FIELD: agriculture.SUBSTANCE: gas purification device contains a centrifugal separator with a centrifugal rotor for separation of particles from gas and the actuating unit for rotation of a centrifugal rotor around a rotation axis. The actuating unit contains the active turbine attached to a centrifugal rotor with a possibility of its driving, and a nozzle for the fluid medium under pressure. The active turbine is implemented with blades for reception of the fluid medium flow under pressure from the nozzle directed towards the blades which are implemented so that the direction of the fluid medium flow is reversed along the blade height. The blade height is 2-3 times greater than the diameter of the nozzle bore.EFFECT: increase of efficiency of utilisation of energy for driving of a centrifugal rotor at high speeds of rotation at the same flow of the fluid medium under pressure.14 cl, 4 dwg |
