"For small to medium sized dust particles, bag
house dust collectors are an ideal solution..."
Baghouse dust collectors,
one of the most efficient and cost effective types of dust collectors
available, can achieve a
collection efficiency of more than 99% for very fine particles. This
is due to dust particles loading on the filtration media, helping to block
other particles as they approach in the air stream.
What
separates a Baghouse dust collector from
other dust
collector types?
In a bag house dust
collector, contaminated air enters and passes through variably efficient
media filtration bags. These bags can consist of a number of different
materials, woven together to form a cross-hatched pattern of filter media.
Some dust is more abrasive than others, so there are more durable bags
available for particles, such as concrete and asphalt dust, diatomacious
earth, granite, and many others.
Types of Baghouse
Dust Collectors...
Mechanical Shaker
In
this type of dust collector, the filter bags are shaken as they
become more agglomerated with dust particles, preventing dust
re-entrainment. This keeps the filters from achieving potential
maximum efficiency, but reduces maintenance time and filter replacement
cost.
The design simplicity of the mechanical shaker type baghouse dust
collector is one of the reasons it is so popular in today's industry.
Reverse Air
Airflow is created both clockwise and counter-clockwise in this type
of dust collector to filter out the contaminants. The down side to
using this method, however, is the amount of increased maintenance compared
to other types. This maintenance is the result of dust re-entrainment
on the filter bags.
Reverse Jet
In a reverse-jet baghouse dust collector, contaminants enter from
the lower portion of the filter housing, where a metal cage is incorporated
to support the filter bag and prevent collapse.
By supplying a compressed air line to the baghouse, it is possible to
achieve a nearly self-running operation; as the dust collector uses the
compressed air to pulse the filter bags, dust is blown down into your
designated collection bin.
