Marine Drum Vent Gas Discharge System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pipeline systems in marine vessels discharge vent gas at low speed and pressure, leading to accumulation around the vent post, potentially creating explosive atmospheres.
Innovation Solution
A pipeline system that increases the temperature and pressure of vent gas within a drum before discharge, using a gas pipeline valve to direct the high-kinetic-energy gas away from the vent post, and includes a control system to manage valve operations based on pressure sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drum interior is always open to the atmosphere through the gas pipeline and vent post, then the air pressure in the drum remains at atmospheric pressure, but the vent gas has low temperature and pressure resulting in low discharge speed and potential accumulation around the vent post
Solution Approach 1:
The gas pipeline valve is opened in advance before vent gas discharge to build up pressure in the drum, creating high-pressure vent gas that discharges at high speed. This preliminary pressure buildup action resolves the contradiction by ensuring both safety (through high-speed discharge) and reliability (through controlled pressure management).
Solution Approach 2:
The system transitions from a static open-state to a dynamic controlled-state where the gas pipeline valve regulates pressure. The drum interior pressure is dynamically adjusted from atmospheric pressure to high pressure, enabling the vent gas to discharge at high speed and prevent accumulation around the vent post, thus resolving the speed-safety contradiction.
2Productivity
If the gas pipeline valve is opened to discharge vent gas, then the vent gas can be discharged from the vent post, but the drum interior is exposed to the external environment
Solution Approach 1:
The gas pipeline valve serves as an intermediary component that controls the connection between the drum interior and the external environment. By opening the valve only when necessary for vent gas discharge and closing it otherwise, the system achieves high discharge efficiency while preventing harmful external exposure to the drum interior, thus resolving the productivity-harmful factors contradiction.
Solution Approach 2:
The gas pipeline valve operates periodically - opened only during vent gas discharge events and closed during normal operation. This periodic action ensures that the drum interior remains isolated from the external environment during most of the time, while still enabling efficient vent gas discharge when needed, resolving the contradiction between discharge efficiency and environmental protection.
