Semi-buried Hazardous Material Storage with Vertical Firewalls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current storage facilities for hazardous materials are inadequate, particularly at production and consumption sites, and during transit, as they often lack proper authorization and safety measures, leading to risks of ignition, environmental pollution, and uncontrolled fires or explosions.
Innovation Solution
A semi-buried storage facility with buried cells and elevated enclosures, featuring fire-resistant construction, a motorized handling gantry, and advanced ventilation systems to prevent the spread of fires and explosions, while ensuring safe handling and containment of hazardous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hazardous materials are stored in conventional facilities, then storage capacity is provided, but safety against ignition and fire spread is insufficient
Solution Approach 1:
The storage facility is divided into multiple separate cells (at least three cells) arranged side by side, each cell being delimited by vertical firewalls. This segmentation isolates hazardous materials of different categories and prevents fire spread between storage areas, directly addressing the ignition risk and fire spread problem while maintaining storage capacity.
Solution Approach 2:
Vertical firewalls are introduced as intermediary structures between cells and between the storage area and the external environment. These firewalls act as mediators that block fire propagation paths, preventing harmful factors from spreading while allowing controlled access for loading and unloading operations.
2Ease of manufacture
If modular warehouses are used for hazardous materials storage, then construction flexibility is improved, but safety measures for certain hazardous materials are not met
Solution Approach 1:
The facility uses separate cells delimited by firewalls rather than a single modular structure. This segmentation allows each cell to be designed and constructed according to specific safety requirements for different hazardous materials, achieving both construction flexibility and compliance with safety measures.
Solution Approach 2:
Different cells can be designed with specific local characteristics suited to the particular hazardous materials they store. The vertical firewalls and enclosure structures provide localized safety measures that can be tailored to the specific requirements of different material categories, ensuring compliance while maintaining overall construction flexibility.
3Productivity
If containers are parked at multimodal logistics platforms, then transport efficiency is improved, but authorization and safety management become difficult
Solution Approach 1:
The facility is designed to receive and store containers from multiple transport modes (road, rail, river) through a common infrastructure with vertical firewalls and enclosed cells. This universal design allows efficient handling of containers from different sources while maintaining unified safety management and authorization controls, resolving the contradiction between transport efficiency and safety management.
4Quantity of substance
If cells are arranged side by side in the longitudinal direction, then storage capacity is increased, but fire spread between cells may be facilitated
Solution Approach 1:
Vertical firewalls are installed as delimitating structures between adjacent cells in the longitudinal direction. These firewalls physically separate the cells while allowing the facility to maintain high storage capacity through the arrangement of multiple cells side by side, preventing fire spread while preserving storage capacity.
Solution Approach 2:
The vertical firewalls act as intermediary barriers between cells, blocking fire propagation paths while allowing the cells to be arranged in close proximity for maximum storage capacity. These firewalls mediate between the conflicting requirements of high storage capacity and fire prevention.
