<p>Spray nozzle has a spray heat mounted in a passage, while a plate oscillating at high frequency acts as a sound emitter, being mounted parallel to the flow direction. The spray head (6) is mounted at the inlet (5) to a passage (1) of constant cross-section, while the emitter (3) is accommodated in a boss (2) to the side and outside the passage. Head and passage can be mounted in a free current, and the passage can be a smooth pipe, enclosed by an outer pipe (8) at a constant distance from it, and which protrudes beyond it in both upstream and downstream directions.</p> |
