Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Simulation of the Technological Process of Liquid Spraying in a Slot Atomizer for the Deposition of Industrial Dust O.V. UDARTSEVA The article presents an approach to modeling the technological process of spraying liquid for cleaning industrial emissions. The input parameters are the process pressure, the velocity of the liquid, the dispersion of the droplets formed, and the design of the upgraded spray device. A new method and device is proposed in which liquid is sprayed twice due to a diffuser hole formed by two conical surfaces. The results of the study show that the proposed mathematical model refl ects the relationship between the pressure of the technological process created by the upgraded device and the size of the sprayed droplets necessary for effective cleaning of industrial dust. Verification of the developed model of the technological process of liquid spraying was carried out for an upgraded spray device, which made it possible to establish the effect of pressure in the system on the diameter of the droplets formed.
