| At present,China has serious environmental pollution,dust removal equipment and environmentally friendly renewable solar energy sources have been widely used.Considering the current energy crisis and environmental issues,this paper uses the solar energy photovoltaic technology to combine a new-principle motor with electrostatic precipitator technology to design a solar electrostatic precipitator,and uses a high-voltage DC corona discharge device that generates ion wind to directly convert electrical energy into the kinetic energy of the air.Compared with the traditional motor,the energy conversion scheme of the new-principal motor mechanical device is more reasonable,the overall structure is simple,the layout is convenient,and what’s more the noise of mechanical vibration is eliminated.This article has carried on the corresponding research to the thrust and electric field performance of the new principle motor operation.Firstly,based on the Biefeld-Brown Effect,this paper analyzes the characteristics of corona discharge through experimental studies.The thrust value of the driving device under different voltage and electrode geometry parameters has been measured by experiments.Then the ionic wind phenomenon was used to explain the thrust principle of the device.Based on this,the formulas of thrust and thrust efficiency were derived using one-dimensional electrohydrodynamics method.Finally,the theoretical analysis results agree well with experimental values.It is concluded that the source of the thrust of the ion-driven device depends on the formation of the corona current and correlates with the magnitude of the corona current.When the voltage isn’ t too high,the thrust increases with the increase of the voltage,and it is roughly parabolic;it is inversely proportional to the distance between the electrodes;it is proportional to the length of the electrode;the magnitude of the thrust increases with the width of the aluminum foil electrode(that is,the vertical height)and gradually become saturated.In addition,the influence of the air parameters on the thrust force has been also analyzed,and it was found that lowering the air pressure was beneficial to increase the thrust of the wire-aluminum foil electrode device.In the simulation environment of MATLAB,the dissertation analyzes the potential,electric field intensity,space charge density and current density distribution of the dust removal device and calculates them.The experiments have shown that when the device is applied with a proper DC high voltage,thrust can be generated under a certain electrode structure and electric field distribution to perform rotation.By using high voltage,the resources are greatly saved,and the tedious use of a fan to drive the rotation of the equipment is eliminated,which has important research significance in the field of electrostatic dust removal. |
