Stainless Steel York Mesh 421 Demister Pad For Liquid And Gas
Seperation
Description of Demister Pad
Knitted wire mesh demister pad is also known as mist eliminator or
sprays. Knitted wire mesh demister pad is supplied in standard,
high efficiency and high permeability. Demister Pads are
essentially porous blankets of carefully knitted wire mesh designed
and constructed to efficiently abate mist particles. Demister pad
is mainly used to eliminate streams with diameter of more than 3μm
to 5μm.
Knitted wire diameter used for the knitting directly affects flow,
dirt holding capacity, pressure drop and cost. Knitted wire mesh
demister pad is used to separate in the most efficient manner the
very fine drops carried away by a gas or steam, either at a boiling
stage, vacuum evaporation or bubbling of a liquid. In fact there
are two phenomena, one mechanical and one physical, but no
filtration at all since the size of the held drops has no relation
with the infinitely greater size of the pore or open space. The
head loss or gas passage resistance is practically imperceptible,
however demisting can reach up to 99% efficiency. A demister
reaches the highest efficiency when the speed of a gas or steam
ranges between certain limits.

*Desalination plants
Installation of Demister Pad
The wire mesh demister is selected from the top-loading type and
the bottom-loading type wire mesh demister: when the position of
the hole is opened on the top of the wire mesh demister, or when
there is no hole in the hole, the top-loading type wire mesh is
selected. Defoamer; when the hole is opened under the wire mesh
demister, the bottom-loading wire mesh demister is selected.
