Explosion Relief Vent Layout for Compact, Clean Flame Arresters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion pressure relief devices, such as the Q-Rohr and Q-Box, require significant space due to large-volume flame arresters and are prone to contamination, which can impair their function.
Innovation Solution
The proposed explosion pressure relief device arranges the rupture disk behind the flame arrester, protecting it from external contamination and allowing for a more compact design. Additionally, the flame arrester can be shaped to increase its flow-through area, and a sound-absorbing insulating material can be integrated to enhance soundproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flame arrester is arranged in front of the rupture disk, then the flame arrester can be protected from external contamination, but the device requires more space and the flow-through area is reduced
Solution Approach 1:
The patent inverts the conventional arrangement by placing the rupture disk in front of the flame arrester instead of behind it. This inversion allows the flame arrester to be protected from external contamination by the rupture disk while enabling a more compact overall design with reduced volume requirements.
2Volume of moving object
If the flame arrester is arranged behind the rupture disk, then the device requires less space, but the flame arrester is exposed to external contamination
Solution Approach 1:
The rupture disk serves as an intermediary protective element between the external environment and the flame arrester. By positioning the rupture disk in front of the flame arrester, it acts as a barrier that prevents external contamination from reaching the flame arrester while still allowing the compact design to be maintained.
3Temperature
If the relief opening of the flame arrester is made larger, then the flow speeds of gases are reduced simplifying cooling and flame extinguishing, but the device requires more space
Solution Approach 1:
The inverted arrangement allows the flame arrester to be positioned closer to the rupture disk, enabling a larger effective flow-through area within a compact volume. The reduced distance between components compensates for the smaller overall device size while maintaining sufficient flow area for effective cooling and flame extinguishing.
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
This design minimizes space requirements and prevents external contamination of the flame arrester, while maintaining effective pressure relief and sound insulation, thus reducing production downtime and environmental noise pollution.
Implementation Method 1
the flow speeds of the gases through the flame arrester can be lower than the flow speeds in the area of the rupture disk, which simplifies the cooling of the hot gases and the extinguishing of the flames
Implementation Method 2
In the event of a pressure increase in the object or device to be protected, for example due to an explosion, the rupture disk opens and uncovers the opening through which gases can then escape
Implementation Method 3
a sound-absorbing insulating material can be integrated to enhance soundproofing
