Dry Electrostatic Precipitators

The Vapor electrostatic precipitator can be used to separate micro-fine dust particles form hot processes gases of 350-400 Degree Celsius. Therefore, ESP is used in boiler plants and various chemical process industries.Principle of Operation The dust contaminated process gas enters the electrostatic precipitator horizontally and is distributed uniformly across the entire filter cross section through perfect gas distribution systemElectrical field is generated between the corona discharge electrodes and the collecting electrode plates by applying high voltage. The process gas and dust particles are electrically chargedThe charged particles are transported to the collecting electrodes plates by electric field strength, where they agglomerates with the existing dust particles. The collected dust particles are removed from the collecting surface by mechanical rapping hammer systemThe removed dust particles dropped into hopper bellow and are removed through dust collection systemThe purified gas leaves ESP Short Description of the Technology        Gas distribution screen are provided at inlet and outlet as per computer modelling for proper gas distribution in ESPHorizontal passage of the ESP consist of the suspended collecting electrodes in plate construction with dust collecting channels. These helps to maintain uniform electric field and smooth removal of collected dust particles without re-entrainment of dustHigh performance discharge electrodes are made of special stainless steel strip and are arranged in the center. A suitable clearance is given between mounting of the framing and discharge electrodeA simplified mechanical rapping hammer mechanism is used to knocked of dust particles from corona discharge electrodes and collecting plates electrodesTransformer-Rectifier sets supply specified DC Voltage and current to the field Electrostatic PrecipitatorLow Power Consumption of the electric systemElectric heating of the insulator and hooper (in special cases) are providedPyramidal hopper and dust conveying system are provided to prevent accumulation of dustHigh performance of separation ensured by current high voltage control system Advantages Separation of micro-fine dust particles to meet the required Emission Norms.Low pressure drop.Low energy cost compared to fabric filter dust collector/Bag Filter.Low maintenance and required only one maintenance per year.Continuous dust collecting processHigh gas temperature up to 350-400 degree Celsius.Design for low to very high volume of gas.High Collection Efficiency.
