Abstract
A wire mesh mist collector pad having multiple density zones, the zones being arranged other than to provide a constantly increasing density gradient, provides a reduced pressure drop and increased capacity. For example, the pad can include at least three zones with the zones arranged so that the density gradient in the direction of gas flow through the pad varies from low to high to low or from high to low to high.
Claims14
A knitted wire mesh mist collector pad having a low average density and comprising:
- at least three zones of flattened and crimped wire mesh tube, at least two of said zones having densities that are different from one another as a result of comprising meshes of different densities, and the zones arranged so that the density gradient in the direction of gas flow through the pad varies from low to high to low or from high to low to high.
A knitted wire mesh mist collector pad having a low average density and comprising at least four zones of flattened and crimped wire mesh tube, at least two of the zones having densities that are different from one another, the zones being arranged in the pad so as to produce a pattern that alternates between higher and lower density zones.
A method for making a mist collector pad having a low average density comprising:
- providing predetermined cut lengths of first and second flattened, crimped, knitted wire mesh tubes having different densities from each other;
- layering one or more of said predefined cut lengths of said first tubes to define a first zone;
- layering one or more of said predefined cut lengths of said second tubes to define a second zone;
- layering one or more predefined lengths of said first tubes or of third tubes having a density different than said first and second tubes to define a third zone;
- and securing said first, second, and third zones in a grid suitable for installing in a process gas stream, wherein the respective densities of the meshes in the respective first, second, and third zones in the direction of the gas flow are lower, higher, and lower, or higher, lower, and higher.
