Aeration Flow Channel Structure for Low-Loss Upwelling Diffusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing aerator design experiences significant loss in water flow velocity due to the impact force exerted by upwelling water flow on the suspended carrier, limiting the diffusion and oxygenation range of the aerator.
Innovation Solution
The aeration device incorporates a carrier with first and second buffer members forming an arc-shaped flow channel, a draft tube with water inlets and outlets, and an aeration assembly to guide oxygenated water flow, reducing velocity loss and enhancing diffusion through arc-shaped and guide flow channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the upwelling water flow directly impacts the suspended carrier to achieve oxygenation, then the oxygenation function is achieved, but the water flow velocity is significantly reduced due to impact force
Solution Approach 1:
The patent employs an arc-shaped flow channel instead of a direct linear path. The upwelling water flow enters the arc-shaped channel and is guided along a curved trajectory before diffusing into the water body. This curvature allows the flow to change direction smoothly without directly impacting the carrier, thereby maintaining higher flow velocity while still achieving effective oxygenation through the extended diffusion path.
2Device complexity
If the water flow rate is reduced due to impact loss, then the diffusion range of water flow is reduced, but the carrier structure remains simple
Solution Approach 1:
The arc-shaped flow channel extends the diffusion path of the water flow by utilizing a curved geometry. This allows the water to travel a longer distance and cover a larger area before dissipating, thereby increasing the diffusion range without requiring a more complex carrier structure. The curved path maximizes the coverage area within the same structural footprint.
3Productivity
If the upwelling water flow directly diffuses around through water outlets, then the oxygenation process is completed, but the diffusion range is limited due to velocity loss
Solution Approach 1:
The arc-shaped flow channel guides the upwelling water flow along a curved path that extends beyond the immediate vicinity of the carrier. This curved trajectory allows the oxygenated water to diffuse over a larger area and reach more distant regions of the water body, thereby expanding the oxygenation range while ensuring complete oxygenation through the extended contact path.
