The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor is provided with outlets in the lower part thereof and is arranged in a separating tank. At least one suspension inlet extends eccentrically into said reactor. The supplied suspension is guided into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor via the suspension inlet. A circular flow is thus created which drains off from the flocculation reactor downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank. In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards. One advantage of the invention is that said flow of the mixture has to travel a longer way to the outlets in the area of the wall of the tank due to the tangential flow component. The solid matter can be separated more effectively by virtue of the longer travel path or the longer presence in the separating tank.
A device for the chemical and physical separation of solid matter, from a suspension, comprising an essentially cylindrical separating tank, in which centrally a rotationally symmetrical flocculation/flow reactor is provided into which at least one suspension inlet directs flow eccentrically, said suspension inlet conducting the supplied suspension into the flocculation reactor and thereby creating a circular flow, wherein the suspension inlet is provided in an upper area of the flocculation reactor and the circular flow drains off from the flocculation reactor downward with tangential and radial components over an outer periphery into circularly arranged distribution cells configured and dimensioned to reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank.
A device for separation of solid matter from a suspension, comprising:
