莱钢炼钢厂节能降耗及资源综合利用的措施

Measures of Energy-saving and Resources Comprehensive Utilization in the Steelmaking Plant of Laiwu Steel

莱钢炼钢厂对转炉钢渣进行粗选、破碎,实现了分类综合利用,并开发了转炉冶炼前期喷溅渣循环利用技术,含铁固体废弃物资源返回率100%;加大烟尘治理,降低了烟气排放浓度,烟(粉)尘排放量平均每月在60t以下;实施水的串级循环利用及转炉除尘污水药剂处理,实现了工业废水的"零"排放;加大转炉烟气的回收利用,提高能源利用率。实现了经济效益、社会效益、环境效益的和谐统一。

The Steelmaking Plant of Laiwu Steel adopted a series of energy-saving and resources comprehensive utilization measures and realized harmonious unity of economic benefit, social benefit and environmental benefit. These measures are as follows： achieving classification utilization by roughing, crushing and developing recycling technology of splashing slag in converter initial smelting period, the utilization rate of solid waste contained iron reached 100%; increasing flue dust control and reducing flue gas emission concentration, flue dust （power） output emission concentration is reduced to 60 tons per mouth; actualizing water cascade recycling and reagent treatment of converter dedusting wastewater, realizing zero-emissions of industrial wastewater; increasing the recovery and utilization of converter gas for improving energy utilization ratio.
