Air washer type WH1
Mist separator WH1 with and without coagulator
Introduction
Type WH1 VAKUTEC mist separators are especially suitable when aerosols must be separated due to the demands of enviromental protection.
Use: Aerosol separating
Features: 2 mist separator partitions, coagulator optional
Size
The following descriptions apply to our mist separators types with sizes DN180 to DN1250 for air stream volumes of 1100 to 68800m3/h. VAKUTEC mist separators Type WH1 needed for a larger air stream volume require special planning and adaptation.
Construction
The mist separator is constructed equipped with a quick locking mechanism. This makes maintenance or an inspection within the shortest time possible. The removal direction of the mist separator units, depending on the air direction being left, right or upwards is adapted to the local conditions accordingly.
Functioning
Type WH1 VAKUTEC mist separators operate on the principle of inertia. The aerosols found in the air are carried by the air stream and are dispersed onto the mist separator partitions. Due to the curvature of the profiles the moisture drops are driven along the innerface down into the catch pockets. In addition there are sharp edged ridges on the lamellae profiles to conduct away the remaining liquid.
As an option the mist separator unit can be equipped with a coagulator. The coagulator is positioned between the mist separator units so that the smallest drops are enlarged and then separated into the second mist separator. During transition the separator unit is intermittently sprayed for cleaning purposes with the help of double spray nozzles positioned upstream. The collected liquid passes through a siphon, which prevents unwanted air from being sucked in, and can then be subsequently further treated.
Materials
The materials used depend on the specific physical and chemical capacities. Preferably synthetic materials such as PVC,PP and PVDF are used.
In special cases stainless steel profiles as mist separator units can be fitted.
Technical details
With an even air stream flow the mist separator without a coagulator achieves a 99.9% separation of a minimum drop size of 15µ with a loss of pressure of 250Pa. With coagulator the separator efficiency rises on a drop size of 10µ with a pressure loss of 400Pa.
