Pp Wire Mesh Demister For Vessel System Washing Tower
Pp Wire Mesh Demister Information
Normally, in the vertical vessels, the liquid drops to the bottom, where they are withdrawn, as the force of gravity.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.

Working Principle Of Wire Mesh Demister
When mist in the gas rises at a constant speed, then the mist eliminator works where vapor strikes the mesh surface filament and liquid start coalescing. After some time, liquid droplet size goes up and it gets isolated from the filament.
