焦油渣、煤粉结球通过复合炉焦化用于制备电石原料

Tar Residue and Pulverized Coal Nodule are Used to Prepare Calcium Carbide Raw Materials by Compound Furnace Coking

生态环保部明确指示,焦化厂生成的煤焦油渣被视为危险废物,禁止直接排放。煤焦油渣是一种有害有毒的危险废物,处理不当易造成环境污染,且其还含有大量的固定碳和有机组分,具有较高的热值,如果能将之化害为利、变废为宝,对陕西北元集团锦源化工有限公司“节能降耗”工作具有重要意义。文章以焦油渣和煤粉为原料结成球,用于复合炉焦化后,作为电石制备的原料,实现煤焦油渣资源回收利用,降低公司炼焦生产成本和危废处理费用。

Ministry of Ecology and Environment the People’s Republic of China expressly stipulates that coal tar residues produced by coking plants are hazardous solid wastes and are not allowed to be dumped directly.Coal tar residue is a kind of harmful and toxic waste residue.Improper handling can easily cause environmental pollution,and it also contains a large amount of f ixed carbon and organic components,and has a high calorif ic value.If it can be turned into prof it and waste into It is of great signif icance to Shaanxi Beiyuan Group Jinyuan Chemical Corporation’s“energy saving and consumption reduction”work.In this paper,tar residue and pulverized coal are used as raw materials to form balls,which are used as raw materials for calcium carbide preparation after compound furnace coking to realize the recycling of coal tar residue resources and reduce the company’s coking production costs and hazardous waste treatment costs.
