Safety Device for Circulating Water Utilization System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circulating-water utilization systems rely on public waterworks and sewer systems, making them unsuitable for stable operation independently, especially when abnormalities occur in the purification units.
Innovation Solution
A safety device for the circulating-water utilization system that includes a monitoring unit to detect water quality and treatment vessel abnormalities, a shutoff valve to prevent deteriorated water supply, and a switching mechanism to divert flow around faulty treatment vessels, ensuring continuous and safe water supply by integrating with the public waterworks system when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the circulating-water utilization system operates independently from public waterworks and sewer systems, then water resource efficiency is improved, but system reliability deteriorates when abnormalities occur in purification units
Solution Approach 1:
The purification unit is divided into multiple treatment vessels arranged in series, allowing the system to process water through sequential stages. This segmentation enables isolated monitoring and maintenance of individual vessels while maintaining overall system operation.
Solution Approach 2:
The safety device continuously monitors water quality and treatment vessel status before abnormalities affect the entire system. By detecting issues early and initiating corrective actions in advance, the system maintains reliability without requiring complex redundant purification infrastructure.
2Reliability
If multiple treatment vessels are connected in series for purification, then water quality is improved, but the risk of system failure increases when abnormality occurs
Solution Approach 1:
The circulating-water monitoring unit continuously measures water quality parameters and feeds this information back to the safety device. The treatment-vessel monitoring unit similarly provides feedback on vessel status, enabling real-time detection and response to quality deterioration or abnormal conditions.
Solution Approach 2:
The safety device acts as an intermediary between the treatment vessels and the water supply system. It receives monitoring data from treatment vessels and controls the shutoff valve and switching mechanisms to prevent deteriorated water from reaching consumers, thereby mediating between purification processes and water quality protection.
3Reliability
If a shutoff valve is installed to prevent deteriorated water supply, then water safety is improved, but system operability deteriorates due to supply interruption
Solution Approach 1:
The system dynamically switches between circulating water supply and tap water supply based on real-time water quality conditions. The switching mechanism and control unit adjust the water source automatically, maintaining ease of operation and supply continuity while ensuring water safety through the shutoff valve when deterioration is detected.
