Goal. Stated problem in scientific article could be solved by computer modeling of gas stream motion in working area using CFD - programs. Knowledge about structure of gas stream and the trajectory of motion of dust particles afford us to evaluate the efficiency of its work and optimize the design of apparatus. Significance of work consists in evaluation of efficiency of work of cleaning apparatus using CFD - programs. Experiments that is conducted using CFD - programs considerably accelerate the process of researches and are cheaper. Methodology consists on determining the trajectory of motion of certain parts of one fraction from the conditions of entrance in an apparatus. Particles, which trajectory reached the walls of cylindrical or conical part of apparatus corps, is considered to be “captured”. The particles, which trajectory reached the top butt of inlet nozzle, is considered to be “carried”. The ratio of the “captured” and “carried” particles determines the factious efficiency of apparatus. Results. The article optimizes design of the cyclone with a spiral directing apparatus and determines the efficiency of its work. Scientific novelty. There is suggested for first time to determine the efficiency of work of cleaning apparatus by CFD - programs, using the dependence of the trajectories of motion of dust particles from the conditions of entrance in an apparatus. Practical significance. Using CFD - programs afford us to predict cleaning efficiency and optimize the design of cleaning apparatus of the dry cleaning. The obtained results make it possible to create of high-efficiency cleaning equipment.
