Hollow cone spray nozzles produce a ring-shaped spray pattern with fine to medium-sized droplets concentrated at the outer edges, and minimal droplets in the center. They are specifically designed for applications requiring a large surface area for liquid-gas contact or effective atomization at lower pressures.
Key Characteristics
Spray Pattern: A circular, ring-like pattern with a hollow center.
Droplet Size: Generally produce smaller droplets than full cone nozzles, facilitating quick heat transfer and efficient gas absorption.
Clog Resistance: Feature large, unobstructed flow passages which minimize clogging and allow for uniform distribution across a wide range of flow rates and pressures.
Atomization: Provide effective atomization of liquids even at relatively low operating pressures.
Common Applications
Hollow cone nozzles are used in processes where a fine mist and extensive liquid surface area are necessary.
Cooling: Used for cooling liquids, surfaces, and gases, as well as in cooling towers.
Gas Scrubbing and Cleaning: Highly efficient in flue gas desulfurization (FGD) systems and for cleaning/capturing suspended particles in gas streams.
Dust Control: Create a fine mist to capture and control airborne dust particles.
Fire Protection: Employed in certain fire suppression and sprinkler systems.
Absorption Processes: Used in chemical reactors and odor control systems where uniform liquid-gas contact enhances reaction efficiency.
