Electrostatic precipitator

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). ESPs designed & Supplied by Dynepro Private lImited are capable of collection efficiencies greater than 99 percent. An ESP is primarily made up of the following four components: gas distribution plates, discharge electrodes, collection surfaces (either plates or pipes) and rappers. The gas distribution plates consist of several perforated plates which help maintain proper flow distribution of the entering gas stream. The discharge electrodes are divided into fields. Most ESPs have three or four fields in series; however, very large units may have as many as fourteen fields in series. Discharge electrodes are energized by a single transformer-rectifier (T-R) set power supply. The energized electrodes create ions that collide with the particles and apply the electrical charge to the particles contained in the incoming gas stream. The collection plates or pipes provide the collection surfaces for the charged particulate matter. The rapping system is responsible for removing the collected particulate matter from the collection surfaces. Dynepro’s ESPs are designed with Optimum Aspect ratio , Migration velocity & Treatment time taking in to account of various factors & Characteristics of the Flue gas, its particle size, particle resistivity etc., Thus, the design is able to achieve the deliverables of desired outlet dust concentration to meet the statutory norms with increased Collection Efficiency. The Technical team of the ESP division has the expertise of having designed more than 300 ESP’s across the nation.
