Cyclone separator with two separating zones and static guide mechanisms. As a result of an immersion tube column (5, 6, 7), which surrounds the cyclone axis (1) over the entire separating zone height h, which is arranged in the vortex core of the conventional cyclone and passes through the conventional solids collecting container (2a), both the outer swirling flow in the outer separator zone (3a) and also an inner swirling flow concentrated in the immersion tube column in the second separating zone (3b) is stabilized in combination with a return flow-free solids discharge device (4), so that in the case of an intense swirl a following separating process takes place with axial return flows (18) from swirl promoter (17) into a second solids collecting container (2b). The components of the immersion tube column are the conventional immersion tube (5), a downwardly located slotted slit immersion tube (6) in the axial extension thereof and a downwardly following central immersion tube (7), to which is flanged the second solids collecting container (2 b). The sucking slit immersion tube (6) is used as the inflow guide mechanism for the swirl promoter (17) and has four parallel-wall, curved intake channels (10) uniformly distributed about the immersion tube circumference with in each case a straight leading edge (9), which exert an accelerating action on the flow. The recovery of the kinetic energy of the swirling flow is brought about by an outflow spiral (8) above the cyclone cover (13).
Cyclone separator comprising two separating zones (3a, 3b) and static guide mechanisms for improving the separating capacity with respect to very finely dispersed particles from flowing gases and reducing the pressure drop or for influencing the field of flow of a centrifugal force separator with a tangential, spiral or helical intake channel (11), including an upper cylindrical (12a) and a lower conical (12b) cyclone casing, a solids collecting container (2a) located below it, whilst in the cylindrical separating zone, a cylindrical immersion tube (5) for removing the pure gas flow projects centrally from above into the cyclone casing, including an immersion tube column comprising a series connection of the immersion tube (5), a slotted slit immersion tube (6) with a helical or straight slit channel and a central immersion tube (7), by which the cyclone axis (1) is surrounded over the entire separating zone height h, is located in the cylindrical interface of the cyclone separator, passes through the solid collecting container (2a) and is connected in gas tight manner to a second solids collecting container (2b) located below the first container, means for enabling the three partial immersion tubes (5, 6, 7) to be connected in reciprocally open manner and the slit immersion tube (6) is the sole sucking partial immersion tube.
