FLUE GAS AMMONIA REMOVAL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/262243
Kind Code:
A1
Abstract:
Disclosed is a flue gas ammonia removal method. In a boiler, nitrogen oxides in a flue gas to be treated as produced by the boiler are subjected to denitration treatment to obtain a denitrated flue gas containing ammonia gas and an acidic gas; the denitrated flue gas is drained to a deacidification tower and the acidic gas in the denitrated flue gas is subjected to deacidification treatment in the deacidification tower to obtain a deacidified flue gas containing solid dust and ammonia gas; the deacidified flue gas is drained to a bag-type dust remover, and the solid dust in the deacidified flue gas is subjected to dust removal treatment by means of the bag-type dust remover to obtain a dust removal flue gas containing ammonia gas; and the dust removal flue gas is drained to a deamination reactor, and the ammonia gas in the dust removal flue gas is subjected to deamination treatment in the deamination reactor to obtain a dischargeable flue gas.
