Steel slag cracking and waste heat recovery system

The utility model relates to a steel slag cracking and waste heat recovery system which comprises a steel slag transportation and storage device and a steel slag cracking furnace, and a cold water pipe is wound on the furnace body from bottom to top, extends upwards to the furnace cover from the furnace body and is fixed on the inner wall of the furnace cover, so that water in the cold water pipeis heated from low temperature to high temperature. Cracking and waste heat recovery of the steel slag are realized; steel slag is fully cracked, steel slag waste heat recovery is achieved, and the energy-saving and environment-friendly purposes are achieved. 本实用新型涉及一种钢渣裂解及余热回收系统，包括钢渣运输存储装置和钢渣裂解炉；炉体由下至上缠绕有冷水管，冷水管再由炉体向上延伸至炉盖并固定在炉盖的内壁上，从而实现出冷水管内的水由低温加热至高温。实现了钢渣的裂解和余热回收；充分地裂解钢渣及实现钢渣余热回收，达到节能环保的目的。
