METHOD AND DEVICE FOR CLEANING WASTEWATER FROM A COKE QUENCHING TOWER WITH SHORTENED CATCH BASIN DWELL TIME

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.
