Dynamic Tank Cleaning Spray Head with Soiling-Adaptive Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tank cleaning systems are inefficient and ineffective in ensuring uniform cleaning, particularly in areas with heavy soiling, leading to excess cleaning of lightly soiled surfaces and inadequate cleaning of heavily soiled areas, resulting in waste of time, energy, and cleaning fluid.
Innovation Solution
A tank cleaning system with a controlled spray head that varies the point of impingement and adjusts cleaning fluid flow and pressure dynamically, using a rotational position sensor and control module to optimize cleaning based on tank configuration and soiling patterns, allowing for precise monitoring and operation of the spray head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed spray head with uniform rotation is used, then the system is mechanically simple and robust, but it cannot provide adequate cleaning for heavily soiled portions while wasting resources on lightly soiled areas
Solution Approach 1:
The spray head system transitions from fixed uniform rotation to dynamic variable speed rotation. The controller adjusts rotation speed based on detected soiling levels, allowing the system to adapt cleaning intensity to different areas. Heavily soiled portions receive higher rotation speeds for more aggressive cleaning, while lightly soiled areas use lower speeds to conserve resources.
Solution Approach 2:
A sensor detects soiling levels on different portions of the tank interior and provides feedback to the controller. The controller processes this information and adjusts the spray head rotation speed accordingly, creating a closed-loop control system that optimizes cleaning effectiveness while minimizing resource waste.
2Reliability
If the cleaning duration is prolonged to ensure adequate cleaning of heavily soiled portions, then cleaning effectiveness improves, but time and resource waste increases
Solution Approach 1:
The system applies different cleaning intensities to different portions of the tank based on local soiling conditions. Sensors detect varying levels of contamination across different areas, and the controller adjusts spray head rotation speed locally to match cleaning needs. This prevents uniform over-cleaning of already clean areas while ensuring adequate cleaning of heavily soiled portions.
Solution Approach 2:
The system dynamically changes the rotation speed parameter of the spray head based on real-time soiling detection. By varying this key parameter, the system optimizes cleaning effectiveness for each specific area and condition, avoiding both insufficient cleaning and unnecessary prolonged operation.
3Productivity
If the spray head rotation speed is increased to clean heavily soiled areas faster, then cleaning efficiency improves, but energy consumption and fluid waste increase
Solution Approach 1:
The spray head rotation speed is made dynamic rather than fixed. The system continuously adjusts rotation speed based on real-time soiling detection, using higher speeds only when and where needed for heavily soiled areas. This dynamic adjustment optimizes the balance between cleaning efficiency and energy consumption.
Solution Approach 2:
The system changes the rotation speed parameter in response to detected soiling conditions. By adjusting this parameter dynamically, the system achieves high productivity when necessary while minimizing energy consumption during lighter cleaning tasks, optimizing the overall energy-efficiency-productivity tradeoff.
