With  increasing demand, world-wide, for reduction of respirable particulate and aerosols from various industrial process, WESP technology from Enviropol-Envibat is gaining recognition due to its ability to capture sub-micron particulate with condensed acid mist unlike other dry separation techniques like Filter & Dry ESP.

Feature:

  • Wide range of application (Dust resistivity is not a factor)
  • No fire hazard (Wet atmosphere)
  • No moving parts (Absence of rappers)
  • Smaller footprints(Honey comb design)
  • Corrosion & Erosion resistant (SS Construction)
  • Rigid Discharge Electrodes (Better life)
  • Better charging (High gas velocity)
  • Modular design (Easy installation)

Why WESP?

  • Ability to capture high resistivity(>1010 ohm-cm) particulate
  • Low Outlet emission – even below 10mg/Nm³
  • Substantial reduction of gaseous pollutants
  • Low specific collection area
  • Ability to handle sticky dust
  • No rapper re-entrainment
….Upgrade your existing Wet Scrubbers to WESP

An opportunity exists, for the user 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 the boilers being converted for multi fuel firing application.
   

Working principle:

After the scrubbing section the fine dust laden gasses enters the WESP. The precipitation of dust and aerosols is done in three stages:

Charging
Particulate are given strong negative charge by ionizing corona produced by high voltage electrodes.

Collecting
The electrical field causes charged particles to migrate to the electrical grounded walls of the tube where they accumulate.

Removing
The falling water film inside the tubes removes the collected material to drain to the scrubber below or to a discharge drain. To stay clean the tubes are periodical back flushed
