Wet Electrostatic Precipitator (WESP)

With increasing demand, world-wide, for reduction of respirable particulate and aerosols from various industrial processes, Wet Electrostatic Precipitator (Wet ESP) technology from Enviropol – Envibat is gaining recognition due to its ability to capture sub-micron particulate with condensed acid mist unlike other dry separation technologies like Bag Filter & Dry ESP.

Enviropol Engineers is a leading wet electrostatic precipitator suppliers, manufacturers, and exporters from India. We are supplying highly advanced wet type electrostatic precipitator around the world at the most competitive prices.

Working Principle of Wet Type Electrostatic Precipitator:

Gas ConditioningThe dust laden hot flue gases are first conditioned to near saturation to make it more conductive for charging through water spraying. For high dust loading, low pressure drop scrubbing is used for conditioning and reducing the dust load.

ChargingSaturated gas with fine particulate enters the charging section and given strong negative charge by ionizing corona produced by high voltage electrodes.

CollectingThe electrical filed causes charged particles to migrate to the grounded walls of the tube where they accumulate.

RemovingThe falling water film inside the tubes removes the collected material to a discharge drain.

Advantages of Wet ESP

  • Ability To Capture High Resistivity (>1010 Ohm-Cm) Particulate
  • Low Outlet Emission - Even Below 10mg/Nm3
  • Substantial Reduction Of Gaseous Pollutants H2 SO4 Mist & So2
  • Ability To Capture Hg+2 And HCl
  • Low Specific Collecting Area
  • Ability To Handle Sticky Dust
  • No Rapper Re-Entrainment
  • No Fire Hazards
  • Smaller Foot Prints

Our Manufacturing Range

  • Square /Round/Honeycomb Construction
  • Tower Construction With Integrated Stack

Upgrade Your Existing Wet Scrubbers To WESP

An opportunity exists, for the users of operating Bio-mass Fired Boilers with Wet Scrubbers, to upgrade their existing system to WESP for more effective control of emission of fine particulate and acid mist.

Modular design and adaptability to fit into existing wet scrubber makes installation easy. WESP has proved to be an effective and more economical solution for air pollution control for the boilers being converted for multi fuel firing application.
