Abstract
It has been reported by previous studies [1–7] that droplet size in a Pease-Anthony Venturi scrubber depends on the jet atomization conditions, such as jet velocity and gas velocity. The assumption of this paper is that actual collector-droplet size in a confined tube such as the Venturi scrubber also depends significantly on preferential droplet deposition on the tube walls, which remove preferentially droplets of a certain size from the core, modifying the mean droplet size of the remaining droplets. To account for this effect, the present study is focused on the experimental measurement of the liquid deposition on the walls of a Pease-Anthony Venturi scrubber and the droplet size remaining in the core. The experiments were carried out varying jet penetration and the number of the injection orifices. A correlation, using dimensionless numbers, was proposed to quantify the influence of each experimental condition. The results showed that liquid deposition has a significant influence in actual collector-droplet size inside a Venturi scrubber.
