Die Gase von den Röstöfen kommen durch Kanal a, umspülen das eiserne, verbleite Luftreservoir A und die geschlossenen Bleipfannen B auf dem mit b bezeichneten Wege und werden durch den eisernen Kreuzkopf D in den runden Bleithurm E, welcher hoch auf einem gemauerten': Sockel steht, gesaugt. Ein Ventilator oder eine Esse wirken saugend oben auf den Thurm E vermittelst des Abzugsrohres F ein. Das Reservoir G enthält Wasser, welches durch den bleiernen Vertheilungsapparat H in den Thurm E fliefst. Der Thurm E ist mit Koks, Quarz oder anderem säurebeständigen Material, welches eine gute Zertheilung des Wassers ermöglicht, ausgesetzt. Das Wasser absorbirt beim Herabfliefsen im Thurm die in den Röstgasen enthaltene schweflige Säure, Schwefelsäure und Vitriole. Die Lösung fliefst durch Bleirohr c in die Bleipfannen B und wird hier durch die Wärme der Röstgase erhitzt. Die Verbindungsröhren d der Bleipfannen B befinden sich immer in den diagonal gegenüberstehenden Ecken und führen die Lösung- aus der oberen Bleipfanne oben ab und in die darunter befindliche Pfanne .bunten ein. Aus der letzten Pfanne fliefst das saure Wasser durch natürlichen Druck vermittelst des Rohres e in den Thurm M oben ein. Der Thurm M ist ebenfalls von Blei, durch denselben geht die verticale eiserne, verbleite Welle JV, an der die Scheiben O befestigt •sind.-··-"'The gases from the roasters come through channel A, the iron, leaded air reservoir A, and the sealed lead pans B umspülen on the b designated paths and through the iron crosshead D in the lead circular tower E, which high on a brick ': represents base , sucked. A fan or a chimney has a suction effect on top of the tower E by means of the flue pipe F. The reservoir G contains water which flows through the leaden distribution apparatus H into the tower E. The tower E is exposed to coke, quartz or other acid-resistant material that enables the water to be well dispersed. As it flows down in the tower, the water absorbs the sulphurous acid, sulfuric acid and vitriols contained in the roasting gases. The solution flows through lead pipe c into lead pans B and is heated here by the heat of the roasting gases. The connecting tubes d of the lead pans B are always in the diagonally opposite corners and lead the solution from the top lead pan at the top and into the pan below. The acidic water flows from the last pan through natural pressure through the pipe e into the tower M above . The tower M is also made of lead, through it goes the vertical iron, leaded shaft JV, to which the discs O are attached.

Die Welle wird durch Maschinenkraft in Rotation versetzt. An der Wand des Thurmes , rings herum befinden sich die Bleiteller P. Das durch e einfliefsende erwärmte saure Wasser wird--* ,durch diese Vorrichtung während des Herabfliefsens herumgeschleudert und dadurch 'fe^n zertheilt und zerstäubt. In den Thurm M strömt unten atmosphärische Luft ein, welche durch"*Rghr / dem Apparat R zugeführt wird, aus R durch g in das Lu.ftreservoir A tritt und durch Rohr h'. in den Thurm M hineingeht. Der Apparat R besteht aus den cylindrischen Bleigefäfseny und J₁, die durch die Bleirohre q mit einander verbunden sind. Die Bleirohre q werden vermittelst der eisernen, verbleiten Scheiben .S in ihrer Lage erhalten. Das Ganze liegt in einem vollständig geschlossenen Bleireservoir. Das aus M durch i abfliefsende heifse Wasser umspült den Apparat R, fliefst durch k in das Reservoir U und wird durch eine Pumpe H wieder in das Reservoir G auf Thurm E gehoben und von neuem zur Absorption der schwefligen Säure in E gebraucht. Im Apparat R giebt das Wasser seine Wärme an die Luft ab und kommt wieder kalt in das Reservoir G. The shaft is set in rotation by machine power. Are located on the wall of the tower, all around the lead plate P. The einfliefsende by e heated acidic water is - *, thrown around by this apparatus during the Herabfliefsens and thereby 'fe ^ n zertheilt and atomized. Atmospheric air flows into the tower M at the bottom, which is fed through "* Rghr / to the apparatus R, exits from R through g into the air reservoir A and enters the tower M through tube h ' . The apparatus R consists of the cylindrical Bleigefäfseny and J _1, the q by the lead pipes, the lead pipes are connected with each other. q by means of the iron, leaded discs .S in position obtained. the whole is in a completely closed lead reservoir. the from M torrid by i abfliefsende Water washes around the apparatus R, flows through k into the reservoir U and is lifted again into the reservoir G on tower E by a pump H and is used again for the absorption of the sulphurous acid in E. In the apparatus R the water gives off its heat Air and comes back cold into the reservoir G.

Der Apparat R wird so lang genommen, dafs die Wärme des aus dem Thurm M kommenden Wassers vollständig ausgenutzt wird. Die Luft kommt warm in das Reservoir A und wird hier durch die Ofengase noch mehr er-The apparatus R is taken so long that the heat of the water coming from the tower M is fully utilized. The air comes warm into the reservoir A and is here even more

warms, so that it enters the tower M through the openings m completely hot. The atomized water flowing down in the tower M gives off its sulphurous acid completely. This is carried away with the air through lead pipe W to the point where the sulphurous acid is to be processed further. The water will gradually become enriched with sulfuric acid, iron and zinc vitriol, as it is continually being used again. If it is so rich in these substances that it is worthwhile to obtain them by evaporation, a portion is drained through the pipe η into the lead pans D and replaced by fresh water. The hot gases coming from the roasting ovens appear under D , if one wishes to concentrate in D , in the other case they enter directly at Z. The sulphurous acid which develops in the lead pans B is fed to the tower M through the lead pipe O. .

Pate nt claims:

i. For the purpose of transferring the heat of the hot, deacidified water to the air blown into the tower, the use of the apparatus Ji, which consists of a large number of thin-walled lead pipes, which connect two cylindrical lead vessels with one another and are held in place by iron, leaded discs , and through which the hot water from M flows in such a way that it enters at the bottom end where the air flows out to boiler A and at the other end exits to the reservoir U. For the purpose of utilizing the heat of the roasting gases, the application :

a) the closed lead pans B, in which the flowing down, from ThurmZ? Incoming acidic water is preheated by the hot roasting gases flowing in the opposite direction, which wash around the lead pans;

b) the leaded iron air reservoir A, which is surrounded by the hot roasting gases from the inside and outside, and

c) Concentration pans D for obtaining sulfuric acid, iron and zinc vitriol from the absorption water by means of evaporation through the hot roasting gases.

For this purpose 2 sheets of drawings.
