300mm Mesh Pad Demister Mist Eliminator For 1 - 3 Um Fine Droplet
The demister mist eliminator is designed to collect liquid particles contained in the vapour
phase after boiling, vacuum evaporation or bubbling process.
Small droplets in the gas contact the wide surface of the filaments
of the mesh pad demister, gradually grow into large liquid droplets
and flow and drop by a special structure accelerating the
coalescing of the liquid droplets. The mesh pad of the demister is
highly porous, so the vapour gas passes through the demister
without hindrance, leaving only pure gas.
The process is not a type of filtering as the hole size of the knit
mesh is not specially related to the size of the liquid droplets.
This mist elimination is caused by the collision and sudden change
resulting from the flowing speed of the small liquid droplets, and
the coalescing of the liquid drips and gravity cause their descent.

It is appropriate for collecting very fine particles (1-3 micron)
and effective for evaporator, washing equipment, compressor and
absorption column, etc. Normally, 200mm to 300mm thickness mesh pad
is used.
More types of demister mist eliminators and applications:
Mesh Density | Eq to: YORK | Description |
| 80 | 931 | For a given load of mist, the highest flow velocity is achieved of
all styles. Ideal where it is required to minimize the pressure
loss, possible clogging is concerned, the size of particle to be
collected is relatively large, and/or a very high efficiency is not
required. |
| 144 | 431 | Used for general purposes. An efficiency of 98 to 99% is achieved
at a velocity of 1 to 5 m/sec. |
| 192 | 421 | Used where an especially high efficiency is required. While a
pressure loss is slightly higher, it achieves an efficiency of 99
to 100% with particle sizes 3μ or more at a velocity of 1 to 6
m/sec., and is ideal where an efficiency of 90% or more is required
at a velocity of 1 m/sec. or less. |
| 216 | | Used for collecting fine particles of 1 to 3μ in size.
Especially for a low-density mist of 1.0 g or less, it is used in a
thickness of 200 to 300 mm. |
| 432 | 333 | Used for collecting fine particles. An efficiency higher than that
of 216 can be achieved. The most remarkable characteristic is that
it provides a high efficiency with a reduced thickness. |
Advantages of demister mist eliminator:
Prevention of air pollution
Reduce of costly liquid lose
Reduce of product contamination
Improvement in process efficiency
Minimizing product losses in re-boilers & evaporators
Preventing carbon & metal entrainment in down stream catalyst
cracker.
