Ventilation Features for Vacuum Waste Chutes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum waste collection systems face challenges in managing odors and pathogens due to the stagnation of materials and air in chutes and loading stations, which increases the risk of contamination and odor buildup.
Innovation Solution
Incorporating ventilation features such as apertures or vent tubes that create a negative pressure differential between the storage chamber and the transport pipe, allowing for the passive or assisted flow of contaminated air away from the loading station and chute, preventing the buildup of odors and pathogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the size of chute or holding time of materials is increased to enhance transport capacity, then the system can handle larger volumes of waste, but odors and pathogen risks increase due to material stagnation
Solution Approach 1:
The patent extracts and removes contaminated air and odors from the chute environment through dedicated ventilation openings and air extraction systems, separating the harmful air phase from the material storage function, thereby allowing larger chute sizes without proportional increases in odor and pathogen risks
Solution Approach 2:
The patent introduces air movers and ventilation systems as intermediary devices that actively manage air quality within the chute, mediating between the material storage function and the harmful air stagnation, enabling enhanced transport capacity while controlling odors and pathogens
2Object-affected harmful factors
If ventilation openings are added to chutes and loading stations to improve air quality, then odors and pathogens are reduced, but system complexity increases
Solution Approach 1:
The patent employs passive ventilation openings that utilize natural pressure differentials and air buoyancy to achieve air exchange without requiring complex active control systems, allowing the system to self-regulate air quality through strategically positioned openings
Solution Approach 2:
The patent applies pneumatic principles by utilizing pressure differentials and air flow dynamics to drive ventilation, employing air movers that leverage fluid mechanics to remove contaminated air through controlled openings, reducing complexity compared to mechanically complex ventilation systems
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
This solution effectively reduces the transmission of pathogens and minimizes odors within the system by continuously drawing contaminated air from the loading station and chute into the transport pipe, maintaining air quality and safety.
Implementation Method 1
A vent tube is provided that conveys fluid from a loading station to a transport pipe. The vent tube is operable to convey fluid from the loading station to the transport pipe even when a door of the loading station is in a closed position. The transport pipe is provided with a negative pressure to draw fluid into the transport pipe through the vent tube.
Implementation Method 2
The ventilation feature of the system including the tube or conduit is operable to transfer or convey fluid (e.g. air) to the transport pipe due to a negative pressure differential between the storage chamber and the transport pipe.
