Spray lance arrangement

Abstract

A two media spray lance and nozzle useful for moistening at least a portion of absorbent material present in a mixer. The nozzle includes a central body with a connecting portion for connecting the nozzle to the two media spray lance for a supply of liquid and gas thereto, and an atomizing portion. The atomizing portion delivers droplets of liquid to the absorbent material present in the mixer to obtain moistened absorbent material.

1 . A method of atomizing a liquid comprising:
 supplying a liquid dispersed by air to a nozzle comprising a central body comprising a connecting portion for fluidly connecting the nozzle to a supply of liquid and a supply of air for dispersing the liquid to form air dispersed liquid prior to flow into the nozzle, and an atomizing portion for forming droplets of the air dispersed liquid flowing from the connecting portion to the atomizing portion of the nozzle; and   atomizing the air dispersed liquid using the nozzle to form an essentially flat spray of liquid droplets from the nozzle.   
     
     
         2 . A method according to  claim 1 , wherein the nozzle further comprises a cleaning chamber defined by the atomizing portion. 
     
     
         3 . A method according to  claim 1 , wherein the nozzle further comprises a deflecting plate with a deflection surface having a surface roughness, R a , of 0.01 to 2.0 micrometer. 
     
     
         4 . A method according to  claim 3 , wherein an angle α between the deflection surface and a center line of the liquid supply pipe is in the range of 15-25°. 
     
     
         5 . A method according to  claim 3 , wherein the deflecting plate has lateral edges extending from the deflection surface at an angle γ of 10-40° to a normal line of the deflection surface.
