NOZZLE APPARATUS AND METHOD FOR ATOMIZING FLUIDS

摘要

An atomizing nozzle for a fire suppression system, having a nozzle body and a deflector body secured together. A flow passage defined between the deflector body and nozzle body extends radially outwardly from an inlet port to a circumferential outlet slot, the outlet slot being defined between the nozzle body and deflector body and extending at least partially around the. Vanes are disposed in the flow passage, and are arranged so as to impart to fluid flowing through said flow passage a tangential velocity component relative to the axis of the flow passage. The vanes may be arranged such that the tangential velocity component is sufficient to impart to gas in the area a rotational motion about the axis. The vanes may be removable, and may be retrofitted to existing nozzles. The nozzles also may be removable, and may be retrofitted to existing fire suppression systems.
