Definitions

the invention relates to a Doppeldrallsprühdüse with two swirl chambers for generating spray with opposite spin as well as with a common inflow channel, which is in a median plane between the swirl chambers and each tangent in the swirl chambers empties.
a double-twist spray nozzle according to the preamble of claim 1 is known from document FR 882 080. Nozzles of this type become particular, as do other double jet spray nozzles according to DE 197 58 526 A1, mainly for so-called Gas scrubber used in which a washing liquid over a Variety of spray nozzles distributed as evenly as possible in the gas stream is introduced across the cross section.
gas scrubbers can, for example Flue gas cleaning systems are in which acidic flue gas components like sulfur dioxide, chlorine or hydrogen fluoride as well to a lesser extent also flue gas dust by using appropriate Washing liquids are deposited.
the nozzle assembly in such scrubbers is on several levels distributed, with the gas in the scrubbers usually from below flows upward and the atomized medium down, ie against the gas flow drops.
the gas in the scrubbers usually from below flows upward and the atomized medium down, ie against the gas flow drops.
the lower area are the previously mentioned Double-twist spray nozzles according to DE 100 33 781 C1, while in the upper area only to one side, that is, down, spraying Eccentric nozzles be provided to avoid being in the top End of scrubbers, especially flue gas desulphurisation plants sprayed droplet separator is sprayed.
Such eccentric nozzles generally have the following disadvantages: Da often the same volume flow as in the double-jet spray nozzles in lower range is desired, this must now by a swirl chamber (Mouthpiece) to be sprayed; this causes the droplet spectrum to coarsen, which can adversely affect the process. Want keep the drop spectrum constant and therefore halve the volume flow per nozzle, so you have to place twice as many nozzles, which at high cost (fasteners, mounting, pipe socket) can lead. Since the twisting direction of all eccentric nozzles is rectified, a spin is formed on the gas flow, which - as indicated above - can negatively affect the leaching.
both swirl chambers are open to the same side. Surprisingly, it has become thereby showing that in this case because of the common Inflow channels of the adjacent swirl chambers already short after exiting mutually overlapping sprays to none lead to adverse development of the resulting Sprühfumbleers. Because the Drops of directly adjacent spray cone through the small Distance of the swirl chambers quasi unopposed, leads the oppositely directed radial velocity of the drops so to a shock, that the drops burst and thereby the Drop spectrum refines. This effect is traditional arranged nozzles with a distance of 700 - 1200 mm to each other also present, but due to the air resistance there slowed radial speed is less pronounced. By the The invention therefore produces a droplet spectrum which leads to an improved Efficiency contributes. Since the twist chambers themselves only for half Volume flow can be designed, the overall length and so that also reduces the forces acting on the nozzle connection moments become.
the axes of the swirl chambers in at an angle to each other, towards the exit sides opens.
This embodiment allows an enlargement of the Spraying covered area. The danger of being untreated Gas strands pass through the scrubber, is thus reduced.
the new Double vortex spray nozzle is very compact and effective. It has shown that when the setting angle of the axes of the swirl chambers about 20 °, a particularly advantageous spray jet training can be achieved.
Figures 1 to 3 show that the new double-twist spray nozzle has a compact housing 1 with a connecting piece 2, the outside is provided with a connection thread 3, which with a Connection nut of an inflow pipe, not shown, can be screwed.
the housing 1 encloses two mirror-symmetrical to that of FIG. 2 apparent center plane 4 trained swirl chambers 5 and 6, respectively pass into trumpet-shaped outlet openings 5a, 6a.
the axes 7 and 8 of the swirl chambers 5 and 6 are against each other inclined at an angle ⁇ , which is 20 ° in the embodiment.
the flow channel 10 of the connecting piece goes 2 without significant cross-sectional constriction in the two swirl chambers 5 and 6, both open to the same side.
the connecting piece 2 supplied beam of the liquid used Medium - depending on the application for the relevant Gas scrubber is selected - meets the against its flow direction pointing cutting edge 9 on.
the beam is therefore split into two parts, one of them right through the swirl chamber 6 and the other is introduced to the left in the swirl chamber 5, from where then the spray jet outlet in the form of a spray cone after the same Page done.
the flow channel 10 goes on the of the cutting edge. 9 opposite side behind an edge 11 in the respective swirl chamber fifth and 6, it forms an intersection with the associated swirl chamber.
the two Spray jets have an opposite twist and overlap in the facing area. There, despite the rectified, circumferentially acting velocity vectors because of the opposing radial velocity a secondary decomposition the liquid droplets formed in the spray jet take place, As already mentioned, which has a positive effect on the efficiency the gas cleaning effect.
the invention can now only by mounting a single nozzle to achieve a spray extension as well as an interaction the mutually overlapping and with different Swirling spray cone, the beneficial effects on the cleaning efficiency Has.
