Definitions
- the invention relates to a method for drying moist bulk material according to the preamble of claim 1.
- the invention further relates to a system for drying moist bulk material according to the preamble of claim 8.
- FIG. 1 Another method for drying wet bulk material.
- a layer of wet bulk material is moved by means of a conveyor belt through a drying chamber and dried therein.
- an upper part of the layer is removed and a lower part of the layer is separated by sieving into two partial layers. These two partial layers are applied to the conveyor belt at the beginning of the conveyor belt.
- This method also has the disadvantage that a higher energy requirement is required for drying.
- the object of the invention is to form a more economically advantageous method and an economically advantageous plant for drying moist bulk material.
- the object is achieved in particular with a method for drying moist bulk material, wherein the bulk material layered is conveyed and thereby exposed to a fluid flow, wherein the wet bulk material is deposited as a first layer on a flat conveyor and moved by the conveyor in a conveying direction, and wherein at least a second layer is applied to the first layer, so that an overall layer is formed, which at least comprises the first and second layers, and wherein an upper part of the total layer is removed as a dried bulk material, and wherein the remaining part of the total layer forms a pre-dried bulk material, which is separated into a coarser bulk material and a finer bulk material, and wherein the coarser bulk material is conveyed opposite to the conveying direction, and is applied as a second layer on the first layer, and wherein the second layer with respect to the first layer in the direction of the conveying direction spaced applied to the first layer.
- a system for drying moist bulk material comprising a planar conveying means movable in a conveying direction, comprising a first distributing device, which is designed to apply moist bulk material to the conveying means to form a flat first layer, and comprising a second distribution device configured to apply a coarser bulk material to the first layer to form a planar second layer, and comprising a first separation device arranged in the conveying direction at the end of the conveyor, the separation device being configured to form an upper part of a conveyor by removing at least the first and second layer formed total layer as a dried bulk material, wherein the remaining part of the total layer, which forms a pre-dried bulk material, a second separating device is supplied, wherein the second separating device is designed to separate the pre-dried bulk material into a coarser bulk material and a finer bulk material, and comprising a conveying device to supply the coarser bulk material of the second distribution device, wherein the second distribution device with respect to the first distribution device downstream and
- the still moist bulk material to be dried is deposited in a planar manner on a conveying device to form a first layer and passed therefrom through a drying fluid stream, the bulk material being divided into two or more partial streams having different particle sizes after a first passage through the drying fluid stream wherein at least a partial flow is conveyed opposite to the conveying direction and is deposited on the first layer, so that at least two layers of superimposed bulk material are formed, which are passed through the drying fluid stream.
- the partial flow is applied with respect to the first layer in the direction of the conveying direction spaced apart on the first layer, said distance is preferably at least 10% of the length of the conveying means of the conveyor.
- the layers are preferably deposited in such a way that the layer with the smallest particle size is deposited at the top.
- the layers of smaller particle size are applied to the conveying device in such a way that they remain on the conveying device over a shorter conveying length, in comparison with layers having a larger particle size. This is because layers of smaller particle size dry faster and therefore not so long through the to be dried Fluid flow must be promoted as layers with larger particle size, which must be exposed to the fluid to be dried longer flow.
- An advantage of the method according to the invention is therefore to save energy during drying and / or to achieve a more homogeneous moisture content of the dried bulk material which is removed by the drying installation according to the invention.
- At least one further layer with predried bulk material is thus applied to the first layer of moist bulk material, the further layer preferably having a larger particle size, and all layers being conveyed by the drying fluid stream.
- a plurality of further layers of predried bulk material are deposited on the first layer, the further layers having an increasingly smaller particle size towards the top. It can be produced by a corresponding number of distributing devices, which are arranged spaced apart in the direction of the conveyor device to deposit the bulk material on the conveyor, any number of layers, as required.
- the drying fluid preferably drying air
- This method has the advantage that the entire system for drying moist bulk material requires no long or no additional conveying device, so that the entire system has a shorter overall length. It is also possible to reliably dry different types of moist bulk material. In addition, the drying is very energy efficient. Another advantage of the method is to see that there is less dust in the exhaust air, as small dried particles are removed relatively quickly from the drying process.
- the inventive method thus enables energy-efficient and cost-effective drying of moist bulk material, wherein the drying system can also be made relatively short and thus can have a relatively short overall length.

