Title:
脱硝装置における触媒再強化処理方法およびその方法に使用する強化剤液スプレー装置
Document Type and Number:
Japanese Patent JP4795526
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a highly economical catalyst restrengthening treatment method in a denitration apparatus. SOLUTION: A part 12 to be strengthened of a catalyst 9 is strengthened again by impregnating it with a strengthening agent liquid; thus, not only the part 12 to be strengthened but also the catalyst 9 can be prevented from being degraded and abraded. Since a required denitration performance can be obtained by a catalyst 9 already set up though an operation to impregnate the part 12 to be strengthened with a strengthening agent liquid is necessary, this method is highly economical in comparison with the case when a degraded and abraded catalyst 9 is required to be replaced by a new catalyst 9.
