SPRAY NOZZLE

PROBLEM TO BE SOLVED: To provide a spray nozzle which can reduce the size of spray particles and, at the same time, for example, in the case of the provision of the spray nozzle for cooling exhaust gas within a cooling tower in exhaust gas treatment equipment of a refuse incinerator, can reduce a production cost despite its structure that can solve a problem of a high tendency toward moistening of dust in exhaust gas. SOLUTION: A liquid flow passage 2 is provided in a nozzle body 1, and, in addition, a predetermined number of jetting ports 3 in communication with the liquid flow passage 2 are provided dispersively at the front end part of the nozzle body 1 around an axial center O of the nozzle body 1. A plurality of gas flow passages 4, which are in communication with the liquid flow passage 2 from its external side in the radial direction, are provided dispersively in the nozzle body 1 in its part around the liquid flow passage 2. A baffle member 5, that collides with a gas-liquid mixture which flows through the liquid flow passage 2 to atomize the gas-liquid mixture, is provided in a liquid flow passage part between a predetermined number of jetting ports 3 and the front opening part of the plurality of gas flow passages 4.
