A device for realizing integration and control of multi-nozzles comprises a sprinkling rod (1) provided with a group of nozzle mounting holes (2) and disposed along rod length, and a group of nozzles (3) mounted in the nozzle mounting holes. A liquid medium cavity (4), a steam source cavity (5), and a medium refluxing cavity (6) are communicated with each other and respectively opened in the sprinkling rod along axial direction. The liquid medium cavity (5) and the steam source (5) are respectively communicated with each nozzle along the radial direction, the liquid medium cavity (5) and the medium refluxing cavity (6) are communicated via a passage arranged on a head of an end of the sprinkling rod, and a group of control gas cavities (7) provided with pneumatic control valves is disposed on the sprinkling rod. The control gas cavities are communicated to one another via the pneumatic control valves and respectively control a nozzle. The nozzle includes a valve body (3a) and a spray head (3b), a medium passage (3c) and a steam source passage (3d) respectively communicated to the liquid medium cavity and the steam source cavity, and a valve core disposed in the nozzle inner cavity and being capable of moving in lateral direction. Each nozzle in the invention can be independently controlled to realize multipoint low volume spraying, and the inventive device has adjustable atomizing region, good spraying effect, compact structure, and convenient maintenance.
