The article considers the problem of improving efficiency for capturing solid particles in the production of silicon dioxide. The authors propose a separator with inclined double-T elements. The operating principle of the device is described. It is shown that particles are captured from gas due to centrifugal forces when they pass through elements. The main parameters affecting the collection efficiency of the separator are the inlet gas velocity, which determines the centrifugal force of the swirls, the particle density, and the diameter of the particles determining the inertial knocking out of the structured flow. Numerical simulations have shown the device’s efficiency with inclined double-T elements in collecting fumed silica solids of 1 to 15 μm in size, a density of 2000 to 3000 kg/m 3 , and the inlet velocity of 3 to 10 m/s changes from 20.8 to 100%. Pressure loss of separator with inclined double-T elements is 168 to 1880 Pa at inlet gas velocity from 3 to 10 m/s.
