700Y Wire Gauze 0.15mm Metal Structured Packing

①The data are based on 0.12mm wire, stainless steel material. Applicable temperature (-200—400)℃. 0.15mm and 0.17mm wire are also available.

②Metal wire mesh corrugated packing is suitable for clean gas-liquid system without solid particles or suspended solids or not easy to self-assemble.

Geometric parameters of wire gauze structured packing layer

Corrugated packing is widely used in structured packing. Its geometric parameters are generally characterized by the geometric structure and characteristic size of the corrugated sheet, which is the monomer of the packing layer.

① Peak height h
② Wave distance 2B
③ Tooth apex angle ξ
④ Inclination angle of corrugation
Generally, the B ≈ h and ξ of corrugated packing are 75 - 90, 78 - 81, φ = 45 (Y type), 30 (X type).
⑤ The hydraulic (or equivalent) diameter DH is used to characterize the size of the fluid channel of the regular packing unit, which can be derived according to the rules of fluid mechanics
DH=
⑥ Specific surface area. The sum of geometric surface area of filler in unit volume packing layer, unit m2 / m3.
Alpha =
⑦ Porosity ε is the volume of void in a unit volume of filler layer, or the fraction of void volume (free space) in the volume of filler layer. ε = 1 - α δ / 2, where δ is the thickness of corrugated plate (or net), unit: M.
⑧ Bulk density ρ P, the mass (or weight) of filler per cubic meter of packing layer, unit: kg / m3.
ρ P = (1 - ε) ρ m, where ρ m is the density of filler material, kg / m3.
