Rotating Nozzle Assembly for Liquid Cloud Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for generating a cloud of liquid, such as water, are not simple and reliable enough for applications like fire extinguishing systems, as they require complex mechanisms and materials that are not versatile for other technical fields.
Innovation Solution
A rotating nozzle element with a cylindrical body and freely rotating nozzle, activated by pressurized air and a blocking piston mechanism, which creates a cloud of water by rotating and spraying it through strategically placed outlets, allowing for adjustable pressure and flow rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanism is used to generate a cloud of liquid, then the system can achieve the desired liquid dispersion, but the system complexity and material requirements increase significantly
Solution Approach 1:
The nozzle is divided into multiple independent channels, each with its own outlet oriented at a specific angle. This segmentation allows each channel to function independently, simplifying the overall mechanism while maintaining reliable cloud generation through the coordinated action of multiple simple components rather than one complex mechanism
Solution Approach 2:
The nozzle is designed to rotate dynamically, changing the orientation of all outlets simultaneously. This dynamic rotation creates a distributed liquid cloud pattern over time, achieving reliable dispersion through motion rather than through complex static mechanical structures
2Reliability
If a rotating nozzle mechanism is implemented, then liquid cloud generation is achieved, but the system may lack versatility for other technical fields
Solution Approach 1:
The nozzle design with multiple angularly-oriented channels and rotation capability creates a universal liquid dispersion mechanism that can be applied across different technical fields including fire extinguishing, agricultural spraying, and industrial cooling. The fundamental principle of rotating multi-directional spray remains effective regardless of the specific application context
Solution Approach 2:
The system allows adjustment of rotation speed, liquid flow rate, and channel orientation angles. By changing these parameters, the same nozzle structure can adapt to different applications requiring varying cloud densities, spray patterns, and coverage areas, thereby achieving versatility without sacrificing cloud generation consistency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively generates a consistent and controlled cloud of water for fire extinguishing and other applications, maintaining pressure and flow rate, and can be adapted for various liquids and gases, with versatile material options.
Implementation Method 1
The ducts 10 also comprise at least one, but preferably several, side outlet(s) 11 for the air which make it possible to create the rotation relative to the body, in the manner of a propeller.
Implementation Method 2
the pressurized water is evacuated through the small nozzles 16 ( figure 4 ) which open above the openings 11 which in turn allow pressurized air to escape. Preferably, in order to maintain a constant pressure in the nozzle and an identical flow rate at the level of the small nozzles 16, a regulator coupled to the device is used. Thus, the rotating nozzle creates a cloud of water by rotation generated by the air and spraying of the water coming out of the nozzles 16.

AI summary
The element (1) has a cylindrical body (2) forming a cage and supplied with gas i.e. air, and liquid i.e. water. A rotating nozzle (3) is mounted on bearings (4, 5) in the body. The rotating nozzle comprises two pipes (10, 15) supplied with gas and liquid from a lateral gas nozzle (11) and a small liquid nozzle, respectively. The ejection of gas through the gas nozzle permits rotation of the rotating nozzle and spraying of the liquid from the small liquid nozzle.
