Description

Verfahren zur Herstellung von Torfbriketten durch Formen von vorgetrocknetem und mit eingedickter Sulfitzellstoffablauge gemischtem Rohtorf auf kaltem Wege ohne Anwendung von hohem Druck. Die Herstellung von Torfbriketten durch Formen von vorgetrocknetem und mit eingedickter Sulfitzellstoffablauge gemischtem Rohtorf auf kaltem Wege ist bekannt. Bei all diesen Verfahren aber wird die Sulfitzellstoffablauge, gleichgültig, ob unter Druck oder ohne wesentlichen Druck gearbeitet wird, als Bindemittel benutzt. In der Tat wirkt sie dabei aber kaum als solches. Denn bei Anwendung von Druck wird die Sulfitzellstoffablauge aus dem Formling abgepreßt. Wird aber ohne Anwendung von erheblichem Druck geformt, so fließt der größte Teil der Sulfitzellstoffablauge anschließend an den Formvorgang nach unten ab und verdichtet sich zum Teil auf der Unterfläche des Formlings zu einer Kruste.Process for the production of peat briquettes by molding pre-dried and raw peat mixed with concentrated sulphite pulp waste liquor on a cold route without Application of high pressure. The manufacture of peat briquettes by molding pre-dried and raw peat mixed with concentrated sulphite pulp liquor is cold known. In all these processes, however, the sulphite pulp waste liquor is indifferently whether it is working under pressure or without substantial pressure, is used as a binder. In fact, it hardly acts as such. Because when pressure is applied the sulphite pulp liquor is pressed out of the molding. But without application Formed by considerable pressure, most of the sulphite pulp waste liquor flows then to the molding process downwards and partially condenses on the Undersurface of the molding to form a crust.

Nach der Erfindung wird die Sulfitzellstoffablauge dazu benutzt, eine Kruste zu bilden, welche die getrockneten Formlinge auf ihrer ganzen Oberfläche möglichst gleichmäßig überzieht, sie auf diese Weise zusammenhält und luftdicht nach außen abschließt. Dies wird dadurch erreicht, daß die zum Trocknen aufgestellten Formlinge nach kurzer Zeit, unter Umständen öfter, derart umgewendet werden, daß die angegebene Wirkung erzielt wird.According to the invention, the sulfite pulp waste liquor is used to a To form crust, which the dried briquettes on their entire surface as evenly as possible, thus holding them together and making them airtight closes to the outside. This is achieved in that the set up to dry Moldings are turned over after a short time, possibly more often, in such a way that the specified effect is achieved.

Um nun hierbei der Sulfitzellstoffablauge ihre hygroskopische Eigenschaft zu nehmen, wird die Torf-Sulfitzellstoffablauge-Mischung mit einem Zusatz von Talkum, Kieselgur, Alaun, Asbest oder von alkalischen Lösungen von Harzen, Hornabfällen u. dgl. versehen.In order to ensure that the sulphite pulp waste liquor has its hygroscopic property to take, the peat-sulphite pulp liquor mixture with an addition of talc, Diatomite, alum, asbestos or alkaline solutions of resins, horn waste and the like.

Wohl ist es bei warmen Verfahren zur Herstellung von Torfbriketten bekannt, der Sulfitzellstoffablauge Zusätze zu geben, welche sie urhygroskopisch machen. Diese Zusätze bestehen aus Teerprodukten, wie Asphalt, Wachs, Harz sowie Leim u. dgl. Diese Zusätze sind bei sogenannten Kaltverfahren jedoch wirkungslos, im Gegensatz zu den genannten Stoffen wie Talkum, Kieselgur, Alaun, Asbest, alkalische Lösungen von Harz, Hornabfälle u. dgl. .It is probably the case with warm processes for the production of peat briquettes known to give additives to the sulphite pulp waste liquor, which make them urhygroscopic do. These additives consist of tar products such as asphalt, wax, resin as well Glue and the like. These additives are ineffective in so-called cold processes, in contrast to the substances mentioned such as talc, diatomite, alum, asbestos, alkaline Solutions of resin, horn waste and the like.

Eine Ausführungsform des eben gekennzeichneten Verfahrens ist folgende Man trocknet den Rohtorf in bekannter Weise vor, indem man ihn auf große Haufen legt und einige Wochen der Luft aussetzt, wodurch etwa 50 Prozent der ihm innewohnen. den Feuchtigkeit verdunsten. Diesem vorgetrockneten Rohtorf werden etwa 1o bis 2o Prozent von auf ungefähr 35 bis 50° B6 eingedickter Sulfitzellstoffablauge und etwa 15 bis 2o. Prozent gepulvertes Talkum zugesetzt; das Ganze wird innig vermischt und die so gewonnene Mischung alsdann in beliebige Form gebracht. Die Formlinge werden zum Trocknen zweckmäßig an der Luft aufgestellt und dabei von Zeit zu Zeit umgewendet. Die Folge davon ist, daß die eingedickte Sulfitzellstoffablauge mit ihrem Zusatz nach außen tritt und sich insbesondere seitlich- und unten an der Oberfläche der Formlinge sammelt. Um die Sulfitzellstoffablauge dabei auf der Oberfläche möglichst gleichmäßig zu verteilen, müssen die Formlinge nach kurzer Zeit, -und zwar unter Umständen auch öfter, umgewendet werden. Der so gebildete Überzug der Formlinge erhärtet bei trockenem Wetter verhältnismäßig rasch und schließt die letzteren in Form einer pechartigen Kruste nach außen luftdicht ab.One embodiment of the method just identified is as follows: The raw peat is pre-dried in a known manner by laying it in large piles and exposing it to the air for a few weeks, as a result of which about 50 percent of it is inherent. the moisture evaporate. About 1o to 2o percent of sulphite pulp waste liquor thickened to about 35 to 50 ° B6 and about 15 to 2o percent are added to this predried raw peat. Percent powdered talc added; the whole is intimately mixed and the mixture obtained in this way is then brought into any shape. The moldings are expediently placed in the air to dry and turned over from time to time. The consequence of this is that the thickened sulphite pulp waste liquor with its additive escapes to the outside and collects in particular on the side and bottom of the surface of the briquettes. In order to distribute the sulphite pulp waste liquor as evenly as possible on the surface, the briquettes have to be turned over after a short time, and in some cases more often. The coating of the briquettes formed in this way hardens relatively quickly in dry weather and closes the latter airtight from the outside in the form of a pitch-like crust.
