As one of the effective control devices of air pollutants, the wet electrostatic precipitator (ESP) is an effective technique to eliminate acid mist and fine particles that are re-entrained in a collection electrode. However, its collection efficiency can deteriorate, as its operation is subject to water-induced corrosion of the collection electrode. To overcome this drawback, we modified the wet ESP system with the installation of a PVC dust precipitator wherein water is supplied as a replacement of the collection electrode. With this modification, we were able to construct a compact wet ESP with a small specific collection area (SCA, 0.83 m2/(m3/min)) that can acquire a high collection efficiency of fine particles (99.7%).

In this study we researched on the gaseous mercury removal performances of fabric filter (FF), electrostatic precipitator (ESP) and wet flue gas desulfurization (FGD) technologies on 300 MW coal-fired boilers, gaseous mercury sampling was conducted according to US EPA Method 30B and Method 29, and the changes of various forms of mercury before and after the dust removal treatment were analyzed. The results show that FF is the most effective for fine particles removal, and more than 99.5 % of the particulate mercury was removed; the gaseous mercury removal efficiency of ESP was only 30%, while the efficiency of FF was 45% or higher; the combination of FF and wet FGD could remove 63.65 % of the gaseous mercury.

Rigorous new regulations in coal-fired pollutants emissions from power plant strengthen the requirements for electrostatic precipitator (ESP) technology. The study was inspired by the requirement to use the new composite collectors as substitutes for typical steel collector to save energy and structural materials. A bench scale and a pilot scale experimental system have been set up to investigate the performance of the novel wet composite collector. Contrastive collection efficiencies of different assembled modes were investigated. The removals of coal-fired pollutants including acid aerosol, ammonia aerosol, slurry droplets and fine particles were performed in new wet ESP, as well as to quantify the key properties of the new wet ESP. The results show that the collection efficiency of the new composite collector was higher than that by typical collectors using a thimbleful of water penetrating the surface via capillary flow. The new wet ESP device acts in synergy with WFGD and SCR systems for controlling coal-fired pollutants emissions and solves the adverse impacts caused by wet flue gas desulfurization (WFGD) and selective catalytic reduction (SCR) systems at the same time.
