褐煤制浆和配煤制浆技术

基于中国煤炭资源状况及褐煤难成浆的特点,提出采用配煤制浆的方法来提高制浆浓度。分析了国内外褐煤和配煤制浆技术的研究现状,同时介绍了国内褐煤制浆技术的发展。研究发现:现有的配煤技术多采用煤质较好的原煤和褐煤,应寻求更多的现有资源和褐煤配煤制浆来提高煤浆浓度,尤其是热值不低却未被充分利用的煤炭资源,如煤炭液化废渣、沥青等,以充分利用煤炭资源,保护环境。 Based on China coal resource and poor slurrying property of lignite,provide that the coal water mixture concentration could be increased by making blending coal with lignite,then preparing coal water mixture with blending coal.Analyse the technologies of coal water mixture with lignite and blending coal at home and abroad.Introduce the development of these technologies at home.The results show that the existing coal blending technologies always use raw coal or lignite with better quality.In the future,more existing resources and lignite should be used to prepare coal water mixture in order to improve its concentration
