The invention relates to a method for cleaning wastewater from a coke quenching tower with shortened catch basin dwell time, in which method water is used to quench hot coke and the quenching water is captured in a catch basin, which is dimensioned so as to suffice for a few quenching processes, and, without a further settling process, the quenching water reaches a downstream hydrodynamic cleaning device, in which the solid material is separated from the quenching water by mechanical separation methods, so that a space-saving arrangement of the catch basin without a settling device is possible. The invention also relates to an arrangement that consists of a quenching tower, a quenching water channel for transferring the excess quenching water to a catch basin, a catch basin, a hydrocyclone, a gap filter and a centrifuge, which is used for separating the solid material and the quenching water. |
