Abstract:
1. A continuous concentration system for volatile organic compounds for concentrating volatile organic compounds that undergo an absorption process and a removal process, the continuous concentration system comprising: a moving-bed chamber in which modules for absorbing volatile organic compounds are contained, wherein an absorption bed line to which the volatile organic compounds are supplied to be absorbed to the module is provided on one side of the moving-bed chamber, and a removal-cooling bed line for performing a removal process for removing the volatile organic compounds absorbed to the module and a cooling process for cooling the module that has undergone the removal process is provided on the other side of the moving-bed chamber, wherein the absorption and removal processes are continuously performed by the module moved while circulating the absorption bed line and the removal-cooling bed line, a blower supplies the volatile organic compounds to the absorption bed line, a removal blower supplies carrier gas to the removal-cooling bed line to remove the volatile organic compounds absorbed into the module, removal gas concentrated and removed by the carrier gas in the removal-cooling bed line is sent to a condenser, the volatile organic compounds are condensed to organic solvent by refrigerant circulated to a cooling tower and is recovered to an organic solvent recovering tank, and after the carrier gas in the condenser is re-circulated and supplied to a heat exchanger and is heated, it is circulated by the removal blower again.
