Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzles fail to effectively prevent turbulent flow, maintain uniform jetting patterns, and improve collision force, leading to inefficient scale removal on steel plates due to inadequate rectifying members and increased pressure loss.
Innovation Solution
A rectifying member with a lattice-shaped partition wall structure that subdivides the fluid flow path into multiple units, using circumferential and inside division walls to enhance fluid rectification, density, and collision force, while preventing clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional rectifying member with simple radial blades is used, then the structure is simple, but the turbulent flow cannot be effectively prevented and the jetting pattern becomes irregular
Solution Approach 1:
The rectifying member is divided into multiple independent blade elements arranged in circumferential rows, with each blade acting as a separate flow rectification unit. This segmentation allows better control over turbulent flow while maintaining structural simplicity
Solution Approach 2:
The blade elements serve as intermediary structures between the turbulent flow in the header and the required uniform jetting pattern at the discharge port, mediating the flow transformation through their specific geometry and arrangement
2Force
If the rectifying member is designed to increase droplet density, then the collision force improves, but the device complexity increases
Solution Approach 1:
The blade elements have specific local geometries with optimized thicknesses and angles in different regions, creating localized flow control characteristics that increase droplet density and collision force without requiring complex overall structure
Solution Approach 2:
The rectifying member utilizes circumferential arrangement of blades in addition to radial extension, adding a circumferential dimension to the flow control mechanism that enhances droplet density while maintaining structural simplicity
3Area of stationary object
If the discharge port uses an anisotropic flat pattern to cover wide steel plates, then the coverage area increases, but the flow rectification becomes more difficult
Solution Approach 1:
The blade elements are arranged with asymmetric circumferential spacing and varying radial lengths to accommodate the anisotropic flat discharge pattern, enabling wide coverage while maintaining effective flow rectification across different directions
4Productivity
If the jet water speed is maintained high for effective scale removal, then the scale removal efficiency improves, but the turbulence in header causes irregular fluctuation reducing the actual effectiveness
Solution Approach 1:
The rectifying member performs preliminary flow conditioning in the header, straightening and stabilizing the water flow before it reaches the discharge port, ensuring uniform high-speed jetting for effective scale removal
