Description

Verfahren der Herstellung von Brennstoffbriketten aus Klärschlamm und Brennstoffabfällen unter Zusatz Von gebranntem Kalk. Es ist bekannt, den Schlamm von Kläranlagen durch Zusatz ungelöschten Kalks zu trocknen, mit Brennstoffabfällen zu vermischen und aus dem Gemisch unter Zusatz eines Bindemittels, wie Teer, Öl o. dgl., Brikette herzustellen. Andererseits isst es bekannt, feuchtem Brennstoff zum schnellen Binden bvw. Trocknen des geformten Materials kurz vor der Verpressung Ätzkalk zuzusetzen.Process for the production of fuel briquettes from sewage sludge and fuel waste with the addition of quick lime. It is known the mud of sewage treatment plants by adding unslaked lime to dry with fuel waste to mix and from the mixture with the addition of a binder such as tar, oil o. The like. To make briquette. On the other hand, it is known to eat moist fuel for quick binding bvw. Drying the shaped material shortly before pressing Add quick lime.

Die Erfindung bezweckt die Herstellung von Brennstoffbriketten aus Klärschlamm, welcher der Trocknung und Brikettierung die größten Schwierigkeiten bereitet, unter Benutzung des für das Brikettieren feuchter Brennstoffe, insbesondere Braunkohlen, bekannten Kalkzusatzes.The invention aims at the production of fuel briquettes Sewage sludge, which of the drying and briquetting the greatest difficulties prepares using the for the briquetting of moist fuels, in particular Lignite, known additive of lime.

Das Verfahren wird in der Weise ausgeführt, daß zunächst der feuchte Klärschlamm mit wertlosen Brennstoffabfällen, wie Koks-und Kohlengrus, Sägemehl usw., vermischt und dem Gemisch erst unmittelbar vor dem Eintritt in die .Presse ungelöschter Kalk in gemahlenem Zustand und in solcher Menge zugesetzt wird, daß die Bildfähigkeit der Masse zunächst, d. h. während des Durchgangs durch die Presse, nicht leidet und die Löschung des Kalkes erst in dem fertigen Brikett zu Ende geht.The method is carried out in such a way that first the moist Sewage sludge with worthless fuel waste, such as coke and coal grit, sawdust etc., mixed and the mixture just before entering the .Press unslaked lime is added in the ground state and in such an amount that the image ability of the mass first, d. H. during the passage through the press, does not suffer and the extinction of the lime only comes to an end in the finished briquette.

Die Vorzüge des Verfahrens bestehen darin, däß die getrocknete Mischung nicht erst wieder in einen, formbaren Zustand zurückgebracht werden muß: Ferner entweichen bei dem Trocknen und Mischen der Masse viele für die Verbrennung wertvolle Gase, während bei dem neuen Verfahren, bei dem die Feuchtigkeitsentziehung in der Hauptsache während des Pressens und nachher vor sich geht, in dem Brikett Hohlräume in großer Zahl entstehen, in welchen die Gase eingeschlossen sind, so daß sie erst bei der Verbrennung frei werden. Die nach diesem Verfahren hergestellten Brikette haben also eine größere Heizkraft und bedürfen auch nicht eines besonderen Bindemittels.The advantages of the process are that the dried mixture does not have to be brought back into a malleable state: further During the drying and mixing of the mass, many valuable for incineration escape Gases, while in the new process, in which the dehumidification in the The main thing is during pressing and afterwards, in the briquette cavities arise in large numbers, in which the gases are enclosed, so that they only are released during combustion. The briquette produced by this process therefore have a greater heating power and do not require a special binder.

Das Verfahren wird z. B. in folgender Weise- ausgeführt: In einem Vormischer wird Klärschlamm mit beliebigen Brennstoffabfällen, wie Kohlen und Kohlengrus, Sägemehl u. dgl., gemischt und die Mischung durch eine Förderschnecke zu einer Presse beliebiger Bauart gefördert. In der Förderschnecke wird dem Gemisch ungelöschter Kalk -in gemahlenem Zustande zugesetzt.The method is e.g. B. executed in the following way: In one Premixer is sewage sludge with any fuel waste, such as coal and coal grit, Sawdust and the like, mixed and the mixture through a screw conveyor to a press of any type promoted. The mixture becomes less extinguished in the screw conveyor Lime-added in a ground state.

Der. Kalk erhöht die Bindekraft des Gemenges, ohne aber, da die Löschung eine gewisse Zeit in Anspruch nimmt, die Masse bereits in- der Presse völlig auszutrocknen. Durch die Pressung werden die im Schlamm vorhandenen Gase am Entweichen verhindert und in den zahlreichen Hohlräumen des porösen Gemenges eingeschlossen.Of the. Lime increases the binding force of the mixture, but without, as the extinguishing takes a certain amount of time to completely dry out the mass in the press. The pressure prevents the gases present in the sludge from escaping and enclosed in the numerous cavities of the porous mixture.
