Definitions
- the invention relates to a grate plate for a device for the thermal treatment of solids, preferably cement clinker emerging from a firing unit, the grate plate being box-shaped and having gas outlet slots for the gas supplied under the grate plate.
- a grate floor for receiving and conveying various bulk materials consists of several rows and several grate plates arranged side by side.
- the thermal material to be treated can be cold material that is treated with hot treatment gases or hot material that is cooled by the treatment gases. It is an essential feature that the grate plates are provided with gas outlet openings through which the gas supplied from below flows, which is required for the thermal treatment and conveying of the material.
- a grate floor is known from DE 33 32 592, the grate elements of which are made of two cast longitudinal webs with cast-on profiles that form the grate surface and alternate sprouts from each longitudinal web that extend transversely to the direction of conveyance, with fine slots for the treatment gas being formed by the joined longitudinal webs between these profiles are trained.
- the profiles forming the grate surface overlap one another and form obliquely upward slits in the direction of conveyance of the material.
- a grate floor is also known, which is formed by individual bars which are arranged in a box-shaped housing.
- the bars forming the grate floor are designed so that the gaps between the bars of the bar grate taper in the direction of flow of the cooling air in order to improve the conveying effect of the material through the gas flow.
- the rods have a triangular or trapezoidal cross section, or they are designed so that the gap between two rods is S-shaped.
- a step-shaped grate floor is known, on the vertical step side of which a slot is arranged through which a gas is periodically blown to convey the material.
- Box-shaped plates - according to DD 65438 - to which air is supplied from below have blow-out nozzles on their front sides.
- the plates are arranged in a staircase.
- a Gutueberleit designed for the discharged from a furnace outlet hot material is known, which is characterized in that it consists of a number of individual, transversely extending across the width of the inlet part, air-permeable support elements with their longitudinal edges together are connected and are arranged under a total inclination between 10 and 20.
- the support elements are provided with air passage openings in the direction of material conveyance.
- the object of the invention is to develop grate plates of the type described in the preamble of claim 1, which, while maintaining the basic shape of the grate plate and with little technical and economic effort, have a different design of the gas outlet, adapted to the thermal requirements and the conditions of the material.
- the grate surface on which the thermal treatment of the material takes place is formed by a plurality of grate plates arranged side by side to form a grate plate row and by a plurality of grate plate rows arranged in steps.
- the grate plate is box-shaped and has gas outlet slots for under the grate plate supplied gas.
- the grate plate bodies are arranged in the grate plate frame in such a way that several horizontal slots are arranged on the front side of the grate plate, as seen in the direction of conveyance of the material, in the manner of a terrace.
- the gap width of the horizontal slots is determined by the spacers cast onto the top of the grate plate body.
- the grate plate bodies used in the grate plates are designed differently in accordance with the required thermal conditions and the conveying behavior of the material. Rust plate bodies with an almost flat surface or rust plates are used, which, viewed in the direction of conveyance of the material, are provided with upward slants in the front area. Due to the different arrangement of differently designed grate plate bodies in a grate plate, the use of differently designed grate plates in a row of red plates and by changing the number of grate plate bodies while maintaining the basic shape of the grate plates, it is achieved that the gases with different gas quantities and at a different exit angle to the material be fed. In the edge area of the grate floor, where a low conveying effect of the material is required, grate plates with a small number of horizontal slots - i.e. with a few grate plate bodies - are used.
- the advantage of the grate plate according to the invention is that the path of the gas through the material layer is long due to the arrangement of the horizontal slots. This results in a good heat exchange between gas and material. At the same time, the horizontally supplied gases ensure good material conveyance. In addition, clogging of the slots due to material deposits or material diarrhea is avoided.
- the outflow velocity and the gas quantity as well as the outflow angle of the gas are influenced and can be adjusted according to the material conditions, rather the width and length of the grate floor, without having to change the basic shape of the grate plate.
- the invention is to be described on the basis of the use of the grate plates in a grate cooler for cooling hot cement clinker emerging from a firing unit.
- the invention can also be used for other solids and other thermal treatment processes in which rust floors consisting of rust plates are used.
- the grate surface of the grate cooler is formed by a plurality of grate plate rows arranged in steps, each grate plate row being formed from a plurality of grate plates 6 arranged next to one another.
- the basic structure of the grate plate 6 consists of a box-shaped grate plate frame 1, in which one or more grate plate bodies 2 are arranged.
