Abstract

For charging and atomising at least two different fluids in a spray absorber, a rotating atomiser disc (1) is proposed which is of three-part construction, specifically having an outer, plate-shaped rotating body (6) with a first group of radially outwardly directed atomiser nozzles (5), a central, annular rotating body (7) with a second group of radially outwardly directed atomiser nozzles (4) and a third, annular rotating body (8), the three rotating bodies (6, 7, 8) being arranged concentrically with respect to one another and being connected to one another at their edges to form two annular inlet openings (10, 11) which are concentric to one another and two separate receptacle spaces (2, 3). Using this rotating atomiser disc (1), two fluids which contain different materials which react quickly with one another can be atomised simultaneously, without firmly adhering caking being formed. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Rotations-Zerstäuberscheibe zum Einbringen und Zerstäuben von mindestens zwei unterschiedlichen Flüssigkeiten in einen Sprühabsorber.The invention relates to a rotary atomizer disc for introducing and atomizing at least two different liquids into a spray absorber.

Derartige Rotations-Zerstäuberscheiben werden verwendet, um Flüssigkeiten, die andere Stoffe gelöst oder als Aufschlämmung enthalten, in einen heißen Gasstrom zu versprühen, wobei die Flüssigkeit verdampft und die anderen Stoffe als feines Pulver anfallen, das als Produkt anschließend vom Gasstrom abgetrennt wird. Man hat diese Technik seit einiger Zeit auch schon zum Einbringen eines Absorbens bei der Abgasreinigung angewandt, insbesondere zum Versprühen einer Kalk-Aufschlämmung in einen S02-haltigen Abgasstrom, wobei das S02 an Ca gebunden und schließlich ein CaS03 - und CaS04-haltiges Pulverprodukt erhalten wird.Rotary atomizing disks of this type are used to spray liquids which contain other substances or as a slurry into a hot gas stream, the liquid evaporating and the other substances being obtained as fine powder, which is then separated as a product from the gas stream. This technique has also been used for some time to introduce an absorbent in exhaust gas purification, in particular for spraying a lime slurry into an exhaust gas stream containing S0 2 , the S0 2 being bound to Ca and finally a CaS0 3 - and CaS0 4 - containing powder product is obtained.

Moderne Abgasreinigungsverfahren arbeiten vielfach mehrstufig, weil nur so die geforderten Reingaswerte erreicht werden können. Dabei werden der quasi-trockenen Absorptionsstufe häufig ein oder mehrere naß arbeitende Wäscherstufen nachgeschaltet, von deren Umlaufflüssigkeit stets ein gewisser Teil ausgeschleust und durch frische Waschflüssigkeit ersetzt werden muß. Dieses sogenannte Abstoßwasser enthält die in der Wäscherstufe aus dem Abgas abgetrennten Schadstoffe und muß daher einer gesonderten Aufbereitung zugeführt werden, was sehr aufwendig ist. Man hat daher auch schon vorgeschlagen, das Abstoßwasser in dem vorhandenen Sprühabsorber mitzuverdampfen, so daß die Schadstoffe zusammen mit dem CaS03 - und CaS04-haltigen Pulverprodukt anfallen. D.h., auch bei mehrstufiger Abgasreinigung fällt nur ein einziges Restprodukt an und man kann sich die Waschwasseraufbereitung vollständig sparen.Modern exhaust gas cleaning processes often work in several stages because this is the only way to achieve the required clean gas values. In this case, the quasi-dry absorption stage is often followed by one or more wet-working laundry stages, of which a certain part of the circulating liquid must always be discharged and replaced by fresh washing liquid. This so-called rejection water contains the pollutants separated from the exhaust gas in the scrubber stage and must therefore be sent to a separate treatment, which is very expensive. It has therefore also been proposed to co-evaporate the rejection water in the existing spray absorber, so that the pollutants are obtained together with the powder product containing CaS0 3 and CaS0 4 . This means that even with multi-stage exhaust gas purification, only a single residual product is created and the washing water treatment can be completely saved.

Es hat sich jedoch herausgestellt, daß das Abstoßwasser nicht mit der sogenannten Kalkmilch (d.h. der Aufschlämmung von Calciumhydroxid in Wasser) über die gleiche Rotations-Zerstäuberscheibe in den Gasstrom eingebracht werden kann, weil das saure Abstoßwasser sofort mit der basischen Kalkmilch reagiert, wobei unlösliche, anbakkende Verbindungen ausfallen, so daß die Rotations-Zerstäuberscheiben in kürzester Zeit völlig verstopft sind und ausgewechselt werden müssen. Selbst mit einem Rotations-Zerstäuber gemäß DE-OS 37 32 353, bei dem zwei oder mehrere nicht mitdrehende Einrichtungen für das getrennte Einspeisen mehrerer unterschiedlicher Flüssigkeiten in den Aufnahmeteil der Zerstäuberscheibe vorgesehen sind, ließ sich das Problem nicht lösen.However, it has been found that the rejection water cannot be introduced into the gas stream with the so-called lime milk (ie the slurry of calcium hydroxide in water) via the same rotary atomizing disc, because the acidic rejection water immediately reacts with the basic lime milk, whereby insoluble, hooking connections fail, so that the rotary atomizer disks are completely clogged in a very short time and have to be replaced. Even with a rotary atomizer according to DE-OS 37 32 353, in which two or more non-rotating devices are provided for the separate feeding of several different liquids into the receiving part of the atomizer disc, the problem could not be solved.

