<P>PROBLEM TO BE SOLVED: To provide an exhaust gas treatment method which can perform the suppression of worsening of treated gas properties and prevention of flushing, keeping down the running cost by reducing the amount of a medium used, preventing the increase in pressure loss in a reaction chamber, keeping down the maintenance cost by preventing corrosion of a recovery hopper, stabilizing operation by improving extraction of the medium from the recovery hopper, and size reduction of the reaction chamber. <P>SOLUTION: A first recovery hopper 25 which recovers the medium P discharged out of a first reaction chamber 5a on the upstream side in the flow direction of an exhaust gas W and a second recovery hopper 26 which recovers the medium P discharged out of a second reaction chamber 5c on the downstream side are installed, each independently. Thereby, a bypass flow flowing from the first reaction chamber 5a to the second reaction chamber 5c is eliminated, and the inflow of the exhaust gas from the first reaction chamber 5a to the first recovery hopper 25 is decreased. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
