Abstract
- In this paper, a wire-plate electrostatic precipitator with expanded-contracted plates(ESP-ECP) was proposed. A numerical method was adopted to investigate the influences of different arrangements of ECP on the electric field intensity, airflow field, particle trajectory and collection efficiency under different voltages, inlet gas velocities and particle sizes. Furthermore, it was compared with the traditional ESP with parallel plates(ESP-PP). The results indicated that the ECP expands the surface area of the collecting electrode, and effectively enhances the electric field intensity near the collecting electrode. With the increase of the ECP height, the electric field intensity and influence range increase. The low-velocity vortices generated by the ECP help to prolong the retention time of particles, which is conducive to particle removal. In general, the collection efficiency of the ESP-ECP is superior to the ESP-PP. [ABSTRACT FROM AUTHOR]
