Description
Gegenstand der Erfindung ist eine flüssigkeitsbetriebene Mehrlochdruckdüse, die als Topf mit gelochtem Boden ausgebildet und in den Krümmer einzubauen ist, der bei Verkokungsöfen das Steigrohr und die Vorlage verbindet.The invention relates to a liquid-operated multi-hole pressure nozzle, which is designed as a pot with a perforated base and is to be installed in the elbow, which connects the riser pipe and the template in coking ovens.
Durch den Krümmer, mittels dessen jede einzelne Ofenkammer an die Vorlage angeschlossen ist, wird nicht nur während des Betriebes der Ofen ammoniakhaltige Flüssigkeit eingeführt, die unter einem Druck von einigen bar steht, vielmehr benutzt man auch eine in den Krümmer eingebaute Düse dazu, während des Füllens der Öfen die sich dabei entwickelnden Gase durch den oberen Gassammelraum und das Steigrohr unter Anwendung sehr hohen Druckes mittels einer Düse in die Vorlage abzusaugen.Through the elbow, by means of which each individual oven chamber is connected to the template, not only is the oven introduced ammonia-containing liquid during operation, which is under a pressure of a few bar, but you also use a nozzle built into the elbow during the Filling the furnaces to evacuate the resulting gases through the upper gas collecting space and the riser pipe using a nozzle at very high pressure.
Die Erfinder haben sich die Aufgabe gestellt, durch die Gestaltung einer in der Fertigung sehr einfachen Düse und den Einbau einer solchen Düse im Krümmer eine Anordnung zu schaffen, die sich dadurch auszeichnet, dass bei Anwendung bestimmter höher Drücke und bestimmter, in der Zeiteinheit aufgegebener, als Treibmittel dienender Flüssigkeitsmengen maximale Gasmengen abgesaugt werden.The inventors have set themselves the task of creating an arrangement by designing a nozzle that is very simple to manufacture and installing such a nozzle in the manifold, which is characterized in that when using certain higher pressures and certain, maximum gas quantities are sucked off as the propellant of liquid quantities.
Aufgrund eingehender Versuche wurde gemäss der Erfindung eine optimale Gestaltung einer solchen Mehrlochdruckdüse erzielt, wenn die Bohrungen der Düse in bestimmter Weise kegelstumpfförmig in Richtung des Flüssigkeitsdurchganges erweitert sind und das von der Düse erzeugte Strahlenbündel den Querschnitt des Krümmers erst an dessen Übergang in die Vorlage lückenlos ausfüllt.Based on extensive tests, an optimal design of such a multi-hole pressure nozzle was achieved according to the invention if the bores of the nozzle are expanded in a truncated cone in the direction of the liquid passage and the beam of rays generated by the nozzle fills the cross-section of the elbow without gaps only at its transition into the template .
Im Gegensatz zu zylindrischen Bohrungen, bei denen die austretenden Flüssigkeitsstrahlen erhalten bleiben, tritt bei der erfindungsgemässen kegelstumpfförmigen Gestaltung der Bohrungen eine Auflösung der Flüssigkeitsstrahlen nach dem Austritt aus der Düse ein, durch eine besonders hohe Gasmenge von der Flüssigkeit mitgerissen wird. Das Strahlenbündel, das die Düse erzeugt, soll sich derart erweitern, dass es erst am unteren Ende des Krümmers bei seinem Eintritt in die Vorlage den vollen Querschnitt ausfüllt.In contrast to cylindrical bores, in which the emerging liquid jets are retained, in the inventive truncated cone-shaped design of the bores, the liquid jets dissolve after exiting the nozzle and are entrained by the liquid due to a particularly large amount of gas. The beam of rays that the nozzle generates should expand in such a way that it only fills the full cross-section at the lower end of the elbow when it enters the template.

