Description

Die Erfindung betrifft eine Vorrichtung zur Entstaubung staubbeladener Gase mittels als Wirbelkammer ausgebildeter Hochleistungsstaubabscheider, die parallel geschaltet an einen Rohgaskanal angeschlossen und mit Reingassammelkanälen sowie Staubabscheidekanälen verbunden sind.The invention relates to a device for dedusting dust-laden gases by means of high-performance dust separators designed as swirl chambers, which are connected in parallel to a raw gas duct and are connected to clean gas collecting ducts and dust separating ducts.

Es ist bekannt, daß jede spezielle Aufgabe zur Entstaubung staubbeladener Gase nach dem Fliehkraftprinzip mit umlaufenden Strömungen in starkem Maße vom Durchmesser des Wirbelgehäuses bestimmt wird, so auch bei der Wirbelkammer als Hochleistungsstaubabscheider. Die Durchmesserbegrenzung aus Gründen der erforderlichen Abscheideleistung erzwingt wiederum eine Volumenstrombegrenzung für die einzelnen Wirbelkammern und somit für einen vorgegebenen Gasvolumenstrom die strömungstechnische Aufgabe der gleichmäßigen Volumenstromaufteilung auf eine Vielfachanordnung baugleicher elementarer Entstaubungszellen. Nach der DE- 32 03 498 C2 ist es bekannt, verschiedene Wirbelkammern in Modulen zusammenzufassen, aus denen dann anforderungsspezifische Wirbelkammerabscheideranordnungen zusammengesetzt werden sollen. Die einzelnen Module werden durch Gießen hergestellt, was einen aufwendigen Gußformenbau erfordert. Da die einzelnen Module eine vorbestimmte Anzahl von Wirbelkammern aufweisen, ist ferner eine optimierte Anpassung der Anzahl von Wirbelkammern an das jeweilige Entstaubungsproblem nicht möglich.It is known that each special task for dedusting dust-laden gases according to the centrifugal force principle with circulating currents is largely determined by the diameter of the vortex housing, including in the vortex chamber as a high-performance dust separator. The limitation of the diameter for reasons of the required separation performance in turn forces a volume flow limitation for the individual swirl chambers and thus for a given gas volume flow the fluidic task of evenly dividing the volume flow over a multiple arrangement of identical elementary dedusting cells. According to DE-32 03 498 C2, it is known to combine different vortex chambers in modules, from which requirement-specific vortex chamber separator arrangements are then to be assembled. The individual modules are produced by casting, which requires complex mold construction. Since the individual modules have a predetermined number of vortex chambers, an optimized adaptation of the number of vortex chambers to the respective dedusting problem is also not possible.

Die Aufgabe der Erfindung besteht darin, die Vorrichtung der eingangs genannten Art so zu verbessern, daß mit ein facher und kostengünstiger Fertigung eine Optimierung der Vorrichtung bezogen auf den jeweiligen Einsatzfall möglich ist.The object of the invention is the device to improve the type mentioned at the outset so that the device can be optimized with respect to the respective application with simple and inexpensive production.

Erfindungsgemäß erfolgt die Lösung der Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen der Erfindung werden in den abhängigen Ansprüchen beschrieben.According to the invention, the object is achieved by the characterizing features of claim 1. Advantageous embodiments of the invention are described in the dependent claims.

Nach der Erfindung ist es möglich, durch Modularisierung in einfacher Weise Varianten von Wirbelkammeranordnungen wirtschaftlich herzustellen, die auf den jeweiligen Einsatzbereich optimiert sind. Jede einzelne Wirbelkammer bildet ein Entstaubungsmodul, das kostengünstig als Serienbauteil hergestellt werden kann. Die einzelnen Bauteile einer Wirbelkammer können z.B. durch spanlose Unformung wie Rollprofilieren, Drücken, Tiefziehen, Prägen und dergleichen hergestellt werden. Es ist auch möglich, die einzelnen Bauteile der Wirbelkammern durch Metallgießverfahren herzustellen. Ebenso können die Bauteile für die Wirbelkammern aus Kunststoff hergestellt werden. Für besondere Anwendungsfälle ist es auch möglich, eine Verbundbauweise zur Herstellung von Wirbelkammern vorzusehen, bei der die einzelnen Bauteile der Wirbelkammern aus unterschiedlichen Werkstoffen bestehen und/oder durch unterschiedliche Fertigungsverfahren hergestellt sind.According to the invention, it is possible, by means of modularization, to economically produce variants of swirl chamber arrangements which are optimized for the respective area of use. Each individual swirl chamber forms a dedusting module that can be inexpensively manufactured as a series component. The individual components of a swirl chamber can e.g. produced by non-cutting shaping such as roll profiling, pressing, deep drawing, embossing and the like. It is also possible to manufacture the individual components of the swirl chambers by metal casting processes. The components for the swirl chambers can also be made of plastic. For special applications, it is also possible to provide a composite construction for the production of swirl chambers, in which the individual components of the swirl chambers consist of different materials and / or are produced by different manufacturing processes.

