Description
Umschaltorgan, insbesondere zur Änderung der Strömungsrichtung bei Gasverbrennungsanlagen Zur Durchführung von Umschaltvorgängen, z. B. bei Gasverbrennungsanlagen mit Gasen hoher Temperaturen, großen Staubgehalten und von aggressivem Charakter, ist mit den bekannten Wendeklappen nicht immer eine sichere Abdichtung zu erreichen. In diesen Fällen gibt der Wasserverschluß die Möglichkeit eines gasdichten Verschließens.Switching element, in particular to change the direction of flow Gas incinerators To carry out switching processes, e.g. B. in gas incinerators with gases of high temperatures, high dust contents and of an aggressive character, it is not always possible to achieve a reliable seal with the known reversible flaps. In these cases, the water seal gives the possibility of a gas-tight seal.
Bei großen Gasmengen und hohen Drücken ergibt sich bei der Betätigung des Wasserverschlusses jedoch ein sehr großer Wasserverlust, da das Wasser von den mit großen Geschwindigkeiten durch die Wasserverschlüsse strömenden Gasen mitgerissen wird.In the case of large amounts of gas and high pressures, the operation results of the water seal, however, a very large water loss, since the water from the entrained gases flowing through the water closures at high speeds will.
Durchdie Erfindung wird d.ieser Nachteil in einfacher und sicherer Weise dadurch vermieden, daß das Umschaltorgan bei abgesperrtem Durchlaß einen begrenzten Gasdurchtritt zuläßt, und daß für den völligen Abschluß ein Wasserverschluß nachgeschaltet ist, der erst nach dem Umschalten des Umschaltorgans geflutet wird.The invention makes this disadvantage easier and safer Way avoided by the fact that the switching element has a limited when the passage is blocked Permits gas passage, and that a water seal is connected downstream for complete closure which is only flooded after switching over the switching element.
Weitere Merkmale des Erfindungsgegenstandes ergeben sich aus der Beschreibung -der Ausführungsbeispiele.Other features of the subject invention will be apparent from the description - of the embodiments.
In der Zeichnung ist der Erfindungsgegenstand in mehreren beispielsweisen Ausführungsformen dargestellt, und zwar veranschaulicht Fig. 1 den senkrechten Schnitt durch die Anlage der Drosselvorrichtung mittels eines vor dem Wasserverschluß vorgesehenen drehbaren Wendeklappenverschlusses, Fig. 2 den senkrechten Schnitt durch eine Anlage, bei der ein die zentrale Gaszuleitung aufweisender Drehschieber angeordnet ist, Fig. 3 den Querschnitt durch den Drehschieber, Fig. 4 den senkrechten Schnitt durch eine Anlage mit Anordnung einer gewichtsbelasteten Klappe, Fig. 5 den senkrechten Schnitt durch eine Anlage, bei der die Drosselvorrichtung aus einer zweiflügeligen Klappe besteht.In the drawing, the subject matter of the invention is shown in several exemplary embodiments, namely Fig. 1 illustrates the vertical section through the system of the throttle device by means of a rotatable reversible flap lock provided in front of the water seal Gas supply line having rotary valve is arranged, Fig. 3 the cross section through the rotary valve, Fig. 4 the vertical section through a system with an arrangement of a weight-loaded flap, Fig. 5 the vertical section through a system in which the throttle device consists of a two-leaf flap.
Bei der Anordnung der Drosselvorrichtung nach Fig. 1 mündet der Gaseintritt 1 auf eine mit zwei Leitblechen 2 versehene, den Gasdurchtritt frei lassende Trommel 3, wobei in der dargestellten Schaltstellung das Gas mit dem Kanal 4 zur Anlage verbunden und der zu dem vorgesehenen Wasserverschluß 5 führende Kanal 6 durch die Drosseleinrichtung abgedeckt ist, so daß Staub nur in geringem Maße in den Wasserverschluß gelangen kann.In the arrangement of the throttle device according to Fig. 1, the gas inlet 1 opens to a provided with two guide plates 2, the passage of gas leaving free drum 3, wherein the gas with the channel 4 is connected in the illustrated switch position to the plant and the leading to the intended water seal 5 Channel 6 is covered by the throttle device, so that dust can only get into the water seal to a small extent.
Bei geänderter Schaltstellung gelangt das Gas durch den Wasserabschluß in die freie Rohrleitung 7. Bei der Anlage gemäß Fig. 2 und 3 ist ein drehbarer, nach einer Seite offener Drehschieber 8 angeordnet, durch dessen Drehung der jeweilige Gasweg nach dem Kanal 4 bzw. 7 freigegeben wird.In modified switching position, the gas passes through the water close to the free pipe 7. In the system of FIG. 2 and 3, a rotatable, open to one side rotary valve 8 is arranged, through the rotation of the respective gas path after the channel 4 or 7 is released will.
Wie aus Fig. 4 ersichtlich, ist hierbei vor dem Wasserverschluß 5 eine einflügelige Klappe 9 vorgesehen, die durch ein nach außen führendes Gegengewicht 10 ausgeglichen ist. Das Anwendungsgebiet dieser Klappe ist auf eine geringe Druckdifferenz zwischen den Räumen vor und hinter dem Verschluß beschränkt, da sonst große Kräfte auf die Wendeklappe wirken. Diese Klappe kann auch, wie aus Fig. 5 zu ersehen, als zweiflügelige Klappe 11 ausgebildet sein.As can be seen from FIG. 4, a single-wing flap 9 is provided in front of the water seal 5 , which is balanced by a counterweight 10 leading to the outside. The field of application of this flap is limited to a small pressure difference between the spaces in front of and behind the closure, since otherwise large forces act on the reversible flap. As can be seen from FIG. 5, this flap can also be designed as a two-wing flap 11 .
Die dargestellten dreh- oder schwenkbaren Verschlüsse haben konstruktiv gesehen mancherlei Vorteile im Vergleich zu Mehrwegeventilen, aber sie schließen nicht so dicht. Wenn der völlige Abschluß durch einen nachgeschalteten Wasserverschluß bewirkt wird, lassen sie sich aber gut verwenden.The rotatable or pivotable closures shown have a structural design seen some advantages compared to multi-way valves, but they close not so tight. If the complete closure by a downstream water seal but they can be used well.