Weiterhin sind als Lackiereinrichtungen gestaltete Zerstäuberscheiben bekannt, denen allen gemeinsam ist, daß damit flüssige oder pulverförmige Überzugsmaterialien in einem elektrostatischen Feld versprüht werden. Aus der DE-OS 16 52 390 und der DE-OS 15 77 920 sind zwar Zerstäuberscheiben bekannt, die es ermöglichen, verschiedene, auch miteinander reaktive Lackbestandteile gleichzeitig zu versprühen, aber die vorgesehenen lonisationskanten, die Kristallisationszentren darstellen und Anbackungen fördern, lassen diese Zerstäuberscheiben für einen Einsatz in Sprühadsorbern als ungeeignet erscheinen.Furthermore, atomizing disks designed as coating devices are known, which all have in common that liquid or powder coating materials are sprayed with them in an electrostatic field. From DE-OS 16 52 390 and DE-OS 15 77 920 atomizer disks are known which make it possible to spray different lacquer components, which are also reactive with one another, but the ionization edges provided, which represent crystallization centers and promote caking, allow these atomizer disks appear to be unsuitable for use in spray adsorbers.

Es besteht somit die Aufgabe, für das Einbringen und Zerstäuben von mindestens zwei unterschiedlichen Flüssigkeiten in einen Sprühabsorber eine Rotations-Zerstäuberscheibe vorzuschlagen, die auch dann noch über normale Betriebszeiten funktionsfähig bleibt und nicht verstopft, wenn die Flüssigkeiten rasch miteinander reagierende Stoffe enthalten, die fest anhaftende Anbackungen bilden.There is therefore the task of proposing a rotary atomizer disc for introducing and atomizing at least two different liquids into a spray absorber, which remains functional even during normal operating times and does not become blocked if the liquids contain rapidly reacting substances that adhere firmly Form caking.

Zur Lösung dieser Aufgabe wird vorgeschlagen, die Rotations-Zerstäuberscheibe so auszubilden, daß sie dreiteilig ausgebildet ist, und zwar mit einem äußeren, tellerförmigen Rotationskörper mit einer ersten Gruppe von radial nach außen gerichteten Zerstäuber-Düsen, einem mittleren, ringförmigen Rotationskörper mit einer zweiten Gruppe von radial nach außen gerichteten Zerstäuber-Düsen sowie einem dritten, ringförmigen Rotationskörper, wobei die drei Rotationskörper konzentrisch zueinander angeordnet und unter Ausbildung zweier ringförmiger, zueinander konzentrischer Eintrittsöffnungen und zweier getrennter Aufnahmeräume randseitig miteinander verbunden sind.To solve this problem, it is proposed to design the rotary atomizer disc in such a way that it is constructed in three parts, namely with an outer, plate-shaped rotary body with a first group of radially outwardly directed atomizer nozzles, a central, annular rotary body with a second group of radially outwardly directed atomizer nozzles and a third, ring-shaped rotating body, the three rotating bodies being arranged concentrically to one another and being connected to one another at the edges to form two annular, mutually concentric inlet openings and two separate receiving spaces.

Zweckmäßig ist es ferner, wenn die drei Rotationskörper den gleichen Außendurchmesser aufweisen und die äußeren Enden der Austrittsöffnungen der ersten und zweiten Gruppe von Zerstäuber-Düsen im gleichen Abstand von der Rotationsachse enden. In Weiterbildung des Erfindungsgedankens ist ferner vorgesehen, daß der äußere tellerförmige Rotationskörper zur Befestigung der Rotations-Zerstäuberscheibe an/auf der Welle eines Drehantriebs eine zentrale Bohrung aufweist.It is also expedient if the three rotating bodies have the same outer diameter and the outer ends of the outlet openings of the first and second group of atomizer nozzles end at the same distance from the axis of rotation. In a further development of the inventive concept, it is further provided that the outer plate-shaped rotary body for fastening the rotary atomizer disc on / on the shaft of a rotary drive has a central bore.

In Fig. 1 ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt. Die Rotations-Zerstäuberscheibe (1) besteht aus drei unterschiedlichen, konzentrisch angeordneten Rotationskörpern (6, 7, 8), die randseitig miteinander verbunden sind und zwischen sich zwei getrennte Aufnahmeräume (2, 3) bilden, die über ringförmige Eintrittsöffnungen (10, 11) aus einer nicht mitdrehenden und nicht dargestellten Einrichtung mit unterschiedlichen Flüssigkeiten versorgt werden. Der äußere, tellerförmige Rotationskörper (6) besitzt eine erste radial nach außen gerichtete Gruppe von Zerstäuber-Düsen (5). Der mittlere ringförmige Rotationskörper (7) weist eine entsprechende Gruppe von Zerstäuber-Düsen (4) auf. Die einzelnen Gruppen von Zerstäuberdüsen (4, 5) können eine unterschiedliche oder eine gleiche Anzahl von Düsen aufweisen. Der äußere, tellerförmige Rotationskörper (6) ist außerdem mit einer Bohrung (9) versehen, die zur Befestigung der Rotations-Zerstäuberscheibe (1) an bzw. auf der Welle eines Drehantriebs dient.In Fig. 1 an embodiment of the inventive concept is shown. The rotary atomizer disc (1) consists of three different, concentrically arranged rotating bodies (6, 7, 8), which are connected to one another at the edges and form two separate receiving spaces (2, 3) between them, which are formed by annular inlet openings (10, 11) are supplied with different liquids from a device that does not rotate and is not shown. The outer, plate-shaped rotary body (6) has a first radially outward group of atomizer nozzles (5). The central annular rotary body (7) has a corresponding group of atomizer nozzles (4). The individual groups of atomizing nozzles (4, 5) can be one under have different or an equal number of nozzles. The outer, plate-shaped rotary body (6) is also provided with a bore (9) which is used to fasten the rotary atomizer disc (1) to or on the shaft of a rotary drive.
