“…But the influence of high frequency electric coagulation; if ignoring a dust particle inertia, electric coagulation coefficient and alternating electric field frequency independent. [10][11][12][13][14][15] Chengqi Mao of the Dalian Maritime University, the experimental results in 2007 show that the alternating electric field of the coagulation efficiency is higher than that of Constant electric field and when electric field frequency is 40Hz, the effect is the best. Electric coagulation effect of the particle size increased about 21%, after the pre-charge facility is installed, the total dust removal efficiency of 2.6-3.5%.…”

Fine dust in the atmosphere is one of the key factors causing air pollution as well as fog and haze. Due to the limited efficiency of fine dust collection in conventional dust removal technology, pre-charged dust coagulation between particles to increase the effective collecting diameter, is an effective way to improve the dust collection efficiency. Currently, coagulation technology research falls into three mainly aspects: electric coagulation technology in constant electric field, alternating electric field and pulsed electric fields. The advantages and disadvantages as well as the research status and trends are fully analyzed in this paper, of which the technology that uses alternating or pulsed power supply for pre-charge device has more advantages and efficiency in coagulation. They will improve the efficiency of electric coagulation in further on the improved airflow pole with form and structure and the technical development of alternating or pulsed powers, which will make the coagulation and filtration technologies and new composite technology an important development direction of fine dust governance.

“…The charged aerosol was found to have 1e-3e charges per particle and it was concluded that small electric charges have a negligible effect on the coagulation rate. Xiang and Colbeck (1993) conducted coagulation experiments on charged, monodisperse aerosol in an enclosed chamber using a differential mobility analyzer (DMA) to measure particle charge and a condensation nucleus counter to measure particle concentration. Compared to uncharged particles, unipolar particles were found to have suppressed coagulation rates and symmetrical, bipolar particles were found to have higher coagulation rates.…”
