Description

Leitflächeneinbau in gekrümmten oder winklig gebogenen Gaskanälen, insbesondere in der Zuleitung zu Elektrofiltern In gekrümmten oder winklig gebogenen Gaskanälen, insbesondere in der Zuleitung zu Elektrofiltern eingebaute Leitflächen, die aus mehreren der Krümmung oder Biegung des Gaskanals angepaßten, parallel oder konzentrisch zueinander verlaufenden Blechen bestehen, sind bekannt. Wenn nun das Gas, das zwischen diesen Leitflächen hindurchströmt, Staub oder sonstige Schwebeteilchen enthält, wie dies z. B. beim Betriebe von Elektrofiltern der Fall ist, so kommt es an den Stellen, an denen die Bleche quer zur Senkrechten, d. h. mehr oder weniger waagerecht übereinanderliegen, zu Staubansammlungen und damit zu Verstopfungen des Gaskanals, die den gesamten Betrieb gefährden. In Erkenntnis dieses Mangels wird der Erfindung gemäß die Einrichtung so getroffen, daß solche Staubablagerungen zwischen den Leitblechen unmöglich werden. Zu diesem Zweck sind die Bleche, an der Umlenkstelle beginnend, in ihren quer zur Senkrechten verlaufenden, übereinanderliegenden Teilen mit Durchbrechungen versehen, so daß der Staub durch die Durchbrechungen hindurchfallen kann und die Gasgassen zwischen den übereinanderliegenden Blechen in ausreichendem Maße staubfrei bleiben.Guide surface installation in curved or angled gas ducts, especially in the feed line to electrostatic precipitators In curved or angled Gas ducts, especially guide surfaces built into the supply line to electrostatic precipitators, those adapted from several of the curvature or bend of the gas channel, parallel or There are concentric metal sheets are known. If now that Gas that flows between these guide surfaces, dust or other suspended particles contains, as z. B. is the case when operating electrostatic precipitators, so comes it at the points where the sheets are perpendicular to the vertical, d. H. more or less lie horizontally on top of each other, to dust accumulation and thus to blockages of the Gas ducts that endanger the entire operation. Recognizing this shortcoming will the invention according to the device taken so that such dust deposits between the baffles become impossible. For this purpose, the metal sheets are at the deflection point beginning, in their transverse to the vertical, superimposed parts provided with perforations so that the dust can fall through the perforations can and the gas paths between the stacked sheets in sufficient Dimensions remain dust-free.

Im Gegensatz zu einer bekannten Ausführungsform, bei der in dem gekrümmten Gaskanal ein quer zur Gasströmung gerichtetes durchbrochenes Blech angeordnet ist, das den Zweck hat, die Gasströmung örtlich verschieden abzudrosseln und in strömungstechnisch richtige Bahnen zu lenken, wird mit den Durchbrechungen in den Leitblechen nach der Erfindung eine Drosselung des Gases durch t»erschnittsverengutig nicht bezweckt; im Gegenteil soll gerade durch die Abführung des anfallenden Staubes durch die Durchlirechungen hindurch eine Drosselung, die bei einer Staubablagerung in den Gasgassen unweigerlich eintreten würde, grundsätzlich vermieden werden.In contrast to a known embodiment in which in the curved A perforated plate directed transversely to the gas flow is arranged in the gas duct, the purpose of which is to throttle the gas flow locally differently and in terms of flow right one To direct tracks, is with the openings in the guide plates according to the invention a throttling of the gas by means of the cut narrowing is not intended; on the contrary is supposed to be due to the removal of the dust through the perforations through a throttling, which inevitably occurs in the event of dust deposits in the gas lanes would occur, should be avoided in principle.

Eine Durchbrechung der Leitflächen im Sinne der Erfindung tritt auch dann ein, wenn man die einzelnen Blechbahnen in an sich bekannter Weise aus Durchlaßschlitze bildenden Streifen gestaffelt anordnet, jedoch derart, daß die auf der oberen Seite dereinzelnen Streifen von den Durchlal.iSChlltzen gebildeten Qffnungen der Gasströniungsrichtung abgekehrt sind.A breakthrough in the guide surfaces within the meaning of the invention also occurs then one, if one of the individual sheet metal tracks in a known manner from passage slots forming strips arranged in a staggered manner, but in such a way that the one on the upper side the individual strips of openings in the direction of gas flow formed by the passages have turned away.

