选煤厂浮选尾煤资源化利用技术浅析
首发时间:2012-11-26
摘要:煤炭工业的快速发展以及煤炭入选量的急剧增大,使得尾煤产生量越来越大。合理开发尾煤资源对缓解我国能源危机以及控制因尾煤带来的环境污染具有重要意义。本文主要介绍了当前选煤厂浮选尾煤的特性和处理现状。分析了当前尾煤处理中燃烧、型煤加工、建材领域及填埋等处理方式的特点。比较了当前尾煤的处理方式得出,尾煤的利用从经济性和规模化出发,应以混燃技术为主,其他利用方式积极发展,使其呈现多元化发展路径。随着选煤工业的快速发展和节能环保的要求,尾煤的高效转化和清洁利用将是大势所趋。

Flotation tailings utilization of technical analysis
Abstract:The rapid development of the coal industry and the sharp increase of coal separation quantity have made tailings more and more. Reasonable development tail coal resources has important significance to relieve the energy crisis and control for tail coal brings pollution in our country. This paper mainly introduces the current characteristic of flotation tailings and the status quo of the treatment. Features of combustion, briqrette, building materials and landfill are analyzed. Compared the current tail coal processing mode, we should develop mixed combustion technology as a priority, and the other mode should be developed actively, and to make it present diversified development paths. With the rapid development of the coal preparation industry and requirements of energy efficiency and greenery, efficient transformation and the clean utilization will be the trend of the times.