- the Rostplattenkoerper 2 are inserted into the Rostplattenrahmen 1 that zz on the front of the material viewed in the direction of the material of the grate plates 6 offset several horizontal slots 3 arise.
- 2 spacers 4 are cast on the top of each of the grate plate bodies.
- the bottom grate plate body 2 is also part of the grate plate frame 1. However, its shape corresponds to that of the other grate plate body 2.
- the shape of the grate plate body 2 used is designed differently and depends on the conveying behavior and the cooling conditions of the material.
- the use of grate plate bodies 2 with an almost flat surface - as shown in FIG. 1 - ensures that the cooling air takes a longer time to flow through the material layer, for example compared to a cross flow. As a result, the exchange of heat between the cooling air and the hot material is more intensive. At the same time, blockage of the horizontal slots 3 by material is largely avoided.
- the outlet angle of the cooling air is influenced by using grate plate bodies 2, which are provided with an upward slant 5 in the front area, as seen in the transport direction of the material (FIG. 2).
- the angle of the inclines 5 is 10 to 40 and is dependent on the required gas outlet conditions.
- the number of grate plates 2 of a grate plate 6 can be between 1 and 7 and depends on the amount of air required.
- grate plates 6 with a small number of horizontal slots 3 are used, since in the edge area there is a smaller material layer thickness than in the middle area and thus a lower gas throughput is required.
- grate plates 6 with differently shaped grate plate bodies 2 are also used.
- grate plates 6 can be equipped with flat grate plate bodies 2 provided with a slope 4.

Abstract
Description
Die Erfindung betrifft eine Rostplatte fuer eine Vorrichtung zur thermischen Behandlung von Feststoffen, vorzugsweise von aus einem Brennaggregat austretenden Zementklinker, wobei die Rostplatte kastenfoermig ausgebildet ist und Gasaustrittsschlitze fuer das unter die Rostplatte zugefuehrte Gas besitzt.The invention relates to a grate plate for a device for the thermal treatment of solids, preferably cement clinker emerging from a firing unit, the grate plate being box-shaped and having gas outlet slots for the gas supplied under the grate plate.
So ist bekannt, dasz ein Rostboden zur Aufnahme und Befoerderung von verschiedenen schuettfaehigen Materialien aus mehreren Reihen und aus mehreren nebeneinander angeordneten Rostplatten besteht. Das thermisch zu behandelnde schuettfaehige Material kann dabei kaltes Material sein, welches mit heiszen Behandlungsgasen behandelt wird oder heiszes Material, das durch die Behandlungsgase gekuehlt wird. Wesentliches Merkmal dabei ist, dasz die Rostplatten mit Gasaustrittsoeffnungen versehen sind, durch die das von unten zugefuehrte Gas hindurchstroemt, das zur thermischen Behandlung und Foerderung des Materials benoetigt wird.It is known that a grate floor for receiving and conveying various bulk materials consists of several rows and several grate plates arranged side by side. The thermal material to be treated can be cold material that is treated with hot treatment gases or hot material that is cooled by the treatment gases. It is an essential feature that the grate plates are provided with gas outlet openings through which the gas supplied from below flows, which is required for the thermal treatment and conveying of the material.
Aus der DE 33 32 592 ist ein Rostboden bekannt, dessen Rostelemente aus jeweils zwei gegossenen Laengsstegen mit angegossenen die Rostoberflaeche bildenden, sich abwechselnd sprossenartig von jedem Laengssteg quer zur Foerderrichtung erstreckenden Profilen besteht, wobei durch die zusammengefuegten Laengsstege zwischen diesen Profilen feine Schlitze fuer das Behandlungsgas ausgebildet sind. Die die Rostoberflaeche bildenden Profile ueberlappen einander und bilden in Foerderrichtung des Materials schraeg nach oben verlaufende Luftschlitze.A grate floor is known from DE 33 32 592, the grate elements of which are made of two cast longitudinal webs with cast-on profiles that form the grate surface and alternate sprouts from each longitudinal web that extend transversely to the direction of conveyance, with fine slots for the treatment gas being formed by the joined longitudinal webs between these profiles are trained. The profiles forming the grate surface overlap one another and form obliquely upward slits in the direction of conveyance of the material.
