Document Type and Number:
Japanese Patent JP7053393
Kind Code:
B2
Abstract:
To provide a denitrification device and a denitration method where the clogging of a denitration catalyst caused by the adhesion of dust is prevented, the service life of the denitration catalyst can be prolonged and safety operation can be performed and to provide an exhaust gas treatment facility with the denitrification device and an exhaust gas treatment method.SOLUTION: A denitrification device 10 is installed in a flue 100 and provided with a denitration catalyst 40 by which nitrogen oxides in an exhaust gas flown in the flue 100 are reduced and decomposed to nitrogen and water. Denitration agent spray means 30 spraying a denitration agent into the exhaust gas and electric charge imparting means 20 imparting electric charge having the same polarity as the denitration catalyst 40 to dust in the exhaust gas are arranged at the front stage of the denitration catalyst 40.SELECTED DRAWING: Figure 2
