Definitions
- 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.
- 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.
- 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.
- 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.
- 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 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.
- ⁇ denotes the cone opening angle, which forms the measure of the frustoconical widening of the bores.
- 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.
- 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 °.
- 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.
- the multi-hole pressure nozzle should be arranged within the elbow to be easily adjustable 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, 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 .
- 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.
