Embodiment Construction

[0016] exist figure 1 , a cyclone separator used to separate sticky particles from a gas stream is shown in three dimensions. It comprises a cylindrical outer wall 1 , an inlet conduit 3 and an outlet 5 for particles. In addition, a dip tube 2 is provided, which is arranged eccentrically in the direction of the inlet conduit 3 . The inlet duct 3 is arranged with an inclination towards the particle outlet 5 in the flow direction, wherein the inclination α lies in the range between 10° and 45°.

Abstract

At its end in direction of the particle outlet (5), the flow cross-section of the inlet duct (3) has a triangular expansion Q which laterally is formed by the cylindrical outer wall (1) and by an outer boundary (4). The outer angle of inclination [beta] between the outer boundary (4) and the vertical, proceeding from the end of the inlet duct (3), extends from 30 DEG to 0 DEG in flow direction of the gas streams. Subject-matter of the invention furthermore is the use of the cyclone for separating partly molten particles.

Description

technical field [0001] The present invention relates to a cyclone for separating sticky particles from a gas flow and to the use of the cyclone. Background technique [0002] Centrifugal separators in the form of cyclones are known. In gas purification, for example, they are used to separate solid particles contained in gases. The gases are put into a rotational movement due to their own flow velocity and the corresponding structural design of the cyclone separator. Centrifugal forces acting on the particles accelerate the particles radially outward. In this way they are separated from the air flow which is passed into the interior and discharged. However, when the gas to be purified contains sticky particles, it is disadvantageous if particle accretions occur inside the cyclone separator, which leads to a reduction in the separation efficiency of the cyclone separator. Great efforts have to be made to interrupt the gas cleaning in the cyclone separator and the cyclone s...
