Droplet Dispersion Angle Measurements on a Pease-antony Venturi Scrubber
A Pease-Anthony Venturi scrubber is a gas cleaning device that uses liquid, injected in the equipment as jets, to remove contaminants from the gas. The liquid jet is atomized into droplets, which are dispersed throughout the equipment due to the turbulence. The performance of the scrubber is affected by the spatial distribution of the droplets. Although CFD models have been used to predict the ...

In this article we have made an attempt to survey some results on performance of jet ejector. The literature is also reviewed to pursue further work in this area. Key wordsHEVS, EVS, jet ejector, performance of venture scrubber, characteristics of jet ejector, efficiency
متن کاملComparative Study on One-Dimensional Models for Particle Collection Efficiency of a Venturi Scrubber
A wet type filtered containment venting system of a nuclear power plant uses venturi scrubbers submerged in a water pool to enhance the efficiency of collecting particulate aerosols from a gas effluent discharged from a containment after severe accidents. This paper describes a comparative study of three typical one-dimensional semi-empirical models on their predictive capability for particle c...
متن کاملParticle collection efficiency in a venturi scrubber: comparison of experiments with theory.
Particle collection efficiencies in 23 size intervals covering a diameter range of 0.32-2.8 pm were measured for venturi scrubbers with throat diameters of 3.2,5.4, and 7.6 cm. Each scrubber was operated with four types of liquid injection, throat gas velocities from 21 to 160 m/s, and liquid-to-gas volume ratios from 0.000 19 to 0.0043. Results were compared to three widely used theoretical mo...
متن کاملPerformance estimation of a Venturi scrubber using a computational model for capturing dust particles with liquid spray.
A Venturi scrubber has dispersed three-phase flow of gas, dust, and liquid. Atomization of a liquid jet and interaction between the phases has a large effect on the performance of Venturi scrubbers. In this study, a computational model for the interactive three-phase flow in a Venturi scrubber has been developed to estimate pressure drop and collection efficiency. The Eulerian-Lagrangian method...
