Definitions
- the invention relates to a device for removing fluids and / or solids from a mixture of particulate materials with a container forming an annular process space with a plurality of cells separated by walls, comprising an inlet cell, intermediate cells and an outlet cell Introducing the mixture to be treated into the inlet chamber of the process chamber, a discharge device for discharging the treated mixture from the outlet cell of the process chamber, a fan device for supplying a first fluidizing agent, in particular in the form of superheated steam, from below into the process chamber through a distributor plate for producing a Fluidized bed in the process chamber, a heating device for processing the first fluidizing agent in the flow direction in front of the fan device, swirl blades for conditioning the flow in the container from the process chamber to the heating gs adopted and in part also to a steam outlet, and a dedusting device in the flow path between the process chamber and the heating device, wherein the dedusting dust to the outlet cell is feasible.
- a device is particularly suitable for drying bulk materials and materials from the food and feed
- Particles entrained by the steam are separated on the way from the process space to a (vapor) discharge using swirl-producing blades and a de-dusting device to then supply the dust-free steam to the process space after re-heating in a heating device via a distributor plate.
- Such facilities are for example from the EP 1 956 326 B1 .
- Object of the present invention is therefore to further develop the generic device such that it has a higher reliability.
- a clumping of material to be dried, ie the mixture of particulate materials, should be substantially avoided. So it should be improved overall flow of the device.
- FIGS. 1a and 1b show a device according to the invention in the form of a fluidized bed evaporator dryer 1000 with an insertion device 1 for introducing material to be dried in the form of pressed pulp in a container 21 which has a process space 23 in the region of its bottom 22. More specifically, the pulp is introduced into the process space 23 in which a fluidized bed 2 can be generated by flowing a superheated steam inflow floor 24 to dry the pulp. Dried pulp can then be discharged from the container 21 by means of a discharge device 3, while particles entrained by the vapor from the process space 23 are separated within the container 21, inter alia by means of a dust collector 4 above the fluidized bed 2.
- the vapor freed of particles finally passes in part to a steam outlet 5 and partly to a heating device to be reheated by means of a heater 6, so that it again with the interposition of a fan device or a blower 7 the process chamber 23 through the distributor plate 24 can be fed therethrough.
- a heating device to be reheated by means of a heater 6, so that it again with the interposition of a fan device or a blower 7 the process chamber 23 through the distributor plate 24 can be fed therethrough.
- walls 25 are arranged vertically aligned and extend substantially from an outer wall of the heater 6 to a wall of the container 21 to form cells between them in the process space 23.
- the walls 25 may extend down to the inflow base 24, but then have to have openings or form a space between them and the inflow base 24.
- the cells formed by the walls 25 are open at the top, so that the steam serving as the fluidizing agent flows through the cells from bottom to top and entrains the material or particles to be treated and optionally transports them to a downstream cell.
- the expansion cone 26 there is a reduction in the flow rate, which leads to a broadening of the flow of steam from the cells.
- the expansion cone 26 and an upper region 27 adjoining the same have no internals, ie they provide a free space in which, with the separation of particles, the flows spread out of the cells and at least partially intermix.
- superheated steam is blown into the upper region 27 via nozzles 34 and 35.
- Separated particles are discharged vertically along the wall in the expansion cone 26 via ribs 36, while the rest of the particles enter together with the steam in a central separator in the form of the dust collector 4 in the lid 28 of the container.
- the ribs 36 thereby ensure a deceleration of the particles, which promotes the deposition.
- the inner contour of the lid 28 is formed to deflect the flow.
- the separation of smaller particles takes place by flowing the particle vapor mixture into the dust collector 4. Finally, the separated dust passes through a dust cyclone 33 into an outlet cell 202 in the process space 23.
- the entry device 1 introduces the pulp to be treated into a first cell into the process space 23, which is referred to below as the inlet cell 201.
- the last cell or outlet cell 202 provided with the discharge device 3 is not or only to a small extent flowed through by the fluidizing agent, so that material entering the cell 202 from above or at the inlet bottom 24 reaches the bottom region and via the discharge device 3 , especially as in the EP 2 146 167 B1 described, can be removed.
- a process control according to the EP 2 457 649 A1 be used.
