Electrostatic precipitators（ESP） with the improved new tape of double vortexes plates were designed to solve the problems of low removal efficiency of super-fine dust of ESP and lack of design parameters. A row of electrode was added in front of each row of the plates and plates were optimized. The flow field of ESP was simulated by FLUENT of ANSYS14.0

and three kinds of factors of high of plates（H）

distance of each row of plates（d）

and particle size（dp） were set. Simulation results show that this new ESP can compensate the shortages in the past that the electric field strength is weak in the parks of region for the distance between the electrodes and plates is too large; a double vortex flow can be formed in the region of plates when H is 14 mm and d is 110 mm. The highest wind speed can reach 8.8 m/s in the plate slit

the wind speed can reach 0.5 m/s near the plate and the pressure loss is about 260 Pa when speed is 3 m/s; Particle residence time can increase by about three times. Integrity and scientific are remarkably improved by the effect of electric field. It is showed that the performance advantages of new ESP

are obvious

and this new ESP provides the corresponding parameters and basis for the design of research and industrial application.
