摘要
概述了以工业废渣电石渣为原料,利用电石渣生产纳米碳酸钙、生石灰、氯化钙、晶须硫酸钙等化工产品的研究现状,指出了电石渣在化工领域资源化利用的发展方向及前景。建议继续加大电石渣资源化利用技术的开发,特别是电石渣生产氧化钙直接生产电石,以及电石渣生产氯化钙、纳米碳酸钙等高附加值精细化工产品;以资源化利用和循环经济的发展理念,加大技术研发力度、因地制宜,形成循环经济产业链。
The paper summarizes the research status of the productions of nano calcium carbonate,quicklime,calcium chloride,whisker calcium sulfate and other chemical products with industrial waste carbide slag as raw material,analyzes the development direction and prospect of the utilization of carbide slag in chemical industry,and puts forward the suggestion of speeding up the development of the utilization technology of carbide slag,especially the production of carbide by carbide slag,and the production of high added value fine chemical products such as calcium chloride and nano calcium carbonate from carbide slag.With the development concept of resource utilization and circular economy,we should increase the research and development of technology to form the industrial chain of circular economy.
