Description

Schüttgutkühler zum Kühlen von heißem Kühlgut Bulk cooler for cooling hot chilled goods
B E S C H R E I B U N GDESCRIPTION
Die Erfindung betrifft einen Schüttgutkühler mit einem das abzukühlende Kühlgut wie z. B. heißen Zementklinker tragenden von Kühlluft durchströmten feststehenden Kühlrost, wobei oberhalb der feststehenden Rostfläche quer zur Kühlguttransportrichtung mehrere Reihen benachbarter hin- und herbeweglicher balkenförmiger Schubelemente angeordnet sind, die zwischen einer Vorhubposition in Kühlguttransportrichtung und einer Rückhubposition bewegbar sind und die das Kühlgut vom Kühleranfang sukzessive zum Kühlerende transportieren.The invention relates to a bulk cooler with a refrigerated goods such as. B. hot cement clinker carrying cooling air flowed through by cooling air, wherein above the fixed grate surface transverse to the refrigerated goods transport direction several rows of adjacent reciprocating bar-shaped thrust elements are arranged, which are movable between a forward stroke position in the refrigerated goods transport direction and a return stroke position and which successively move the refrigerated goods from the beginning of the cooler to Transport the cooler end.
Bei einer Zementklinkerproduktionslinie wird der in einem Drehrohrofen aus caiciniertem Zementrohmehl erbrannte heiße Zementklinker aus dem Ofenaustragsende auf einen Kühler, in der Regel auf den Kühlrost eines Rostkühlers abgeworfen, auf diesem verteilt und durch geeignete Fördermittel in Längsrichtung zum Kühleraustragsende bewegt, wobei gleichzeitig der Kühlrost und die heiße Schüttgutschicht quer zur Förderrichtung im wesentlichen von unten nach oben von Kühlluftströmungen durchsetzt werden.In a cement clinker production line, the hot cement clinker produced in a rotary kiln from caicinated cement raw meal is thrown from the end of the furnace discharge onto a cooler, usually onto the cooling grate of a grate cooler, distributed thereon and moved in the longitudinal direction to the cooler discharge end by suitable conveying means, the cooling grate and the hot bulk material layer transverse to the direction of conveyance are essentially traversed by cooling air flows from bottom to top.
Bei einem konventionellen Schubrostkühler wechseln sich in Förderrichtung gesehen ortsfeste Rostplattenreihen mit hin- und herbeweglichen Rostplattenreihen ab, und durch gemeinsam oszillierende Bewegung aller beweglichen Rostplattenreihen wird das zu kühlende heiße Gut schubweise transportiert und dabei gekühlt. Um das Verschleißproblem eines Schubrostkühlers insbesondere im Überlappungsbereich benachbarter bewegter und nicht bewegter Rostplattenreihen zu umgehen, ist aus der EP-B-1 021 692 ein Rostkühlertyp bekannt, bei dem der von Kühlluft durchströmte Kühlrost nicht bewegt wird, sondern feststeht, wobei oberhalb der feststehenden Rostfläche quer zur Kühlguttransportrichtung mehrere Reihen benachbarter hin- und herbeweglicher balkenförmiger Schubelemente angeordnet sind, die zwischen einer Vorhubposition in Kühlguttransportrichtung und einer Rückhubposition bewegt werden, so dass durch die Hin- und Herbewegung dieser Schubelemente im abzukühlenden Gutbett das Gutmaterial vom Kühleranfang zum Kühlerende schrittweise bewegt und dabei gekühlt wird. Dabei ist es bei einem ähnlichen aus der DE-A-100 18 142 bekannten Rostkühlertyp noch bekannt, die oberhalb des feststehenden Kühlrostbodens bewegli- chen Schubelemente in wenigstens zwei Gruppen aufzuteilen und die Schubelemente gemeinsam nach vorne in Transportrichtung zu bewegen, aber nicht gemeinsam, sondern getrennt voneinander wieder zurück zu bewegen, wobei möglichst wenig Schüttgutbettmaterial beim Rückwärtsschub der Schubelemente zurückbewegt werden soll. Allerdings sind die in der z. B. 1000° C heißen Zementklinkerschüt- tung bewegten Schubelemente einer hohen thermisch-mechanischen Verschleißbeanspruchung ausgesetzt, wodurch die Standzeit des Rostkühlers verkürzt wird.In a conventional moving grate cooler, stationary grate plate rows alternate with reciprocating grate plate rows in the conveying direction, and the hot material to be cooled is transported in batches and cooled by the oscillating movement of all movable grate plate rows. In order to avoid the wear problem of a sliding grate cooler, in particular in the overlap area of adjacent moving and non-moving grate plate rows, EP-B-1 021 692 discloses a grate cooler type in which the cooling grate through which cooling air flows is not moved, but is fixed, above the fixed grate surface Transversely to the refrigerated goods transport direction, several rows of adjacent reciprocating bar-shaped thrust elements are arranged, which are moved between a forward stroke position in the refrigerated goods transport direction and a return stroke position, so that the material to be cooled gradually moves from the cooler start to the cooler end by the back and forth movement of these push elements is cooled. In a similar grate cooler type known from DE-A-100 18 142, it is also known to divide the push elements movable above the fixed cooling grate bottom into at least two groups and to move the push elements forward together in the transport direction, but not together, but instead to move back separately from each other, with as little bulk material as possible being moved back when the push elements are pushed backwards. However, the z. B. 1000 ° C hot cement clinker fill moving thrust elements exposed to high thermal-mechanical wear, which shortens the life of the grate cooler.
