Study of vortex pneumatic sprayer for liquid disinfection

Abstract

The production of high-quality livestock products can be achieved by upgrading livestock breeds and complying with zootechnical requirements of ensuring sanitary well-being in animal houses. Different ways are applied to gain the proper clean condition of livestock houses and equipment, disinfection preparations for working surfaces. Besides, non-compliance with the requirements for operating devices and standards for disinfectant consumption leads to increased antimicrobial resistance of microorganisms [1]. The efficiency of disinfection depends mainly on the technical capabilities of the units, mainly on the spray devices. Many researchers solve complex problems by optimizing spray devices' design and technological parameters to improve their spray quality [2]. The authors developed a vortex pneumatic sprayer for liquids for the disinfection process. The dispersion composition of disinfectant liquid aerosols was obtained in different operating regimes of the proposed sprayer design. Based on experimental data, dependencies of the influence working pressures of disinfectant liquid and compressed air in their supply channels on the dispersion were obtained. The flow rates of the vortex pneumatic sprayer during its operation in various regimes were determined. Dependencies of disinfectant liquid flow rate through the sprayer were constructed at different pressure ratios in supply channels of working fluids (disinfectant liquid and compressed air) and the angle between them. Optimal design parameters of the vortex pneumatic sprayer for aerosol disinfection of livestock houses and equipment were determined.
