Improvement of Nano Particle Collection Efficiency in an Electrostatic Precipitator

Combination 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...

Laser flow visualization and velocity fields by particle image velocimetry in an electrostatic precipitator model

Although improving electrostatic precipitator (ESP) collection of fine particles (micron and submicron sizes) remains of interest, it is not yet clear whether the turbulent flow patterns caused by the presence of electric field and charge in ESPs advance or deteriorate fine particle precipitation process. In this paper, results of the laser flow visualization and Particle Image Velocimetry (PIV...

Role of Electrostatic Precipitator in Industry

Electrostatic Precipitators (ESP) are most important device used to control the pollution by collecting dust particles present on flue gases. In power plants, Coal used in Indian thermal power stations is of inferior grade, at power plant flue gas is often treated with a series of chemical process and scrubbers, having low calorific value (3500-4500)kcal/kg and high ash content due to drift ori...

Collection of submicron particles using DBD electrostatic precipitator in wire-to-square tube configuration

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...
