摘要
煤泥是煤矿开采生产过程中排出的煤粉,其形成是在选煤厂洗选加工过程中的副产品,其特点容易结块影响运输,且对空气污染有一定的危害.利用旋转式蓄热氧化装置通过对煤矿瓦斯抽采泵站中的低浓度瓦斯的利用,与乏风或空气掺混后产生高温烟气,通过热风换热装置进行煤泥烘干,处理后的煤泥水分含量可以从25％～28％降到12％左右,对煤矿瓦斯利用和煤矿生产具有客观的积极意义,同时提高了能源的综合利用.
Abstract
Coal slime is pulverized coal discharged in the process of coal mining,and its formation is a by-product in the washing and processing process of coal preparation plants.It is easy to agglomerate af-fecting transportation,and has certain harm to air pollution.The rotary regenerative oxidation device uti-lizes low-concentration gas from the coal mine methane drainage pumping station,which is mixed with ventilation air methane(VAM)or air to produce high-temperature flue gas.This high-temperature gas is then used to dry the slime through a hot air heat exchange device.The moisture content of the treated slime can be reduced from 25％～28％to about 12％.This process has objective positive significance for the utilization of coal mine methane and the production of coal mines,and it also improves the compre-hensive utilization of energy.
