<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive exhaust gas cleaning method capable of reducing almost 100% of SO<SB>2</SB>in an exhaust gas, capable of still more reducing NOx, COx and dust particles and made small-sized enough to be capable of being mounted on a ship, and an apparatus therefor. <P>SOLUTION: An alkali liquid and an acidic liquid are formed by electrolyzing the sea and the exhaust gas to be treated is brought into contact with the acidic liquid and the alkali liquid in this order. The exhaust gas cleaning apparatus includes at least one gas-liquid contact means (1) for bringing the exhaust gas to be treated into contact with a treatment liquid and an electrolytic apparatus (16) for electrolyzing salt water to form the alkali liquid and the acidic liquid. At least one gas-liquid contact means (1) has an exhaust gas introducing port (5) on its upstream side and an exhaust gas discharge port (6) on its downstream side. At least one of gas-liquid contact means (3A and 3B) arranged in the apparatus is equipped with an acidic liquid spray means (4A) for spraying the acidic liquid or an alkali liquid spray means (4B) for spraying the alkali liquid. <P>COPYRIGHT: (C)2004,JPO</p> |
