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%。
Using electric coagulation and electric bag composite dust collector experimental platform to study the coagulation and strengthening of the system under the total removal efficiency, zoning efficiency, fractional dust removal efficiency of fine particles and the electric field and bag filter area to capture dust particle size distribution changes . The results show that the coagulation efficiency and the total dust removal efficiency are enhanced in the electrical field of the electric bag dust collector. The electric field efficiency is increased by 5.38% and the total dust removal efficiency is increased by 0.03%. Especially for dust less than 5μm, Under the synergistic effect, the classification efficiency was improved by 5% -7% compared with that without electro coagulation. The voltage of condenser and the voltage of electric field have a great influence on the dust removal efficiency. The voltage of the condenser increases from ± 16 k V to 40 k V, the total dust removal efficiency increases from 99.76% to 99.96% When the voltage in the electric field increases from 25 kV to 65 kV, the total removal efficiency increases from 99.813% to 99.971%, the electric field efficiency increases from 21.73% to 70.17%, and the classification efficiency of 0-5μm dust increases from 20% to 30% To 55% to 65%.