- the inserter 1 is arranged to introduce the pulp into the center of the inlet cell 201, at the level of the upper extensions of the fluidized bed 2, which is a lower installation than known devices. In addition, it ensures that the pulp loosens and preheated in the inlet cell 201 passes.
- it comprises a screw conveyor 400 with rotatable paddles 401, as in FIG. 2 shown.
- wet material that is to say pulp to be dried, is supplied and immediately supplied with steam from a first steam feed 403, and comminution of clumped pulp takes place by mechanical energy input of the rotating paddle 401.
- the pulp is also transported and again supplied with steam from second steam feeders 404 and 405 during the transport.
- the screw conveyor 400 is attached to the container 21 via a docking area 406 and causes the pulp to be preheated and released into the inlet cell 201 along with an excess amount of steam immediately escaping upwardly in the container 21.
- the inlet cell 201 preferably covers a larger area of the inflow bottom 24 than any of the remaining cells, so that the supplied pulp is brought into contact on an increased bottom area with an increased amount of steam, which again counteracts a clumping. Because in the inlet cell 201, the pulp is still the wettest. Doubling the size of the inlet cell 201 from the rest of the cell has been found to be particularly good.
- the flow from the inlet cell 201 to the outlet cell 202 is conditioned via a plurality of flow directors to further counteract agglomeration, as discussed below with reference to FIGS FIGS. 3a to 3c . 4a and 4b is described.
- An apron 300 bounds the annular process space 23 inwards.
- a steam supply pipe 301 opens above the inflow bottom 24 to supply, via nozzles 302, steam to at least a first quarter of the cells across the inflow tray 24, as in FIG FIG. 3a shown.
- the steam supply pipe 301 is disposed in the annular portion of the inlet cell 201 to provide there increasingly with transverse steam for loosening, since there also the pulp still carries the largest amount of water.
- guide plates 303 are disposed between the nozzles 302 to ensure the cross-flow in each cell. The nozzles 302 and the guide plates 303 thus provide flow directing members, with the addition of steam via the nozzles 302 in addition to heating and water evaporation from the pulp.
- the inflow base 24 and the skirt 300 are formed with perforated plates 304a, 304b and 305, respectively, for guiding the flow in a targeted manner.
- all the perforated plates 304a, 304b and 305 have holes for the passage of superheated steam, while some of these perforated plates, namely the perforated plates 304b and 305, also have unevennesses for guiding said vapor.
- the perforated plates 305 of the skirt 300 support a flow along the skirt 300 down to the inflow base 24, see the flow lines 310, while the perforated plates 304b support a flow along the flow lines 312 as an extension of the flow line 311, so that a circular flow in the fluidized bed 2 in essentially perpendicular to the distributor plate 24, namely from the skirt 300 via the distributor plate 24 back to the skirt 300 is forced.
- Another circular flow same direction of rotation is not shown by perforated plates with bumps in a direction of the open ends of the cells upwardly inclined floor extension, the one contacting the wall of the container 21 edge 307 according to FIG. 3b is forced, namely along the inflow base 24, the edge 307 and the wall back to the distributor plate 24th
- a transport region 306 which a horizontal circular path from the inlet cell 201 to the outlet 202 to the Promoting the pulp in the process space 23 ensures.
- the nozzles 302, guide plates 303 and perforated plates 304a, 304b and 305 may differ for each cell to account for the progressing drying of the pulp.
- the opening ratio of the perforated plates 304a to 305 from the inlet cell 201 to the outlet cell 202 becomes smaller.
- FIGS. 4a and 4b For example, a perforated plate 304b having a plurality of holes 341 and flakes 342 is shown. More specifically shows FIG. 4a an underside 343 on which the perforated plate 403b in the region of the flakes 342 each have a large opening for superheated steam, resulting in a bump on the top 344, the in FIG. 4b is shown, leads and thus can provide the superheated steam with a directional pulse.
- Many different geometric designs are conceivable; It is also conceivable that the in the FIGS. 3b and 3c shown flow lines 312 are not exactly radial, but are inclined in the direction of the flow lines 313, so as to serve a transport of the pulp.