Der Erfindung liegt die Aufgabe zugrunde, einen Schüttgutkühler insbesondere für heißen Zementklinker mit feststehendem belüfteten Kühlrost und bewegten Schubelementen und dennoch mit erhöhter Standzeit zu schaffen.The invention has for its object to provide a bulk cooler, in particular for hot cement clinker with a fixed ventilated cooling grate and moving thrust elements and yet with an increased service life.
Diese Aufgabe wird gemäß der Erfindung mit einem Schüttgutkühler mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Beim erfindungsgemäßen Schüttgutkühler sind die oberhalb der feststehenden mit Kühlluft durchsetzten Rostfläche beweglichen Schubelemente als Hohlkörper ausgebildet und von einem Kühlmedium durchströmt und sie werden dabei von innen gekühlt. Das Kühlmedium kann dabei Kühlluft sein, z. B. ein Teil der im Rostkühler eingesetzten Kühlluft, die über Kühllufteintrittsöffnungen im unteren Bereich der Schubelemente in diese einströmt und über Kühlluftaus- trittsöffnungen im oberen Bereich der Schubelemente ausströmt und anschließend im Schüttgutbett als zusätzliche Kühlluft genutzt wird. Als Kühlmedium kann auch Wasser eingesetzt und dessen Verdampfungswärme zur Kühlung der Schubelemente genutzt werden, wobei der aus den Schubelementen austretende Wasserdampf sich mit der Kühlluft des Schüttgutkühlers vermischt.This object is achieved according to the invention with a bulk material cooler with the features of claim 1. Advantageous developments of the invention are specified in the subclaims. In the case of the bulk material cooler according to the invention, the thrust elements which are movable above the fixed grate surface through which cooling air passes are designed as hollow bodies and a cooling medium flows through them and they are cooled from the inside. The cooling medium can be cooling air, for. B. part of the cooling air used in the grate cooler, which flows into the lower area of the thrust elements via cooling air inlet openings and flows out through cooling air outlet openings in the upper area of the thrust elements and is then used in the bulk material bed as additional cooling air. Water can also be used as the cooling medium and its heat of evaporation can be used to cool the thrust elements, the water vapor emerging from the thrust elements being mixed with the cooling air of the bulk material cooler.
Jedenfalls ist beim erfindungsgemäßen Schüttgutkühler infolge der effizienten Kühlung der hoch beanspruchten Schubelemente die Standzeit erhöht, was von besonderer Bedeutung für eine Zementklinkerproduktionslinie ist, die bei einem vorzeitigen Ausfall des Klin- kerrostkühlers stillgesetzt werden muss.In any case, the service life of the bulk material cooler according to the invention is increased as a result of the efficient cooling of the highly stressed thrust elements, which is of particular importance for a cement clinker production line which has to be stopped in the event of a premature failure of the clinker rust cooler.
Die Erfindung und deren weitere Merkmale und Vorteile werden anhand des in der Zeichnung schematisch dargestellten Ausführungsbeispieles näher erläutert.The invention and its further features and advantages are explained in more detail with reference to the exemplary embodiment shown schematically in the drawing.
Die Zeichnung zeigt den Querschnitt durch einen erfindungsgemäßen Rostkühler mit einem von Kühlluft 10 im wesentlichen von unten nach oben durchströmten feststehenden, d. h. nicht bewegten Kühlrost 11 , über den das nicht dargestellte abzukühlende Kühlgut wie z. B. hei- ßer Zementklinker senkrecht zur Zeichnungsebene vom Kühlguteintritt zum Kühlgutaustritt bewegbar ist. Der Kühlrost 11 kann aus einzelnen Modulen zusammengesetzt sein, die mit Vorteil mit Kühlgut- mulden bzw. Kühlguttaschen 12 zur Aufnahme und zum Festhalten von Kühlgut ausgestattet sind, so dass beim Betrieb des Rostkühlers auf dem statischen Kühlrost 1 1 eine untere vorgekühlte Gutbettlage bzw. Schutzlage gebildet wird.The drawing shows the cross section through a grate cooler according to the invention with a fixed, ie non-moving cooling grate 11 through which cooling air 10 flows essentially from the bottom upwards, via which the items to be cooled, not shown, such as, for example, B. hot cement clinker is movable perpendicular to the plane of the drawing from the refrigerated goods inlet to the refrigerated goods outlet. The cooling grate 11 can be composed of individual modules, which are advantageously troughs or refrigerated goods pockets 12 are equipped for receiving and holding refrigerated goods, so that when the grate cooler is operating on the static cooling grate 11, a lower pre-cooled good bed layer or protective layer is formed.
