APPARATUS FOR WASTE HEAT RECOVERY AND ABATEMENT OF WHITE PLUME OF EXHAUST GAS WITH REUSABLE OF WASTEWATER

摘要

The present invention relates to apparatus for waste heat recovery and abatement of white plume of exhaust gas with reusing wastewater by collecting hygroscopic salts while removing contaminants included in exhaust gas by filtering a solution containing hygroscopic salts and reducing white plume by collecting moist and latent heat included in exhaust gas by using the solution containing hygroscopic salts. The apparatus for waste heat recovery and abatement of white plume of exhaust gas with reusing wastewater comprises: a heat-moist exchanger for absorbing contaminants in exhaust gas while collecting latent heat and moist of exhaust gas by contacting exhaust gas with a solution of hygroscopic salts; a chemical bath of hygroscopic salts where hygroscopic salts which is in contact with exhaust gas flows; a first heat exchanger for heating exchanging water by heat exchanging the exchanging water and hygroscopic salts in the chemical bath; a filter for removing contaminants contained in the solution of hygroscopic salts in the chemical bath; and an enrichment water processing machine for separating raw water in a first processing water tank from enrichment water where the hygroscopic salts are enriched. The enrichment water separated by the enrichment water processing machine is provided for the chemical bath of hygroscopic salts.
