Abstract To improve the removal efficiency of flue gas fine particles in the desulfurization tower by wet desulfurization technology, a new set of purging electrically charged atomization nozzle device was designed and applied to the visual desulfurization tower model test bed. The effects of operating parameters on the particle removal efficiency were systematically investigated. The results show that the charge effect of spray droplets is greatly affected by spray flow rate and spray angle, and there is an optimal charge effect working condition value. With the increasing of particle size, the overall particle classification removal efficiency is increased. The particle removal efficiency is increased with the increasing of fluid flow rate and decreased with the increasing of flue gas flow rate, which is increased firstly with latter decreasing by increasing the dust concentration. The removal efficiency of particulate matter can be further improved after the droplet is charged, and the purpose of efficient removal of fine particulate matter can be realized.
