脱硫吸收塔浆液品质恶化原因分析

Analysis on Causes of the Slurry Quality Deterioration in Desulfurization Absorption Towe

吸收塔浆液被污染、品质恶化发生在浆液反应池中,浆液起泡溢流、浆液"中毒"和石膏浆液脱水困难是其3种表现形式。分析了导致吸收塔浆液品质恶化的内外因素,灰尘浓度超标、工艺水水质差等外部因素是浆液品质恶化主要原因。提出了浆液品质恶化的预防措施和处理原则。运行中只要及时发现、准确判断、处理方法得当,可保证烟气脱硫系统的安全、稳定运行。

Absorber slurry polluting and quality deteriorating occurs in the slurry reactor pond with three performances ： slurry foaming and overflowing, slurry ＂poisoning＂ and difficulty in gypsum slurry dewatering. This essay analyzes internal and external factors which cause slurry quality deterioration in absorber, main causes of which are external factors such as boiler ignition and startup, fuel oil combustion, dust concentrations exceeding standard etc. And also precautions and principle of solution are put forward in this es- say.
