Investigation of the influence of mass productivity on the quality of the centrifugal separator of bioconversion products

The priority directions of the development of the agro-industrial complex is the creation of new equipment and the improvement of existing technological equipment and bioconversion technologies. Separation of the grown biomass from related materials is one of the main technological operations for obtaining the finished product. Therefore, the development of a bioconversion product separator is an urgent task. One of the promising directions of increasing the efficiency of centrifugal separators is the behavior of the dispersed flow. The behavior of the dispersed flow in separators is determined by a variety of design and technological parameters, such as the trajectory of the liquid particle, the axial instantaneous velocity of the liquid particle in the working chamber, the radial instantaneous velocity of the liquid particle in the working chamber, the tangential instantaneous velocity of the liquid particle in the working chamber. The kinematics of the flow of particles of a solid fraction of the process material of a centrifugal separator with a tangential arrangement of the inlet pipe and the influence of mass productivity on the quality of the separator of bioconversion products are investigated in the work. To describe a hydrodynamics flow in a physical and mathematical way, the Lagrangian Discrete Phase Model (DPM) was used as a model of technological material using a mathematical model based on the system of Navier-Stokes equations averaged by Rey-nolds. In the process of studying the kinematics of the flow, the package of the universal software system of the finite element analysis method ANSYS Fluent was used. The trajectories of movement and isolines of axial, radial and tangential components of the particle flow velocities of the solid fraction of the process material of the centrifugal separator of bioconversion products at different mass productivity of the centrifugal separator are obtained. The choice of the mass productivity of the centrifugal separator for the specified research conditions is justified.
