Application or technical questions?
The Monroe Wet Electrostatic Precipitator (WESP) is a state-of-the-art pollution control system for PM2.5, sub-micron, and fine particulate control. Monroe Wet ESPs feature NAPCO patented filtration technology, a unique configuration and high voltage collection area design which provides for better collection efficiency and lower energy consumption versus competitive systems.
Monroe Wet ESP Design
Monroe Environmental Wet Electrostatic Precipitator systems are designed to meet the most stringent PM2.5, opacity, and condensable particulate regulations.
The high intensity corona provides particle charging fields that are two to three times stronger than those of conventional precipitators – resulting in higher particulate charges, higher migration velocities, and smaller precipitator size.
As such, the Monroe WESP delivers extremely high reliability and outstanding collection performance.
Benefits of a Monroe Wet Electrostatic Precipitator
- Reduced Installation Time: Prefabricated skid-mounted electrostatic precipitator modules assemble easily and quickly – often in a day or less of crane time.
- Low Maintenance: All components that are exposed to the gas streams can be manufactured with stainless steel or specialty alloys for long life and low maintenance. Systems can be designed with no moving parts.
- High Collection Efficiency: The unique and patented wet precipitation design provides for high collection surface area resulting in high particulate collection efficiency. Efficiencies of up to 99.9% have been achieved.
- Zero Discharge: Systems can be designed with zero discharge if required. Monroe’s wastewater treatment expertise allows for efficient removal of solids and condensed liquids.
- Low Energy Consumption: The patented design allows for lower energy consumption than conventional wet precipitator systems.
How a Monroe Wet Electrostatic Precipitator Works
- The hot-polluted gas passes through an optional pre-scrubber, where it is cooled to its adiabatic saturation temperature. Particles above five microns are removed and vapors condense into fine mist.
- The particle and mist-laden gas stream then enters the Wet Electrostatic Precipitator.
- The gas passes through air distribution baffles. Small liquid droplets are added to the gas stream from the fog headers.
- The particles, mist, and droplets are charged and removed from the gas by the high voltage electrical field.
- The particles, mist, and droplets coalesce and drip into the conditioning section and are removed via the drain.
- The clean cool gas leaves the Wet Electrostatic Precipitator.
Modular, Adaptive WESP Designs Customized to Your Application
The Monroe Wet Electrostatic Precipitator System also offers the user maximum flexibility through a choice of innovative, adaptable modular designs that can meet any application or system layout requirement. Depending upon the particular contaminant properties and gas stream contents, the system can be configured to meet specific customer needs.
