Description
Verfahren zur Trocknung riaß granulierter Schlacke mittels feuerflüssiger Hochofenschlacke. Bei dem Patent 249129 erfolgt die Zerstäubung flüssiger Schlacke in einem geneigten und gekühlten Rohr, das sich zweckmäßig in Umdrehung befindet, und in dein die flüssige Schlacke auf ihrem Durchgang der Einwirkung eines Luft- oder Dampfstromes ausgesetzt wird. Hierbei werden große Wärmemengen frei.Process for drying granulated slag by means of hot liquid Blast furnace slag. In patent 249129, liquid slag is atomized in an inclined and cooled tube, which is expediently in rotation, and in your the liquid slag on its passage under the action of an air or is exposed to a stream of steam. This releases large amounts of heat.
Das vorliegende Verfahren bezweckt nun, diese sonst verlorengehende Wärme nutzbringend zur Trocknung nassen wassergranulierten' Schlackensandes zu verwenden. Hierzu wird der nasse Schlackensand durch die Zerstäubungstroriimel hindurchgeschickt und so mit der heißen luftgranulierten Schlacke gemischt, daß dieser die enthaltene Wärme entzogen wird.The purpose of the present proceedings is now to remedy this, which would otherwise be lost Use heat beneficially to dry wet water-granulated slag sand. For this purpose, the wet slag sand is sent through the atomizing channel and mixed with the hot, air-granulated slag so that it contains the Heat is withdrawn.
Nun wird aber noch bei der Luftgranulierung von Schlacke zur weiteren Abkühlung Wasser in die Luftgranuliertrommel eingeführt- Diese Wasserzufuhr kann jetzt ganz oder teilweise entfallen, j e nach der zugeführten Schlackenmenge, denn die Feuchtigkeit der zugeführten naß granulierten Schlacke kann die sonst zugeführte Wassermenge ersetzen.But now, with air granulation, slag becomes another Cooling water introduced into the air granulating drum- This water supply can now completely or partially omitted, depending on the amount of slag supplied, because the moisture of the supplied wet granulated slag can reduce the otherwise supplied Replace the amount of water.
Die Hütten-werke, die heutzutage noch überwiegend die namentlich aus dem Hochofen abgehende Schlacke auf nassem Wege granulieren, erhalten auf diese Weise eine einfache äußerst billige Möglichkeit zur Trocknung ihrer Schlacke.The ironworks, which nowadays still predominantly consist of names Granulate slag leaving the blast furnace in a wet way, get on this Way an easy extremely cheap way to dry your slag.
