Electrostatic   precipitators (ESP) Matti Rinne-Kanto & Mikko Vihanto 06I252 TAMK University of Applied Sciences 7 June 2009
This presentation introduces how ESPs work and where they are used Operational principle ,[object Object],Applications and conclusion
This presentation introduces how ESPs work and where they are used Operational principle ,[object Object],Applications and conclusion
A row of electrodes A stack of metal plates   Gravity drops particles into the hopper The ionized particles moves to the grounded plates Incoming air stream Cleaned air The precipitator’s operational principle uses negative voltage to  ionize particles A negative voltage of several kVs is applied
This presentation introduces how ESPs work and where they are used Operational principle ,[object Object],Applications and conclusion
ESPs can be divided into three groups: plate precipitators, wet ESPs and modern industrial ESPs Plate precipitators -  Cheapest and most simple - The plate and wire assembly can vary in different solutions - The lowest efficiency, but still reasonable for most applications
Wet ESPs - The most expensive and the most complex - Disposal of the laden water is a problem   - Water helps reducing the electrical resistance of the incoming particles to make the process more effective   ESPs can be divided into three groups: plate precipitators, wet ESPs and modern industrial ESPs
Modern industrial   ESPs - S harpened spikes are attached to maximize corona production   - Modern automation minimizes sparking and avoids damaging  components   - Uses voltages of 50–100 kV   ESPs can be divided into three groups: plate precipitators, wet ESPs and modern industrial ESPs
This presentation introduces how ESPs work and where they are used Operational principle ,[object Object],Applications and conclusion
ESPs have applications in the field of industry and customer oriented applications -  Cleaning combustion gases and reducing VOC emissions at  different kind of factories   Industry
- Electrostatic channel filters -   Electrostatic air cleaners ,[object Object],- Maximum air capacity  ,[object Object],[object Object],[object Object],[object Object],[object Object],Used on offices and large rooms ESPs have applications in the field of industry and  customer oriented applications
+ Can be used in a wide area in  industry and in other applications + Operational principle is simple ESPs have advantages and disadvantages + Good example of a device designed by electrical engineers to help the environment   - Efficiency is dependent of the electrical properties of the particles   - Limitations of usage, maintenance and production
This presentation introduced how ESPs work and where they are used Operational principle ,[object Object],Applications and conclusion Questions???
