| 摘 要： | 为了使脱硫系统能以更经济、节能的方式运行,对烟气脱硫系统中吸收塔、浆液循环泵、气-气加热器(gas-gas heater,GGH)、增压风机、除雾器等重要设施的运行状况进行了分析,同时从脱硫剂耗量、电耗、水耗等方面对系统运行状况进行了详细的评价。认为:脱硫系统阻力主要源于吸收塔、GGH和烟道;系统电耗主要源于烟气系统、SO2吸收系统。提出了应提高液气比、控制装置入口SO2的质量浓度、吸收塔浆液pH值取5.4~5.6、增加GGH净烟气出口温度等优化运行建议。

| Abstract: | To enable more economical and energy-saving operation of flue gas desulphurization(FGD) system,the operation status of key equipment such as absorber,slurry recycle pump,gas-gas heater(GGH),booster fan and demister in FGD system is analyzed.The system's operation status is valued in detail from consumption of desulfurizer,power and water.It is concluded that the resistance of FGD system comes mainly from the absorber,GGH and flue,the systematic power consumption mostly from the flue gas system and the SO2 a... |