Aus der DE 19 40 700 ist ebenfalls ein Rostboden bekannt, der durch einzelne Staebe gebildet wird, die in einem kastenfoermigen Gehaeuse angeordnet sind. Die den Rostboden bildenden Staebe sind dabei so gestaltet, dasz die Spalte zwischen den Staeben des Stabrostes sich in Stroemungsrichtung der Kuehlluft duesenartig verjuengen, um dadurch den Foerdereffekt des Materials durch den Gasstrom zu verbessern. Die Stabe weisen dabei einen dreieckigen oder trapezfoermigen Querschnitt auf, beziehungsweise sie sind so ausgebildelt, dasz der zwischen zwei Staeben entstehende Spalt S-foermig gewellt ist.From DE 19 40 700 a grate floor is also known, which is formed by individual bars which are arranged in a box-shaped housing. The bars forming the grate floor are designed so that the gaps between the bars of the bar grate taper in the direction of flow of the cooling air in order to improve the conveying effect of the material through the gas flow. The rods have a triangular or trapezoidal cross section, or they are designed so that the gap between two rods is S-shaped.
Aus der SU 398 808 ist ein stufenfoermig ausgebildeter Rostboden bekannt, an dessen vertikaler Stufenseite ein Schlitz angeordnet ist, durch den periodisch ein Gas zur Foerderung des Materials geblasen wird.From SU 398 808 a step-shaped grate floor is known, on the vertical step side of which a slot is arranged through which a gas is periodically blown to convey the material.
Kastenfoermig ausgebildete Platten - entsprechend DD 65438 -, denen von unten Luft zugefuehrt wird, besitzen an ihren Stirnseiten Ausblasdduesen. Dabei sind die Platten treppenfoermig angeordnet.Box-shaped plates - according to DD 65438 - to which air is supplied from below have blow-out nozzles on their front sides. The plates are arranged in a staircase.
Aus der DE 35 38 059 ist eine Gutueberleiteinrichtung fuer das aus einem Ofenauslauf ausgetragene heisze Material bekannt, die dadurch gekennzeichnet ist, dasz sie aus einer Anzahl von einzelnen, sich quer ueber die Breite des Einlaufteils erstreckenden, luftdurchlaessigen Tragelementen besteht, die mit ihren Laengsraendern miteinander verbunden sind und unter einer Gesamtneigung zwischen 10 und 20 angeordnet sind. Die Tragelemente sind in Foerderrichtung des Materials mit Luftdurchtrittsoeffnungen versehen.From DE 35 38 059 a Gutueberleiteinrichtung for the discharged from a furnace outlet hot material is known, which is characterized in that it consists of a number of individual, transversely extending across the width of the inlet part, air-permeable support elements with their longitudinal edges together are connected and are arranged under a total inclination between 10 and 20. The support elements are provided with air passage openings in the direction of material conveyance.
Diese aus den einzelnen Rostplatten gebildeten Rostboeden weisen als gemeinsames Merkmal auf, dasz die den Rostplatten von unten zugefuehrten Gase unter einem durch die Gestaltung der Rostplatten bestimmten Ausstroemwinkel durch die Materialschicht geleitet werden. Auf Grund der Verwendung von einheitlichen Guszformen fuer die Rostplatten ist es nicht moeglich, den Gasdurchtritt ueber die Breite bzw. ueber die Laenge des Rostbodens entsprechend den Erfordernissen fuer die thermischen Materialbehandlung und der Foerderung des Materials zu beeinflussen. Die verwendung von unterschiedlich gestalteten Rostplatten fuer eine Rastbahn wuerde eine erhebliche Verteuerung der Anlage zur Folge haben.These rust floors formed from the individual grate plates have as a common feature that the gases supplied to the grate plates from below are passed through the material layer at an outflow angle determined by the design of the grate plates. Due to the use of uniform molds for the grate plates, it is not possible to influence the gas passage over the width or over the length of the grate floor in accordance with the requirements for the thermal material treatment and the conveyance of the material. The use of differently designed grate plates for a rest stop would make the system considerably more expensive.
Die Aufgabe der Erfindung besteht darin, Rostplatten der im Oberbegriff des Anspruches 1 beschriebenen Art zu entwickeln, die bei Beibehaltung der Grundform der Rostplatte und bei einem geringen technischen und oekonomischen Aufwand eine den thermischen Erfordernissen und den Foerderbedingungen des Materials angepaszte unterschiedliche Gestaltung des Gasaustrittes aufweisen.The object of the invention is to develop grate plates of the type described in the preamble of
Diese Aufgabe wird erfindungsgemaesz durch die in den Patentanspruechen beschriebene Vorrichtung geloest. Die Rostoberflaeche, auf dem die thermische Behandlung des Materials erfolgt, wird gebildet durch mehrere nebeneinander angeordnete Rostplatten zu einer Rostplattenreihe und durch mehrere stufenfoermig angeordnete Rostplattenreihen .This object is achieved according to the invention by the device described in the claims. The grate surface on which the thermal treatment of the material takes place is formed by a plurality of grate plates arranged side by side to form a grate plate row and by a plurality of grate plate rows arranged in steps.
