RBSC Full Cone Sprial nozzle
Working principle of silicon carbide spiral nozzle
When a liquid with a certain pressure and speed flows from the top down to the RBSC/SiSiC spiral nozzle, the liquid in the outer part hits the helicoid with a certain angle on the nozzle. This can change the spray direction away from the nozzle. The included angle (helix angle) between the streamline of the surface of the cone of the different layers and the center of the nozzle is gradually reduced. It is conductive to increase the covering area of the ejected liquid effectively.
The RBSC/SiSiC spiral nozzle is a commonly used to desulphurization and dedust. It can produce hollow cone and solid cone spray shape with the spiral angle from 60 to 170 degrees. By cutting and colliding with the continuously smaller spiral body, the liquid will turn into the small liquid into the cavity of the nozzle. The design of the passage from the import to the exit is not obstructed by any blade and guide. In the case of the same flow, the maximum unblocked diameter of the spiral nozzle is more than 2 times that of the conventional nozzle. This can reduce the occurrence of hindrance to the greatest extent.
