<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment apparatus and an exhaust gas treatment method by means of which a specific constituent such as an environmental pollutant contained in exhaust gas is removed at a high removal rate without complicating equipment and processes and largely increasing power. <P>SOLUTION: The exhaust gas treatment apparatus includes: a treatment tank 10 for storing an absorbing liquid 20; an exhaust gas distribution tube 30 for ejecting the exhaust gas into the absorbing liquid 20 and forming in a part above an exhaust gas ejection depth position a froth layer 25 where the air bubbles of the exhaust gas and the absorbing liquid 20 come in gas-liquid contact with each other; an absorbing liquid replenishing tube 40 for replenishing the absorbing liquid from the outside of the treatment tank 10 to a part below the froth layer 25 in the treatment tank 10; a stirrer 32 for stirring the absorbing liquid 20 positioned below the froth layer 25 and generating the flow of the absorbing liquid toward the froth layer 25; and an absorbing liquid supply part 50 for directly supplying the absorbing liquid to the upper part of the froth layer 25. The absorbing liquid and the exhaust gas come in gas-liquid contact with each other in the froth layer 25, so that sulfurous acid gas is removed from the exhaust gas. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
