Hollow Cone (Whirlchamber-Type) Nozzle
Product Overview
The hollow cone (whirlchamber-type) nozzle is an industrial spray nozzle that uses an internal whirlchamber to rotate the fluid at high speed, producing a hollow cone spray pattern. The spray forms a circular ring distribution with small droplet size and high flow capacity, making it ideal for applications requiring a combination of fine atomization and high flow rates.
How It Works
Pressurized liquid enters the internal whirlchamber, where it is set into high-speed rotational motion. As the liquid exits the orifice, centrifugal force creates a hollow cone spray pattern. The liquid is distributed primarily along the circular edge of the spray cross-section, leaving the center hollow, with fine and uniform droplet size.
Typical Applications
-
Air, Gas & Water Cooling: Fine droplets rapidly evaporate, removing heat efficiently
-
Product Cooling on Conveyors: Uniform coverage for effective temperature reduction
-
Dust Control: Fine droplets effectively capture airborne dust particles
-
Flue Gas Desulfurization (FGD): High capacity with fine droplets improves absorption efficiency
-
Water Aeration: Increases dissolved oxygen in water bodies
-
Chemical Spraying: Gas-liquid reactions, scrubber tower spraying
