SLAG HEAT RECOVERING DEVICE, SLAG HEAT RECOVERING METHOD, AND HEAT GENERATING METHOD
PROBLEM TO BE SOLVED: To provide a device for recovering heat as high-temperature water from high-temperature slag generated in refining metal.SOLUTION: A slag heat recovering device 250 is composed of a charging portion 22 for high-temperature slag 21, a water tank portion 23 for reserving water, a slag discharging portion 210, and a heat exchanging portion 25. The charging portion 22 is inclined, the discharging portion 210 has a screw conveyor 29, and the heat exchanging portion 25 is disposed at an upper part in the vertical direction, of the water tank portion 23. The high-temperature slag 21 has a temperature of 800°C or more, and its grain size is 2-8 mm. The charging portion 22 has an inclined face of an inclination angle of 20-55 degrees. The high-temperature slag 21 is charged into water along the inclined face, the slag 28 after cooling is discharged, and steam 24 generated in charging the slag 21 into the water is recovered and made to exchange heat with water 27C to obtain hot water 27.
【課題】金属製錬の際に発生する高温スラグから高温水として熱回収を行う装置を提供する。【解決手段】スラグ熱回収装置２５０は、高温スラグ２１の投入部２２、水を溜めておく水槽部２３、スラグの排出部２１０、熱交換部２５から構成され、投入部２２は傾斜しており、排出部２１０にはスクリューコンベア２９を有し、熱交換部２５は水槽部２３の鉛直方向上方に設ける。高温スラグ２１は８００℃以上の温度を有し、粒度２〜８ｍｍ、また投入部２２は傾斜角２０〜５５度の斜面を有する。高温スラグ２１を斜面に沿って水中に投入し、冷却後のスラグ２８を排出し、水中へのスラグ２１投入により発生した蒸気２４を回収し、水２７Ｃと熱交換させることで温水２７を得る。【選択図】図２
