Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling systems for metallurgical vessels, such as electric arc furnaces, face inefficiencies in cooling high-temperature regions due to the upward direction of coolant spray opposing gravitational drainage, leading to increased coolant depth and retained heat, reducing cooling capacity.
Innovation Solution
A cooling system that utilizes the kinetic energy of the coolant to direct spent coolant towards a collection manifold, positioning distribution dispensers to spray coolant at an obtuse angle away from high heat regions, minimizing buildup and maximizing heat transfer by relocating coolant flow away from thermally stressed areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If coolant is sprayed upward towards high heat regions, then cooling capacity is improved, but spent coolant accumulates and retains heat, reducing cooling efficiency
Solution Approach 1:
The patent inverts the conventional cooling approach by directing coolant spray away from high heat regions rather than toward them. The distribution dispensers are positioned to spray coolant in a direction that uses kinetic energy to carry spent coolant away from thermally stressed areas, preventing heat retention and accumulation while still achieving effective cooling of the metallurgical vessel surface.
2Quantity of substance
If coolant depth increases in high heat regions, then heat absorption is enhanced, but cooling capacity is reduced due to retained heat
Solution Approach 1:
The patent extracts the spent coolant from the high heat regions by directing the spray away from these areas. The kinetic energy of the coolant flow carries the spent coolant away from thermally stressed areas, preventing accumulation and heat retention, while maintaining sufficient coolant presence for effective heat absorption and continuous cooling capacity.
3Force
If distribution dispensers are positioned to spray coolant towards high heat regions, then heat transfer is maximized, but spent coolant buildup occurs
Solution Approach 1:
The patent inverts the conventional approach by positioning distribution dispensers to spray coolant away from high heat regions rather than toward them. This inversion uses the kinetic energy of the coolant to prevent spent coolant buildup in thermally stressed areas while maintaining effective heat transfer through the metallurgical vessel surface.
