Fluid ejector device for vessels

Abstract

The disclosure relates to a fluid ejection device and a method for ejection of fluid into a marine environment. The device includes at least one foldable ejection arm with at least one fluid ejection nozzle, the arm(s) being mounted on a transport vessel in one or several mounting points. Furthermore, the ejection arm is foldable, where the folded position of the arm(s) is essentially along the longitudinal direction of the transport vessel.

1 . A fluid ejection device for ejection of fluid into a marine environment comprising
 at least one foldable ejection arm having at least one fluid ejection nozzle, said at least one foldable election arm being mounted onto a transport vessel in one or several mounting points   and being foldable into a folded position arranged essentially along the longitudinal direction of the transport vessel.   
     
     
         2 . The fluid ejection device according to  claim 1 , wherein at least one of the ejection arms is telescopically configured in order to render adjustments of length possible. 
     
     
         3 . The fluid ejection device according to  claim 1  wherein the transport vessel is a ship. 
     
     
         4 . The fluid ejection device according to  claim 1 , wherein the foldable arm constitutes an integrated part of the transport vessel. 
     
     
         5 . The fluid ejection device according to
   claim 1 , wherein   at least one of the following parameters is adjustable by one or several users of the arm,
 a direction of the ejected fluid from one or several of the nozzles, 
 an amount of fluid or fluid flow ejected from one or several of the nozzles, 
 an opening dimension on one or several of the nozzles, 
 a fluid velocity out from one or several of the nozzles, and 
 an the-angle (α, α′) between a transverse axis oriented perpendicular to a height axis and the longitudinal direction of the transport vessel, and a longitudinal axis of the ejection arm(s). 
   
     
     
         6 . The fluid ejection device according to  claim 1 , wherein the foldable arm is lockable in its folded position in order to avoid undesired unfolding. 
     
     
         7 . The fluid ejection device according to  claim 1 , wherein the foldable arm is stabilized in a desired position outward from the transport vessel by use of a stabilising device. 
     
     
         8 . The fluid ejection device according to  claim 7 , wherein the stabilizing device comprises one or both of a hydraulic device and a hinge system. 
     
     
         9 . The fluid ejection device according to  claim 1 , wherein a desired operative position of a longitudinal axis of the foldable arm(s) lies within an angle area from 0° to 85° relative to a transverse axis oriented perpendicular to a height axis and the longitudinal direction of the transport vessel, the operative position being defined as the position in which fluid is ejected from one or several of the nozzles. 
     
     
         10 . The fluid ejection device according to  claim 1 , wherein the one or several mounting points on the transport vessel is oriented in or near a horizontal, transverse centroidal axis of the transport vessel. 
     
     
         11 . The ejection device according to  claim 1 , wherein fluid for ejection includes a dissolution liquid such as dispersals liquid. 
     
     
         12 . The ejection device according to  claim 1 , wherein the marine environment is sea water. 
     
     
         13 . A method for ejection of fluid into a marine environment by the use of a fluid ejection device the method comprising:
 detaching at least one foldable ejection arm from a folded/inactive position,   unfolding the at least one foldable ejection arm to an active position,   adjusting nozzles of the at least one foldable election arm to obtain desired through-put and/or direction of the ejected fluid, and   stabilizing the at least one foldable ejection arm in its folded/inactive position.   
     
     
         14 . The method according to  claim 13 , wherein said stabilizing and detaching is performed by use of a dedicated stabilizing system and a dedicated locking mechanism, respectively. 
     
     
         15 . The method according to  claim 13 , further comprising adjusting a length of the at least one foldable ejection arm.
