The full cone nozzle means that the spray shape is conical, and any area inside the cone has a uniform droplet distribution.

The hollow cone nozzle means that the spray shape is a cone, but there is no droplet distribution inside the cone, and the droplets are only distributed on the edge of the cone.

From the picture above, we can see that the coverage cross section of the full cone nozzle is a circle, while the coverage cross section of the hollow cone nozzle is a ring. Due to this difference, the application scenarios of the two nozzles are different. The full cone nozzle with larger coverage area is suitable for fixed spray mode, that is, the relative position of the nozzle and the sprayed object is fixed.Because of its huge coverage area, it can be sprayed evenly on the surface of the object to achieve complete spray coverage.

The hollow cone nozzle is suitable for mobile spray mode, that is, the relative position of the nozzle and the object being sprayed moves. For example, a hollow cone nozzle is installed above the conveyor belt. Since the object and the nozzle move relative to each other, the hollow cone nozzle can also be used. Spray to any position of the object. In addition, the hollow cone nozzle can also be used to isolate the spray. For example, the hollow cone nozzle is installed in a circular chimney. The ring sprayed by the nozzle is covered in the chimney like a hat, making the nozzle The air below and the air above are separated by a water curtain to filter out particles in the exhaust gas and cool the chimney at the same time.
