<P>PROBLEM TO BE SOLVED: To provide a carbon dioxide feeder to horticultural facilities, supplying carbon dioxide, using almost no electric power in the daytime, by collecting/concentrating carbon dioxide from flue gas, using a physical adsorption method requiring no heat source when collecting carbon dioxide in flue gas, storing concentrated carbon dioxide, and rapidly ejecting stored carbon dioxide when a carbon dioxide concentration in a greenhouse decreases. <P>SOLUTION: This carbon dioxide feeder to horticultural facilities includes a means of bringing nitrogen oxides and sulphur oxides in flue gas, generating in a carbon dioxide supply source to equal to or lower than a concentration affecting no plant growth, a means of collecting/concentrating carbon dioxide contained in flue gas, using a carbon dioxide absorbent for adsorption and desorption by pressure swing, a means of storing concentrated carbon dioxide by pressure equal to or higher than atmospheric pressure, and a means of rapidly ejecting carbon dioxide stored in the carbon dioxide absorbent to horticultural facilities. <P>COPYRIGHT: (C)2012,JPO&INPIT |
