Date Nov. 2, 1989.A spray device is described in which the water spray from a water chamber is supplied to a spray head by cylindrical tubes inducing a head loss. The water from the tubes is guided by additional tubes into a water outlet channel forming a continuous slot. Water ejection mechanism are mounted on either side of the slot and in the air conduits. The water ejection mechanism are formed by vanes in which the flow of spray water is guided perpendicularly to the surface of the item to be treated. The vanes, which are segment shaped, are placed end to end along the length of the slot and form converging conduits for the air, ending in rectangular slot openings. A second embodiment is given for a vertical jet spray. |