Die Aufgabe wird weiter gelöst mit einer Anlage aufweisend die Merkmale von Anspruch 8. Die Ansprüche 9 bis 14 betreffen weitere, vorteilhafte Ausführungsformen.This object is achieved by a method comprising the features of
Die Aufgabe wird insbesondere gelöst mit einem Verfahren zum Trocknen von feuchtem Schüttgut, wobei das Schüttgut schichtartig gefördert wird und dabei einem Fluidstrom ausgesetzt wird, wobei das feuchte Schüttgut als eine erste Schicht auf einem flächigen Fördermittel abgelagert und vom Fördermittel in eine Förderrichtung bewegt wird, und wobei zumindest eine zweite Schicht auf die erste Schicht aufgebracht wird, sodass eine Gesamtschicht ausgebildet wird, welche zumindest die erste und zweite Schicht umfasst, und wobei ein oberer Teil der Gesamtschicht als ein getrocknetes Schüttgut abgetragen wird, und wobei der verbleibende Teil der Gesamtschicht ein vorgetrocknetes Schüttgut ausbildet, das in ein gröberes Schüttgut und ein feineres Schüttgut getrennt wird, und wobei das gröbere Schüttgut entgegengesetzt zur Förderrichtung gefördert wird, und als zweite Schicht auf die erste Schicht aufgebracht wird, und wobei die zweite Schicht bezüglich der ersten Schicht in Verlaufsrichtung der Förderrichtung beabstandet auf die erste Schicht aufgebracht wird.The object is achieved in particular with a method for drying moist bulk material, wherein the bulk material layered is conveyed and thereby exposed to a fluid flow, wherein the wet bulk material is deposited as a first layer on a flat conveyor and moved by the conveyor in a conveying direction, and wherein at least a second layer is applied to the first layer, so that an overall layer is formed, which at least comprises the first and second layers, and wherein an upper part of the total layer is removed as a dried bulk material, and wherein the remaining part of the total layer forms a pre-dried bulk material, which is separated into a coarser bulk material and a finer bulk material, and wherein the coarser bulk material is conveyed opposite to the conveying direction, and is applied as a second layer on the first layer, and wherein the second layer with respect to the first layer in the direction of the conveying direction spaced applied to the first layer.
Die Aufgabe wird weiter insbesondere gelöst mit einer Anlage zum Trocknen von feuchtem Schüttgut, umfassend ein flächiges, in eine Förderrichtung bewegliches Fördermittel, umfassend eine erste Verteilvorrichtung, welche ausgestaltet ist, um feuchtes Schüttgut unter Ausbildung einer flächigen ersten Schicht auf das Fördermittel aufzubringen, sowie umfassend eine zweite Verteilvorrichtung, welche ausgestaltet ist, um ein gröberes Schüttgut unter Ausbildung einer flächigen zweiten Schicht auf die erste Schicht aufzubringen, sowie umfassend eine erste Trennvorrichtung welche in Förderrichtung am Ende des Fördermittels angeordnet ist, wobei die Trennvorrichtung ausgestaltet ist, um einen oberen Teil einer durch zumindest die erste und zweite Schicht ausgebildeten Gesamtschicht als getrocknetes Schüttgut abzutragen, wobei der verbleibende Teil der Gesamtschicht, welcher ein vorgetrocknetes Schüttgut ausbildet, einer zweiten Trennvorrichtung zugeführt ist, wobei die zweite Trennvorrichtung ausgestaltet ist, um das vorgetrocknete Schüttgut in ein gröberes Schüttgut und ein feineres Schüttgut zu trennen, sowie umfassend eine Fördervorrichtung, um das gröbere Schüttgut der zweiten Verteilvorrichtung zuzuführen, wobei die zweite Verteilvorrichtung bezüglich der ersten Verteilvorrichtung in Förderrichtung nachgelagert und beabstandet ist.The object is further achieved, in particular, with a system for drying moist bulk material, comprising a planar conveying means movable in a conveying direction, comprising a first distributing device, which is designed to apply moist bulk material to the conveying means to form a flat first layer, and comprising a second distribution device configured to apply a coarser bulk material to the first layer to form a planar second layer, and comprising a first separation device arranged in the conveying direction at the end of the conveyor, the separation device being configured to form an upper part of a conveyor by removing at least the first and second layer formed total layer as a dried bulk material, wherein the remaining part of the total layer, which forms a pre-dried bulk material, a second separating device is supplied, wherein the second separating device is designed to separate the pre-dried bulk material into a coarser bulk material and a finer bulk material, and comprising a conveying device to supply the coarser bulk material of the second distribution device, wherein the second distribution device with respect to the first distribution device downstream and spaced apart in the conveying direction.
