|Principal of Operation:
The Anderson Filter Separator is a multi-stage separator that
provides optimal removal of both Liquids and Solids from a
gas stream. As the contaminated gas passes through the
filter separator it must pass through several distinct regions
or stages. Each stage has a specific purpose, and the
cumulative effect provides a virtual contaminant free gas.
First, the contaminated gas encounters a large inlet plenum,
which contains the filter support tubes. The gas stream
velocity reduces in the plenum, and bulk separation occurs
due to gravity. Further separation occurs as a result
of the filter support tubes. The gas contaminants impinge
on these tubes, coalesce into larger particles and drop to
the lower portion of the inlet chamber. In addition,
as the gas tries to negotiate this maze of tubes, a centrifugal
force is imparted on the gas. This centrifugal force
will remove liquid and solid particulate down to 10 microns. The
separated liquids and solids then drain to the sump.
Next, the gas must pass through the filter elements. The
solid particulate is captured on the surface of the filter,
and in the depth of the filter media. The fine liquid
particles flow through the elements, and coalesce with other
liquid particles to form larger particles. These larger
particles emerge from the inner core and are carried downstream
to the final separation region. The filter elements are arranged
in a triangular pith to provide the maximum number of filters,
and filter area for a given vessel size. These elements
are arranged to provide equal flow through the Separation Chamber. This
stage utilizes one of several Anderson High Efficiency Separation
Elements. These elements will remove virtually all coalesced
liquid flowing from the filter elements.
