Mesh mist eliminators are expensive and can remove 5 μm droplets, but have a large pressure drop (about 250 Pa). As long as the operating gas speed and other conditions are properly selected, the defoaming efficiency of the gas can reach more than 99% after passing through the wire mesh mist eliminator, and the purpose of complete removal of mist can be achieved. Wire mesh mist eliminators are mainly used for gas-liquid separation, and can also be used for gas separation for air filters.