- the fan 7, according to FIG. 1a is provided within a dished bottom 22 a of the bottom 22, serves to convey superheated steam from the heater 6, which is often referred to as the vapor stream and which allows fluidization in the fluidized bed 2.
- the need for vapors or drying vapors in the individual cells of the process space 23 is different, since the pulp to be dried from the inlet cell 201 in the direction of the outlet cell 202 loses moisture. Since the vapor stream enters the individual cells via the distributor plate 24 substantially in parallel via the fan 7, the vapor is distributed in accordance with the pressure loss which arises when the individual cells flow. This pressure loss is primarily influenced by the pressure loss of the inflow base 24 and the overlying mass of the fluidized bed 2.
- FIGS. 3a-3d can be influenced by targeted selection of the number, orientation and / or arrangement of the holes 341, the shed 342, the nozzles 302 and the guide plates 303, both the transport and the turbulence and thus drying.
- the holes 341 and flakes 342 in the perforated plates 304a, 304b, and 305 as well as the guide plates 303 are fixedly installed in the fluidized bed dryer 1000.
- an alternative construction will be described with reference to FIGS FIGS. 5a-5d described.
- FIG. 5a shows a plan view of a dished bottom 22'a of a second embodiment of a fluidized bed evaporator according to the invention, in addition to a fan 7 'a plurality of baffles 501 of a Nachleitapparats 500 are arranged, which serve the conditioning of the flow in the dished bottom 22'a, namely for guiding said flow radially outward as through the flow paths A in FIG. 5a shown.
- the Nachleitapparat 500 includes further baffles 502 and 503 with different orientations, as best in FIG. 5b which shows a partial perspective of the area below an inflow bottom 24 'within a bottom 22' with the dished bottom 22'a.
- FIG. 5b shows a partial perspective of the area below an inflow bottom 24 'within a bottom 22' with the dished bottom 22'a.
- 5b is also a Anströmm convincedstützglied 24'a shown, along which the conditioned by the Nachleitapparat 500 flow according to the flow path B rises, and either through openings in the substantially horizontally extending distributor plate 24 'or to the wall of the bottom 22' inclined edge 240 ' to get into the process room or in the area of the bottom 22 'below the inflow base 24' is circulated.
- the invention proposes adjustable baffles 600 in the region of the bottom 22 ', in particular into the dished bottom 22'a into, as in the FIGS. 5c and 5d shown.
- Each adjustable guide plate 600 is rotatable about an axis of rotation 601 via an adjusting device 602.
- the adjusting device 602 can be adjusted either manually in the case of the opening of the fluidized bed evaporator dryer according to the invention, or else from outside the fluidized bed evaporator, even in the drying operation thereof.
- adjustable baffles 700 can be arranged directly underneath the baffle bottom. This is in FIG. 6 in a perspective view, according to which are arranged substantially parallel to the distributor plate 24 "the adjustable baffles 700 in the area of Anströmm Camillstützgliedern 24" b, namely about an axis of rotation 701 rotatable, as indicated by the arrow F.
- the inflow base support members 24 "b are in turn supported by the inflow base support members 24" a, which are secured to the wall of the floor.
- FIGS. 7a and 7b namely, the flow path G or G 'through the individual openings in a distributor plate 24''' removable, which has an influence on the solids transport path H or H 'within the fluidized bed 2''' has.
- a flow path G performs according to Figure 7a due to its lower inclination to the inflow base 24 '''to increased transport within the fluidized bed 2''', while a flow path G 'according to FIG. 7b steeper passes through the inlet plate 24 '''and thus provides for an increased turbulence in the fluidized bed 2'".
- adjustable baffles 600 and 700 can be combined with special perforated plate designs as well as guide plates above the inflow floor. Such a combination provides a precise adjustment of the flow needed for the particular pulp to optimize drying from an inlet cell to an outlet cell.

