Study of eco-friendly static gas-solid centrifugal separator

Gas-solid separation is a common process in many industries, including transport and power engineering. A static centrifugal multivortex device has been developed for effective separating fine particles from gas streams. The work aims to numerically study the efficiency and pressure drop of the separator. It was found that a choice of the turbulence model does not affect the pressure drop. The efficiency of the static centrifugal separator is 64.3% at the input gas velocity of 7 m/s. The sloped blades located above the apertures made in the internal pipe results in the improvement of separation efficiency. Moreover, changing the slope of the blades does not affect the efficiency of the separator. The hydraulic resistance coefficient of the developed device is on average 20.6, with a Reynolds number from 11400 to 38000. The low pressure drop provides reduced energy cost, which promotes decarbonization efforts.
