Abstract:
Purpose. Increasing the level of environmental safety of enterprises with direct-flow aspiration systems by improving the quality of air purification from polydisperse dust in systems with standard capture equipment by isolating the flow from the environment.
Methodology. The purpose of the research was realized by developing a closed two-circuit purification system and assessing its efficiency by the mathematical modeling of the dedusting process of a particular polydisperse flow.
Findings. A scheme of a two-circuit closed system of air purification, in which the polydisperse dust is initially divided by fractional sign, is proposed. The coarse dust flow is cleaned in the main circuit and, with a minimum mass of yield, returns to the premise in the area of the collecting equipment operation. The fine dust flow is cleaned due to the repeated passage through the circulation circuit capture equipment. A method of calculation of indicators of the proposed system is developed.
Originality. The issue of increasing the level of environmental safety of small industrial enterprises and industries, where there is a need to clean air from dust, is proposed to be solved by replacing the traditional direct-flow system with a two-circuit closed one. The ecological effect is achieved by separate purification of dust particles with different fractional composition and due to the complete isolation of the system from the environment. The obtained results of mathematical modeling allowed estimating the values of the indicators of the effectiveness of the elements of the system and the nature of their changes during the work.
Practical value. The proposed system makes it possible, without significant investment into purchasing expensive high-efficiency collecting equipment, to modernize traditional direct-flow systems for cleaning dust polluted air and at the same time to achieve a significant ecological effect through almost complete elimination of emissions into the atmosphere.
