Abstract: In order to improve the particle collection efficiency of the electrostatic precipitator ( ESP) ，the bipolar charged transverse-plate ESP is proposed． The collection performances of this bipolar charged transverse-plate ESP were compared with the ordinary ESP experimentally at room temperature and pressure． The sinter dust with 25. 405 m mass median diameter was used for the test particulate． The pressure loss of the bipolar charged transverse-plate ESP was about 30% higher than that of the ordinary one． The voltage current characteristics of the bipolar charged transverse-plate ESP was superior to the ordinary ESP． The collection efficiency of the bipolar charged transverse-plate ESP was also much greater than that of the ordinary ESP when the electric field in the range 2. 1 kV/cm to 3. 2 kV/cm and the velocity in the range 1. 0 m/ s to 1. 5 m/ s were set up respectively in this experiment．
