Wire Mesh Pad Gas Liquid Separator Average Sections HL-Donut Band
The wire mesh demister is installed above the surface of the liquid with some distance.
From one hand it allows some space for the natural disengagement of
the coarsest natural particles. From the other hand, it ensures
that the gas/ vapour flow is uniform over the whole area of the
mist eliminator
The gas / vapor containing droplets passes into mesh pad demister
at a predetermined velocity. It easily finds open path through the
mesh but the droplets and mist impinge on the filaments of mesh
where they coalesce and eventually grow to such a size to overcome
surface tension of liquid and force of gravity. Then the liquid
droplets so formed fall down. And the mist free gas / vapour passes
through the mesh demister pad.
Here we introduce a new method of making donut shape demister pad vapor liquid sepators. Except the popular long strip segment
method, we can also divide the circle averagely into flabellate
sections. In this way, it may be easier to install and mainten the
demister pad than the other method. While actually speaking, it
does require more labor and material cost in workshop. 
More knowledge we have in the application of demister vapor liquid
separator with different mesh types:
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 wire mesh demister pad can provide:
1. Simple installation;
2. Low pressure loss;
3. 90% to 99.9% efficiency;
4. Little maintenance is required;
5. Elimination of liquid product loss;
6. Essential improvement of vapor phase quality;
7. Dimensions and configurations are not limited;
8. Contacting surface area is larger than the specific gravity;
9. No direct power is required since the equipment has no operating
parts
10. Compact equipment can be used in accordance with increased
production capacity
