Description

Verfahren zum Ent- und (oder) Vergasen von Waschbergen In neuerer "Zeit sind mehrfach Verfahren entwickelt worden, die bei der Aufbereitung der Steinkohlen anfallenden Gemische von brennbaren und unbrennbaren Bestandteilen durch Entgasen oder Vergasen, gegebenenfalls durch aufeinanderfolgen.-des Entgasen und Vergasen nutzbar zu machen.Process for degassing and (or) gasifying wash mountains In more recent "During the time, several processes have been developed that are used in the preparation of hard coal accruing mixtures of flammable and non-flammable components through degassing or gasification, if necessary by successive degassing and gasification to make usable.

. Da eine trockene Destillation mit mittelbarer Beheizung insbesondere deswegen nicht in Frage kommt, weil infolge des geringen Anteiles der Waschberge an brennbaren Bestandteilen mit einer Koksgewinnung nicht zu rechnen ist, erweist sich auch beim Entgasen die unmittelbare Beheizung als die vorteilhaftere.. As a dry distillation with indirect heating in particular therefore out of the question, because as a result of the low proportion of wash mountains coke production is not to be expected on combustible components, proves Direct heating is also more advantageous when degassing.

Sowohl für eine unmittelbare Erwärmung beim Entgasen als auch für ein Vergasen ist die Gasdurchlässigkeit von entscheidender Bedeutung. Diese ist bei den Waschbergen mit ihrem hohen Anteil an Feinkorn ziemlich gering. Es wurde nun gefunden, daß eine Verarbeitung von Waschbergen sowohl beim Entgasen als auch beim Vergasen dann möglich ist, wenn das Feinkorn bis zu einer Korngröße von vorzugsweise io mm von dem gröberen Korn getrennt und brikettiert wird. Die Brikettierung läßt sich in den meisten Fällen durchführen, ohne daß ein Bindemittel Verwendung findet, weil die Gangart der Kohle in den meisten Fällen tonige Bestandteile enthält, welche ein genügendes Zusammenbacken bewirken. Die gewonnenen Preßlinge werden vorzugsweise gesondert von dem grobkörnigen Bestandteil der Berge dem Entgasungs- und (oder) Vergasungsverfahren unterworfen.Both for immediate heating during degassing and for Gas permeability is of crucial importance for gasification. This is in the wash mountains with their high proportion of fine grain it is quite low. It was now found that a processing of wash mountains both during degassing as well when gasifying is possible if the fine grain up to a grain size of preferably 10 mm is separated from the coarser grain and briquetted. The briquetting leaves can be carried out in most cases without the use of a binding agent, because the gangue of coal in most cases contains clayey components, which cause sufficient caking. The obtained compacts are preferred separately from the coarse-grained part of the mountains the degassing and (or) Subjected to gasification processes.

Ausführungsbeispiele i. Das bei der Aufbereitung in den Bergen enthaltene Unterkorn unter io mm, das je nach Art der Kohlenaufbereitungsanlage noch etwa 2o bis 25% Brennbares enthält, aber nicht für die unmittelbare Vergasung geeignet ist, wurde in feuchtem Zustande mit einem Wassergehalt von etwa 5 bis 7% auf einer Ringwalzenpresse zu etwa 13 bis Sog schweren Eierbriketts verpreßt. Die Preßlinge sind unmittelbar für die Vergasung im Generator oder zur Verbrennung auf dem Wanderrost geeignet. Versuche ergaben, daß die Preßlinge auch im Dauerbrenner bis auf Spuren von Verbrennlichem ausbrannten.Embodiments i. That contained in the processing in the mountains Undersize less than 10 mm, depending on the species the coal processing plant still contains about 20 to 25% combustibles, but not for immediate gasification is suitable, was in a moist state with a water content of about 5 to 7% pressed on a ring roller press into about 13 up to suction heavy egg briquettes. the Pressings are immediately ready for gasification in the generator or for combustion suitable for the traveling grate. Tests have shown that the pellets are also popular burned out except for traces of combustibles.

z. Ein aus einer Köhlenflotationsanlage staminender Wäscheschlamm, der etwa 3o bis 40% Verbrennliches enthielt, wurde in feuchtem Zustande mit einem Wassergehalt bis zu 40% auf einer Ringwalzenpresse verpreßt. Dabei trat ein Teil des Wassers aus, so daß die Formlinge etwas mehr als 20% Wasser enthielten. Die Formlinge waren für die Vergasung hinreichend fest und brannten hei der Vergasung oder Verbrennung bis auf Spuren von Verbrennlichem aus.z. A laundry sludge stemming from a coal flotation plant, which contained about 30 to 40% combustibles, was wet with a Water content up to 40% pressed on a ring roller press. A part of it stepped of the water, so that the briquettes contained a little more than 20% water. the Briquettes were strong enough for gassing and burned during gassing or incineration except for traces of combustibles.