- 2a and 2b are vertical sections through the axes of two nozzles with different thicknesses of the base and therefore also different lengths of the bores penetrating them,

In Figur 1 ist mit 10 das Steigrohr, mit 11 die Vorlage bezeichnet, mit 12 der Krümmer. In dessen oberer Wandung ist die Mehrlochdruckdüse 13 eingesetzt. Mit 14 ist der Flüssigkeitskegel bezeichnet, der durch die aufgegebene Flüssigkeit erzeugt wird. de ist der Lochdurchmesser der Bohrungen an der Wassereintrittsseite, dA der Lochdurchmesser der Bohrungen an der Wasseraustrittsseite.In FIG. 1, the riser pipe is designated 10, the
Mit d, ist der Durchmesser des Umfangkreises der Bohrungen auf der Wassereintrittsseite, d.h. des Kreises, der von aussen die von den Eintrittsöffnungen mit dem Durchmesser dE gebildeten Kreise tangiert. Mit d2 ist der Durchmesser des Umfangkreises auf der Wasseraustrittsseite bezeichnet, d.h. des Kreises, der die mit dem Durchmesser dA bezeichneten Kreise von aussen tangiert, die die Austrittsöffnungen der Bohrungen bilden.With d is the diameter of the circumferential circle of the bores on the water inlet side, ie the circle which from outside affects the circles formed by the inlet openings with the diameter d E. The diameter of the circumferential circle on the water outlet side is denoted by d 2 , ie the circle which, from the outside, affects the circles denoted by the diameter d A , which form the outlet openings of the bores.
Mit δ ist der Kegelöffnungswinkel bezeichnet, der das Mass der kegelstumpfförmigen Erweiterung der Bohrungen bildet.Δ denotes the cone opening angle, which forms the measure of the frustoconical widening of the bores.
Durch eingehende Versuche wurden die folgenden optimalen Werte der genannten Grössen ermittelt, die bei Anwendung eines bestimmten Druckes für die Zuführung der Flüssigkeit zur Düse zu maximalen Werten des von der Düse abgesaugten, d.h. vom Steigrohr in die Vorlage beförderten Gases führen.The following optimal values of the quantities mentioned were determined by in-depth tests. lead from the riser pipe into the gas transported.
Es soll nämlich das Quadrat des Verhältnisses des Lochdurchmessers de der Bohrung an der Wassereintrittsstelle zum Lochdurchmesser dA der Bohrung an der Wasseraustrittsstelle (dE dA)2 einen Wert zwischen 0,4 und 0,85, vorzugsweise zwischen 0,65 und 0,7 haben.Namely, the square of the ratio of the hole diameter d e of the hole at the water entry point to the hole diameter d A of the hole at the water exit point (d E d A ) 2 should have a value between 0.4 and 0.85, preferably between 0.65 and 0 , 7 have.
Das genannte Verhältnis ist offenbar ein Mass für die Erweiterung der Bohrung. Die Erweiterung kann, je nach der Länge der Bohrung, d.h. nach der Dicke des Bodens der Düse, schneller oder langsamer erfolgen. Das Mass hierfür bildet der öffnungswinkel des Kegels, aus dem die Bohrungserweiterung herausgeschnitten ist. Für diesen Kegelöffnungswinkel liegt der optimale Wert zwischen 2° und 10°, vorzugsweise zwischen 3° und 7°.The ratio mentioned is obviously a measure of the expansion of the bore. Depending on the length of the bore, i.e. according to the thickness of the bottom of the nozzle, faster or slower. The measure of this is the opening angle of the cone from which the bore extension is cut out. The optimum value for this cone opening angle is between 2 ° and 10 °, preferably between 3 ° and 7 °.
