Savchenko-Pererva M. Improvement of vortex devices for the intensification of the process of trapping dust products in the food industry

Thesis is devoted to the study of the process of separating solid particles from air in the vortex devices with counter swirling flows (ACSF) with a cylindrical separation chamber that is designed to separate gas and liquid heterogeneous mixtures, drying granular and bulk materials, drying of inert solids pastes and concentrated suspensions, granulating products and finely dispersed materials: organic dyes, pigments, fertilizers, food products, pharmaceuticals, high-temperature processes of polydisperse systems and to trapping a significant range of dust products in the chemical, construction and food industries, is keeping the quality for later use. Defined parameter, which hindered the movement of the primary flow in to separation space of the apparatus and thereby reduced the efficiency of purification. Due to the design changes to the standard models, increased input momentum in the primary stream. The character of the currents flows and their interaction in a reasonable physical model of the improved ACSF. The dependences of the fields of velocity and hydraulic losses. Experimentally confirmed the improvement of the apparatus with counter swirling flows, in improving the efficiency by 5%. Defined the diapason of capture from solids of dust-Laden air ACSF after improvements. Proposed and protected by patents of Ukraine for utility model with a cylindrical separation chamber, which were tested at industrial food processors. Conducted a feasibility study of the use of improved equipment with counter swirling flows that showed significant economic benefits when implementing them in food production.