Auf der Zeichnung ist an zwei Beispielen veranschaulicht, wie die Erfindung ausgeführt «-erden kann.The drawing shows two examples of how the Invention can be carried out.

ach Abb. i sind in der L; mlenkstelle des gekrümmten Gaskanals i, 2, der zu dem Elektrofilter ; führt, die Leitflächen 4 einbebaut, die in entsprechender Krümmung sowohl in den senkrechten Kanalteil i wie in den nach dem Elektrofilter führenden waagerechten Kanalteile hineinreichen. Die Leitflächen .1 sind, an der Umlenkstelle ins Waagerechte beginnend, in ihren quer zur Senkrechten verlaufenden, übereinanderliegenden Teilen mit Durchbrechungen 5 versehen. Unterhalb der Durchbrechungen 5 der Leitflächen wird der Gaskanal 2 vorteilhaft um einen Staubsammelraum 6 erweitert.ach fig. i are in the L; m steering point of the curved gas channel i, 2, the one to the electrostatic precipitator; leads, built in the guide surfaces 4, the corresponding Curvature both in the vertical duct part i and in the one after the electrostatic precipitator reaching into the leading horizontal duct parts. The guide surfaces .1 are on the The deflection point starting in the horizontal, in its transverse to the vertical, Provided parts lying one above the other with openings 5. Below the breakthroughs 5 of the guide surfaces, the gas duct 2 is advantageously expanded by a dust collecting space 6.

Nach Abb.2 handelt es sich um einen gekrümmten Gaskanal i, 2, durch den aber das Gas das Elektrofilter 3 nicht wie in Abb. i in waagerechter, sondern in senkrechter Richtung von unten nach oben durchströmt. An der Knickstelle des Gaskanals i, 2 befinden sich aus einzelnen Streifen ; bestehende, der Krümmung des Gaskanals angepaßte Leitflächen. Die Streifen 7 sind aus der Umlenkkurve in Richtung der Gasströmung derart nach einwärts gedreht, daß sich eine gestaffelte Anordnung mit der Gasströmung abgekehrten Staubdurchlaßschlitzen 8 ergibt. Auch hier befindet sich zweckmäßig unterhalb der Staubdurchlässe der Leitflächen ein Staubsammelraum 6.According to Fig.2 it is a curved gas channel i, 2, through However, the gas does not move the electrostatic precipitator 3 horizontally, as in Fig. i, but flows through in a vertical direction from bottom to top. At the kink of the Gas ducts i, 2 are made up of individual strips; existing, the curvature of the Guide surfaces adapted to the gas duct. The strips 7 are out of the deflection curve in the direction the gas flow is rotated inward so that there is a staggered arrangement with the gas flow turned away dust passage slots 8 results. Also located here A dust collection space is expediently located below the dust passages of the guide surfaces 6th

Bei der betriebsmäßigen Ausführung der Bauart nach Abb.2 beträgt die Breite der Gasgassen z. B. 500 mm, während die einzelnen gestaffelt angeordneten Streifen 7 nur um einen Bruchteil von dieser Gasgassenbreite, d. 1i. um etwa 2o bis 30 mm weit, in den Gasweg hineingedreht zu werden brauchen, um die Staubauslaßschlitze 8 im Sinne der Erfindung zu schaffen. Durch dieses geringe Vorspringen der Streifen 7 in den Gasweg wird also eine praktisch zur Geltung kommende Querschnittsverengung der Gasgassen und damit eine Drosselung der Gasströmung nicht hervorgerufen.In the operational version of the design according to Fig. 2, the width of the gas lanes is z. B. 500 mm, while the individual staggered strips 7 by only a fraction of this gas lane width, d. 1i. need to be turned into the gas path by about 20 to 30 mm in order to create the dust outlet slots 8 within the meaning of the invention. As a result of this slight protrusion of the strips 7 into the gas path, a cross-sectional constriction of the gas passages, which is practically effective, and thus a throttling of the gas flow is not brought about.
