An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively. The charged particles are then attracted to collector plates carrying the opposite charge. The collected particles may be removed from the collector plates as dry material (dry ESPs), or they ...
May 01, 2014· Sometimes, enough particulate is recovered that it is worth returning to the process. An electrostatic precipitator, or ESP, is one method for removing particulate matter from flue gas. This ...
Depending on the application, the performance of an electrostatic precipitator can be affected by several factors in a rather complicated way. Therefore, practical work with electrostatic precipitators often requires empirical information about the separation process.

Bayer process electrostatic precipitator. It is proven that alumina extraction into solution with bined leaching of bauxite, cake, and electrostatic precipitator dust is higher than with standard bauxite leaching by the Bayer process A favorable effect is achieved due to forming aluminoferruginous hydrogarnets during leaching.
The width of the collection plates in a large electrostatic precipitator can be several meters and the height up to 15 m. An electrostatic precipitator system may include several sections energized from separate high-voltage supplies. The spacing between the plates is typically in the range of 20-40 cm. The gas-flow velocity is typically 0.5-2 m/s.
Normally, the device casing can be made from steel or reinforced plastic. The internal elements of an electrostatic precipitator work together to remove dust from the air stream, contain the removed dust, and release the clean air stream. The primary force used to separate dust from an electrostatic precipitator is electrostatic force. In a ...
7 Construction, Working, Operation and Maintenance of ESPs from the molecules. As a result of losing an electron (which is negative), the gas molecules become positively charged, that is, they become positive ions as shown in above figure.
Electrostatic precipitator THE PERFECT DESIGN MAKES THE DIFFERENCE Forward-thinking technology for flue gas dedusting. Designing electrostatic precipitators for flue gas cleaning after combustion processes requires a great deal of process expertise, as a huge number of parameters need to be taken into account.
Electrostatic Precipitator : A very simple to make but very useful thing. First of all let me explain What acutally an ELECTROSTATIC PRECIPITATOR is. Electrostatic precipitation is a method of dust collection that uses electrostatic forces, and consists of discharge wires and collecting plates.
Using an Electrostatic Precipitator at Home When created for residential use, electrostatic precipitators are commonly called electronic air cleaners or simply "ESP's" (for ElectroStatic Precipitator). These air purifiers typically pull air first over an initial air filter, then pass the air over an electro-charging process.
Electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues. The precipitator functions by applying energy only to the particulate matter being collected, without significantly impeding the flow of gases.
How does an electrostatic precipitator work? Electrostatic precipitation is an extremely efficient way of filtering fine particles from a flowing gas. Electrostatic precipitators (ESPs) can handle large volumes of air without significantly slowing down the rate of flow, because of the low pressure drop across the electrostatic filter.
Rappers are used to transmit strong shearing forces to collecting plates in order to release deposited dust particles. Rapping is the process by which electrodes and particles are broken apart by vibrations from the rappers. Often used in electrostatic precipitators, rappers relapse the caked on dust layer which then descends into a hopper.
The alumina powder from electrostatic precipitator (EP) is a residue generated in the last stage of the Bayer process, during the calcination of aluminium hydroxide ( Figure 10).
B&W's electrostatic precipitator technologies deliver maximum particulate removal efficiency with proven reliability and reduced operating and maintenance costs. And our engineered upgrades, quality components and replacement parts, and aftermarket services help keep existing ESPs running efficiently and effectively, regardless of OEM.

In many industrial plants, particulate matter created in the industrial process is carried as dust in the hot exhaust gases. These dust-laden gases pass through an electrostatic precipitator that collects most of the dust. Cleaned gas then passes out of the precipitator and through a stack to the atmosphere.
