Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air filtration systems in livestock buildings, particularly poultry farms, face challenges with dust accumulation in heat recovery devices, leading to increased maintenance time and electricity consumption due to the lack of efficient dust filtration mechanisms.
Innovation Solution
A mobile dust filter system with a suction nozzle that allows for continuous or interval cleaning without disassembly, integrated into the ventilation installation, which can be easily moved and cleaned using motorized means, reducing maintenance time and maximizing dust capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dust filter is installed in the heat recovery device, then dust capture is improved, but maintenance time increases due to regular cleaning requirements
Solution Approach 1:
The filter element is made movable rather than fixed, allowing it to be repositioned between a filtering position (covering the air outlet) and a cleaning position (exposed to the suction nozzle). This dynamic configuration enables the filter to be cleaned in place without dismantling the entire heat recovery device, thereby reducing maintenance time while maintaining effective dust capture during operation
Solution Approach 2:
The system incorporates an automated cleaning mechanism where a suction nozzle automatically removes accumulated dust from the filter element when positioned adjacent to it. This self-service capability reduces the manual labor and time required for maintenance, as the filter can be cleaned quickly by moving it to the cleaning position rather than requiring full device disassembly
2Object-affected harmful factors
If a dust filter is installed in the heat recovery device, then dust capture is improved, but electricity consumption increases due to higher air passage resistance
Solution Approach 1:
The movable filter element can be easily repositioned to optimize its configuration. When cleaned, it can be placed in the cleaning position away from the air flow path, minimizing resistance to air passage. During operation, it is positioned to cover the air outlet for effective filtration. This dynamic positioning allows the system to maintain low air resistance when the filter is clean, reducing electricity consumption by the extraction fan
3Area of stationary object
If multiple heat recovery devices are installed, then ventilation coverage is improved, but total maintenance time is multiplied
Solution Approach 1:
Each heat recovery device is equipped with a movable filter element that can be independently repositioned for cleaning. This allows maintenance personnel to quickly access and clean filters in multiple devices without requiring full disassembly of each unit, significantly reducing the cumulative maintenance time across multiple devices while maintaining broad ventilation coverage
Solution Approach 2:
The automated suction cleaning capability allows each filter to be cleaned quickly and efficiently without extensive manual intervention. When multiple devices are installed, this self-service cleaning mechanism can be applied to each unit independently, preventing maintenance time from being multiplied across devices as it would with traditional dismantling and cleaning procedures
