ABSTRACT:
A double-swirl spray nozzle includes two swirl chambers which are connected to a common supply channel which extends in a central plane between the swirl chambers. Both swirl chambers have outlet openings which open outwardly from the supply channel to the same side. The axes of the swirl chambers are furthermore inclined at an angle with respect to one another. Thus with one single compact spray nozzle it is possible to create atomizing cones with a very large impact area which mutually overlap on the side facing one another and in spite of the speed component unidirected in the overlapping area result in a secondary division of the liquid droplets in the two atomizing cones, which increases the efficiency when the nozzle is utilized in so-called gas washers for cleaning purposes.
