Description

Durchführung exothermischer Umsetzungen lös hat sich bei Durchsetzung von e%other-Alischen Prozessen in beheizten Drehöfen oller Drehtrommehi. beispielsweise bei der Behandlung von Metallverbindungen, wie Stiltiden t1. dgl., gezeigt. daß dadurch, daß die hei deni Umsetzungsprozeß frei werdende @.t:@rme nicht schnell genug abgeführt werden .ante, Erweichungen und Schmelzungen des #.t1 behandelnden Gutes eintraten, die zu Betriebsstörungen führten durch Ansat7bilclunren oder Klumpenbildungen des Brenngutes. Bei Ansatzbildungen mußte der Drehofen sehr bald stillgesetzt werden. weil der Ofen langsani zuwuchs und die Leistung dadurch rapid abnahm. Die Klumpenbildung aber hatte zur Folge, claß der Kern der Klumpen trotz größter "Temperatursteigerung nicht mehr gargebrannt werden konnte, teils weil die äußere Schicht der Klumpen isolierte, teils weil z. T. k(-in Sauerstoff mehr zum Kern der Klumpen drin-en konnte.Carrying out exothermic reactions has proven itself in enforcement of e% other-alic processes in heated rotary ovens or rotary drums. for example in the treatment of metal compounds, such as Stiltiden t1. Like. Shown. that by the fact that the hot deni implementation process becomes free @ .t: @rme not fast enough to be discharged .ante, softening and melting of the # .t1 treating Good things occurred which led to operational disruptions due to accumulation or lump formation of the material to be fired. The rotary kiln had to be shut down very soon when deposits formed. because the furnace grew slowly and the output decreased rapidly. The clumping but the result was that the core of the lump was in spite of the greatest increase in temperature could no longer be cooked, partly because the outer layer of the lump isolated, partly because z. T. k (-in oxygen more to the core of the lump inside.

Dieser Mangel wird behoben dadurch, daß inall in dem Ofen die Zone, in welcher die 1-Iauptvorgänge verlaufen, mit Metall- oder sonstigen Körpern in der Menge fiillt. daß die überschüssige Wärme von diesen Körpern aufgenommen und an die Wandung der Tronlniel bzw. an die durchstreichenden Gase abgegeben wird, so daß das -Material nicht bis ztt seinem Erweichungs- oder Schmelzpunkt erhitzt werden kann.This deficiency is remedied by the fact that in all of the furnace the zone in which the main processes take place, with metal or other bodies in the crowd fills. that the excess heat is absorbed by these bodies and is released to the wall of the barrel or to the gas being passed through, so that the material is not heated to its softening or melting point can be.

Die Menge der zugeführten -Metall- oder sonstigen Körper muß dabei zu der Materialmenge mindestens im Verhältnis von i : i stehen, damit diese Körper sich mit dem Material vollständig durchmischen und an jeder Stelle des Materials die aus ihm entstehende Wärme aufnehmen.The amount of -metal- or other body supplied must be to the amount of material are at least in the ratio of i: i so that these bodies mix completely with the material and at every point on the material absorb the heat that arises from it.

In Trockentrommeln und Brenntrommeln hat man schon Metallkörper in Gestalt von beweglichen Rohren, Ketten, an Ketten aufgehängten Stücken, Wahlkörpern usw. verwendet, die aber in erster Linie dazu benutzt werden. um größere Klumpen zu zerstören und das Festsetzen des Brenngutes an den Wandungen zu verhindern. Dabei kann teilweise auch eine Übertragung von Wärme stattfinden, aber nur in verhältnismäßig geringem Maße, da die betreffenden Körper, wie Ketten usw., nur mit ihrem kleinsten Teil mit dein Gut selbst in Berührung kommen.In drying drums and firing drums you already have metal bodies in Shape of moving pipes, chains, pieces suspended from chains, electoral bodies etc., which are primarily used for this. around larger lumps to destroy and to prevent the material to be fired from sticking to the walls. Included a transfer of heat can also take place in some cases, but only in proportion to a small extent, since the bodies in question, such as chains, etc., only with their smallest Part of getting in touch with your own property.

Gemäß der vorliegenden Erfindung findet eine vollständige -Mischung der -Metallkörper finit dein -Material und eine gegenseitige Ein-Z, statt, die die bei der etotherinischen t'insetzung entstehende Wärine sofort auf-Z' tuld abführt.According to the present invention is a complete mixture of -Metallkörper finit your material and a mutual input Z, instead of the up Z 'dissipates the heat produced in the etotherinischen t'insetzung Wärine immediately tuld.
