Mist Eliminator Filter Use in Bio-Scrubber or Air Handling Systems

1. Mist Eliminator Filter Description

Demister Pad

Demister Pad, also called mist pad, wire mesh demister, mesh mist eliminator, catching mist, mist eliminator. Demister Pads are woven with multi-layer knitted mesh in different densities. It is used in gas entrained mist separation column to guarantee the filtering efficiency.

Demister pad is porous blankets of metal wire or plastic knitted mesh, designed and constructed for the efficient, economical removal of entrained liquid droplets from vapor streams.

Demister pad Mesh is normally knit from wires ranging in diameter from .0035” to .0200”. In special applications, Metal Textiles has knit wires ranging in diameter from .0005” to .0350”. These wires can be round or flat such as those used in Metal Textiles copper gauze for cleaning and in air-filtration applications where large surface areas of wire are needed. A round wire when flattened has approximately twice as much surface area.

Infiltration applications, wire diameter is perhaps the most important design variable. It directly affects flow, dirt holding
capacity, pressure drop, and cost. In general, larger diameter wire allows for higher flow but provides lower dirt holding
capacity. Also, a larger diameter wire is less expensive. Therefore, a balance must be struck between using a higher density filter of higher cost fine wire or a lesser density filter using lower-cost heavy wire.

Material Of Construction

Demister Mesh also named knitted wire mesh, gas-liquid mesh, foam net, wire mesh demister, knitting mesh, demister mesh pad. It is one of using crocheted weaving woven wire mesh. Products are mainly used for gas-liquid separation and despumate in oil; chemical industry, automobile industry, environmental protection. It can also be used electromagnetic shielding in construction engineering.

Demister Mesh can be made of stainless steel wire, copper wire, galvanized wire, PTFE wire, flat galvanized steel wire, etc.

2. Mist Eliminator Filter Features

Knitted metal has distinct advantages over most competitive materials. Because each loop acts as a small spring when subjected to tensile or compressive stress, knitted metal has an inherent resiliency. If it’s not distorted beyond its yield point, the material will resume its original shape when the stress is removed. Even when it’s compressed into a special shape, a high degree of resiliency is retained. Varying the knitted structure, wire diameter, wire material and forming pressure used to create the part can control this characteristic.

Knitted metal also provides high mechanical damping characteristics and non-linear spring rates. Vibration and mechanical shock can be effectively controlled to eliminate the violent resonant conditions and provide ample protection from dynamic overloads.

In compressed form, knitted metal can handle shock loadings up to the yield strength of the material itself. The load may be
applied from any direction—up, down or in from all sides. Our application engineers have the experience to determine the optimum density of compressed units within the range of 10% to 70%. This is important in applications such as liquid filtration and noise attenuation where flow resistance is critical. When compressed, layered, calendared or wound knitted metal presents a “torturous” path to liquids or gasses flowing through it. This increases filtration capability and particle retention capacity.

Among the most important property of knitted mesh units is the material itself. By careful selection of the material or
combinations of materials, Metal Textiles can custom engineer solutions best suited for our customer’s application—be it
corrosive, ultra-high or cryogenic temperature, high pressure, radioactive, dirty, oily or other extreme conditions.
