Description

Verfahren zur Herstellung von Briketten. Die Herstellung von Briketten aus Koksgrieß oder Koksstaub und Pech ist bekannt. Ferner kennt man auch schon Verfahren, um Brikettspeise aus Kohlenklein und Pech unter Dampfeinführung in einem offenen Zylinder zu mischen. Hierbei hat es sich gezeigt, daß der Dampf (auch Frischdampf), weil wasserhaltig, die klebende Fähigkeit des Peches nachteilig beein$ußt. Dieser Mißstand kann auch dann nicht beseitigt werden, wenn man die Bearbeitung der Brikettspeise aus Kohlenstücken und Pech o. dgl. mit Dampf, wie es gleichfalls bekannt ist, in einem geschlossenen Behälter unter Druck vornahm. Man mußte infolgedessen in einem zweiten Arbeitsvorgang die Brikettmasse in einem geschlossenen Zylinder unter der Einwirkung indirekter Wärme einem weiteren Mischvorgang unterwerfen, um auf diese Weise ein Überziehen der einzelnen Kohlestückchen mit dem Bindemittel zu bewirken und die Kohäsion zu vergrößern. Es hat sich nun überraschenderweise gezeigt, daß es dieses zweiten Arbeitsvorganges nicht bedarf, wenn man an Stelle von Kohlestückchen oder Kohlenklein und Pechstaub o. dgl. Koksgrieß oder -staub mit Pech durch unmittelbares Einleiten von möglichst wasserfreiem Dampf (Frischdampf) in einem möglichst dampfdicht geschlossenen Behälter unter Druck mischt. In diesem Falle kann man unmittelbar hierauf das Mischgut brikettieren.Process for the production of briquettes. The production of briquettes from coke grits or coke dust and pitch is known. Furthermore, one already knows procedures for briquette food made from coal and pitch with the introduction of steam in an open Mix cylinder. It has been shown that the steam (also live steam), because it contains water, it has a detrimental effect on the adhesive properties of the pitch. This Even if you start processing the briquette dish, grievance cannot be remedied from pieces of coal and pitch or the like with steam, as it is also known, in performed in a closed container under pressure. As a result, one had to be in one second operation the briquette mass in a closed cylinder under the Submit exposure to indirect heat to another mixing process in order to act on this Way to cause a coating of the individual pieces of coal with the binder and increase cohesion. It has now been shown, surprisingly, that there is no need for this second operation if one takes the place of bits of coal or coal grit and pitch dust or the like. Coke grits or dust with pitch through immediate Introduce steam that is as water-free as possible (live steam) in a room that is as vapor-tight as possible closed container mixes under pressure. In this case one can immediately then briquette the mix.

In Ausübung des Verfahrens wird der Koksgrieß (Koksabfall) zunächst mit etwa 7 Prozent ungefähr zu Mehlfeinheit vermahlenem Pech (Steinkohlenteerpech) innig trocken gemischt und dann in der oben beschriebenen Weise in möglichst dampfdicht geschlossenen Mischtrommeln mit wasserfreiem Dampf (Frischdampf) behandelt. Diese Behandlung wird zweckmäßig unter Dampfdruck bis zu i Atm. etwa 1!. Stunde fortgesetzt. Die erhaltene Masse wird sodann zweckmäßig in Kalksandsteinpressen zu Briketten verpreßt. Die letzteren erhärten an der Luft rasch und sind in wenigen Stunden gebrauchsfertig.In exercising the process, the coke grit (coke waste) is initially with about 7 percent pitch ground to a flour fineness (coal tar pitch) intimately dry mixed and then in the manner described above in as vapor-tight as possible closed mixing drums treated with anhydrous steam (live steam). These Treatment is expedient under vapor pressure up to 1 atm. about 1 !. Hour continued. The mass obtained is then expediently made into briquettes in sand-lime brick presses pressed. The latter harden quickly in air and are ready for use in a few hours.
