摘　　要：由于煤泥粒度细,干燥后气固分离过程中,不可避免会出现大量灰尘,必须对灰尘进行捕捉和分离;同时由于采用火力干燥,排放尾气必须经脱硫处理,才能保证尾气排放符合国家环保规定,因此除尘脱硫系统起着至关重要的作用。依据除尘脱硫系统在国内外的研究现状,研制出了一种新型湿式脱硫除尘器。该除尘器采用湿式石灰石-石膏脱硫工艺脱硫,其脱硫基本原理为烟气所含SO2与生石灰浆液混合、反应、中和。工业应用表明:该除尘器结构简单,成本低,脱硫除尘效率较高,运行稳定,除尘效率达到97.8%,脱硫效率达到89%,设备阻力小于1 100 Pa,满足了烟尘排放标准,达到了干燥后气体的环保排放要求。Fine slime inevitably led to a great deal of dust during separation of solid and liquefaction,so it was necessary to capture the dust.Desulfuration was also essential in order to comply with the state laws of environmental protection.Based on the technologies at home and abroad,a new type wet desulfurization dust collector was developed. The wet limestone-gypsum desulfurization process was adopted.The working principle of the collector was that,the SO2 in the dust reacted with quick lime slurry.The industrial application showed that,the collector met the requirements of dust emission standards,with the advantages of simple structure,low cost,high efficiency and stable operation.The dust removal efficiency,desulfurization efficiency could reach 97. 8% and 89%,the equipment resistance was less than1 100 Pa.
