Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid aeration systems, such as surface aerators, blower/diffuser systems, and rotor aerators, face limitations in aeration depth, multidirectionality, and energy efficiency, leading to inadequate dissolved oxygen distribution and 'dead zones' in treatment processes.
Innovation Solution
A swing-type submersible floating aerator comprising a gas-ring compressor, base, pipe, support tube, swing device, and driving device, which allows 360-degree rotation and multidirectional aeration through a propeller assembly and rotary lobed duct, enabling deep and wide aeration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If surface aerators pump water upward to create aeration, then dissolved oxygen content increases, but energy consumption increases due to high horsepower requirements
Solution Approach 1:
The aerator employs a swing device that enables the aerator assembly to rotate 360 degrees horizontally, transforming the fixed-direction aeration into multidirectional aeration. This dynamic rotation allows water to be pumped in various directions rather than solely upward, reducing the energy required to overcome gravity while maintaining effective aeration coverage throughout the water body.
Solution Approach 2:
The invention introduces horizontal rotation capability to the traditional vertical aeration approach. By adding the horizontal dimension through the swing device, the system achieves three-dimensional aeration coverage without requiring proportional increases in vertical pumping power, thereby improving energy efficiency while expanding aeration depth and coverage.
2Quantity of substance
If rotor aerators throw liquid into the air for aeration, then dissolved oxygen content increases, but malodors are released through aerosol formation
Solution Approach 1:
The system uses a gas-ring compressor to generate compressed air that is delivered through a pipe directly to the propeller assembly underwater. This pneumatic approach creates aeration through gas injection and water circulation rather than mechanical throwing of liquid into the air, eliminating aerosol formation and associated malodor release while maintaining effective oxygen transfer to the water.
3Device complexity
If conventional aerators operate in fixed direction, then结构简单 (simple structure), but aeration depth and multidirectionality are limited creating dead zones
Solution Approach 1:
The swing device incorporates a swing bearing with inner and outer rings that enable the aerator assembly to rotate freely in a horizontal plane. This dynamic rotation mechanism allows the aerator to change its operating direction continuously, achieving 360-degree coverage and eliminating dead zones while maintaining relatively simple mechanical construction through the use of standard bearing components.
