Wire Mesh Demister Mist Eliminators Standard Specification

1.General introduction of wire mesh demister

Wire mesh demister is used to separate mixture of vapor liquid in some industrial applications. Sometimes a vapor-liquid separator may also referred to as a flash drum, knock-out drum, compressor suction drum or compressor inlet drum. It is usually called mist eliminator when used to remove suspended water droplet from air stream.

Normally, in the vertical vessels, the liquid drops to the bottom, where they are withdrawn, as the force of gravity. But in low gravity environments like a space station, the gravity is not usable effectively. At this time, centrifugal force needs to be utilised in a spinning centrifugal separator to drive liquid droplets to the outer edge of the device while gas migrates to the centre.
In either way of separation, the gas outlet can be surrounded by a spinning mesh screen or grating. If any droplets occasionally reach the outlet, they will strike the grating, be accelerated and thrown away from the outlet.
The vapor goes through the mist eliminator at a designed velocity which minimizes the re-entrainment of any liquid droplets.
The feed to a vapor-liquid separator may also be a kind of liquid which is being partially or totally flashed into a vapor when it enters the device.

Only when there is air space inside the chamber, the vapor-liquid separator is effective. It can fail either when the mixed stream inlet is overwhelmed or the draining of collected liquid is slower than its growing. Considering this, the separator may be combined with some liquid level sensing accessories, such as a sight glass or float sensor. By doing this, both the supply and drain flow can be regulated to prevent the separator from being overloaded.

3.Material of construction and its application:

4. How does a demister pad work?

(1)A vapor stream carrying entrained liquid droplets passes through a demister pad. The vapor moves freely through the knitted mesh.

(2)The inertia of the droplets causes them to contact the wire surfaces and coalesce.

(3)The large, coalesced droplets formed in the mesh ultimately drain and drop to the vessel bottom.
