Description
Verfahren zum Entwässern von Rohtorf Bei der Entwässerung von Rohtorf in Hochdruckpressen mit mechanischem oder hydraulischem Antrieb konnte bisher auch bei Benutzung von koaguliertem Rohtorf nicht über zo Atm. Enddruck angewandt werden, ohne daß ein beachtlicher Teil des feinkolloiden Torfstoffes verlorengegangen wäre.Process for dewatering raw peat When dewatering raw peat in high pressure presses with mechanical or hydraulic drive could also when using coagulated raw peat not above zo atm. Final pressure are applied, without a considerable part of the fine colloid peat material having been lost.
Durch das Patent 643 498 ist ein Verfahren unter Schutz gestellt worden, nach welchem koagulierter Rohtorf in übereinanderliegenden Filterkästen, in die dünne Schichten koagulierten Rohtorfes eingebracht sind, bei langsam ansteigendem Preßdruck, der durch das Eigengewicht der Filterkästen entsteht, entwässert wird. Bei einem Enddruck von nicht über 6 Atm. wird hierbei eine von Torfstoffverlusten ganz frei bleibende Rohtorfentwässerung erzielt, wobei das gewonnene Preßgut je nach dein Zersetzungsgrad des Rohtorfes einen Wassergehalt von 75 bis 70 °/o hat.A process has been protected by patent 643 498, after which coagulated raw peat in stacked filter boxes, into the thin layers of coagulated raw peat are introduced, with slowly increasing Pressing pressure, which is created by the weight of the filter boxes, is drained. At a final pressure of not more than 6 atm. becomes one of peat losses Achieved completely free raw peat drainage, the pressed material obtained depending according to the degree of decomposition of the raw peat has a water content of 75 to 70%.
Es hat sich nun gezeigt, daß der auf diese Weise vorentwässerte Torf in einer Hochdruckpressung noch weiter entwässert werden kann, ohne daß wesentliche Substanzverluste an Torf während dieser Hochdruckpressung eintreten. Durch diese Anwendung der Hochdruckpressung im Anschluß an die mechanische Selbstabpressung koagulierten Rolltorfes wird in vielen Fällen, besonders bei schwierig zu entwässernden Torfarten, eine so weitgehende Entwässerung auf mechanischem Wege erzielt, daß die nachfolgende Trocknung der Preßlinge mit künstlich erzeugter Wärme wirtschaftlich durchgeführt werden kann. Ebenso ist es möglich, die Preßlinge künstlich anzutrocknen und dann zwecks Fertigtrocknung an der Luft zu stapeln und der Selbstverdichtung zu überlassen. Infolge der verlustfreien Doppelpressung bleiben nämlich die feinkolloiden Torfteilchen in dem Preßgut erhalten, so daß auch die nachfolgende Lufttrocknung sehr dichte Torfstücke liefert.It has now been shown that the peat pre-drained in this way can be dewatered even further in a high pressure pressure without essential Substance losses of peat occur during this high pressure pressing. Through this Use of high pressure pressing following mechanical self pressing Coagulated roll-up peat is used in many cases, especially when it is difficult to drain Types of peat, so extensive drainage achieved by mechanical means that the subsequent drying of the compacts with artificially generated heat is economical can be carried out. It is also possible to dry the compacts artificially and then stacked to air dry and self-compaction to leave. Because of the loss-free double pressing, the fine colloids remain Peat particles received in the pressed material, so that also the subsequent air drying provides very dense pieces of peat.
