Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dust binding technologies face inefficiencies in reliably binding dust over large areas with minimal dust binding agents, high wear, and potential dust escape, especially in turbulent environments like mining and construction sites.
Innovation Solution
A device comprising a binder reservoir with a pressurized binder line and atomizing nozzles positioned away from dust sources to create an artificial mist or drizzle, utilizing a gas cushion pressure vessel to manage pressure and reduce wear, and elastic pipes for flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If atomizing nozzles are positioned close to dust sources, then dust binding effectiveness is improved, but the system becomes vulnerable to turbulent airflow that prevents mist settlement
Solution Approach 1:
The patent introduces a calm air zone as an intermediary space between the dust source and the nozzle. The nozzle is positioned in this calm air zone rather than directly at the dust source, allowing the mist to settle effectively without being disrupted by turbulent airflow from the dust generation point.
Solution Approach 2:
The patent shifts the nozzle positioning from a direct one-dimensional approach at the dust source to a spatial arrangement that utilizes the three-dimensional calm air zone surrounding the dust source, enabling mist to settle in a stable environmental dimension.
2Area of stationary object
If high pressure is used to generate mist, then dust binding coverage is improved, but component wear and pressure surges increase
Solution Approach 1:
The patent installs a gas cushion (inert gas or air) in the pressure vessel beforehand to cushion and absorb pressure surges generated during high-pressure mist generation. This pre-configured cushioning mechanism protects components from wear caused by pressure fluctuations while maintaining the high pressure needed for effective dust binding coverage.
3Reliability
If continuous spraying is used, then dust binding reliability is improved, but binder consumption increases
Solution Approach 1:
The patent employs periodic spraying cycles rather than continuous operation. The system sprays mist during specific periods when dust is generated, then pauses, allowing the mist to settle and reducing overall binder consumption while maintaining dust binding reliability through targeted intermittent application.
