Die vorliegende Erfindung betrifft ein Verfahren/, nach welchem solche Stoffe, die sich wegen ihres großen Feuchtigkeitsgehaltes bisher in Meilern nicht gut verkohlen ließen, für die Meilerverkohlung geeignet gemacht werden sollen, indem ihnen durch eine Vorbehandlung auf kaltem Wege neben dem mechanisch anhaftenden auch das gebundene Wasser möglichst entzogen wird. Zu diesenThe present invention relates to a method / according to which such substances that due to their high moisture content have so far not charred well in piles, should be made suitable for the coaling of piles by giving them a pretreatment In addition to the mechanically adhering water, the bound water is also removed as far as possible by cold means. To this
ίο Stoffen gehören insbesondere Torf, Lignit und lignitähnliche Braunkohle usw. Diese Stoffe zerfallen im Meiler deshalb in kleinere Stücke, weil die sich aus der gebundenen Feuchtigkeit entwickelnden Wasserdämpfe das Material sprengen und zerkleinern. Um nun die Struktur des Stoffes im Meiler unverändert zu behalten, ist es notwendig, ihm vor dem Vermeilern die Feuchtigkeit zu entziehen, jedoch nicht durch Erhitzung, da sonst die Struktur schon vor der Vermeilerung teilweise zerstört würde, sondern die Entziehung der Feuchtigkeit muß ohne Wärmeerhöhung erfolgen.ίο Substances include in particular peat, lignite and lignite-like lignite, etc. These substances therefore break down into smaller ones in the kiln Pieces, because the water vapors developing from the bound moisture blast and crush the material. To now the structure of the substance in the kiln unchanged it is necessary to remove the moisture from it before sowing, but not by heating, as otherwise the structure would be partially destroyed before the propagation, but the Withdrawal of moisture must take place without increasing heat.
Hierzu wird nun Sulfitzelluloselauge verwendet. Sulfitzelluloselauge, die bis zu einem gewissen Grade eingedickt ist, hat die Eigenschaft, nicht hygroskopisch zu sein, d. h. sie entzieht an der Luft stehend letzterer die Feuchtigkeit nicht nur nicht, sondern wird noch konsistenter. Bestreicht man aber Stoffe, welche Feuchtigkeit in sich gebunden enthalten, mit Sulfitzelluloselauge, so entzieht dieselbe den Stoffen ihre Feuchtigkeit begierig und wird dünnflüssig. Diese verwässerte Lauge wird dann durch Verdunstung oder auf andere Weise wieder verdickt und kann neuerlich verwendet werden usf.Sulphite cellulose lye is now used for this purpose. Sulphite cellulose eye, which is up to one is thickened to a certain extent, has the property of not being hygroscopic, i. H. she Standing in the air, the latter not only does not remove the moisture, but becomes even more consistent. However, if you coat fabrics that bind moisture contained, with sulphite cellulose lye, it avidly withdraws its moisture from the substances and becomes thin. This diluted liquor is then re-thickened and re-thickened by evaporation or other means can be used again etc.
Um nun die nicht meilerbaren Stoffe zum Meilern geeignet zu machen, begießt oder bestreicht man sie mit eingedickter Sulfitzelluloselauge oder man legt diese Stoffe in die Lauge hinein. Nach kurzer Zeit entzieht letztere den Stoffen die gebundene Feuchtigkeit, worauf sie zur Behandlung im Meiler geeignet sind.In order to make the substances that cannot be kilned suitable for kilning, water or you coat them with thickened sulphite cellulose lye or you put these substances in the lye in. After a short time, the latter removes the bound moisture from the fabrics, whereupon they are suitable for treatment in the kiln.
Versuche haben ergeben, daß der Feuchtigkeitsgehalt z. B. von Schlammtorf mit 80,34 Prozent auf 7,62 Prozent, von märkischer Braunkohle mit 56,43 Prozent auf 6,01 Prozent, von böhmischer Braunkohle mit 36,72 Prozent auf 8,12 Prozent erniedrigt wird, wenn diese Stoffe in der angegebenen Weise mit Sulfitzelluloselauge behandelt werden. Tests have shown that the moisture content z. B. of mud peat with 80.34 percent to 7.62 percent, from Brandenburg lignite with 56.43 percent to 6.01 percent, from Bohemian lignite with 36.72 percent to 8.12 percent is reduced if these substances in the specified Way to be treated with sulphite cellulose solution.
