摘要

摘要: 在模拟工况条件下,使用多功能试验除尘器、电称低压冲击系统(ELPI)等对PM₁₀、PM_2.5、PM_1.0等微细颗粒物和粉尘进行低低温电除尘技术的试验研究。结果表明:在低入口烟气温度下(67~68 ℃),试验除尘器对微细颗粒物和粉尘的脱除效率显著高于高入口烟气温度(86~89 ℃)。在低入口烟气温度下,降低入口风量,微细颗粒物和粉尘脱除效率提高的程度更为显著。因为入口风量降低后,电场风速更低,微细颗粒物和粉尘在电场的停留时间更长,更有利于低低温电除尘器对微细颗粒物和粉尘的捕集。

Abstract: Under simulated operating conditions, new multi-functional testing dust remover and electrical low pressure impactor (ELPI), etc. were used to conduct experiment study on the low-low temperature electrostatic precipitator (ESP) technology for the fine particle (such as PM₁₀, PM_2.5, PM_1.0) and dust. The results showed that PM₁₀, PM_2.5, PM_1.0 and dust removal efficiencies were significantly higher at lower inlet flue gas temperatures (67-68 ℃)than that at higher inlet flue gas temperatures (86-89 ℃). At lower inlet flue gas temperatures, as the inlet flue gas flow rate decreased, the extent of increased fine particle and dust removal efficiencies was more significant, which indicated that as inlet flue gas flow rate decreased, the residence time of fine dust in the electrical field extended, thus more convenient to collecting fine particle and dust for low-low ESP.
