Influence of Spiral Cutting on Mass Transfer of Venturi Jet
Salt spray,consisting of low-density distributed moist salt nuclei,poses signifi-cant corrosion risks to electrical and electronic equipment.Venturi scrubbers,serving as efficient and cost-effective gas-liquid mass transfer devices,offer a solution for salt spray removal.How-ever,the mass transfer performance of traditional Venturi scrubbers is heavily influenced by opera-tional conditions,necessitating further structural optimization.This study,based on computational fluid dynamics(CFD)simulations and experimental investigations,elucidates the variations in air intake and pressure drop of Venturi scrubbers under different water flow rates.To address the degra-dation of salt spray removal performance in Venturi scrubbers at high gas-liquid ratios,a novel Venturi scrubber coupled with a bubble generator structure is proposed.Numerical simulations re-veal that the new Venturi scrubber significantly reduces bubble size,enhances salt spray removal performance,and consequently mitigates the corrosive effects of salt spray on electrical and elec-tronic equipment.
