Apparatus for processing flushing liquor from coke ovens

DETAILED DESCRIPTION The present invention processes flushing liquor by a construction and arrangement of an apparatus that occupies far less floor space than known apparatus.
In accordance with the invention, the decanting vessel is of a basic vertical design of circular cross section.
This design permits economies of material requirements per unit volume of processed liquor as compared to conventional low, flat decanter tanks of rectangular cross section.
System heat loss is reduced because the vessel has less exposed surface per unit volume of liquor contained in the vessel.
The vertical circular vessels permits a reduction in yard space requirements when compared to other vessels performing the same function, yet the invention provides for the employment of the proven basic decanting phenomena while retaining available system hydraulic heads for flows of the existing products.
A further feature of the invention includes an internal tar scraper which is moved by magnets mounted external to the vessel shell.
Magnets are fixed on a carriage which negotiates a circular track.
As the magnets move, the internal scraper bar follows.