Die Rostplatte ist kastenfoermig ausgebildet und besitzt Gasaustrittsschlitze fuer das unter die Rostplatte zugefuehrte Gas. Erfindungsgemaesz sind dabei die Rostplattenkoerper so in den Rostplattenrahmen angeordnet, dasz an der in Foerderrichtung des Materials gesehenen Vorderseite der Rostplatte terrassenfoermig versetzt mehrere Horizontalschlitze angeordnet sind. Die Spaltweite der Horizontalschlitze wird durch die an der Oberseite der Rostplattenkoerper angegossene Abstandshalter bestimmt.The grate plate is box-shaped and has gas outlet slots for under the grate plate supplied gas. According to the invention, the grate plate bodies are arranged in the grate plate frame in such a way that several horizontal slots are arranged on the front side of the grate plate, as seen in the direction of conveyance of the material, in the manner of a terrace. The gap width of the horizontal slots is determined by the spacers cast onto the top of the grate plate body.
Die in die Rostplatten eingesetzten Rostplattenkoerper sind entsprechend den erforderlichen thermischen Bedingungen und dem Foerderverhalten des Materials verschiedenartig ausgebildet. Zum Einsatz kommen Rostplattenkoerper mit nahezu eben ausgebildeter Oberflaeche oder Rostplatten, die in Foerderrichtung des Materials gesehen im vorderen Bereich mit einer nach oben gerichteten Schraege versehen sind. Durch die unterschiedliche Anordnung von verschiedenartig gestalteten Rostplattenkoerpern in einer Rostplatte, des Einsatzes von unterschiedlich ausgefuehrten Rostplatten in einer Rotplattenreihe und durch Aenderung der Anzahl der Rostplattenkoerper unter Beibehaltung der Grundform der Rostplatten wird erreicht, dasz die Gase mit unterschiedlichen Gasmengen und unter einem unterschiedlichen Austrittswinkel dem Material zugefuehrt werden. Im Randbereich des Rostbodens, wo ein geringer Foerdereffekt des Materials benoetigt wird, werden Rostplatten mit einer geringen Anzahl von Horizontalschlitzen - also mit wenigen Rostplattenkoerpern - eingesetzt.The grate plate bodies used in the grate plates are designed differently in accordance with the required thermal conditions and the conveying behavior of the material. Rust plate bodies with an almost flat surface or rust plates are used, which, viewed in the direction of conveyance of the material, are provided with upward slants in the front area. Due to the different arrangement of differently designed grate plate bodies in a grate plate, the use of differently designed grate plates in a row of red plates and by changing the number of grate plate bodies while maintaining the basic shape of the grate plates, it is achieved that the gases with different gas quantities and at a different exit angle to the material be fed. In the edge area of the grate floor, where a low conveying effect of the material is required, grate plates with a small number of horizontal slots - i.e. with a few grate plate bodies - are used.
Der Vorteil der erfindungsgemaeszen Rostplatte besteht darin, dasz durch die Anordnung der Horizontalschlitze der Weg des Gases durch die Materialschicht lang ist. Das hat einen guten Waermetausch zwischen Gas und Material zur Folge. Gleichzeitig erfolgt durch die horizontal zugefuehrten Gase eine gute Foerderung des Materials. Auszerdem werden Verstopfungen der Schlitze durch Materialablagerungen bzw. Materialdurchfall vermieden.The advantage of the grate plate according to the invention is that the path of the gas through the material layer is long due to the arrangement of the horizontal slots. This results in a good heat exchange between gas and material. At the same time, the horizontally supplied gases ensure good material conveyance. In addition, clogging of the slots due to material deposits or material diarrhea is avoided.
