Abstract


Air distribution simulation testing is an effective method of the electrostatic precipitator airflow evenly distributed . Used to guide the design of industrial ESP simulation results , in terms of time in the economic and working conditions than in the industrial ESP directly test and adjustments to be far superior , so this method is widely used at home and abroad . Due to the complexity of the flow field inside the ESP , this problem can not theoretically solve the accuracy and use of various formulas are not satisfactory , computational fluid dynamics (CFD) in the case of complex flow conditions is not easy to obtain a better solution . With the similarity theory , the use of model experiments to predict the airflow moving in the electrostatic precipitator is the most reliable method . Measuring instruments can only be some point in the flow field is measured , it is difficult to provide overall information flow field , these information is urgently needed to study of electrostatic precipitator airflow organizations . PIV (Particle Image Velocimetry) the emergence of the first flow field velocity distribution time audience measurement , and a high degree of accuracy . Model experiments in this paper successfully applied to the PIV the electrostatic precipitator airflow organizations , get some meaningful data to obtain satisfactory results . This paper mainly reflected in the work of innovation : ( 1 ) using similarity theory , self ESP performance simulation experiment station , and the use of clean water instead of flue gas to do a simulation of the airflow within the electrostatic precipitator ; (2 ) by a specific experiment describes the use of the PIV and PIV technique to measure the flow field within the three conditions ESP ESP internal liquidity situation , provides an internal flow field for the study of ESP technical means for the ESP collection efficiency of air distribution device to provide an experimental basis ; (3) analysis of airflow round hole layout defects , homemade square hole airflow cloth board used in the experiments , PIV the measurement results are shown conducive to a uniform distribution of the gas stream , to obtain a satisfactory effect .