Figur 1 zeigt eine als Entstaubungsmodul 6 ausgebildete Wirbelkammer, die als Blechkonstruktion ausgebildet ist. Die Wirbelkammer 2 weist zwei Tauchrohre 19 auf, die strömungungsausgangsseitig in jeweils einen Diffusor 20 münden. Der Rohgaseintrittsspalt 13 wird durch eine Führungsplatte 27 gebildet, die vom zylindrischen Mantel der Wirbelkammer 2 absteht und eine Durchbrechung in der Zylinderwand der Wirbelkammer 2 überragt.FIG. 1 shows a swirl chamber designed as a dedusting module 6, which is designed as a sheet metal construction. The swirl chamber 2 has two immersion tubes 19, which each open into a diffuser 20 on the flow outlet side. The raw gas inlet gap 13 is formed by a guide plate 27 which protrudes from the cylindrical jacket of the swirl chamber 2 and projects beyond an opening in the cylinder wall of the swirl chamber 2.

Zur Ausbildung einer Vorrichtung 1 zur Entstaubung staubbeladener Gase werden die Wirbelkammern 2 übereinander und nebeneinander in vier gleichen oder weitgehend gleichen tragenden Lochplatten 7, 8, 9, 10 arretiert. Die Lochplatten 7, 8, 9, 10 sind im Abstand von einander angeordnet. In den Durchbrechungen in den Lochplatten 7, 8, 9, 10 sind die Wirbelkammern 2 gasdicht abgedichtet. Die inneren Lochplatten 7, 8 bilden einen Rohgaskanal 3, der im unteren Bereich des Gehäuses der Vorrichtung 1 bis zu einer Beruhigungskammer 12 geführt ist. Über den Rohgaseintritt 11 wird das zu entstaubende staubbeladene Gas in die Beruhigungskammer 12 eingeführt. Zwischen den inneren Lochplatten 7, 8 und den äußeren Lochplatten 9, 10 ist jeweils ein Staubtransportraum 5 ausgebildet, durch den abgeschiedener Staub in einen Staubbunker 16 gelangt. Die seitlichen Begrenzungswände 15 des Staubbunkers 16 sind mit den äußeren Lochplatten 9, 10 verbunden. Außenseitig werden diese von einem Reingassammelkanal 4 umgeben (Fig. 2 und 3).To form a device 1 for dedusting dust-laden gases, the swirl chambers 2 are locked one above the other and next to one another in four identical or largely identical load-bearing perforated plates 7, 8, 9, 10. The perforated plates 7, 8, 9, 10 are arranged at a distance from one another. The swirl chambers 2 are sealed gas-tight in the perforations in the perforated plates 7, 8, 9, 10. The inner perforated plates 7, 8 form a raw gas channel 3, which in the lower region of the housing of the device 1 up to a calming chamber 12 is performed. The dust-laden gas to be dedusted is introduced into the calming chamber 12 via the raw gas inlet 11. A dust transport space 5 is formed between the inner perforated plates 7, 8 and the outer perforated plates 9, 10, through which separated dust reaches a dust bunker 16. The lateral boundary walls 15 of the dust bunker 16 are connected to the outer perforated plates 9, 10. On the outside, they are surrounded by a clean gas collecting duct 4 (FIGS. 2 and 3).

Die Lochplatten 7, 8, 9, 10 werden vorzugsweise auf CNC-gesteuerten Laser-Schneidmaschinen hergestellt. Zur Fertigung können aber auch andere Werkzeugmaschinen verwendet werden. Bei größerer Dimensionierung der Vorrichtung 1 ist es möglich, die Lochplatten 7, 8, 9, 10 in Teilplatten zu unterteilen.The perforated plates 7, 8, 9, 10 are preferably produced on CNC-controlled laser cutting machines. Other machine tools can also be used for production. With larger dimensions of the device 1, it is possible to divide the perforated plates 7, 8, 9, 10 into partial plates.

