摘要
由于垃圾成分复杂及垃圾收运量季节波动,现有垃圾焚烧厂脱酸塔污染物出口设定值的确定主要依赖于运行人员经验,导致运行困难及调控存在较大的不确定性.建立脱酸塔动态调整模型,基于该SO2排放逐月分配额量、垃圾入场量预测值及当前运行参数,动态调整脱酸塔PID控制逻辑中的出口SO2浓度设定参数,实现总排放量的控制及脱酸塔经济效益增加.该模型建立温度-过量系数分区控制石灰浆量,节约石灰浆液32 941 L/h,吨蒸汽对应石灰浆消耗量较正常运行减少4.31 L/t,较正常运行节约7.46%的石灰,脱酸效率提高约1.48%.
Abstract
Due to the complex composition of garbage and seasonal fluctuations in garbage collection and transportation volume,the determination of pollutant outlet values for existing garbage incineration plants mainly relies on the experience of operating personnel,resulting in operational difficulties and significant uncertainty in regulation.A dynamic adjustment model is established for the deacidification tower,based on the monthly allocation of SO2 emissions,predicted garbage inflow,and current operating parameters,and it dynamically adjusts the outlet SO2 concentration setting parameters in the PID control logic of the deacidification tower to achieve control of total emissions and increase the economic benefits of the deacidification tower.This model establishes temperature excess coefficient zoning to control the amount of lime slurry,saving 32 941 L/h of lime slurry.The consumption of lime slurry corresponding to one ton of steam is reduced by 4.31 L/t compared to normal operation,saving 7.46%of lime and increasing the deacidification efficiency by about 1.48%.
