Abstract: A wet quenching tower for quenching hot coke, including a quenching chamber, having a quenching spray device above the quenching chamber for dispensing quenching water, having a flue placed on the quenching chamber, and having at least one separating device which is arranged horizontally or at a slanted angle relative to the vertical, which can be vertically permeated, and which has a plurality of lamellae. Each of the lamellae has a non-branching cross-section, flow paths being formed between each two adjacent lamellae. The flow paths formed between each two lamellae change direction multiple times and correspondingly have a serpentine shape. A method for quenching coke using the aforementioned wet quenching tower is also disclosed.

Abstract: A device and a method for cleaning emission protection installations in coke quenching towers. The emission protection installations are fixed to a support structure in the chimney of the coke quenching tower. A liquid is sprayed onto the emission protection installations by nozzles for cleaning purposes. The nozzles are arranged on at least one movable element.

Abstract: The present disclosure relates to a process and apparatus for the purification of waste water from a coke quenching tower with reduced residence time in a collecting basin. In the process and apparatus of the present disclosure, water is used for the quenching of hot coke, and the quench water is collected in a collecting basin which is sized such that it is adequate for few quenching operations. The quench water is fed to a downstream hydrodynamic purification device without requiring any additional settling operation. In the purification device, the solids are separated from the quench water by a mechanical separation processes so as to allow a space-saving arrangement of the water collecting basin without a settling basin.
