Dry capturing device for carbon dioxide

摘要

PURPOSE: A dry type carbon dioxide collecting apparatus is provided to improve the collecting efficiency of carbon dioxide by preventing the reverse flow of gas to a vertical transferring pipe using a bubbling fluidized-bed collector. CONSTITUTION: A dry type carbon dioxide collecting apparatus includes a collecting reactor(101), a vertical transferring pipe(108), a regenerating reactor(124), a first separator(112), and a second separator(120). The collecting reactor includes a collecting buffering chamber(102) and a collecting diffusing plate(104). A part of a space formed on the upper side of the collecting diffusing plate is filled with absorbent particles(138). One end part of the vertical transferring pipe is in connection with the collecting reactor. Another end part of the vertical transferring pipe is in connection with the first separator. The first separator collects carbon dioxide based on the absorbent particles and separates and discharges remaining gas. The regenerating reactor includes a regenerating buffering chamber(126) and a regenerating diffusing plate(128). A part of a spaced formed on the regenerating diffusing plate is filled with absorbent particles. Absorbent particles separated from the first separator are supplied to the regenerating reactor. The second separator separates and discharges carbon dioxide separated from the regenerating reactor.
