Purpose. To increase the level of environmental safety of enterprises by improving the quality of air purification from polydisperse dust in two-circuit closed systems, in particular, to obtain the basic design relations for the engineering calculation of such systems. Methodology. The aim of the study was realised by mathematical and numerical modelling of hydrodynamic processes in the elements of a closed double-circuit purification system. Findings. A methodology for hydraulic calculation of a closed two-circuit cleaning system was proposed by drawing up a pressure balance of individual circuits, and a dependence for the complex coefficient of hydraulic losses of the collection-return apparatus was determined. Originality. The hydraulic calculation of two-circuit closed cleaning systems is proposed to be carried out by compiling the pressure balance of individual circuits. To calculate a specific element of the system – the collection-return apparatus – the concept of a complex hydraulic loss coefficient is introduced, which takes into account both local pressure losses and losses along the length, and also indirectly reflects the effect of flow swirl on the hydraulic resistance of this element. For the complex coefficient of hydraulic losses, the quantitative results necessary for engineering calculations were obtained by numerical modelling of hydrodynamic processes of the swirling flow in an annular pressure channel. Practical value. The obtained results make it possible to design two-circuit closed cleaning systems for different production conditions, which, in turn, makes it possible to replace typical and inefficient direct-flow systems with a system in which the efficiency of polydisperse dust capture is significantly increased due to separate cleaning.

“…From the data V0 and E0, it can be calculated that the application voltage was the voltage that could operate the EP. The last data obtained was the electric field strength after particles were present (Ep) based on Equation 3 between the application voltage (V0) and the distance between the wire and plate in m units (Muzafarov et al, 2020).…”

The current global environmental trend is that the world has agreed to go towards net zero emissions. Consequently, waste-producing-industries must comply with these provisions to achieve the mission of sustainable development and green production, including cement industry. This study aims to investigate the factors that affect the performance of the Electrostatic Precipitator (EP) as a dust collector in grinding cement raw materials. The method used was measuring the static-dynamic pressure at the poking hole closest to the EP inlet, measuring EP efficiency using the Matts-Ohnfeldt equation based on secondary data obtained from the Crane Information Management System (CIMS), and calculating the corona power to determine how strong the ion space is created between the discharge electrode and collecting electrode and determine the critical voltage and application voltage needed to generate the corona. The observations and calculations show that several factors can affect EP performance, such as inlet temperature gas discharge, concentration of dust from the chimney, and maximum concentration of chimney outlet. The maximum temperature gas discharge that EP can accept is 105°C. The maximum concentration of chimney outlet dust is 50 mg/Nm3 and maximum CO concentration is 2000 mg/m3.
