Removable Nozzle Assembly for Gas Transfer Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas transfer devices in wastewater treatment and other applications are often bulky and fixed, making them difficult to inspect, clean, or replace, leading to fouling and inefficiencies due to the use of intermediate pipes that cause head loss and hinder maintenance.
Innovation Solution
A gas transfer system with removable nozzle assemblies that can be easily attached and detached from a monolithic manifold system, eliminating the need for intermediate pipes and allowing for more efficient cleaning and maintenance, featuring a gas manifold, a liquid manifold, and removable nozzle assemblies with a cap for fluid-tight connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If intermediate pipes are used to connect gas transfer devices to distribution piping, then the devices can be delivered from generic piping, but the system becomes bulky and creates additional head loss and fouling opportunities
Solution Approach 1:
The gas transfer device is merged with the distribution piping by fabricating the piping integrally with the gas transfer device, eliminating intermediate pipes and reducing system bulkiness while maintaining compatibility
Solution Approach 2:
The integrated design provides multi-functionality by combining gas transfer and distribution functions in a single unit, eliminating the need for separate intermediate piping components
2Reliability
If gas transfer devices are fixed to piping systems, then stable operation is achieved, but the devices cannot be readily removed for inspection, cleaning or replacement
Solution Approach 1:
The gas transfer device is segmented into a removable nozzle assembly that can be detached from the distribution piping, allowing maintenance while maintaining stable operation during use
Solution Approach 2:
The connection between the gas transfer device and piping is made dynamic through a removable coupling mechanism, transitioning from fixed during operation to removable during maintenance
3Adaptability or versatility
If feed pipes are used to deliver liquid and gas, then delivery from generic piping is enabled, but additional head loss and fouling opportunities are created
Solution Approach 1:
The feed pipes are merged with the gas transfer device by integral fabrication, eliminating separate intermediate piping that causes head loss while maintaining compatibility with generic distribution piping
4Adaptability or versatility
If intermediate pipes and feed pipes are used, then connection to generic distribution piping is achieved, but additional fouling opportunities are created
Solution Approach 1:
The intermediate pipes and feed pipes are merged into the gas transfer device structure, eliminating separate piping components that create fouling opportunities while maintaining connection capability
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 a more robust, efficient, and maintainable gas transfer solution with reduced fouling and installation time, enabling superior gas and liquid distribution and allowing for upgrades based on material or process advancements.
Implementation Method 1
The liquid spray coming from a nozzle in the ejector creates a pressure drop due to the Bernoulli effect. This pressure drop can be used to move gas through the ejector.
