【Abstract】 The way and theory to improve the potential of dust collection of cathode in the elec- trostatic precipitator was investigated.Collecting mechanism of escaping particles was studied. Based on the theories,the new-type cathode is designed and made and it has the multi-function of collecting dust,minishing the lost of second blowing dust,weakening and overcoming the back corona.Discharging characteristics was studied through experiments on the laboratory.Two-dimen- sional flow field mathematics model in electrostatic precipitator was set up,and synchronously con- firm boundary and initial conditions.Solve two-dimensional flow field mathematics model and study the air flow situation using two dimensions k-εequation with adding the windproof device or without the device.更多还原
