1. Daily maintenance of low-temperature catalysts For daily maintenance of low-temperature catalysts, attention should be paid to cleaning the catalysts and checking the various systems of the denitration equipment when the equipment is shut down. Since the operating temperature of the low-temperature denitration catalyst is relatively low, the ammonia spraying should be stopped for 1 hour before shutting down. The moisture and ammonia adsorbed on the catalyst should be thoroughly dried. At the same time, the ammonia spraying should be delayed when starting to completely dry the moisture. For denitration projects with online heating systems, the catalyst should be heated regularly according to the actual operating conditions to eliminate the excess moisture and ammonium bisulfate adsorbed on the catalyst. The heating temperature should be maintained at 300-350℃ for 24 hours. Whatsapp: 86 15854288924 #scrcatalyst #catalyst
