CGS Wet Electrostatic Precipitators
| WESP (WET
ELECTROSTATIC PRECIPITATOR)
Electrostatic Precipitation Technology has been used successfully
for many decades. It has made possible the capturing of sub-micron
particles without the need for a Venturi type Scrubber which requires
very high pressure drop. A Wet Electrostatic Precipitator utilizes
liquid sprays to wash down the collected dust particles from the
collector surface. What sets CG-WESP apart from other conventional
WESP designs is our unique Hexagonal Grid type Collector with wide
open design, rigid electrodes, and vertical counter current action.
CG-WESP offers the maximum collector area (SCA) and the most power
intensity level and, hence, the most efficient performance.
Here is how CGS' Hexagonal Tube Collector design compares
with some of the conventional type designs:

CG-WESP ... YOUR BEST
CHOICE !!
Efficiency of a Wet Electrostatic Precipitator increases with increase
in Specific Collector Area, "SCA," normally indicated as square
feet per 1000 saturated ACFM of gas flow. The other major contributing
factor is Corona Power normally indicated as Watts per ACFM. These
curves indicate how a higher power level can provide a higher efficiency.
CG-WESP offers the highest "SCA" and Power Intensity levels available,
and achieves the most efficient performance. CLEARLY A WINNER! |
