<p>PURPOSE:To obtain a device for purifying air by providing the device with a dehumidifying bed and a contaminated gas adsorbing bed in a chamber to separate particularly CO2 gas in air with a simple constitution. CONSTITUTION:The contaminated gas is sucked to the inside of a fan 5 and forcibly fed to a contaminated gas adsorption column 1 composed of the cylinder shaped chamber 4 having an inlet 2 and outlet 3. A distributor 6, the dehumidifying bed 7 and the adsorbing bed for adsorbing CO2, NOx and SOx particularly CO2 are installed from the upstream side along a flow passage in this order. As a result, the contaminated air is fed to the dehumidifying bed 7 to remove moisture to be in an adequate drying state, and next, passes through the adsorbing bed 8 to mainly adsorb and separate CO2 and is purified.</p> |
