2. demister  Introduction: silk screen defoaming device is a kind of efficient gas liquid separation device. It has simple structure, big porosity and small pressure drop, large contact surface area, high defoaming efficiency, light weight, installation, operation, maintenance is convenient. Screen also known as wire mesh mist eliminator defoaming device is mainly used for separating diameter greater than 3 ~ 5 mu mu m m droplets. When with the gas entrainment in a certain speed rise, through the grid in the middle of the filter wire mesh, due to the effect of inertia of the entrainment to rise, makes the entrainment collisions with filaments and adhesion on the surface of filaments. Filaments on the surface of the entrainment further proliferation and entrainment itself gravity settling, the entrainment form a larger droplets along the filaments mixed flow to it. Because of filaments wettability, surface tension of liquid and filaments capillary effect, make the droplets is bigger and bigger, until its own gravity over rising gas buoyancy and resultant force, the surface tension of liquid is separated to fall. As long as chooses proper operating gas velocity conditions, gas through the screen after defoaming device, the defoaming efficiency can reach above 99%, can achieve the purpose of completely removing entrainment.
3.  demister USES: in addition to the foam used in gas separation tower entrained droplets, to ensure mass transfer efficiency, reduce the value of material loss and improve the operation of the compressor after, more commonly defoaming device must be set up in the tower. Can effectively remove 3 -- 5 um droplets, tray if setting between defoaming machine, not only can ensure the mass transfer efficiency of tower tray, also can reduce the plate spacing. So the silk screen defoaming device is mainly used for gas and liquid separation. Also for the air filter is used for gas separation. In addition, the screen also can be used as instrument of buffer in instrument industry, in order to prevent interference of waves of electromagnetic shielding, etc.
