A double-fluid double-channel nozzle special for a large-sized roller and a support roller spray quenching machine

This application discloses a dual-fluid, dual-channel nozzle specifically designed for large roll and support roll spraying quenching machines. It mainly comprises a nozzle body, spiral guide vanes, a mixing chamber, and a diffusion nozzle. This invention features gas-liquid swirling mixing, filtration, backwashing, and self-cleaning effects. Clean water passes through the filter element and is spirally turbulent by an array of spiral turbulence vanes A, creating a central spiral flow field. The airflow, after being guided through the annular cavity between the nozzle body and the guide chamber, enters the space between the fixed sleeve and the outer wall of the cavity, where it is spirally turbulent by the spiral array of spiral turbulence vanes B, forming a uniformly distributed annular swirling field. The gas and liquid phases ultimately mix and contact inside the diffusion nozzle of the mixing chamber. The gas swirling flow, carrying tangential velocity, surrounds the water flow on its outer edge, while the water swirling flow, carrying circumferential velocity, diffuses from the center outwards, creating a collisional envelopment with the annular airflow. The velocity difference between the two swirling flows generates continuous shear force at the gas-liquid interface, constantly breaking up the water flow.
