AI Technical Summary

Technical Problem

Existing technologies suffer from low waste heat recovery efficiency of steel slag, high water consumption, and a tendency to generate secondary pollution.

Method used

Design a trough-type high-temperature molten steel slag waste heat utilization device, which integrates a horizontal trough, crushing components and radiant heat exchange components. The steel slag is crushed and heat is recovered through the reciprocating swing and rotation of the horizontal trough. Superheated steam is produced by a gas-liquid separator to avoid direct contact with water.

Benefits of technology

It achieves the effects of cooling, crushing and producing superheated steam from steel slag, simplifies the processing flow, saves water resources, reduces environmental protection costs, and avoids dust-laden steam generated by water quenching.
