ABSTRACT:
A method for purification of exhaust gases, which consists of a first purification process comprising making a liquid alkaline chemical react on the exhaust gas thereby to recover nitrogen oxides contained in said exhaust gas as a precipitate together with said liquid chemical and a second purification process comprising passing said exhaust gas which has undergone the first purification process through a glass-fiber mat thereby to convert said glass-fiber mat into an electrode, making the noxious components of the exhaust gas remaining after the first purification process adhere to said electrode and, at the same time, jetting a liquid chemical capable of generating oxygen subject to thermal cracking into the exhaust gas thereby to increase the oxygen content of the exhaust gas, and an apparatus suitable for use in practicing said method.
