Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retort systems face challenges in minimizing the volume of processing fluid while maintaining a high flow rate, leading to significant fluid level gradients that result in energy inefficiencies and increased costs due to the need for continuous heating and cooling of a large volume of fluid.
Innovation Solution
A fluid suction system with an elongated manifold placed along the bottom of the retort vessel, which distributes the suction flow evenly along the length, reducing the number of suction points and minimizing fluid volume while preventing air entrainment and cavitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the volume of processing fluid is reduced, then energy consumption and fluid utilities are reduced, but the ability to maintain high flow rate through the retort outlet is compromised
Solution Approach 1:
The invention divides the single suction point into multiple suction points distributed along the bottom periphery of the retort. This segmentation allows the pump to draw fluid from multiple locations simultaneously, maintaining high flow rate capability while reducing the total volume of fluid required in the retort, thereby reducing energy consumption for heating and cooling.
2Loss of energy
If the fluid level is reduced to minimize volume, then energy consumption is reduced, but air or steam entrainment and pump cavitation occur
Solution Approach 1:
The multiple suction points are positioned at the same elevation around the periphery of the retort bottom, creating equipotential conditions for fluid suction. This ensures that fluid can be drawn uniformly from all points without creating localized low-pressure zones that would cause cavitation or allow air/steam entrainment, while still maintaining reduced overall fluid volume.
3Device complexity
If a single suction point is used, then the system is simple, but significant fluid level gradients develop causing inefficiencies
Solution Approach 1:
The suction system is segmented into multiple distributed suction points rather than a single central point. This segmentation eliminates the formation of significant fluid level gradients by allowing fluid to be drawn uniformly from multiple locations around the retort bottom, improving energy efficiency while adding only moderate complexity to the system.
