The invention discloses a striking and self-exciting oscillation high-thickness fluid two-phase spraying nozzle. The striking and self-exciting oscillation high-thickness fluid two-phase spraying nozzle comprises a spraying nozzle body, a gas flow inlet pipe and four striking injectors. High-thickness fluid firstly enters the striking injectors for striking atomization so as to form a liquid film. Air flow flows in from the gas flow inlet pipe, acts on the liquid film and enables the liquid film to be smashed into small liquid drops. The air flow carries the liquid drops to enter an oscillation cavity in the spraying nozzle body, the air flow is subject to high-frequency oscillation in the oscillation cavity, and the liquid drops are further smashed. Finally, the air flow carries the small liquid drops to spray out the small liquid drops from a through hole in an oscillation device, and atomization is completed. The oscillation device can slide in the spraying nozzle body and is compressed and fixed through a
