Description

Verfahren zur Ausnutzung der Wrasenwärme bei Brikettfabriken. Es ist bereits bekannt, den bei der Erzeugung von Braunkohlenbriketts entstehenden Wrasen in einem Riesellkühler mit Hilfe von Wasser zu entstauben und aus dem hierbei sich bildenden Schlammwasser durch Filtrieren den Kohlenschlamm und geklärtes Wasser zu gewinnen. Auf diese Weise könnte man die in dem Wrasen enthaltene Wärme wiedergewinnen, indem man sie auf Wasser überträgt und dieses den Trockeneinrichtungen zuführt. Es ist bisher aber noch nicht gelungen, solche Verfahren brauchbar zu machen, und zwar vor allem deswegen, weil die Trennung des Wassers von dem Kohlenstaub unter den gewöhnlichen Verhältnissen so langsam verläuft, daß auch große Absetzbehälter nicht ausreichen, während an ein Filtrieren überhaupt nicht gedacht werden kann. Vor allem haben aber die -bisherigen Verfahren der Berieselung mit Wasser den grundlegenden Nachteil, daß sich der Kohlenstaub aus dem Wrasen nicht vollständig ausscheiden läßt. Es wurde nun erkannt, daß dies deshalb nicht möglich war, weil nicht die richtige Temperatur gewählt wurde. Unterhalb einer gewissen Temperatur nämlich bleibt der bei Berieselung in dem erzeugten heißen Wasser verbliebene Kohlenschlamm teils in der Schwebe, teils schwimmt er im Wasser. Geht man aber über eine gewisse Temperatur hinaus, so sinkt er bei langsamer Wasserbewegung leicht zu Boden. Die entscheidende Temperatur liegt bei ungefähr 75' C, und zwar hat sich herausgestellt, daß bei Temperaturen über 75' die Oberflächenspannung des Braunkohlenstaubes aufgehoben wird, wodurch ein rasches Abscheiden eintritt.Process for utilizing the vapor heat in briquette factories. It is already known, the vapors resulting from the production of lignite briquettes to remove dust in a trickle cooler with the help of water and from here forming sludge water by filtering the coal sludge and clarified water to win. In this way the heat contained in the vapor could be recovered, by transferring them to water and feeding this to the drying facilities. So far, however, it has not yet been possible to make such processes useful, and mainly because the separation of the water from the coal dust under runs so slowly under normal conditions that even large sedimentation tanks not enough, while filtering cannot be thought of at all. Above all, however, the previous methods of sprinkling with water have the fundamental one Disadvantage that the coal dust is not completely eliminated from the vapor leaves. It was now recognized that this was not possible because it was not the right one Temperature has been selected. The remains below a certain temperature some of the coal sludge remaining in the hot water produced when sprinkled the levitation, sometimes it swims in the water. But if you go above a certain temperature it sinks slightly to the bottom when the water moves slowly. The decisive one The temperature is about 75 ° C, and it has been found that at temperatures over 75 'the surface tension of the lignite dust is canceled, whereby rapid deposition occurs.

Das den Gegenstand der Erfindung bildende Verfahren besteht also darin, daß man den Wrasen mit kaltem Wasser im Gegenstrom in Berührung bringt und die Berieselung so durchführt, daß die Temperatur während dieses Vorganges über 75' ansteigt. Zweckmäßigerweise führt man das Verfahren in einem Raschigturm aus, von wo das heiße Wasser langsam durch Klärbecken geführt wird, worin es den Schlamm. rasch ausfallen läßt.The method forming the subject of the invention thus consists in that the vapor is brought into contact with cold water in countercurrent and the sprinkling carried out so that the temperature rises over 75 'during this process. Appropriately the process is carried out in a Raschig tower, from where the hot water is slowly released is passed through clarifiers, in which there is the sludge. can fail quickly.

Zur Ausführung des Verfahrens kann man sich jedes Kühlers bedienen, beispielsweise eines Berieselungskühlers oder eines Oberflächenkühlersi. Es lassen sich hierfür im einzelnen keine Regeln angeben, es kommt nur darauf an, daß die Kühlung so geführt wird, daß die Temperatur des ausfließenden, mit Staub beladenen Wassers noch 75' C überschreitet; bei einem Raschigturm beispielsweise werden die Höhe der Raschigringe und der Querschnitt des Kühlers entsprechend zu wählen sein, bei Oberflächenkühlern die Größe der Kühlfläche und die Temperatur des Kühlwassers.Any cooler can be used to carry out the process, for example a sprinkler cooler or a surface cooler i. Leave it No rules are given for this in detail, it just depends on the Cooling is carried out so that the temperature of the outflowing, laden with dust Water still exceeds 75 ° C; in a Raschig tower, for example, the The height of the Raschig rings and the cross-section of the cooler must be selected accordingly, in the case of surface coolers, the size of the cooling surface and the temperature of the cooling water.
