Aquatic Capping System with Cyclone Dust Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aquatic capping systems fail to uniformly distribute capping materials on water bodies, leading to thicker layers and the release of dust and particulates into the atmosphere.
Innovation Solution
A system comprising an enclosure with a spreader, cyclone, and hopper, which controls the distribution of capping material and captures dust and particulates by separating gases and solids, ensuring a uniform layer and minimizing atmospheric release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional aquatic capping systems discharge material directly into water, then the system is simple to operate, but the distribution of capping material is non-uniform and dust/particulates are released into the atmosphere
Solution Approach 1:
The system divides the capping material discharge process into separate functional components: a enclosure to contain the material, a spreader to distribute it uniformly, and a cyclone separator to remove dust. This segmentation allows each component to perform its specific function efficiently, achieving uniform distribution while controlling dust emissions.
Solution Approach 2:
The patent introduces an enclosure as an intermediary structure between the capping material source and the water body. This enclosure contains the material during discharge, allows for controlled spreading, and prevents direct uncontrolled discharge. The cyclone separator acts as another intermediary to remove dust particles from the air stream before material is deposited.
2Reliability
If a thicker layer of capping material is deposited to ensure sufficient barrier, then the barrier reliability is improved, but the amount of material required and the environmental impact increase
Solution Approach 1:
The system provides visual feedback during the capping process by allowing observation of material distribution through the enclosure. This enables operators to monitor and adjust the spreading process in real-time to achieve uniform thickness, ensuring the minimum required barrier effectiveness while avoiding excessive material application.
Solution Approach 2:
The patent changes the distribution parameters of the capping material by using a controlled spreading mechanism rather than direct discharge. The spreader distributes material at controlled rates and angles, achieving uniform thin layers that meet barrier requirements without the need for thicker applications.
3Ease of operation
If dry or substantially dry capping material is discharged, then the material can be easily transported and stored, but dust and particulates are released into the surrounding atmosphere
Solution Approach 1:
The system extracts harmful dust and particulates from the air stream using a cyclone separator. The cyclone removes these contaminants before the air is discharged from the enclosure, allowing dry capping material to be handled easily while preventing dust emissions. The separated dust can be collected and reused, further reducing material waste.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves a highly uniform thickness of capping material and effectively captures dust and particulates, preventing their release into the atmosphere, thus enhancing environmental protection and remediation efficiency.
Implementation Method 1
The cyclone separates gases (mostly air) and dust from solid materials
Implementation Method 2
The spreader, preferably a rotating plate spreader, distributes the capping material through the open bottom end of the enclosure in an even and controlled manner
Data Source
AI summary
A system for the controlled distribution of capping material and the capture of dust and particulates includes an enclosure having a top wall and a continuous perimetrical side wall with an open bottom end. A cyclone inside the enclosure separates the air, dust, and particulates from solid materials. The air, dust, and particulates are exhausted from the enclosure to a filtering system. The solid capping material passes from the cyclone to a hopper and then to a spreader for the controlled distribution of the capping material through the open bottom end of the enclosure.
