为提高吸收塔脱硫效率,开展燃煤焦化厂烟气脱硫吸收塔内过程优化及湿电除尘技术的研究.选择某燃煤焦化厂内2x1 000 MW机组作为研究对象,建立燃煤焦化厂烟气脱硫喷淋塔几何结构模型,从反应区容积、喷淋浆液速度、喷淋负荷等多个角度分析烟气脱硫吸收塔的脱硫效率,得到结论:设置一三层、一二三层喷淋方式,且喷淋浆液速度为9 m/s,喷淋负荷在100%~160%之间,可以使燃煤焦化厂烟气吸收塔脱硫效果达到最佳.在此基础上,按照烟气预处理、电场荷电、湿式收集、连续清灰、排放与监控等步骤,进行湿电除尘技术的应用,实践证明此项技术的应用不仅能够高效去除烟气中的粉尘颗粒,达到环保标准的要求,还能够降低能耗、提高焦化厂的运行稳定性.
Process Optimization and Wet Electrostatic Precipitator Technology Research on Flue Gas Desulfurization Absorption Tower in Coal-fired Power Plants
In order to improve the desulfurization efficiency of the absorption tower,research was conducted on the optimization of the internal process of the flue gas desulfurization absorption tower in coal-fired power plants and the wet electrostatic precipitator technology.Selecting a 2 x 1 000 MW unit in a coal-fired power plant as the research object,a geometric structure model of the flue gas desulfurization spray tower in a coal-fired power plant is established.The desulfurization efficiency of the flue gas desulfurization absorption tower is analyzed from multiple perspectives such as reaction zone volume,spray slurry velocity,and spray load.The conclusion is that setting a first three layer and first two three layer spray mode,with a spray slurry velocity of 9 m/s and a spray load between 100%and 160%,can achieve the best desulfurization effect of the flue gas absorption tower in a coal-fired power plant.On this basis,the application of wet electrostatic precipitator technology is carried out according to the steps of flue gas pretreatment,electric field charging,wet collection,continuous ash cleaning,emission and monitoring.Practice has shown that the application of this technology can not only efficiently remove dust particles in flue gas,meet environmental standards,but also reduce energy consumption and improve the stability of power plant opera tion.
