钢铁企业烟粉尘重点排放源分析
|
摘要
调研并核算了我国典型钢铁企业烧结、球团、炼焦、高炉炼铁、转炉炼钢、热轧、冷轧、自备电站和石灰窑等工序的烟粉尘年排放量及其占全厂的比例。分析了钢铁厂内烟粉尘排放的重点工序,以及各工序中的主要排放源。筛选出了钢铁企业的十大烟粉尘重点排放源,总计占全厂烟粉尘排放量的80.44%。并为钢铁企业的烟粉尘治理及排放监测提出了建议。
Smoke and dust annual emissions from sintering,pellet,coking,blast furnace,converter,hot rolling,cold rolling,captive power plant and lime kiln process in a typical iron and steel enterprise in China were accounted. The proportions of all dedusting system emissions in each process were calculated. The major process and pollution source of smoke and dust emissions were analyzed. Ten major smoke and dust emission sources in the whole factory were screened out,and the total proportion of the emission is 80. 44%. And then,some suggestions on smoke and dust control and monitoring were given.
