Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foul-gas treatment methods, such as adsorption using porous media, consume significant energy, water, and chemical reagents, generate waste, and are inefficient in terms of consumables and maintenance, while existing control systems lack proactive management to minimize odorous emissions effectively.
Innovation Solution
A foul-gas treatment device with a bypass system managed by a computerized control unit that uses forecasted and real-time pollutant concentration data to decide when to activate or bypass the treatment unit, optimizing energy use and reducing waste by treating odorous air only when dispersion is unfavorable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous treatment operation is implemented, then odor control effectiveness is improved, but energy consumption and operational costs increase
Solution Approach 1:
The treatment system dynamically adjusts its operation based on real-time meteorological conditions and odor concentration measurements. The system transitions between active treatment mode and bypass mode according to environmental factors such as wind speed, temperature, and humidity, which affect odor dispersion. This dynamic operation allows the system to maintain effective odor control during high-risk periods while reducing energy consumption during low-risk periods when natural dispersion conditions are favorable.
Solution Approach 2:
The system incorporates continuous feedback loops that monitor odor concentrations at multiple locations and compare them against threshold values. Measurement data from sensors positioned downwind from the emission source feeds back to the control unit, which automatically adjusts the treatment system operation. This feedback mechanism ensures that treatment is activated only when odor concentrations approach harmful levels, optimizing the balance between odor control effectiveness and energy consumption.
2Reliability
If treatment unit operates continuously, then odor emissions are controlled effectively, but consumables and maintenance requirements increase
Solution Approach 1:
Instead of continuous operation, the treatment system implements periodic action by operating only during specific periods when odor dispersion conditions are unfavorable. The system uses meteorological data to determine appropriate operating periods and switches to bypass mode during periods when natural dispersion is sufficient. This periodic operation significantly reduces consumable consumption (such as chemical reagents and filter media) and associated maintenance requirements while maintaining effective odor control during critical periods.
3Productivity
If proactive control based on forecasts is implemented, then operational efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements preliminary action by using forecasted meteorological data to predict future odor dispersion conditions before actual odor problems occur. The control unit receives forecast information about wind patterns, temperature trends, and humidity levels, and proactively adjusts treatment system operation in advance. This allows the system to prevent odor issues before they arise rather than reacting after problems occur, improving operational efficiency. The forecast data processing and predictive algorithms are integrated into the existing control architecture, managing complexity through structured data processing workflows.
4Object-affected harmful factors
If real-time monitoring and control are implemented, then odor impact is minimized, but measurement and detection requirements increase
Solution Approach 1:
The system uses meteorological parameters (wind speed, temperature, humidity) as intermediary factors to predict odor dispersion patterns. Instead of directly measuring odor concentrations at all possible locations and times, the system uses these intermediary meteorological data combined with emission source characteristics to model and forecast odor plume behavior. This intermediary approach simplifies the measurement and detection requirements while still achieving effective odor impact minimization through proactive control decisions based on the forecasted odor concentrations.

Function Achieved in This Case
This approach reduces operational expenses, equipment maintenance, and waste production while maintaining effective odor control by only using the treatment unit when necessary, ensuring better air quality and compliance with regulatory standards.
Implementation Method 1
The principle of treatment by adsorption is to cause the air stream that is to be treated to pass through a bed made up of an adsorbent medium in which the odorous molecules are captured
