Device and method for controlling ammonia escape in ammonia-based decarbonization system

A device for controlling ammonia escape in an ammonia-based desulfurization and decarbonization system, the device comprises:

• an ammonia-based desulfurization zone;
• an ammonia-based decarbonization zone;
• and
• an ammonia escape control zone,
• wherein:
• the ammonia-based desulfurization zone includes:
• a washing cooling section;
• an absorption circulating section;
• and
• a particle control section;
• the ammonia-based decarbonization zone includes:
• a cooling section;
• and
• an absorption circulating section;
• the ammonia escape control zone includes an ammonia escape control section that includes:
• an acidic ammonium sulfate solution washing system;
• and
• an acidic water washing system;
• the absorption circulating section of the ammonia-based desulfurization zone is connected to the acidic ammonium sulfate solution washing system of the ammonia escape control zone through pipes;
• and
• the particle control section of the ammonia-based desulfurization zone is connected to the acidic water washing system of the ammonia escape control zone through pipes.
