Drawer Type PP Mesh Gas Liquid Separator Key Parts Mist Eliminator
Wire mesh demister is a kind of gas liquid separation device. When the gas passes through the mesh pad, the mist
entrained can be eliminated. The drawer type wire mesh demister is
constructed by several sections of demister pad. They are installed
into the column by slideway. It is convenient for maintenance and
replacement, which can be done from outside of the column.
The applicable gas velocity of demister (calculated by the effective cross-sectional area of gas passing
through the demister): 2.5-4.5 m / s; the appropriate gas velocity
for sulfuric acid industry is 3-4 m / s.
The user can choose one layer or two layers of drawer type wire
mesh demister according to technical requirement. When two layers
of demisters are needed, the wire mesh pad should be in accordance
with the principle of increasing mesh density from top to bottom.
There also should be a certain distance between two layers of wire
mesh demisters. Usually it is recommended to be 450mm when the
tower inner diameter is less than 1000mm, and 600mm when the tower
inner diameter is bigger than 1200mm.

The diameter means the inner diameter of tower or column the drawer
type demister to be installed in.
The weight of demisters is calculated and estimated based on
stainless steel material.
The length of single piece of demister is recommended to be less
than 1400mm. When the tower inner diameter requires a length over
1400mm, the single piece of demister pad can be devided into
shorter sections, connected with hooks when installation.
