Wire-mesh demister is a compact separating layer with a certain thickness weaved by metal wire. It is horizontally mounted in a container for removing liquid impurities from gas streams. When the gaseous stream vertically flows through the separating layer, liquid impurities are removed. It is recommended not to use demisters to process dirty medium as it may cause blocking, reducing the separating efficiency. Demisters can be vertically or horizontally mounted.

Production standard: GB150 or ASME VIII-1

Operating Principle:

When gas streams containing mist rise at a certain speed to pass through the wire mesh, the mist collides with the wires. Due to inertia and the effect of mist rising, a thin layer of liquid adheres to the wire surface. After mist spreading, condensing and settling on the wire surface, bigger liquid drops formed by continual mist flowing along the wire at the junction point of two wires. With more liquid adhering to the demister wires, coupled with surface tension of liquid and the capillary action of the wire, the liquid drops will coalesce and eventually drain by gravity. This happens when the droplet’s gravity exceeds the combined resultant force of the rising gas and surface tension of liquid. The separated gas would not contain any mist.

Demisting Efficiency:

Wire-mesh demister can remove 99 – 99.5% 2μm mist.

Typical Application:

Wire-mesh demister is widely applied in petroleum and chemical industries to remove liquid impurities such as condensate and lubricant from gas and recycle products for pollution control.
