Hualai Vapor Liquid Separator Wire Mesh Pad Both Ss And Plastic
Material
The wire mesh pad demister is usually used to eliminate the mist sizing from 3um to 5um,
which is entrained in the flue gas.
The demister pad is normally constructed by wire mesh pad and
grids. And the popular mesh pad thickness is 100mm and 150mm.
In production, the knitted wire mesh are crimped and layed one by
one layer. The corrugation inclination of neighboring layers shall
be opposite.
Material of vapor liquid separator construction and its
application:
| Materials | Main Application Area |
| SS304 | Water solutions, Nitric acid reduced crude petroleum fraction etc. |
| SS316L | Fatty acid reduced crude containing naphthenic acids and corrosive
chemicals |
| Synthetic fiber | For corrosive service at moderate temperature |
| PP(Polypropylene) | For corrosive service at temperature up to 70℃ |
| PTFE | For corrosive service at temperature of (-190℃, 250℃) |
| Monel | Caustic soda, dilute acid |
| Nickel | Caustic Soda, food products |
| Copper | Freon, alcohol |
| Aluminium | Nitric Acid |
When all the sections attached together, the size of the whole
demister shall be a little bigger than the inner size of tower
(usually measured in diameter). There is a reference standard as
follows:
If we set the bigger value is e, then e = 10mm for towers with
inner diameter 300mm - 1000mm; e = 20 for towers 1100mm - 2000mm; e
= 1%*diameter, when it is bigger than 2000mm.
When we install the demister to the tower, no gap is allowed either
between the mesh pad and the tower wall, or between the sections of
mesh pads.
The mesh pad thickness can be calculated from the requirement of
eliminating efficiency.
The mesh pad demister shall be inspected and cleaned periodically,
so to ensure the desired efficiency and avoid pressure drop
increasing.
Most demisters are replaced on a regular basis due to fouling or
corrosion.
When moved out of the towers, the demister shall be cleaned and
blow-dried in time, to avoid corrosion.
