Abstract

Dust emission gas cleaning is a crucial factor for many industries. The paper proposes a separator with the arc-shaped elements to clean dusty gas from solid particles. The study aims to examine how the distance between rows of arc-shaped elements affects separator efficiency and pressure drop, using numerical methods. In simulations, the inlet velocity of the gas flow varied from 0.5 to 5 m/s and the particle size was 10 to 170 μm. It was found that the change in the distance between the rows of the arc elements in the device leads to the formation of different streams. The results show that increasing the distance between the rows of the arc results in a decrease in the separator efficiency, since the particles during separation from the dusty gas due to centrifugal forces fly into the space between the elements, where they are inversed by the flow again. In this case, the pressure drop decreases. The maximum efficiency of particle separation by the developed device (95.4%) is achieved at a distance between rows of arc elements of 0.75. Pressure loss in the separator ranges from 16 to 1862 Pa at an inlet gas velocity of 0.5 to 5 m/s.
