Controlling the Aerosol Contamination have many ways, one kind of which is electronics cleaning device which composed of high voltage and high frequency complex electric field. Because of its high efficiency saving energy, maintancing easily in the process of air cleaning handling,,it uses widely,.Now it uses widely more and more. But it is lack of research report and engineering parameter. In order to meet the requirement ,the author do some research about this.Firstly, analyzing enduring force of aerosol indoors,.analyzing the dynamics characteristic;Deducing the coagulation efficiency is because of dipoledomono effect between particles. Building the physical model of constraint coagulation, using Williams' way that he get the sound coagulation efficiency and gettingthe coagulation efficiency is in high frequencyfield.Secondly, Bsed on high voltage and high frequency complex field, the paper has built the laboratory station. Using particle counter KC-01 measures the concentration change. When aerosol indoors passes through the complexfield recycling, the paper fits the half time T_H drawing and coagulationefficiency K drawing of particle diamater ≥0.3μm> ≥0.5μm, ≥1.0μm on the condition of different elementary concentration,at the same time.the exchanging rate n is 20.Through the drawings we can get the time which the elementary concentration drops half and the coagulation efficiency K .But whenthe exchanging rate is n,we should revise the half time T_H and coagulation efficiency K, the revising efficiency is 20/n and n/20 respective.Finally, Bsed on high voltage and high frequency complex field adding filter, the paper has built the physical model of aerosol coagulation,theconcentration equation is In practical engineering.theequation and coagulation drawings will supply parameter for engineering design and equipment selection. It proved it's a feasible air cleaning project through testing in example. At the same time.through technical economy compare we draw a conclusion that this kind of air cleaning module is a economical, high-efficiency air cleaning project.