Aus dem Stand der Technik sind eine Vielzahl von Vorrichtungen des genannten Typs bekannt, die in der Regel überhitzen Dampf als Fluidisierungsmittel einsetzen. Diese so genannten Wirbelschichtverdampfungstrockner werden eingesetzt, um Schüttgut bzw. partikelförmige Materialien von unten mit überhitztem Dampf zu durchströmen und zu fluidisieren, so dass eine Wirbelschicht entsteht. Das zu behandelnde Material wird dabei von einer Eintragszelle, in der das zu behandelnde Material in den Behälter und den Prozessraum eingeführt wird, über nachfolgende Verfahrenszellen bis zu einer Austragszelle gefördert. In der Austragszelle findet keine Anströmung von unten statt, so dass am unteren Ende der Austragszelle das fertig behandelte Material ausgetragen werden kann, beispielsweise über eine Austragsschnecke. Der Behälter ist an dem Austragsende ebenso wie an der Eintragseinrichtung über eine Schleuseneinrichtung abgedichtet, um den Bearbeitungsprozess unter Überdruck ablaufen lassen zu können. Vom Dampf mitgerissene Partikel werden auf dem Weg vom Prozessraum zu einem (Dampf)Ablass unter Einsatz von Drall erzeugenden Schaufeln und einer Entstaubungseinrichtung abgetrennt, um dann den vom Staub befreiten Dampf dem Prozessraum nach erneuter Erhitzung in einer Erhitzungseinrichtung über einen Anströmboden zuzuführen. Solche Einrichtungen sind z.B. aus der
Bei den bekannten Vorrichtungen kann es zu unzulässigen Materialansammlungen oder Klumpen im Bereich des Materialeintrags kommen, was schlimmstenfalls zu einem Totalausfall der Vorrichtung führen kann. Zur Behebung einer Verstopfung im Prozessraum muss nämlich die Vorrichtung ausgeschaltet werden, drucklos gemacht und abgekühlt werden, um dann mit Schaufeln oder dergleichen händisch die Verstopfung aufzuheben.In the known devices may lead to inadmissible accumulation of material or lumps in the field of material entry, which in the worst case can lead to a total failure of the device. To remedy a blockage in the process room namely the device must be turned off, depressurized and cooled, and then manually pick up the blockage with shovels or the like.
Aufgabe der vorliegenden Erfindung ist es daher, die gattungsgemäße Vorrichtung derart weiterzuentwickeln, dass sie eine höhere Betriebssicherheit aufweist. Insbesondere soll eine Verklumpung von zu trocknendem Gut, also dem Gemenge partikelförmiger Materialien, im wesentlichen vermieden werden. Es soll also insgesamt der Durchfluss der Vorrichtung verbessert werden.Object of the present invention is therefore to further develop the generic device such that it has a higher reliability. In particular, a clumping of material to be dried, ie the mixture of particulate materials, should be substantially avoided. So it should be improved overall flow of the device.

Oberhalb des Anströmbodens 24 sind Wände 25 vertikal ausgerichtete angeordnet und erstrecken sich im wesentlichen von einer Außenwandung des Erhitzers 6 bis an eine Wandung des Behälters 21, um Zellen zwischen sich im Prozessraum 23 auszubilden. Die Wände 25 können bis zum Anströmboden 24 hinunter reichen, müssen dann aber Öffnungen aufweisen, oder einen Freiraum zwischen sich und dem Anströmboden 24 ausbilden. Die durch die Wände 25 gebildeten Zellen sind oben offen, so dass der als das Fluidisierungsmittel dienende Dampf von unten nach oben durch die Zellen hindurchströmt und das zu behandelnde Material oder Partikel mitreißt und ggf. in eine nachgeordnete Zelle transportiert.Above the
