Description

In this paper, effects of the number of the layers on the separation characteristics of the wire-mesh demister is described. The wire-mesh demister used here is constructed with galvanized iron wires 850μm in diameter, and is held perpendicular to the vertical upward flow of air laden with water droplets.<BR>Experiments have been made with mesh layers from one to four layers and for mean air velocity from 0.5 to 4.0 m/s. In the case of the vertical upward air flow, the water-film on the wire-mesh surface has important influences on the size distribution of water droplets, the separation efficiency and the pressure loss coefficient.<BR>Obtained separation performances are compared with the results predicted by theoretical analysis which has been presented before.
