2. Features
Wire Mesh Demister
Wire mesh mist eliminator also known as wire mesh demister, is a
kind of vapor liquid separating device.It is made up of many
corrugated gas liquid filter net,a grid and a fixed distance rod
.It is most often used to separate liquid drop with diameter of
more than 3-5 μm in the separation tower.It can ensure the mass
transfer efficiency,reduce the loss of valuable materials after
operation of compressor, commonly setted in the top of device.It is
widely used in gas-liquid separation in chemical, petroleum,
sulfate, medicine, light industry, metallurgy, machine, building,
construction, aviation, shipping and environment protection.
Size and structure can be customized according to customer's
drawings.
Duplex stainless steel 2205 alloy is a duplex stainless steel
composed of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness and
good overall and local stress corrosion resistance.
The yield strength of 2205 duplex stainless steel is more than
twice that of ordinary austenitic stainless steel, which makes the
designer reduce the weight when designing the product, and makes
this alloy have more price advantage than 316, 317l. This alloy is
particularly suitable for temperatures in the range of - 50°F / +
600°F. For applications beyond this temperature range, this alloy
can also be considered, but there are some limitations, especially
for welded structures.
3. Application about Tower internals Stainless steel Wire mesh demister pad for
gas-liquid filters

·Pulp and paper industry classifiers, bleaching equipment, storage
and processing systems.
·Rotary shaft, press roll, blade, impeller, etc. in high strength
and corrosion resistant environment.
·Cargo box of ship or truck
·Food processing equipment
4. Material Comparison about Tower internals Stainless steel Wire
mesh demister pad for gas-liquid filters
Difference between duplex 2205 stainless steel plate and Austenitic
304 stainless steel plate
1) The yield strength of austenitic stainless steel is more than
twice as high as that of ordinary austenitic stainless steel
Enough plastic toughness. The wall thickness of the tank or
pressure vessel made of duplex stainless steel is 30-50% less than
that of austenite, which is helpful to reduce the cost.
2) Even duplex stainless steel with the lowest alloy content has a
higher ability of stress corrosion cracking resistance than
austenitic stainless steel, especially in chloride containing
environment. Stress corrosion is an outstanding problem difficult
to solve for normal austenitic stainless steel.
3) The corrosion resistance of 2205 duplex stainless steel, which
is widely used in many media, is better than that of 316L
austenitic stainless steel, while super duplex stainless steel has
very high corrosion resistance. In some media, such as acetic acid,
formic acid, etc., it can even replace high alloy austenitic
stainless steel and even corrosion resistant alloy.
4) Compared with austenitic stainless steel with the same alloy
content, it has better wear resistance and fatigue corrosion
resistance than austenitic stainless steel.
5) Compared with austenitic stainless steel, the coefficient of
linear expansion is lower, close to carbon steel, suitable for
connection with carbon steel, which has important engineering
significance, such as production of composite plates or linings.
6) No matter in the condition of dynamic or static load, it has
higher energy absorption capacity than austenitic stainless steel,
which has obvious advantages and practical application value for
structural members to deal with sudden accidents such as collision,
explosion, etc.
5. Advantages:
High removal efficiency
Negligible pressure drop, less than 25mm of water gauge
No maintenance or service required
No corrosion or temperature limitations
Easily installed in existing vessels
No limitation on size or shape.
