Atomizing cool-down nozzle

The utility model provides an atomizing cool-down nozzle, which belongs to the field of petrochemical equipment and coal chemical equipment. The utility model includes a swirl nozzle, a swirl chip, a water inlet pipe, a suction piece, a gas inlet, a water inlet and a spray hole; and the utility model uses a solid atomizing swirl chip for causing the liquid granule to cover the entire injection surface uniformly; the utility model uses a tangential swirl air-intake atomizing structure, thereby strengthening film spreading and breaking of liquid. The device is used for cool-down of flue gas or synthesis gas whose temperature is above 500 DEG C. in the FCC device of petrochemical factory and coal chemical process, and the cool-down effect is good without disadvantage effect for the technological operation and damage for the apparatus, in addition the device has the advantages of simple structure, long service life, low water consumption without pollution.
