Dust Control is a serious problem across the paper manufacturing
and paper converting industries. The paper dust poses fire, maintenance
and operator comfort issues on the machines and throughout the plant.
Most paper manufacturers use area hoods connected to
a vacuum system to collect the dust filled air at various locations
inside and around a machine. These systems rely on ventilating the dust
filled air from the high dust areas. The performance of these systems
are limited for several reasons:
- The area hood systems waits for the dust to get
into the air at random location along the web path before trying to
deal with it.
- The make up air in the room may also have dust in
it reducing the effectiveness of the ventilation concept.
- The area hood systems have to be far from the web
so it does not sucked up the web.
- A substantial amount of vacuum is required to operate
enough area hoods to cover a larger converting or paper machine.
- The area hoods are a reactive approach which do
not deal with the root cause of the problem which is keeping the dust
from getting into the air in the first place.
A large percentage of the paper dust is usually in the
roll and a smaller percentage comes from fibers broken as the web goes
over rollers in a machine. The dust from the the roll will come off
the web at various locations along the web path. If the dust on the
roll can be collected early in the processes this will dramatically
reduce the amount of paper dust in the air and in and around the machine.
This will leave just spot pick ups in locations where dust is generated
by breaking fibers along the web path.
The criteria for such a system would be: 1) able to
operate at various web widths and speeds; 2) not interfere with current
operations and cause web breaks; 3) not require more (and preferably
less) vacuum than the current system.
A new approach:
ElectroStatics has developed a new approach for managing
dust control on the paper making and converting machines by drawing
on its long experience of designing and building web cleaners.
ElectroStatics Dust Collection Systems utilizes an ionized air boost
to neutralize static electricity. This eliminates the electrostatic
field; thus polarization, releasing contaminants for instant vacuum
cleaning in one highly efficient action. It thoroughly neutralizes and
cleans any web in a single operation, the first time through. Removing
the dust directly from the web, before it has the opportunity to get
airborne, dramatically improves the overall efficiency of the dust collection
system compared to area hoods while using the same or less vacuum per
location and usually much less vacuum for the whole machine.
The non contacting web cleaning system, with its patented grooved face
plate, is designed to operate in very close proximity without damaging
the high speed thin web. This allows the ionization, air boost and vacuum
to work together more to more efficiently pickup the paper dust.
Wide web style web cleaners are available to any width web. For systems
less than 30" see our narrow web design
