Document Type and Number:
WIPO Patent Application WO/2023/229193
Kind Code:
A1
Abstract:
The present invention relates to a carbon dioxide removal device, which can remove carbon dioxide under an internal-air condition without introducing external air and has a relatively long lifespan, the device comprising: a case including an inlet end in through which air flows and an outlet end through which the air is discharged; a filter for filtering out pollutants in the air flowing into the case; an inflow part allowing the air to flow into the case; an adsorbent positioned at the rear end of the inflow part so as to adsorb carbon dioxide in the influent air, thereby reducing the concentration of carbon dioxide; an energy supply means provided at the rear end of the inflow part so as to supply energy to the adsorbent and desorb carbon dioxide adsorbed by the adsorbent, thereby regenerating carbon dioxide; an outlet end opening/closing door provided at the outlet end or a flow path connected to the outlet end, so as to open/close the outlet end; and a control part, which controls the inflow part, the energy supply means and the outlet end opening/closing door so as to operate the carbon dioxide removal device in any one mode from among a carbon dioxide removal mode, a carbon dioxide regeneration mode and an off-mode.
