Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a system to safely and effectively remove liquid waste that has leaked and remains in concrete drums storing concentrated radioactive waste, which poses potential safety hazards.
Innovation Solution
A liquid waste removal system comprising a fixed support, transfer pipe, and crane for securing and draining the concrete drum, along with a drilling, filtering, and waste collection system to extract and separate liquid waste while preventing damage to the containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transfer pipe is inserted into the concrete drum to remove liquid waste, then liquid waste can be discharged effectively, but the container inside the drum may be damaged during the process
Solution Approach 1:
The transfer pipe is inserted through the concrete drum wall without penetrating the container, utilizing the space between the drum and container. The pipe navigates through the annular space or leaks paths without直接接触 the container, allowing waste removal while preserving container integrity.
Solution Approach 2:
The concrete drum itself serves as an intermediary structure that allows the transfer pipe to access liquid waste without directly contacting the container. The pipe exploits existing leakage paths or spaces within the drum-container system, using the drum structure as a protective barrier.
2Reliability
If the concrete drum is fixed securely to prevent movement, then safety is improved, but the drum cannot be tilted for effective liquid waste drainage
Solution Approach 1:
The support system transitions from a static fixed state during insertion to a dynamic tilted state during drainage. The drum can be securely held in a horizontal position for safe pipe insertion, then tilted to an angled position for effective gravity-driven waste drainage, optimizing both safety and operational efficiency at different stages.
Solution Approach 2:
The drum undergoes periodic position changes: first held fixed in a stable position for insertion operations, then tilted for drainage, and finally returned to a stable position. This periodic adjustment of the drum's orientation optimizes both safety during insertion and drainage efficiency during removal.