Es findet eine erste Drallerzeugung zwischen dem Prozessraum 23 und einem Erweiterungskonus 26 über Schaufeln 29 oberhalb der Wände 25 statt. Dadurch wird die vertikale Strömung des Dampfes im Prozessraum 23 umgelenkt, um zu einer Drallströmung im Erweiterungskonus 26 zu führen. Durch die Drallbeaufschlagung wird der Dampf samt damit mitgerissenen Partikeln also auf die Wandung des Behälters 21 gerichtet, wodurch es zu einer Abbremsung der Partikel kommt, nämlich durch Wandreibung, so dass die abgebremsten Partikel dann entlang der Wandung in den Prozessraum 23 zurückfallen.There is a first swirl generation between the
In dem Erweiterungskonus 26 kommt es zu einer Verringerung der Strömungsgeschwindigkeit, was zu einer Verbreiterung der Dampfströmung aus den Zellen führt. Der Erweiterungskonus 26 und ein sich an denselben anschließender oberer Bereich 27 weisen keine Einbauten auf, stellen also einen Freiraum dar, in dem sich unter Abtrennung von Partikeln die Strömungen aus den Zellen aufspreizen und sich zumindest teilweise vermischen. Zur Übertragung kinetischer Energie zwecks Verbesserung der Vermischung von Strömungsschichten mit unterschiedlichen thermischen Zuständen wird überhitzter Dampf in den oberen Bereich 27 über Düsen 34 und 35 eingeblasen. Abgetrennte Partikel werden längs der Wandung im Erweiterungskonus 26 über Rippen 36 vertikal abgeführt, während der Rest der Partikel gemeinsam mit dem Dampf in einen Zentralabscheider in Form des Staubkollektors 4 im Deckel 28 des Behälters eintritt. Die Rippen 36 sorgen dabei für eine Abbremsung der Partikel, was das Abscheiden fördert. Die Innenkontur des Deckels 28 ist zur Umlenkung der Strömung ausgeformt.In the
Nach Vorabscheidung von Partikeln im Freiraum erfolgt die Abscheidung von kleineren Partikeln durch Einströmen des Partikel-Dampfgemisches in den Staubkollektor 4. Schließlich gelangt der abgeschiedene Staub über einen Staubzyklon 33 in eine Auslasszelle 202 im Prozessraum 23.After pre-separation of particles in the free space, the separation of smaller particles takes place by flowing the particle vapor mixture into the
Die Eintragseinrichtung 1 trägt die zu behandelnde Pulpe in eine erste Zelle in den Prozessraum 23 ein, die im Folgenden als Einlasszelle 201 bezeichnet wird. Die mit der Austragseinrichtung 3 versehene letzte Zelle bzw. Auslasszelle 202 wird nicht oder nur in einem geringen Maße von dem Fluidisierungsmittel durchströmt, so dass von oben oder an dem Anströmboden 24 entlang in diese Zelle 202 eintretendes Material in den Bodenbereich gelangt und über die Austragseinrichtung 3, insbesondere wie in der
Die Eintragseinrichtung 1 ist derart angeordnet, dass sie die Pulpe in die Mitte der Einlasszelle 201, in Höhe der oberen Ausläufer der Wirbelschicht 2 einbringt, was gegenüber bekannten Vorrichtungen einen niedrigeren Einbau darstellt. Zudem sorgt sie dafür, dass die Pulpe aufgelockert und vorerwärmt in die Einlasszelle 201 gelangt. Dazu umfasst sie einen Schneckenförderer 400 mit rotierbaren Paddeln 401, wie in
Der Schneckenförderer 400 ist über einen Andockbereich 406 an dem Behälter 21 angebracht und sorgt dafür, dass die Pulpe vorerwärmt und gelockert zusammen mit einer Überschußmenge an Dampf, der sofort nach oben im Behälter 21 entweicht, in die Einlasszelle 201 eingeführt wird. Die Einlasszelle 201 überdeckt vorzugsweise eine größere Fläche des Anströmbodens 24 als jede der restlichen Zellen, so dass die zugeführte Pulpe auf einem vergrößerten Bodenbereich mit einer vergrößerten Dampfmenge in Kontakt gebracht wird, was auch wieder einer Verklumpung entgegen wirkt. Denn in der Einlasszelle 201 ist die Pulpe noch am feuchtesten. Eine Verdopplung der Größe der Einlasszelle 201 gegenüber den restlichen Zelle hat sich als besonders gut herausgestellt.The
Die Strömung von der Einlasszelle 201 zu der Auslasszelle 202 wird über eine Vielzahl von Strömungsleitgliedern konditioniert, um einer Verklumpung weiter entgegenzuwirken, wie im Anschluss mit Bezug auf die
