ADSORPTION RECOVERY APPARATUS

PROBLEM TO BE SOLVED: To provide an adsorption recovery apparatus excellent in energy efficiency and the recovery efficiency of an organic solvent by utilizing the residual heat of an adsorbent. SOLUTION: The adsorption recovery apparatus comprises: a plurality of adsorption towers having the adsorbent which continuously adsorbs the organic solvent and desorbs the adsorbed organic solvent in treated gas, alternately; a blower line that transfers the treated gas containing the organic solvent to the adsorption towers through a transferring pipe with a blower; a desorption means that transfers carrier gas to the adsorption towers and heats the adsorbent to desorb the organic solvent from the adsorbent; an air-cooling line that cools the adsorbent with gas after desorbing the organic solvent from the adsorbent; and a recovery line that concentrates, separates, and recovers the organic solvent after desorbed, and transfers the carrier gas that has passed through the adsorption towers to the transferring pipe. After the blowing of the carrier gas and desorption means are suspended, the apparatus blows the gas to the adsorbent from the opposite side to the blowing direction of the treated gas, and then blows the gas discharged from the adsorption towers to the transferring pipe.
