Feeder device for feeding aqueous acrolein solution to a main ballast water line of a ship

Abstract

Feeder device for feeding aqueous acrolein solution to a main ballast water line of an apparatus for treating for an apparatus for shops for treating ballast water with acrolein comprises an annular nozzle which is dimensioned for usage in the main ballast water line, wherein the annular nozzle comprises a nozzle ring comprising a plurality of nozzle openings distributed over the interior circumference of the nozzle ring.

What is claimed is: 
     
         1 . Feeder device for feeding aqueous acrolein solution to a main ballast water line of an apparatus for treating for an apparatus for ships for treating ballast water with acrolein comprising an annular nozzle which is dimensioned for usage in the main ballast water line, wherein the annular nozzle comprises a ring nozzle comprising a plurality of nozzle openings distributed over the interior circumference of the ring nozzle. 
     
     
         2 . Feeder device according to  claim 1 , wherein the plurality of the nozzle openings is distributed over the interior circumference of the ring nozzle are arranged under equal distances. 
     
     
         3 . Feeder device according to  claim 1 , wherein the interior diameter of the ring nozzle is adapted to the interior circumference of the main ballast water. 
     
     
         4 . Feeder device according to  claim 1 , wherein the feeding device comprises additionally a flow interfering device arranged at the ring nozzle which stream interfering device is located downstream of the ring nozzle in direction of a main ballast water stream flowing in the main ballast water line. 
     
     
         5 . Feeder device according to  claim 4 , wherein the flow interfering device comprises a mixing face plate having an opening for the main ballast water stream, wherein the opening has a smaller opening area than the free inner cross section area of the main ballast water line. 
     
     
         6 . Feeder device according to  claim 5 , wherein the opening of the mixing face plate is not circular. 
     
     
         7 . Feeder device according to  claim 1 , wherein the feeding line of the ring nozzle is formed as an injector line which is tangentially arranged at the ring nozzle.
