【摘要】：利用电凝并器及电袋复合除尘器综合实验平台,研究电凝并强化下系统总除尘效率、分区效率、微细粒子分级除尘效率和电场区及滤袋区捕集粉尘的粒径分布变化情况。结果表明,电凝并强化了电袋复合除尘器电场区除尘效率和总除尘效率,电场区效率增加了5.38%,总除尘效率提高了0.03%;特别对于5μm以下的粉尘,在电凝并器的协同作用下,分级效率较无电凝并器作用下提高了5%~7%。电凝并器工作电压和电场区电压对除尘效率影响较大,电凝并器电压由±16 k V提高到?40 k V,总除尘效率由99.76%增加到99.96%;电凝并强化下电场区电压由25 k V增加到65 k V时,总除尘效率由99.813%增加到99.971%,电场区效率由21.73%增加到70.17%,0~5μm粉尘的分级效率由20%~30%提高到55%~65%。
[Abstract]:Using the comprehensive experimental platform of electric condenser and electric bag composite dust collector, the total dust removal efficiency and partition efficiency of the system under electrocoagulation and strengthening are studied. The change of particle size distribution in the electric field and the filter bag area shows that the dust removal efficiency and the total dust removal efficiency in the electric field region of the electric bag composite precipitator are enhanced by electrocoagulation. The efficiency of electric field zone increased by 5.38 and the total dust removal efficiency increased by 0.03. Especially for dust below 5 渭 m, under the synergistic action of electric condenser, The working voltage and electric field voltage of the electric condenser have a great influence on the dust removal efficiency, and the voltage of the electric condenser increases from 卤16kV to? At 40 kV, the total dust removal efficiency increased from 99.76% to 99.96%, the total dust removal efficiency increased from 99.813% to 99.971when the electric field voltage increased from 25 kV to 65 kV, and the classification efficiency of the electric field area increased from 73% to 70.170 5 渭 m from 2030% to 5565V.
