高风速复合式电收尘器的试验研究

An experimental study on high wind speed compound electorstatic precipitators(HWSCESP)

应用"高风速"理论,将流体力学、电动力学、静电学有机结合设计出的高风速复合式电收尘器(HW SCESP)系统。试验以收尘效率作为收尘指标,以粉尘初始浓度、有效收尘面积、工作电压和系统风速为影响因素进行试验分析。结果表明,当粉尘初始浓度在45 g/m3,工作电压在47 kV,有效收尘面积为14.5 m2,系统风速为3.8 m/s时,收尘效率可达99.92%。从实验结果表明,HW SCESP是高效率、低成本的新型电收尘器。

According to the ＂high wind speed＂ theory,the HWSCESP system combines the hydrodynamics, electro dynamics and static electrics. The experiment was carried on with the dust collection efficiency as the index, with initial density of dust, working voltage as the influencing factors, examining the law of influence on the dust collection efficiency of every factor separately. The results indicate that when the dust initial density is about 45 g/m^3, and when working voltage is 47 kV, the effective dust collection area is 14.5 m^2 and the system wind speed is 3.8 m/s,the dust collection efficiency is up to 99.92. %. From this, it is indicated that HWSCESP is the new dust collection device with high efficiency and low cost.
