Apparatus and Method for Solid Recirculation in CO2 Capturing System Using Dry Sorbent and CO2 Capturing Sysgem including the Apparatus for Solid Recirculation

摘要

The present invention relates to a solid recycle apparatus for a dry carbon dioxide collecting apparatus, a control method thereof, and a dry carbon dioxide collecting apparatus having the solid recycle apparatus. And more particularly to a dry carbon dioxide capture apparatus having an absorption reactor, an absorption reactor cyclone, a regeneration reactor, and a regeneration reactor cyclone, which is provided at a side of a solid inlet pipe provided between the absorption reactor cyclone and the regeneration reactor, A solid circulation valve provided at one side of the solid inlet pipe to regulate the flow rate of the absorbent flowing into the regenerating reactor; And a gas injection pipe provided above the solid circulation valve for injecting and fluidizing a gas into a solid layer existing above the solid circulation valve, and a solid recycle apparatus for the dry carbon dioxide trapping apparatus.