Eine Schürze 300 begrenzt den ringförmigen Prozessraum 23 nach innen. Zwischen der Schürze 300 und dem Erhitzer 6 mündet ein Dampfzufuhrrohr 301 oberhalb des Anströmbodens 24, um über Düsen 302 Dampf zumindest einem ersten Viertel der Zellen quer über den Anströmboden 24 zuzuleiten, wie in
Der Anströmboden 24 und die Schürze 300 sind mit Lochblechen 304a, 304b bzw. 305 ausgebildet, um die Strömung gezielt zu führen. Alle Lochbleche 304a, 304b und 305 weisen dabei Löcher für einen Durchtritt von überhitztem Dampf auf, während einige dieser Lochbleche, nämlich die Lochbleche 304b und 305, zudem auch Unebenheiten zum Führen besagten Dampfes aufweisen. Dadurch unterstützen die Lochbleche 305 der Schürze 300 eine Strömung entlang der Schürze 300 herunter zum Anströmboden 24, siehe die Strömungslinien 310, während die Lochbleche 304b eine Strömung entlang der Strömungslinien 312 als Verlängerung der Strömungslinie 311 unterstützen, so dass eine Kreisströmung in der Wirbelschicht 2 im wesentlichen senkrecht zu dem Anströmboden 24, nämlich von der Schürze 300 über den Anströmboden 24 zurück zur Schürze 300 erzwungen wird. Eine weitere Kreisströmung gleicher Drehrichtung wird durch nicht gezeigte Lochbleche mit Unebenheiten in einer in Richtung der offenen Enden der Zellen nach oben geneigten Bodenverlängerung, die einen die Wandung des Behälters 21 kontaktierenden Rand 307 gemäß
Zwischen dem Lochblech 304b und dem Rand 307 und somit zwischen den beiden vertikalen, gleichsinnigen Kreisströmungen verläuft ein Transportbereich 306, der eine horizontale Kreisbahn von der Einlasszelle 201 zu der Auslasszelle 202 zur Förderung der Pulpe in dem Prozessraum 23 sicherstellt. Erfindungsgemäß liegt also ein durchgehender Transportweg der Pulpe im Prozessraum 23 durch Beaufschlagung mit horizontalen Transportimpulsen in Richtung des Austragebereichs, siehe Strömungslinien 313, vor, während zumindest über das erste Viertel des Prozessraums 23 eine Verwirbelung mit 2 gleichsinnig zirkulierenden Wirbeln pro Zelle erzwungen wird, was den Materialfluss im Prozessraum 23 homogenisiert und die Trocknung verbessert.Between the
Die Düsen 302, Führungsbleche 303 und Lochbleche 304a, 304b und 305 können sich für jede Zelle unterscheiden, um der voranschreitenden Trocknung der Pulpe Rechnung zu tragen. So wird das Öffnungsverhältnis der Lochbleche 304a bis 305 von der Einlasszelle 201 zur Auslasszelle 202 kleiner.The
Die
Der Ventilator 7, der gemäß
Die Pulpe muss nicht nur im Prozessraum 23 getrocknet werden, sondern gleichzeitig zur Trocknung muss sie auch von der Einlasszelle 201 zur Auslasszelle 202 transportiert werden. Bei dem Ausführungsbeispiel der
Es ist überraschender Weise festgestellt worden, dass die durch den Nachleitapparat 500 unterhalb des Anströmbodens 24' erzwungene Drallströmung im Prozessraum einen erheblichen Einfluss auf den Feststofftransport hat. Um diesen Feststofftransport gezielt beeinflussen zu können, wird erfindungsgemäß vorgeschlagen, verstellbare Leitbleche 600 im Bereich des Bodens 22', insbesondere bis in den Klöpperboden 22'a hinein, vorzusehen, wie in den
Alternativ zu den verstellbaren Leitblechen 600 oder selbst kumulativ dazu können direkt unterhalb des Anströmbodens weitere verstellbare Leitbleche 700 angeordnet sein. Dies ist in
Anhand der
Selbstverständlich sind die verstellbaren Leitbleche 600 bzw. 700 kombinierbar mit speziellen Lochblechgestaltungen sowie auch Führungsblechen oberhalb des Anströmbodens. Solch eine Kombination eröffnet eine genaue Einstellung der für die jeweilige Pulpe benötigten Strömung zwecks Optimierung der Trocknung von einer Einlasszelle zu einer Auslasszelle.Of course, the
