  • Cleaning liquid can optionally be fed via the valves 146 and 147 into the compressed gas line 138.
  • the cleaning fluids are entrained by the pressure gas flow and first entered into the mixing chamber 7 via the through holes 5 for the compressed gas.
  • blow-off liquid 132 can be recirculated and is then pumped by the pump 154 into one of the containers 142, 143, for example.
  • liquid 1 to be sprayed is thus conveyed through the liquid supply line 125 to the nozzle lance 117 when the main liquid valve 121 is open. At the same time passes through the compressor 136 ambient air 115 through the valve 137 in the conduit 138 and the compressed gas supply line 4 of the nozzle lance 117. In the spraying operation, no cleaning liquid is supplied via the feed station 139 in the rule.
  • the compressed gas enters the annular chamber 6, which surrounds the mixing chamber 7 at least in sections and through the through holes 5 in the mixing chamber 7.
  • the liquid to be sprayed shoots through the constriction 10 of the liquid inlet bore centrally symmetrically in the mixing chamber 7 a. Another constriction 114 closes the mixing chamber 7 from the nozzle outlet 8 back. After Bottleneck 114 is adjoined by an outlet funnel, so that a spray jet exits through the nozzle outlet 8 into the process environment 116.
  • the main liquid valve 121 is turned off, and the purge valves 122, 123, 124 are opened.
  • the compressed gas supply is further maintained and the feed point 139 cleaning liquid from the containers 142, 143 is fed, so that in the compressed gas supply line 4, a mixture of cleaning fluid and compressed gas, especially ambient air 115 is located.
  • the main liquid valve 121 and opened cleaning valves 122, 123, 124 is at least a portion of the pressurized gas with the cleaning fluid through the mixing chamber 7 through the lance tube 2 and the feed line 125 to the filter 120 promoted and discharged from here into the Abschlämm constituer 126.
  • the compressed gas flowing into the mixing chamber 7 can emerge from the mixing chamber 7 via two openings in cleaning operation, once via the somewhat larger constriction 114 of the mixing chamber 7 to the gas space 116 or over the constriction 10 in the liquid supply line, namely the lance tube 2 and then to the filter 120 and the Abschlämm constitutioner 26 out.
  • Examinations by the inventor have shown that the dynamic pressure of the atomization air flowing towards the filter 20 for the removal of platelet-shaped shutters in the region of the constriction 10 together with the liquid 1 still present in the liquid feed line, the lance tube 2, back to the filter 120 in all Rule is quite enough.
  • This cleaning air stream can be intensified by applying a negative pressure to the blowdown container 126, which, as already described, takes place by opening the valve 127 and activating the pump 28.
  • the cleaning effect can be enhanced by applying pressure surges to the cleaning fluid.
  • one of the valves between the mixing chamber 7 and Abschlämm constituer 126 may be designed as a flutter valve.
  • cleaning liquid can also emerge from the nozzle mouth 8. This is usually desirable to replace deposits in the mouth region of the nozzle.
  • This cleaning liquid which enters the gas space 116 via the nozzle mouth 8, becomes even in the cleaning operation so finely sprayed that it is not dangerous for downstream components, since the drops are evaporated in time.
  • the partial flow of the cleaning fluid exiting via the nozzle mouth 8 can be lowered as far as desired by applying a sufficiently low negative pressure to the blowdown container 126. If necessary, one can also reduce the pressure of the atomizing air accordingly.
  • a method for operating the spray assembly 80 can be sucked through the nozzle mouth 8 through the liquid supply line, the lance tube 2, and the supply line 125 to the nozzle lance 117 by a sufficiently strong reduction of the negative pressure in the Abschlämm constituer 126 gas, if this with appropriate composition of Gas in the gas space 116, for example, a suitable flue gas composition, does not appear detrimental.
  • Zweistoffdüsennanzen are often fed not only with the liquid to be atomized and compressed gas, but also with Hüllluft, which is guided in a tube which surrounds the two-component nozzle lance concentric. During operation, this envelope air then encloses the nozzle orifice 8.
  • the sucking back of gas during the cleaning operation it is therefore not necessary for any flue gas to be sucked back over the nozzle lance in this case. Rather, the sucked back gas may consist of neutral enveloping air.
  • sucking back from Hüll Kunststoff thus it is possible to clean nozzles and nozzle lances without the cleaning liquid would need to get into the flue gas. And there does not always have to be flue gas in the gas space 16.
  • flue gas in the gas space 16 there may be a strong interest in not letting any cleaning liquid get into the food contact side of the food.
  • the cleaning liquid which makes up the largest percentage of the blowdown liquid 132 in the blowdown tank 126, can be recirculated via the pipe 133 and the pump 154 until their absorption capacity is exhausted, taking account of economic aspects. Therefore, cleaning liquid should only be blown through the nozzle mouth 8 in the gas space 116 so far, as is beneficial for the process or for the cleaning of the nozzle mouth 8 is necessary.
  • the blow-down liquid 132 which consists to a large extent of cleaning liquid, would have to be evaporated.
  • This can be done by mixing the Abschlämmmatikeit 132 in the main liquid stream 1 during the spraying operation.
  • the dosing liquid 132 into the main liquid stream 1 is expediently added in such a way that the blowdown liquid 132 exits from the nozzle mouth 8 in diluted form for ineffectiveness.
  • Abschlämmatkeit can be removed via the line 133 and mixed by means of the pump 154 and the dashed lines shown supply line 81 to be sprayed liquid 1. With extreme dirt and deposits can also be so by means of the supply line 81 a lot of cleaning liquid are fed, that virtually exclusively cleaning liquid is conveyed to the mixing chamber 7 and thereby causes a thorough cleaning.
