Removal of Particulate Matter in a Tubular Wet Electrostatic Precipitator Using a Water Collection Electrode
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 w...
متن کاملNovel Wet Electrostatic Precipitator for Sub - Micron Particles
The waste incineration plants, power generation utility, chemical industry, etc. require the efficient removal of submicrometer particles from raw gases. Wet electrostatic precipitators (WESP) are the most effective control device for fine aerosol from the humid raw gases. They use less energy than mechanical collection devices, have no moving parts to wear, their maintenance costs are lower, p...
متن کاملCombination of Electrospray with Electrostatic Precipitator for Collection Efficiency Enhancement of Fine Particles
Electrospray was employed upstream of an electrostatic precipitator (ESP) to enhance the collection efficiency of monodisperse nanometer-sized particles. The electrospray of deionized water produced water droplets with a size range from several tens to several hundreds μm. The visible combined effect of the ESP with the electrospray was found for the collection of particles larger than about 20...
متن کاملPerformance of a pilot-scale wet electrostatic precipitator for the control of sulfuric acid mist.
The use of a wet electrostatic precipitator (WESP) is often regarded as a viable option to reduce sulfuric acid mist emitted from the wet flue gas desulfurization (WFGD) tower in coal-fired power plants. In this study, a pilot-scale wet electrostatic precipitator equipped with a wall-cooled collection electrode is investigated for the control of sulfuric acid mist from a simulated WFGD system. ...
متن کاملSpark and Its Effect on Electrostatic Precipitator
The role of components in an Electrostatic Precipitator (EP) for a spark and both the phenomenon and mechanism of a spark are elaborated and then the type of spark is classified by the condition of shortage between the discharge and collecting electrodes. The secondary voltage and current waveforms of a spark are discussed in order to address the severe effect of the secondary and primary curre...
