The production of high-quality livestock products is achieved not only by breeding productive livestock breeds, but also by observing zootechnical requirements and ensuring sanitary well-being in livestock buildings. To maintain the proper sanitary condition of livestock buildings, modern technologies, technical means and preparations for disinfecting surfaces are used, and non-compliance with the requirements for the operation of technical means and the consumption rates of disinfectant liquids leads to an increase in the resistance of microorganisms to antimicrobial drugs. The effectiveness of disinfection largely depends on the technical capabilities of disinfection units, and to a greater extent on spray devices. Many researchers solve complex problems of optimizing the design and technological parameters of spray devices, thereby improving their spray quality. In this regard, a vortex pneumatic liquid sprayer has been developed to perform various technologies and disinfection modes. The dispersed composition of aerosols of disinfecting liquids was obtained under various operating modes by the proposed design of the sprayer. Based on the experimental data, graphical dependencies are constructed that affect the degree of dispersion of the working pressures of the disinfectant liquid and compressed air in the channels of their supply. The values of flow rates of a vortex pneumatic atomizer during its operation in various modes are obtained. Graphic dependences of the disinfectant liquid flow rate through the sprayer are plotted at different pressure ratios in the media supply channels (disinfectant liquid and compressed air) and the angles between them. Based on the obtained technical characteristics, the rational design parameters of the new design of the vortex pneumatic atomizer were determined, namely, the angle between the pneumatic and liquid inlet channels α=90o, the diameter of the outlet d=2.0 mm.
