Mist Eliminator Filter Use in Bio-Scrubber or Air Handling Systems
1. Mist Eliminator Filter Description
Demister Pad, also called mist pad, wire mesh demister, mesh mist
eliminator, catching mist, mist eliminator. Demister Pads are woven
with multi-layer knitted mesh in different densities. It is used in
gas entrained mist separation column to guarantee the filtering
Demister pad is porous blankets of metal wire or plastic knitted
mesh, designed and constructed for the efficient, economical
removal of entrained liquid droplets from vapor streams.
Demister pad Mesh is normally knit from wires ranging in diameter
from .0035” to .0200”. In special applications, Metal Textiles has
knit wires ranging in diameter from .0005” to .0350”. These wires
can be round or flat such as those used in Metal Textiles copper
gauze for cleaning and in air-filtration applications where large
surface areas of wire are needed. A round wire when flattened has
approximately twice as much surface area.
Infiltration applications, wire diameter is perhaps the most
important design variable. It directly affects flow, dirt holding
capacity, pressure drop, and cost. In general, larger diameter wire
allows for higher flow but provides lower dirt holding
capacity. Also, a larger diameter wire is less expensive.
Therefore, a balance must be struck between using a higher density
filter of higher cost fine wire or a lesser density filter using
lower-cost heavy wire.
Density refers to the mass of material per unit volume. It is
related to the density of the original mesh and the amount of
forming pressure used to compress the mesh into its final form.
Determining the required mesh density to produce the specified
final product density is a critical step in the design process.
Proper density ensures optimal performance of the
sealing,gasketing, filtration, heat transfer and separation
Material Of Construction
Demister Mesh also named knitted wire mesh, gas-liquid mesh, foam
net, wire mesh demister, knitting mesh, demister mesh pad. It is
one of using crocheted weaving woven wire mesh. Products are mainly
used for gas-liquid separation and despumate in oil; chemical
industry, automobile industry, environmental protection. It can
also be used electromagnetic shielding in construction engineering.
Demister Mesh can be made of stainless steel wire, copper wire,
galvanized wire, PTFE wire, flat galvanized steel wire, etc.
2. Mist Eliminator Filter Features
Knitted metal has distinct advantages over most competitive
materials. Because each loop acts as a small spring when subjected
to tensile or compressive stress, knitted metal has an inherent
resiliency. If it’s not distorted beyond its yield point, the
material will resume its original shape when the stress is removed.
Even when it’s compressed into a special shape, a high degree of
resiliency is retained. Varying the knitted structure, wire
diameter, wire material and forming pressure used to create the
part can control this characteristic.
Knitted metal also provides high mechanical damping characteristics
and non-linear spring rates. Vibration and mechanical shock can be
effectively controlled to eliminate the violent resonant conditions
and provide ample protection from dynamic overloads.
In compressed form, knitted metal can handle shock loadings up to
the yield strength of the material itself. The load may be
applied from any direction—up, down or in from all sides. Our
application engineers have the experience to determine the optimum
density of compressed units within the range of 10% to 70%. This is
important in applications such as liquid filtration and noise
attenuation where flow resistance is critical. When compressed,
layered, calendared or wound knitted metal presents a “torturous”
path to liquids or gasses flowing through it. This increases
filtration capability and particle retention capacity.
Among the most important property of knitted mesh units is the
material itself. By careful selection of the material or
combinations of materials, Metal Textiles can custom engineer
solutions best suited for our customer’s application—be it
corrosive, ultra-high or cryogenic temperature, high pressure,
radioactive, dirty, oily or other extreme conditions.
* Various materials. Different material knitted wire mesh can be
used in various applications for different requirements.
* Solid structure. The interlocking structure of knitted wire mesh
makes the structure is solid, which will not loose when using.
* High efficiency. The knitted wire mesh can be used as a demister
pad for high filtering efficiency.
* Corrosion and rust resistance.
* Acid and alkali resistance.
* Temperature resistance.
* Wide range of applications.
