异极性荷电粒子磁电分级凝并建模分析
|
摘要
针对AC电场聚合器能耗大的问题,提出了一种凝并器结构——磁电分级凝并聚合器。聚合器前半段为永磁铁产生磁场,后半段为AC电场;减少AC电场长度为,增加了磁场凝并环节,进而减少了AC电场能耗。另外,建立粒子的荷电—磁电分级凝并数学模型,得出PM2.5粒子磁电分级凝并前后粒径变化关系表达式。仿真分析得出,磁电分级凝并前后粒子粒径增大2～6倍;凝并后的粒子粒径与粒子密度成负相关,与粒子质量浓度成正相关。
Aiming at the problem of large energy consumption of AC electric field aggregator, a condenser structure-magnetoelectric grading coagulation aggregator is proposed. The first half of the polymerizer generates a magnetic field for the permanent magnet, and the second half is the AC electric field. The reduction of the AC electric field length increases the magnetic field condensation and further reduces the AC electric field energy consumption. In addition, the charge-magnetoelectric grading and mathematical model of the particles was established, and the expression of the relationship between the particle size and the particle size of the PM2.5 particles was obtained. The simulation analysis shows that the particle size of the particles increases by 2 to 6 times before and after the magnetization is condensed. The particle size of the particles after condensation is negatively correlated with the particle density and positively correlated with the mass concentration of the particles.
