Basic: vapor-liquid filter, also known as the froth Mo net, mist net, in addition to the the demister wire mesh, gas-liquid filter, a crochet weave woven screen, usually with stainless steel wire diameter φ0.15mm ~ φ0.28mm between the width of the net are: 100mm, 150mm, 300mm, 400mm, 500mm, 550mm, 600mm; mesh size: 3X4mm, 4x5mm, 5x6mm, 5X10mm several grooved woven into the mesh surface pressure on the 20 to 45 degree angle 2 ~ 7mm deep corrugations. The vapor-liquid filters are widely used: the froth in the petroleum, chemical industry, light industry, medicine, metallurgy, aerospace, shipbuilding, environmental protection engineering, distillation, evaporation, absorption process, the gas-liquid separator, the gas-water separator, mechanical equipment oil and gas separation. On the tower body made in addition to Mo for broken bubbles, the bubble restore the droplets to ensure that the mass transfer efficiency, reduce the loss of valuable materials to reduce the tower body or container volume, improved equipment working conditions.
