UV Fluid Treatment Device with Branch Flow Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ultraviolet light fluid treatment devices have limitations in enhancing the treatment effect due to inadequate distribution and intensity of ultraviolet light within the fluid flow channels, leading to inefficiencies in bacterial and viral reduction.
Innovation Solution
The ultraviolet light fluid treatment device incorporates multiple branch flow channels that merge into a single channel, with both first and second light sources emitting ultraviolet light along the flow path, increasing the integrated luminance and retention time of fluid within the treatment area, thereby enhancing the treatment effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single flow channel is used with one light source, then the device structure is simple, but the treatment effect is insufficient due to inadequate ultraviolet light distribution and intensity
Solution Approach 1:
The flow channel is divided into multiple branch flow channels (first, second, third branch flow channels) that merge into a merged flow channel. Multiple light sources (first light source for merged channel, second light sources for branch channels) are distributed throughout the system to provide comprehensive ultraviolet irradiation, ensuring adequate treatment effect while maintaining reasonable structural complexity
Solution Approach 2:
Multiple branch flow channels are merged into a single merged flow channel, allowing fluid to receive ultraviolet treatment in both branch and merged sections. The treatment effects from multiple light sources are combined to achieve enhanced overall disinfection performance
2Illumination intensity
If multiple light sources are distributed throughout the flow channels, then the integrated luminance and treatment effect are enhanced, but the device complexity increases
Solution Approach 1:
Light sources are strategically positioned in specific locations: the first light source is placed for irradiating the merged flow channel while the second light sources are positioned to irradiate the branch flow channels. This localized placement optimizes ultraviolet distribution and treatment effectiveness without unnecessarily increasing overall device complexity