Die etagenweise und waagerecht nebeneinander vorgesehene Anordnung der Wirbelkammern ermöglicht eine Veringerung des Bauvolumens der Vorrichtung 1. Im Anschluß an die Beruhigungskammer 12 sind keine weiteren Kanäle vorgesehen. Die einzelnen Wirbelkammersäulen 14 werden vielmehr so ausgebildet, daß die Wirbelkammersäulen 14 mit Wirbelkammern 2, deren Rohgaseintrittsspalte 13 einander zugewandt sind, mehrere gleichartige senkrecht orientierte Teilströmungen zwischen den Wirbelkammersäulen 14 ergeben. Dies unterstützt die Vergleichmäßigung der Volumenstromaufteilung auf die Wirbelkammern 2, wobei Teilbereiche der äußeren Wirbelkammerbegrenzungswände mit strömungsführend wirken. Der Fortfall von Strömungsverzweigungskanälen und das Einbeziehen der Wirbelkammerbegrenzungswände zur gleichmäßigen Volumenstromaufteilung führt zur Konstruktionsvereinfachung und zur Verringerung der Herstellungskosten.The arrangement of the swirl chambers on each level and horizontally next to one another enables the construction volume of the device 1 to be reduced. No further channels are provided after the calming chamber 12. The individual vertebral chamber columns 14 are rather designed in such a way that the vertebral chamber columns 14 with swirl chambers 2, the crude gas inlet gaps 13 of which face one another, result in several similar, vertically oriented partial flows between the vertebral chamber columns 14. This supports the equalization of the volume flow distribution on the swirl chambers 2, partial areas of the outer walls of the swirl chamber also acting as flow guides. The elimination of flow branching channels and the inclusion of the vortex chamber boundary walls in order to evenly distribute the volume flow leads to a simplification of the design and a reduction in the production costs.

In Fig. 4 ist eine Vorrichtung 1 dargestellt, bei der die Wirbelkammersäulen 14 winklig zueinander ausgerichtet sind. Jeweils zwei Wibelkammersäulen 14, bei denen die Rohgaseintrittsspalte 13 der Wirbelkammern 2 einander zugewandt sind, sind so ausgerichtet, daß die oberen Wirbelkammern 2 einen geringeren Abstand voneinander haben als die unteren Wirbelkammern 2. Die Vorrichtung 1 kann mittels Profilrahmenträger 17 in einem Rahmen 18 angeordnet werden. Hierdurch können die Staubbunker 16 in einem für das Aushängen von Entsorgungsbehältern für die Entladung ausreichenden Abstand vom Boden angeordnet werden. Es ist möglich, die Vorrichtung 1 dadurch in den Rahmen 16 zu integrieren, daß die vertikalen Lochplatten 7, 8, 9, 10 mit Profilrahmenträgern 17 verbunden werden (Fig. 7).4 shows a device 1 in which the vertebral chamber columns 14 are oriented at an angle to one another. In each case two Wibel chamber columns 14, in which the raw gas inlet gaps 13 of the swirl chambers 2 face each other, are aligned so that the upper swirl chambers 2 have a smaller distance from each other than the lower swirl chambers 2. The device 1 can be arranged in a frame 18 by means of profile frame supports 17 . As a result, the dust bunkers 16 can be arranged at a sufficient distance from the floor for the removal of disposal containers for the discharge. It is possible to integrate the device 1 into the frame 16 in that the vertical perforated plates 7, 8, 9, 10 are connected to profile frame supports 17 (FIG. 7).

Die Diffusoren 20 der Wirbelkammern 2 können in unterschiedlicher Weise mit dem Wirbelkammermantel 22 verbunden werden. So ist es möglich den freien Endabschnitt des Diffusors 10 so abzukanten, daß ein Auflagesteg 23 ausgebildet wird, auf den der Wirbelkammermantel 22 geschoben ist (Fig. 8a). Die Verbindung zwischen Wirbelkammermantel 22 und Diffusor 20 erfolgt hier durch eine Schweißnaht oder Heftschweißung. Es ist aber auch möglich, in dem Wirbelkammermantel 22 eine umlaufende Sicke 24 auszubilden, an der der offene Endabschnitt des Diffusors 20 zur Anlage kommt (Fig. 8 b). Der offene Endabschnitt des Diffusors 20 kann auch als Umlegekante 5 ausgebildet sein, in die der Wirbelkammermantel 22 eingeschoben wird (Fig. 8 c). Es können auch Splinte 26 zur Befestigung des Diffusors 20 an dem Wirbelkammermantel 22 vorgesehen werden. In diesem Fall ist es zweckmäßig, zwischen dem Wirbelkammermantel 22 und dem Diffusor 20 eine Abdichtung 28 aus z.B. einem Silikonstreifen vorzusehen (Fig. 8 d).The diffusers 20 of the swirl chambers 2 can be connected to the swirl chamber jacket 22 in different ways. It is thus possible to bend the free end section of the diffuser 10 in such a way that a support web 23 is formed, onto which the swirl chamber jacket 22 is pushed (FIG. 8a). The connection between the vortex chamber jacket 22 and the diffuser 20 is made here by a weld or tack weld. However, it is also possible to form a circumferential bead 24 in the swirl chamber jacket 22, against which the open end section of the diffuser 20 comes to rest (FIG. 8 b). The open end section of the diffuser 20 can also be designed as a folding edge 5 into which the swirl chamber jacket 22 is inserted (FIG. 8 c). Splint pins 26 can also be provided for fastening the diffuser 20 to the swirl chamber jacket 22. In this case, it is expedient to provide a seal 28 made of, e.g., between the vortex chamber jacket 22 and the diffuser 20. to provide a silicone strip (Fig. 8 d).
