Overflow Pipe Dechlorinating Device with Adjustable Conduit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a reliable device that can automatically remove disinfectants like chlorine from water discharged through overflow pipes in public water systems to prevent harm to aquatic life and provide security against potential terrorist attacks by ensuring the water is dechlorinated before entering natural water bodies.
Innovation Solution
A dechlorinating device with a mixing chamber, dechlorinating conduit, and recirculation zone is installed on overflow pipes, featuring a conduit with adjustable inner and outer sections and a conduit screen containing dechlorinating materials like ascorbic acid, which effectively dechlorinates water while preventing clogs and providing a dual duckbill valve configuration for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dechlorinating materials are placed in the overflow pipe, then disinfectant removal is achieved, but clogging occurs
Solution Approach 1:
The dechlorinating conduit is divided into an outer conduit and an inner conduit, creating segmented flow paths. The inner conduit contains screens with openings that allow water to pass through while filtering out debris, preventing clogs while maintaining dechlorination effectiveness.
Solution Approach 2:
Conduit screens are introduced as intermediary elements between the dechlorinating materials and the water flow. These screens filter the water and prevent debris from clogging the system while allowing the dechlorination process to continue effectively.
2Ease of manufacture
If a fixed dechlorinating conduit is used, then simple installation is achieved, but adaptability to different flow rates is limited
Solution Approach 1:
The inner conduit is made rotatable within the outer conduit, allowing the system to dynamically adjust to different flow rates and conditions. This rotational capability enables the conduit to adapt its configuration while maintaining a relatively simple overall structure.
Solution Approach 2:
The inner conduit is nested within the outer conduit, creating a compact structure that is easy to install. The nested design allows the inner conduit to rotate independently while maintaining the overall simplicity of the assembly.
3Ease of operation
If overflow pipes discharge directly to stormwater systems, then simple discharge is achieved, but harm to aquatic life occurs
Solution Approach 1:
The device converts the harmful chlorinated water into beneficial dechlorinated water by passing it through the dechlorinating conduit containing dechlorinating materials. This transforms the harmful discharge into a safe discharge that protects aquatic life while maintaining the simplicity of the discharge process.
4Reliability
If security measures are added to protect against contamination, then security is improved, but device complexity increases
Solution Approach 1:
The dechlorinating conduit serves multiple functions: it dechlorinates water, filters debris through screens, prevents clogs, and provides security against contamination. This multi-functionality reduces the need for separate security devices while maintaining overall device simplicity.
