燕子山矿选煤厂煤泥干燥系统升级与改造

Upgrading and modification of coal slurry drying system in Yanzishan Mine Coal Processing Plant

针对燕子山矿选煤厂煤泥干燥系统所排放的烟尘及二氧化硫等参数超标的问题,提出了治理方案,对湿式除尘器进行了升级改造,且在系统末端增设了脱硫塔、湿式静电除尘器等设备,并通过该方案的实施,完成了煤泥干燥系统的升级改造,最终使得烟气的烟尘及二氧化硫的排放浓度达到了环保标准。

Aiming at the problem that the parameters of soot and sulfur dioxide emitted from the coal slurry drying system of Yanzishan Mine exceeding the standard,a treatment plan was proposed to upgrade the wet dust collector,and additional equipment such as desulfurization tower and wet electrostatic precipitator were installed at the end of the system,and through the implementation of this plan,the upgrading of the coal slurry drying system was completed,which finally made the concentration of soot and sulfur dioxide emission from the flue gas finally achieved the environmental protection standard.
