Wire Mesh Demister

Wire Mesh Demister (also is known as mist eliminator, demister pads) is a highly efficient gas-liquid separation device.

Working principle of demister pad

When the gas with mist rises at a constant speed and passes through the wire mesh, the rising mist will collided with the mesh filament and attached to the surface filament due to the inertia effect. The mist will be diffuse on the filament surface and the droplet will follow along the filaments of the two wire intersection. The droplet will grow bigger and isolate from the filament until the droplets gravity exceeding gas rising force and liquid surface tension force while there is little gas passing through the demister pad.

Separate the gas in the droplets can improve the operating condition, optimize process indicators, reduce corrosion of the equipment, extend equipment life, increase the amount of processing and recovery of valuable materials, protect the environment, and decrease air pollution.

Features of demister pad

• Simple structure.
• Lightweight and easy to transport.
• High porosity, less pressure drops.
• Large surface area and high separating efficiency.
• Easy to install, operate and maintain.
• Durable and long service life.
• Corrosion and rust resistance.

Maintenance of demister pad

After using for a long time, the demister pad will clog or prone to flooding and the pressure drop will increase. All these because of the particles in the gas blocks the demister pad. So you need maintain the demister pad properly and regularly.

Maintenance method: clean the demister pad. As we all know, the dilute acid on the demister pad will shorten the service life of demister pad, so we should place the demister pad in the natural state or under the sunlight
