Definitions

  • the invention relates to a multi-hole pressure nozzle built into the riser tube and the template on coking ovens, designed as a pot with a perforated bottom, with truncated cone-shaped bores for blowing in a compressible propellant, preferably steam.
  • An ammonia-containing aqueous solution is injected into the tube which connects the riser tube to the receiver in the chambers of coking ovens while the distillation gas is being drawn off.
  • steam is often blown into this tube in order to draw off the filling gases into the receiver.
  • a nozzle is used, which can be designed as a pot with a perforated base.
  • the inventors have set themselves the task of designing a multi-hole pressure nozzle that is simple to manufacture and arranging it in the tube that connects the riser tube and the template at a given pressure of the compressible propellant, usually steam, by means of certain amounts of propellant supplied in the unit of time to reach a maximum amount of aspirated filling gases.
  • the multi-hole pressure nozzle has frustoconical bores, one or more bores being evenly distributed around a central bore or around a group around the bottom axis on a circle of distributed bores; except for the central hole, all holes run obliquely away from the axis, so that there are conical beams for the blowing agent.
  • the invention provides that in the case of bores arranged on one or more circles around a central bore, the center distance (a1) of the bores lying in the same circle increases in a ratio of 1.5 to 2.5, preferably 1.8 to 2.2 the diameter of the outlet end (dA) of the holes.
  • the radial distance (a2) of the centers of the boreholes of adjacent circles and the centers of the boreholes of the inner circle from the axis of the central bore is in a ratio of 1.3 to 2.2, preferably 1.8 Diameter of the exit end (dA) of the holes.
  • the invention further provides that the ratio of the square of the diameter (dE) of the inlet side of the holes to the square of the diameter (dA) of the outlet end of the holes is between 0.25 and 0.65, preferably between 0.35 and 0.50 .
  • this conical beam is determined by the inclination of the holes in the nozzle that form the outer circle, which form the opening angle 2x of a cone. If r is the radius of the circular opening of the template which can be closed by a flap and L is the distance of the said cone tip from the center of the opening, then
  • the opening angle IX increases somewhat dimensioned. In the tests, it was found that there is optimum suction over a wide range of vapor pressures if, when selecting the opening angle IX for the spray cones in the formula mentioned, 0.9 times the value of L is used instead of L.
  • 1 and 2 represent a nozzle in which there are six further, obliquely downward-directed bores around a central bore in a circle.

Claims (4)

1. Buse d'injection à plusieurs ouvertures se présentant sous la forme d'un pot avec le fond percé, monté dans la conduite reliant la conduite montante et le collecteur de gaz sur des fours à coke, comportant des perçages élargis en forme de troncs de cône pour insuffler un agent propulseur compressible, de préférence de la vapeur, caractérisée en ce que dans le cas de perçages disposés autour d'un perçage central sur un ou plusieurs cercles, la distance de centre à centre (a1) des perçages se trouvant sur le même cercle sont dans un rapport de 1,5 à 2,5, de préférence de 1,8 à 2,2, avec le diamètre de l'extrémité de sortie (dA) des perçages.
2. Buse d'injection à plusieurs ouvertures suivant la revendication 1, caractérisée en ce que la distance radiale (a2) des centres des perçages de cercles voisins et des centres des perçages du cercle intérieur par rapport à l'axe du perçage central est dans un rapport de 1,3 à 2,2, de préférence de 1,8, avec le diamètre de l'extrémité de sortie (dA) des perçages.
3. Buse d'injection suivant l'une des revendications 1 ou 2, caractérisée en ce que le rapport du carré du diamètre (dE) du côté entrée des perçages au carré du diamètre (dA) de l'extrémité de sortie des perçages se trouve entre 0,25 et 0,65, de préférence entre 0,35 et 0,50.
4. Agencement de la buse d'injection à plusieurs ouvertures suivant les revendications précédentes dans la conduite reliant la conduite montante et le collecteur de gaz, caractérisé par une inclinaison des perçages sur le cercle extérieur telle que le faisceau de rayons produit par la buse ne remplit complètement la section transversale de la conduite de liaison qu'au niveau du passage dans le collecteur de gaz.
