plasma generating coils 3, 4 is charged to apply electric energy to the wet gas sprayed in a reaction chamber 5 to generate plasma. By this method, a byproduct can be inexpensively removed and the waste gas can be treated efficiently.