Oberhalb des Kühlrostes 1 1 sind quer zu der senkrecht zur Zeichnungsebene verlaufenden Kühlguttransportrichtung mehrere Reihen mit Abstand benachbarter Schubelemente 13a, 13b, 13c usw. angeordnet, deren balkenförmigen Oberseiten von unten in das nicht dar- gestellte z. B. 1000° C heiße Kühlgutbett hineinragen. Diese Schubelemente werden von unterhalb des Kühlrostes 11 angetrieben und zwar so, dass sie gemeinsam senkrecht zur Zeichnungsblattebene nach vorn zu einer Vorhubposition in Kühlguttransportrichtung bewegt und gemeinsam oder zeitlich voneinander getrennt wieder zurückbe- wegt werden, wodurch das Kühlgut sukzessive vom Kühleranfang zum Kühlerende transportiert wird.Above the cooling grate 11, several rows are arranged transversely to the refrigerated goods transport direction perpendicular to the plane of the drawing, with spacing between adjacent thrust elements 13a, 13b, 13c, etc., whose bar-shaped upper sides from below into the z. B. 1000 ° C hot refrigerated goods protrude into it. These thrust elements are driven from below the cooling grate 11 in such a way that they are moved forward perpendicularly to the plane of the drawing sheet to a forward stroke position in the direction of the goods to be transported and are moved back together or at different times, so that the goods to be cooled are successively transported from the beginning of the cooler to the end of the cooler.
Die der hohen thermisch-mechanischen Verschleißbeanspruchung ausgesetzten Schubelemente 13a bis 13c sind erfindungsgemäß als Hohlkörper ausgebildet und sie werden von Kühlluft durchströmt und dabei von innen gekühlt, wodurch die Standzeit der Schubelemente und damit die Standzeit des Schüttgutkühlers erhöht werden. Dazu sind die Schubelemente 13a bis 13c etc. in ihrem unteren unterhalb des Kühlrosts 11 befindlichen Bereich jeweils mit Kühllufteintrittsöff- nungen 14 und an ihrer Oberseite mit Kühlluftaustrittsöffnungen 15 versehen, wobei pro balkenförmigem Schubelement auch mehrere brausenartig verteilte Kühlluftaustrittsöffnungen 15 angeordnet sein können. Die aus dem oberen Bereich der Schubelemente 13a bis 13c etc. austretende Kühlluft tritt dann in das Schüttgutbett zu dessen Kühlung ein. Bei Rostkühlern lassen sich Ungleichverteilungen im heißen Schüttgutbett hinsichtlich Schüttgutbetthöhe, Klinkerkorngröße, Temperaturprofil etc. nicht immer vermeiden, wodurch sich eine ungleichmäßige Kühlung ergibt. Daher können beim erfindungsgemäßen Rost- kühler die Schubelemente 13a bis 13c etc. individuell einzeln und/oder in wählbaren Gruppen zwischen ihrer Vorhubposition und ihrer Rückhubposition gesteuert bewegt werden, um die Fördereigenschaften des Rostkühlers sowie die Verteilung des Zementklinkers sowohl über die Kühlerlänge als auch über die Kühlerbreite optimie- ren zu können, so dass beim erfindungsgemäßen Rostkühler abgesehen von seiner hohen Standzeit auch der thermische Wirkungsgrad hoch gehalten werden kann. Denn beim erfindungsgemäßen Rostkühler wird grundsätzlich ermöglicht, den heißen Zementklinker in bestimmten Bereichen bzw. Zonen des Kühlers gezielt zu verteilen, zu beschleunigen oder zu bremsen. The thrust elements 13a to 13c, which are exposed to the high thermal-mechanical wear stress, are designed as hollow bodies according to the invention and are flowed through by cooling air and thereby cooled from the inside, thereby increasing the service life of the thrust elements and thus the service life of the bulk material cooler. For this purpose, the thrust elements 13a to 13c etc. are each provided with cooling air inlet openings 14 in their lower area below the cooling grate 11 and on their upper side with cooling air outlet openings 15, it being possible for several beam-like distributed cooling air outlet openings 15 to be arranged per beam-shaped pushing element. The cooling air emerging from the upper region of the thrust elements 13a to 13c etc. then enters the bulk material bed for cooling it. In the case of grate coolers, uneven distributions in the hot bulk material bed with regard to the bulk material bed height, clinker grain size, temperature profile etc. cannot always be avoided, which results in uneven cooling. Therefore, in the grate cooler according to the invention, the thrust elements 13a to 13c etc. can be moved individually and / or in selectable groups between their forward stroke position and their return stroke position in order to control the conveying properties of the grate cooler and the distribution of the cement clinker both over the cooler length and over the To be able to optimize the cooler width, so that in the grate cooler according to the invention, apart from its long service life, the thermal efficiency can also be kept high. Because with the grate cooler according to the invention it is fundamentally possible to specifically distribute, accelerate or brake the hot cement clinker in certain areas or zones of the cooler.