Durch die unterschiedlich ausgebildete Form der einzelnen Rostplattenkoerper und durch die Moeglichkeit des Einsatzes von einer unterschiedlichen Anzahl von Rostplattenkoerpern in einer Rostplatte wird die Ausstroemgeschwindigkeit und die Gasmenge sowie der Ausstroemwinkel des Gases beeinfluszt und kann entsprechend den Materialbedingungen Lieber die Breite und Laenge des Rostbodens eingestellt werden, ohne dasz dabei die Grundform der Rostplatte veraendert werden musz.Due to the differently designed shape of the individual grate plate bodies and the possibility of using a different number of grate plate bodies in one grate plate, the outflow velocity and the gas quantity as well as the outflow angle of the gas are influenced and can be adjusted according to the material conditions, rather the width and length of the grate floor, without having to change the basic shape of the grate plate.

Die Erfindung soll anhand des Einsatzes der Rostplatten in einem Rostkuehler zur Kuehlung von aus einem Brennaggregat austretenden heiszen Zementklinker beschrieben werden.The invention is to be described on the basis of the use of the grate plates in a grate cooler for cooling hot cement clinker emerging from a firing unit.
Die Erfindung ist auch fuer andere Feststoffe und andere thermische Behandlungsverfahren einsetzbar, bei denen aus Rostplatten bestehende Rostboeden verwendet werden.The invention can also be used for other solids and other thermal treatment processes in which rust floors consisting of rust plates are used.
Die Rostoberflaeche des Rostkuehlers wird durch mehrere stufenfoermig angeordnete Rostplattenreihen gebildet, wobei jede Rostplattenreihe aus mehreren nebeneinander angeordneten Rostplatten 6 gebildet wird.The grate surface of the grate cooler is formed by a plurality of grate plate rows arranged in steps, each grate plate row being formed from a plurality of
Der Grundaufbau der Rostplatte 6 besteht aus einem kastenfoermig ausgebildeten Rostplattenrahmen 1, in dem ein oder mehrere Rostplattenkoerper 2 angeordnet sind. Dabei sind die Rostplattenkoerper 2 so in den Rostplattenrahmen 1 eingesetzt, dasz an der in Foerderrichtung des Materials gesehenen Vorderseite der Rostplatten 6 terrassenfoermig versetzt mehrere Horizontalschlitze 3 entstehen. Zur Einhaltung einer bestimmten Spaltweite der Horizontalschlitze 3 sind jeweils an der Oberseite der Rostplattenkoerper 2 Abstandshalter 4 angegossen. Der unterste Rostplattenkoerper 2 ist gleichzeitig Bestandteil des Rostplattenrahmens 1. Seine Form entspricht aber der der anderen Rostplattenkoerper 2.The basic structure of the
Die Form der zum Einsatz kommenden Rostplattenkoerper 2 ist unterschiedlich gestaltet und richtet sich nach dem Foerderverhalten und den Kuehlbedingungen des Materials. Durch den Einsatz von Rostplattenkoerpern 2 mit nahezu eben ausgebildeter Oberflaeche - wie in Figur 1 dargestellt - wird erreicht, dasz die Kuehlluft eine laengere Zeit zum Durchstroemen der Materialschicht wie beispielsweise gegenueber einer Querstroemung benoetigt. Dadurch ist der Waermetausch zwischen Kuehlluft und heiszem Material intensiver. Gleichzeitig wird eine Verstopfung der Horizontalschlitze 3 durch Material weitestgehend vermieden.The shape of the
Durch Einsatz von Rostplattenkoerpern 2, die in Transportrichtung des Materials gesehen im vorderen Bereich mit einer nach oben gerichteten Schraege 5 versehen sind (Figur 2), wird der Ausstrittswinkel der Kuehlluft beeinfluszt. Der Winkel der Schraege 5 betraegt 10 bis 40 und ist abhaengig von den benoetigten erforderlichen Gasaustrittsbedingungen. Die Anzahl der Rostplattenkoerper 2 einer Rostplatte 6 kann zwischen 1 und 7 betragen und richtet sich nach der benoetigten Luftmenge. Im Randbereich der Rostkuehleroberflaeche werden Rostplatten 6 mit einer geringen Anzahl von Horizontalschlitzen 3 eingesetzt, da im Randbereich gegenueber dem mittleren Bereich eine geringere Materialschichtdicke vorliegt und somit ein geringerer Gasdurchsatz benoetigt wird.The outlet angle of the cooling air is influenced by using
Entsprechend den Kuehlbedingungen und dem Materialtransport werden auch Rostplatten 6 mit unterschiedlich gestalteten Rostplattenkoerpern 2 eingesetzt. So koennen Rostplatten 6 mit ebenen und mit einer Schraege 4 versehenen Rostplattenkoerpern 2 ausgeruestet werden.Depending on the cooling conditions and the material transport,
