Do electrostatic precipitators make good mist collectors?
Yes. In fact, electrostatic precipitators have been used successfully
for over 60 years in numerous industrial air filtration applications.
It is a time proven technology. With HEPA-like efficiencies, electrostatic
precipitators are among the most efficient mist collectors on the market today.
Electrostatic precipitators work by pulling polluted air through an
ionized field, which charges the particles. Those particles then pass
through a collection cell made up of positive and negative charged plates,
which attract or repel the charged particles. The charged particles attach
to the collection cell plates and are effectively removed from the air stream.
When collecting mist and oily smoke, mist particles will combine with other mist
particles and form droplets. When the droplets become large enough, they drip
off the collection cell, effectively cleaning the collection cell and reducing
maintenance.
Unfortunately, the electrostatic precipitator has received bad publicity
from companies that specialize in and make their profit by selling aftermarket
filters. Most filter-type mist collectors today are designed to provide about
one year of filter life before filter changing is required. If you purchase a
1000 to 1300 CFM mist collector for a mist and light smoke application, you
probably paid between $5,000 and $10,000, including complete installation,
ducted and wired. Each year, that same system can cost over $1,000 to do a
complete filter change-out. In 10 years time, you may pay as much or more
in replacement filters than the initial price of the mist collector.
The filter companies know that electrostatic precipitators do not work
on all mist applications. Trion agrees. No single mist collector works
best for all mist applications. In fact, many mist applications today
require that a “standard” configuration mist collector be reconfigured
to provide optimal service life. Electrostatic precipitators can also
require reconfiguring to optimize the system to your specific application
needs.
