Embodiment Construction

[0013] The exhaust gas adsorption system of the present invention sends the exhaust gas containing VOC components into the adsorption tower, the adsorption system optimizes the gas-liquid contact through countercurrent flow, and flows the adsorption solvent into the adsorption tower so that the VOC components in the exhaust gas are adsorbed . Transfer the adsorption solvent with adsorbed VOC components to a desorption tower so that the VOC components adsorbed to the adsorption solvent are desorbed by thermal energy and recovered in the regeneration process. As a result, an inert gas free of VOC components is released into the air.

[0014] For this purpose, the present invention provides an adsorption tower comprising adsorbing VOC components contained in exhaust gas by circulating the adsorption solvent and releasing VOC-free gas into the air; and separating VOC components from the adsorption solvent by circulating the carrier gas , And the exhaust gas adsorption system of th...

Abstract

The present invention relates to a vent gas adsorption system and a method of recovering volatile organic compounds (VOCs), more particularly to a vent gas adsorption system devised to effectively adsorb VOCs included in the vent gas and reduce VOC content of the vent gas, and a method of recovering VOCs.

Description

technical field [0001] The present invention relates to an exhaust gas adsorption system and a method for recovering volatile organic compounds (VOC), and more particularly to an exhaust gas adsorption system designed to efficiently adsorb VOC contained in exhaust gas and reduce the VOC content in exhaust gas , and the method for reclaiming VOC. Background technique [0002] Membrane separation systems, core cooling systems, adsorption systems, and combinations thereof are known as techniques for removing and recovering VOCs from exhaust gases. [0003] As for the adsorption system, Korean Patent Registration No. 266479 discloses a method of effectively removing VOCs by feeding polluted gas into an adsorption tower filled with silica gel and activated carbon. [0004] And, Korean Patent Registration No. 2002-10384 discloses a method and an apparatus for continuously circulating an adsorbent at a medium temperature by vacuum, and separating and recovering VOC contained in ex...
