<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for gas purification capable of reliably collecting particulate material in gas and capable of improving the efficiency of gas purification by improving removal performance of harmful gas such as desulfurization. <P>SOLUTION: In an exhaust gas flow path 22 of a casing 21, a discharge electrode 25 capable of producing an ion wind that induces and forms a secondary flow to a direction of crossing the flow of exhaust gas by applying a prescribed voltage is disposed, on the other hand, a dust-collection electrode 26 having a prescribed aperture through which the ion wind is allowed to pass is disposed on an inner wall surface of the casing 21, and an absorbing liquid supply device 31 comprising a plurality of liquid supply nozzles 32 which supply an alkali absorbing liquid of absorbing a harmful component to the dust-collection electrode 26 and form a liquid film on the surface is disposed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