Beim erfindungsgemässen Verfahren wird das zu trocknende, noch feuchte Schüttgut unter Ausbildung einer ersten Schicht flächenförmig auf eine Fördervorrichtung abgelagert und von dieser durch einen trocknenden Fluidstrom geleitet, wobei das Schüttgut nach einem ersten Durchgang durch den trocknenden Fluidstrom in zwei oder mehrere Teilströme mit unterschiedlicher Partikelgrösse aufgeteilt wird, wobei zumindest ein Teilstrom entgegengesetzt zur Förderichtung gefördert wird und auf die erste Schicht abgelagert wird, sodass zumindest zwei Schichten von übereinander liegendem Schüttgut ausgebildet werden, die durch den trocknenden Fluidstrom geleitet werden. Der Teilstrom wird bezüglich der ersten Schicht in Verlaufsrichtung der Förderrichtung beabstandet auf die erste Schicht aufgebracht, wobei dieser Abstand vorzugsweise zumindest 10% der Länge des Fördermittels der Fördervorrichtung beträgt. Die Schichten werden vorzugsweise derart abgelagert, dass die Schicht mit kleinster Partikelgrösse zuoberst abgelagert wird. In einer bevorzugten Ausgestaltung werden die Schichten mit kleinerer Partikelgrösse derart auf die Fördervorrichtung aufgebracht, dass diese über eine geringere Förderlänge auf der Fördervorrichtung verbleiben, im Vergleich zu Schichten mit grösserer Partikelgrösse. Dies deshalb, weil Schichten mit kleinerer Partikelgrösse schneller trocknen und daher nicht so lange durch den zu trocknenden Fluidstrom gefördert werden müssen wie Schichten mit grösserer Partikelgrösse, welche länger dem zu trocknenden Fluidstrom ausgesetzt werden müssen. Ein Vorteil des erfindungsgemässen Verfahrens ist daher beim Trocknen Energie zu sparen und/oder eine homogenere Feuchte des getrockneten Schüttgutes, welches von der erfindungsgemässen Trocknungsanlage abgeführt wird, zu erreichen. Beim erfindungsgemässen Verfahren wird somit auf die erste Schicht von feuchtem Schüttgut zumindest eine weitere Schicht mit vorgetrocknetem Schüttgut aufgebracht, wobei die weitere Schicht vorzugsweise eine grössere Partikelgrösse aufweist, und wobei alle Schichten durch den trocknenden Fluidstrom gefördert werden. In einer besonders bevorzugten Ausführungsform werden eine Mehrzahl von weiteren Schichten von vorgetrocknetem Schüttgut auf die erste Schicht abgelagert, wobei die weiteren Schichten gegen oben eine zunehmend kleinere Partikelgrösse aufweisen. Es kann durch eine entsprechende Anzahl von Verteilvorrichtungen, die in Verlaufsrichtung der Fördervorrichtung gegenseitig beabstandet angeordnet sind um das Schüttgut auf der Fördervorrichtung abzulagern, eine beliebige Anzahl Schichten erzeugt werden, je nach Erfordernis. In einer bevorzugten Ausführungsform strömt das trocknende Fluid, vorzugsweise Trocknungsluft, von oben zuerst in das vorgetrocknete Schüttgut und gibt dabei einen Teil der Wärme ab, bevor die Trocknungsluft durch die erste Schicht mit noch feuchtem Schüttgut strömt. Dieses Verfahren weist den Vorteil auf, dass die gesamte Anlage zum Trocknen von feuchtem Schüttgut keine lange oder keine zusätzliche Fördervorrichtung erfordert, sodass die gesamte Anlage eine kürzere Baulänge aufweist. Es ist zudem möglich unterschiedlichste Arten von feuchtem Schüttgut zuverlässig zu trocknen. Zudem erfolgt das Trocknen sehr energieeffizient. Ein weiterer Vorteil des Verfahrens ist darin zu sehen, dass sich in der Abluft weniger Staub befindet, da kleine getrocknete Partikel relativ schnell aus dem Trocknungsprozess entfernt werden. Im Gegensatz dazu offenbart das Dokument
Das erfindungsgemässe Verfahren ermöglicht somit ein energieeffizientes und kostengünstiges Trocknen von feuchtem Schüttgut, wobei die Trocknungsanlage zudem relativ kurz ausgestaltet werden kann und somit eine relativ kurze Gesamtlänge aufweisen kann.The inventive method thus enables energy-efficient and cost-effective drying of moist bulk material, wherein the drying system can also be made relatively short and thus can have a relatively short overall length.
