Description

Verfahren zum Trocknen fester Körper, insbesondere Kohle Die Erfindung bezieht sich auf ein Verfahren zum Trocknen fester Körper und bezweckt, diesen Vorgang insbesondere für bitumenhaltige Stoffe, z. B. Rohbraunkohle, möglichst günstig zu gestalten. Hierbei kann auch die Trocknung weitgehender und wirtschaftlicher durchgeführt werden als durch die bekannten Verfahren.Method of drying solid bodies, particularly coal The invention refers to a process for drying solid bodies and the purpose of this process especially for bituminous substances, e.g. B. raw lignite, as cheap as possible design. In this case, the drying can also be carried out more extensively and more economically are considered by the known methods.

Nach der Erfindung wird das feuchte Gut mit beheizten 'Wandungen eines Dampftrockners in unmittelbare Berührung gebracht; an deren anderer Seite sich niederschlagender Dampf vorüberstreicht, wobei annähernd die ganze zum Trocknen des Gutes notwendige Wärme durch den Heizdampf zugeführt wird. Gleichzeitig werden warme, indifferente Gase durch das Trockengut geleitet, die zur Aufnahme und Abführung der sich entwickelnden Dämpfe bestimmt sind.According to the invention, the moist material with heated 'walls is one Brought into direct contact with the steam dryer; on the other side it is more pronounced Steam sweeps past, almost all of which is necessary to dry the goods Heat is supplied by the heating steam. At the same time become warm, indifferent Gases passed through the dry material, which are used to absorb and discharge the developing Vapors are intended.

Bei dem neuen Verfahren wird daher im Gegensatz zu den bekannten eine Abkühlung der zur Dampfaufnahme bestimmten Gase möglichst vermieden. Diese Gase können die höchste für das bitumenhaltige Gut zulässige Temperatur haben und demgemäß auch eine der höheren Temperatur entsprechende größere Dampfmenge aufnehmen und abführen, wobei dank der Verwendung sauerstofffreier, indifferenter Gase die Gefahr der Entzündung des Trockengutes umgangen wird. Zweckmäßig wird zur Vorwärmung dieser Gase die kostenlos zur Verfügung stehende Abwärme des Betriebes verwendet.In the new method is therefore in contrast to the known one Cooling down of the gases intended to absorb steam is avoided as far as possible. These gases can have the highest temperature permissible for the bituminous material and accordingly also absorb a larger amount of steam corresponding to the higher temperature and dissipate, thanks to the use of oxygen-free, inert gases, the danger the ignition of the dry material is avoided. It is useful to preheat this Gases uses the waste heat available free of charge from the company.

Als Dampftrockner kann ein Röhrentrockner, ein Tellertrockner oder ein anderer Trockner beliebiger an sich bekannter Bauart Verwendung finden.A tube dryer, a plate dryer or another dryer of any type known per se can be used.
