Abstract Based on the convey flow field of charged particles determine the coagulation efficiency.The tentative system of charged coagulation is designed.The quantity of electricity of charged particles are investigated through experiment.And a flow field measurement technique PIV(Particle Image Velocimetry) system is adopted to study the additional electric field effect on particle flow.The experimental results shows that if charged voltage is under-10 kV,the charge-to-mass ratio increases with decreasing charged voltage,reaches a saturation value at-60 kV charged voltage.The velocity,vorticity of charged gas-solid flow increase with decreasing voltage,and turbulent kinetic energy reaches the maximum value at-50 kV.
