Wave Shape Wire Mesh Demister / Oblique Type Demister Pad Higher Capacity
1. Wave Shape Wire Mesh Demister Introduction
There are many types of mesh pad demisters, including flat type, oblique type, etc.. Usually the mesh pad thickness for flat type demister is 100mm or 150mm. With simple structure, it suits for low velocity, low mist rate gas flow. Re-entrainment easily happen when the gas velocity is too high. While the oblique type (sometimes also shown as wave shape demister) has flow guiding effect on the captured liquid droplet, leaving less liquid droplets on the downside of the mesh pad. So the oblique type demister has less resistance to the passing gas flow, and is a little harder to cause re-entrainment. It allows somehow higher velocity and mist content.

4. Wave Shape Wire Mesh Demister Applications:
Wire demisters of various styles and materials are available for all applications. By selecting the style based on the application, the wire demister fully demonstrates its performance matching the work conditions.
Mesh Density kg/m3 | Wire Dia. Mm | Specific Area m2/m3 | Void Fraction % | |
| Type 2 | 144 | 0.23 | 316 | 98.2 |
This demister is most appropriate for general purposes. When data such as the amount of flying and accompanying liquid and the size of water drops are clear, the effect is excellent. The demister is highly efficient even when, to a certain extent, the air flow is changed. A 100mm thick demister is used for distillation tower, evaporator and scrapper but the thickness can be increased to 150mm for higher efficiency.
Mesh Density kg/m3 | Wire Dia. Mm | Specific Area m2/m3 | Void Fraction % | |
| Type 3 | 192 | 0.23 | 421 | 97.6 |
Though the demister is deemed the standard type because it is used in many fields, this model is strong and highly efficient. The demister is used in places where it is necessary to reduce accompanying airborne droplets to a minimum.
The demister safely functions because the design adapts to changes in gas or fluid flow rate. Generally, the 100mm mesh pad is used, but the mesh pad of greater thickness is used where the flow rate changes extensively, offering increased production.
