Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sulfur granulation processes require multiple passes and additional equipment like size-segregating screens and return conveyors, leading to a large machinery footprint and inefficiencies.
Innovation Solution
A dual-chamber header design with separate internal piping structures for sulfur and water streams, allowing for distinct flow rates and pressures at different nozzle sets, enabling simultaneous seed generation and granule enlargement in a single pass, eliminating the need for screening and return conveyors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional single-chamber header design is used, then the structure is simpler, but it cannot provide distinct flow rates and pressures to different nozzle sets, requiring multiple passes and additional equipment
Solution Approach 1:
The header is divided into multiple chambers (first chamber, second chamber, third chamber) with separate internal piping structures. Each chamber can independently control flow rate and pressure to different nozzle sets, enabling simultaneous seed generation and granule enlargement operations with optimized parameters for each function.
Solution Approach 2:
Different chambers of the header are designed to provide locally optimized conditions for specific functions. The first chamber provides conditions for seed generation, while the second and third chambers provide conditions for granule enlargement, allowing each region of the header to have the specific flow rate and pressure characteristics needed for its purpose.
2Manufacturing precision
If multiple passes with screening and return conveyors are used, then granule size control is improved, but the machinery footprint increases
Solution Approach 1:
The header design combines multiple functions (seed generation, granule enlargement, size control) into a single integrated system. By providing distinct flow rates and pressures to different nozzle sets through separate chambers, the system achieves precise granule size control without requiring separate screening and return conveyor equipment.
Solution Approach 2:
The multi-chamber header serves multiple functions simultaneously: it generates seeds, enlarges granules, and controls final granule size all within a single device. This multi-functional design eliminates the need for additional specialized equipment while maintaining precise size control.
3Adaptability or versatility
If separate internal piping structures are implemented, then distinct flow rates and pressures can be provided to different nozzles, but the header design becomes more complex
Solution Approach 1:
The internal piping is segmented into separate chambers and lines (first internal pipe, second internal pipe, third internal pipe) that can be independently controlled. This segmentation provides the flexibility to adjust flow rates and pressures for different nozzle sets while organizing the complexity into manageable, modular sections.
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 design achieves efficient sulfur granule production with a reduced machinery footprint, enhancing production efficiency and reducing space requirements.
Implementation Method 1
a sulfur header assembly having two internal piping structures within an external pipe casing for delivering separate molten sulfur liquid streams to different sets of nozzles
Implementation Method 2
water is simultaneously streamed to the curtain of particles cascading downwardly through the contact zone. The water streams inside the drum constantly cool the sulfur granules
Implementation Method 3
the molten sulfur solidifies in the form of solid globules or prills
Implementation Method 4
The hot temperature inside the drum (in excess of 100° C.) is due to the heat emitted from the sulfur granules. This heat vaporizes the water droplets and exits the drum through exhaust fans
