Definitions

  • the invention relates to a fluid operated rlochdruckdüse eh M, the shape of a pot with a perforated bottom and is installed into the manifold, the coke ovens in connecting the riser and the template.
  • each individual furnace chamber is connected to the template, not only is ammonia-containing liquid introduced, which is under a pressure of a few bar, during operation of the ovens, but also a nozzle built into the elbow is used for this purpose, During the filling of the ovens, the gases which develop in the process are sucked off through the upper gas collecting space and the riser pipe by means of a nozzle into the receiver using very high pressure.
  • 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 arrangement is characterized in that when using certain high pressures and certain, given in the time unit, maximum gas quantities are sucked off as the propellant of liquid quantities.
  • the frustoconical design according to the invention occurs of the bores a resolution of the liquid jets after exiting the nozzle, through which a particularly large amount of gas is entrained by the liquid.
  • 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.
  • the riser pipe is designated 10, the template 11, and the manifold 12.
  • the multi-hole pressure nozzle 13 is inserted in its upper wall.
  • the liquid cone is designated, which is generated by the liquid applied.
  • d E is the hole diameter of the holes on the water inlet side
  • d A is the hole diameter of the holes on the water outlet side.
  • d 1 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.
  • d 2 the diameter of the circumferential circle is designated on the water outlet side, ie the circle that affects the circles designated with the diameter d A from the outside, which form the outlet openings of the bores.
  • ⁇ is the cone opening angle, which forms the dimension of the frustoconical expansion of the holes.
  • 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 ( ) 2 have a value between 0.4 and 0.85, preferably between 0.65 and 0.7.
  • the ratio mentioned is obviously a measure of the Er extension of the hole.
  • the expansion can be faster or slower, depending on the length of the bore, ie the thickness of the bottom of the nozzle.
  • 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 °.
  • the ratio of the diameter d 1 of the circumferential circle of the bores on the inlet side to the diameter d 2 of the circumferential circle on the outlet side ie the value between 0.5 and 0.95, preferably between 0.8 and 0.9.
  • the multi-hole pressure nozzle should be arranged within the elbow in such a way that it can be adjusted in height.
  • 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.
  • 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.
  • the center distance a 1 of adjacent boreholes with the diameter d A on the liquid outlet side is related to the diameter d A , the value of which is between 1.8 and 2.8, preferably 2.4 .
  • the radial spacing a 2 of the circles passing through the center of the boreholes of a ring of holes should be in a certain ratio to the diameter d A on the liquid outlet side, specifically should the relationship have a value which is between 1.5 and 2.6, preferably 2.1.
