<p>A cold heat recovering type apparatus for cooling by-product gases is provided to minimize energy consumed in cooling of the by-product gases while separately removing moisture contained in the by-product gases as condensation water by cooling the by-product gases. An apparatus for cooling by-product gases comprises: a rotating regenerative medium(20) which performs a heat exchange process while the by-product gases pass through the rotating regenerative medium, and which is rotatably installed about a rotating shaft(21); and a cooler(30) for cooling the by-product gases to condense and remove moisture contained in the by-product gases, wherein a flow of the by-product gases is set such that by-product gases with high temperatures flown in from respective processes of an ironworks pass through a first zone set in the rotating regenerative medium, by-product gases passing through the first zone of the rotating regenerative medium pass through the cooler, and by-product gases with low temperatures passing through the cooler pass through a second zone set in the rotating regenerative medium. The first and second zones are encircled and sealed by regenerative medium housings(22,26) respectively. The rotating regenerative medium and the regenerative medium housings have sealing members(23,27) inserted therebetween, and the sealing members are slidingly contacted with the rotating regenerative medium by the rotation of the rotating regenerative medium.</p> |