Bei Anordnung der Bohrungen auf einem Kreis soll das Verhältnis des Durchmessers d, des Umfangkreises der Bohrungen auf der Eintrittsseite zu dem Durchmesser d2 des Umfangkreises auf der Austrittsseite, also der Wert d1 d2 zwischen 0,5 und 0,95, vorzugsweise zwischen 0,8 und 0,9 liegen.If the bores are arranged on a circle, the ratio of the diameter d, the circumferential circle of the bores on the inlet side to the diameter d 2 of the circumferential circle on the outlet side, that is to say the value d 1 d 2, should be between 0.5 and 0.95, preferably between 0.8 and 0.9 are.
Um sich unterschiedlichen Druckverhältnissen oder anderen aus dem Betrieb sich ergebenden Bedingungen anpassen zu können, soll die Mehrlochdruckdüse leicht höhenverstellbar innerhalb des Krümmers angeordnet sein.To different pressure conditions or other resulting from the operation To be able to adapt to conditions, the multi-hole pressure nozzle should be arranged within the elbow to be easily adjustable in height.
Neben einer mittleren Bohrung oder einer Gruppe von drei oder vier Bohrungen nahe der Mitte können die Bohrungen in einem oder mehreren äusseren Kreisen angeordnet sein. Die Zahl der Bohrungen wird bestimmt durch die Menge der zu versprühenden Flüssigkeit, den anzuwendenden Druck und andere Betriebsgrössen.In addition to a central hole or a group of three or four holes near the center, the holes can be arranged in one or more outer circles. The number of holes is determined by the amount of liquid to be sprayed, the pressure to be applied and other operating sizes.
Innerhalb jedes Kreises von Bohrungen soll zur Erzielung optimaler Ausnutzung des verwendeten Düsenkörpers der Abstand der den Kreis bildenden Bohrungen voneinander einen optimalen Wert im Verhältnis zum Durchmesser der Bohrungen haben. Als Regel wurde ermittelt, dass innerhalb der Lochkreise der Mittenabstand a, benachbarter Bohrlöcher mit dem Durchmesser dA auf der Flüssigkeitsaustrittsseite zu dem Durchmesser dA in einem Verhältnis steht, dessen Wert zwischen 1,8 und 2,8, vorzugsweise bei 2,4 liegt.Within each circle of bores, the distance between the bores forming the circle from one another should have an optimal value in relation to the diameter of the bores in order to achieve optimum utilization of the nozzle body used. As a rule, it was determined that the center distance a, adjacent boreholes with the diameter d A on the liquid outlet side and the diameter d A are in a ratio in the hole circles, the value of which is between 1.8 and 2.8, preferably 2.4 .
Werden mehrere Lochkreise benutzt, wie dies bei den in Figur 3 dargestellten Düsen der Fall ist, so soll der Radialabstand a2 der durch die Mitten der Bohrlöcher eines Lochkranzes gehenden Kreise in einem bestimmten Verhältnis zu dem Durchmesser dA auf der Flüssigkeitsaustrittsseite stehen, und zwar soll das Verhältnis a2 dA einen Wert haben, der zwischen 1,5 und 2,6, vorzugsweise bei 2,1 liegt.If several circles of holes are used, as is the case with the nozzles shown in FIG. 3, the radial distance a 2 of the circles passing through the center of the drilled holes of a ring of holes should be in a certain ratio to the diameter d A on the liquid outlet side, specifically the ratio a 2 d A should have a value which is between 1.5 and 2.6, preferably 2.1.
Durch die Innehaltung der vorstehend genannten Werte für die Masse und die Anordnung der Bohrungen in der Mehrlochdruckdüse lassen sich maximale Werte für die bei stimmten Drücken und bestimmten Werten der in der Zeiteinheit zugeführten Flüssigkeitsmengen für die in der Zeiteinheit abgesaugten Gasmengen, insbesondere auch bei der Füllgasabsaugung, erzielen.By observing the above-mentioned values for the mass and the arrangement of the bores in the multi-hole pressure nozzle, maximum values for the liquid quantities supplied in the time unit for certain pressures and specific values for the gas quantities sucked out in the time unit, in particular also for the filling gas suction, can be obtained. achieve.
