水泥矿山高硫夹层处理方法实践

摘要
D水泥厂大型石灰石矿面临100万t高硫夹层处理问题,并因此而造成水泥生产硫排放超标。文章详细介绍了该矿山高硫带分布情况,提出了几种可能的处理途径并分析其可行性,最终通过优化矿山矿石搭配、微改石灰石集中取料工艺,成功处理了问题,满足了政府环保部门二氧化硫在线监测<100 mg/m3的排放要求,节省了脱硫或排弃高硫料所需的高昂运行费用,同时也对自然资源做到了充分利用。
The large limestone mine of D cement plant is facing the problem of disposing 1 000 000 t of high sulfur interlayer,which causes the sulfur emission of cement production to exceed the standard.This paper introduces the distribution of high sulphur zone in the mine in detail,puts forward several possible treatment ways and analyses their feasibility.Finally,by optimizing the ore mix in the mine and modifying the centralized limestone feeding process,the problem has been successfully solved,which meets the requirement of on-line monitoring of sulphur dioxide emission by the government environmental protection department(<100 mg/m3),and saves the high operation cost of desulphurization or discarding high sulphur material.At the same time,it makes full use of natural resources.
