摘要
双塔双循环脱硫系统由于设备多、系统复杂而存在电耗物耗较高的问题。以某高硫煤火电厂双塔双循环脱硫系统作为研究对象,从物耗、能耗角度出发,研究了双塔双循环系统水平衡、石灰石供应系统、氧化空气系统、浆液循环泵组合运行等方面的优化,使其显示出较好的经济性。为其他高硫煤机组深度降低脱硫厂用电率方面提供经验借鉴。
Due to a large number of equipments and complicated system,the double-column double-cycle desulfurization system has the problem of high power consumption.This paper takes the double-column double-cycle desulfurization system of a high-sulfur coal-fired power plant as the research object,and studies the desulfurization from the perspective of material consumption and energy consumption.System optimization in the combination of water system,limestone supply system,oxidation fan and slurry circulation pump shows good economics.It provides experience for other high-sulfur coal units to reduce the power consumption of desulfurization plants.
