<p><P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment method by which treatment efficiency of exhaust gas can be increased than hitherto by suppressing lowering of falling speed of an exhaust gas treating agent at an upper part of a fore-chamber, especially at an top end part of the fore-chamber and further treatment of the exhaust gas can be stably maintained. <P>SOLUTION: The exhaust gas treatment method is provided by which the exhaust gas treating agent is brought into contact with the exhaust gas while being moved downward from above in a treatment tank 15 where a plurality of chambers partitioned by vertically arranged porous plates 10, 11 are formed in a passing direction of the exhaust gas and then the exhaust gas treating agent is discharged from an lower part of the treatment tank 15. In this method, discharging speed V1 of the exhaust gas treating agent from the fore-chambers 12 in the treatment tank 15 formed at an entrance side of the exhaust gas by holding the porous plate 10 therebetween is set in accordance with a hole diameterϕof the porous plate 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
