Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flameless venting systems face challenges in mounting directly onto curved surfaces, are cumbersome to install, and difficult to inspect and maintain, particularly in industries requiring cleanliness and accessibility, such as the food and pharmaceutical sectors.
Innovation Solution
A flameless venting system with a curved mounting flange that allows direct attachment to curved vessels, features a rear hatch for inspection without removing the quenching module, and includes a sensor for automatic notification of explosion vent opening, enhancing ease of installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flameless venting system uses a flat mounting flange, then the system can be manufactured with standard components, but it cannot mount directly to curved vessel surfaces requiring additional adapters
Solution Approach 1:
The mounting flange is designed with a curved surface that matches the curvature of cylindrical vessels, allowing direct mounting without adapters. This curvature adaptation enables the system to interface seamlessly with curved surfaces while maintaining a simple single-piece flange structure.
2Reliability
If the quenching module is permanently fixed to the explosion vent, then the system provides continuous protection, but it becomes difficult to inspect and maintain
Solution Approach 1:
The system is divided into separable components: the quenching module, explosion vent, and mounting flange. The quenching module can be removed from the explosion vent through a release mechanism, allowing inspection and maintenance of individual components while maintaining continuous protection when assembled.
Solution Approach 2:
The connection between the quenching module and explosion vent is designed to be dynamic rather than static, using a releasable fastening mechanism that allows the quenching module to be easily attached and detached for maintenance while providing secure continuous protection during operation.
3Shape
If the explosion vent is positioned on curved vessel surfaces, then it integrates with the vessel geometry, but it becomes difficult to access for inspection and maintenance
Solution Approach 1:
By segmenting the system into removable components (quenching module, explosion vent, flange), the design allows the explosion vent to be positioned on curved surfaces for geometric integration while enabling easy access for maintenance by removing the quenching module first.
Solution Approach 2:
The mounting flange acts as an intermediary component that bridges the curved vessel surface and the explosion vent assembly. This intermediate structure allows the explosion vent to be positioned optimally on curved surfaces while providing a accessible interface for maintenance operations.
4Difficulty of detecting and measuring
If the system requires removal of the quenching module for inspection, then the explosion vent can be accessed, but it increases maintenance time and complexity
Solution Approach 1:
The system is segmented into removable components where the quenching module can be detached from the explosion vent through a simple release mechanism, allowing inspection of the explosion vent without complex disassembly procedures and reducing maintenance time.
Solution Approach 2:
The quenching module is designed as a separable component that can be extracted from the explosion vent assembly for independent inspection or replacement, allowing the explosion vent to be accessed efficiently without removing the entire assembly.
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 system provides convenient installation on curved surfaces, reduces contamination risks, and facilitates easy inspection and maintenance, while effectively mitigating explosions by absorbing flames and pressure waves.
Implementation Method 1
the heat is absorbed by the filter material and the combustion process is momentarily starved of oxygen
Implementation Method 2
Combustion within the enclosure may create an increased pressure (i.e., overpressure), which in turn can lead to opening of the explosion vent
Implementation Method 3
the combustion process is momentarily starved of oxygen
