Investigation On The Effect Of Electrode Structure On Atomization During Electrostatic Atomization

In the new century,air pollution has become increasingly serious,frequent haze weather,PM2.5 and other fine particles seriously threaten the survival and development of mankind.Among them,power,steel,and other industries in the industrial production of waste gas emissions is the most important source of particulate matter pollution.As a widely used dust removal equipment in the industrial field,electrostatic precipitator has a high removal efficiency for large particles of solid dust,but its removal effect for fine particulate dust and gaseous pollutants（NO_X,SO_X,NH₃,etc.）is not good,and there is little research on the coordinated treatment of gas-solid waste of HPS.The results show that the high voltage electrostatic atomization technology has a significant effect on the collection and removal of fine dust and gaseous pollutants.Articles,which is based on high voltage electrostatic atomization technology,waste gas in the following two collaborative processing of anti-pollution idea,imagine the existing local modification,electrostatic precipitator to filter the internal electrode to replace original thorn vertical line,using the hollow cavity instead of the thorn,and openings in the surface of the hollow cavity,weld metal electrode cavity,and replace the bur with metal electrode cavity,liquid injection cycle in the hollow cavity,to join the wet factor,and broaden the category of the pollution treatment,improve the efficiency of the pollution treatment.In this study,the design and selection of reasonable cavity electrode structure to achieve the ideal atomization effect is the key to the success of wet electrostatic dust removal.This paper uses the laboratory environment instead of the dust collector environment,and takes the cavity electrode structure as the entry point,the selection of the different length of straight single cavity electrode（13 mm,8 mm,4 mm,2 mm）,different separation angles of double cavity electrode（0°,30°,45°,60°,75°）and deviate from the electrodes,up and down in the 10kV,15 kV,20 kV,25 kV and 30 kV five kinds of typical high voltage electrostatic atomization experiment,using the PCO.dimax high-speed cameras on the electrode electrostatic atomization process in Image acquisition,Image-Pro Plus Image analysis to analyze the late imaging and data processing software,from the discharge characteristics of the metal cavity,In this paper,the characteristics of various cavity electrodes were studied from the aspects of the Taylor conical appearance,spray efficiency,atomization cycle time distribution,liquid consumption.The final result shows that all kinds of cavity electrode increase with the increase of applied voltage,discharge current,under the same voltage separation Angle 60°double cavity electrode discharge current is higher than other electrodes,showing good electric property;At the same time,the spray efficiency of the electrode in the atomization process and the ratio of the atomization separation stage to the atomization period were higher than that of other double-cavity electrodes and other types of electrodes,and the liquid consumption was in line with the expected level,showing a good atomization effect.In conclusion,this electrode has better electrical characteristics and atomization effect than other electrodes and can be used and popularized as an optimized electrode.At the same time,a series of electrostatic atomization experiment results show that at 15kV applied voltage,the spray efficiency of droplets in the atomization process of each electrode and the ratio of atomization separation stage to atomization period can reach the maximum value of this electrode.Therefore,this voltage can be used as the optimization voltage to promote.
