Battery Rack Spray Pipe Layout for Fast Multi-Point Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing systems for energy storage systems struggle to effectively suppress high-pressure fires in battery cells due to increased flame and ejection pressure, necessitating a more efficient method to quickly deliver fire extinguishing agents to multiple fire points.
Innovation Solution
A fire extinguishing device comprising a storage box, supplier, distributer, and spray pipes that efficiently distribute fire extinguishing agents to battery modules, utilizing sensors and controllers to adjust flow rates based on fire detection, allowing one-way or two-way distribution depending on the fire's extent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general fire suppression equipment is used, then the system is simple and cost-effective, but it cannot effectively suppress high-pressure fires in battery cells with increased flame and ejection pressure
Solution Approach 1:
The fire suppression system is divided into multiple independent spray pipes, each equipped with spray nozzles positioned at different locations within the battery rack. This segmentation allows targeted suppression at multiple fire points simultaneously, improving effectiveness against high-pressure battery fires while maintaining modular simplicity
Solution Approach 2:
The system transitions from traditional ceiling-mounted or side-mounted spray arrangements to a three-dimensional network of spray pipes positioned within the battery rack structure. This spatial distribution enables fire extinguishing agent delivery from multiple directions and heights, effectively countering high ejection pressure flames from battery cells
2Speed
If fire extinguishing agent is supplied from a single location, then the system structure is simple, but it takes longer to reach multiple fire points
Solution Approach 1:
The distribution system is segmented into multiple supply pipes branching from a central storage box to different regions of the battery rack. Each supply pipe connects to spray pipes at various heights and positions, enabling simultaneous agent delivery to multiple fire points and reducing overall response time
Solution Approach 2:
The system provides localized fire suppression capability at different positions within the battery rack through strategically positioned spray pipes. Each location has optimized spray nozzle placement and agent delivery capacity tailored to local fire risk and battery module arrangement, ensuring rapid effectiveness at each fire point
3Adaptability or versatility
If spray pipes are positioned at fixed locations, then the system is easy to install and maintain, but it cannot adapt to fires at various heights and positions
Solution Approach 1:
The spray system is divided into multiple independent spray pipes positioned at different heights and locations within the battery rack. Each spray pipe serves a specific zone, providing comprehensive coverage for fires at various positions while maintaining standardized modular installation for ease of assembly and maintenance
Solution Approach 2:
The system extends fire suppression coverage from traditional two-dimensional ceiling or wall mounting to a three-dimensional arrangement of spray pipes distributed throughout the battery rack volume. This vertical and horizontal distribution adapts to fires at any height or position while using standardized components for straightforward installation
