A spray drying system that shares a single spray drying device among multiple flue gas ducts, utilizing an exhaust gas introduction and discharge line configuration to evenly distribute high-temperature exhaust gas and manage flow rates, reducing the number of devices needed and simplifying the system's complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one spray drying device is provided for each flue gas duct, then each duct can be processed independently, but the number of devices increases leading to higher costs and reduced operational efficiency
Solution Approach 1:
The patent applies universality by designing a single spray drying device that can serve multiple flue gas ducts through shared exhaust gas introduction and discharge lines. This multi-functional configuration allows one device to perform the wastewater drying function for several ducts simultaneously, reducing the total number of devices while maintaining processing capability across all ducts.
Solution Approach 2:
The patent merges multiple exhaust gas introduction lines and discharge lines into a shared configuration that connects a single spray drying device to multiple flue gas ducts. By combining these flow paths, the system achieves the same functional result with fewer individual components, thereby reducing device complexity and operational costs.
2Reliability
If multiple spray drying devices are installed, then each duct has dedicated equipment, but operational and maintenance costs increase
Solution Approach 1:
The shared spray drying device is designed to handle wastewater from multiple flue gas ducts through a common configuration, making it a universal solution that eliminates the need for multiple dedicated devices. This reduces both operational costs (fewer devices to operate) and maintenance costs (fewer devices to maintain) while still providing reliable processing for each duct.
3Device complexity
If a shared spray drying device is used for multiple flue gas ducts, then device complexity is reduced, but exhaust gas flow distribution must be controlled
Solution Approach 1:
The patent incorporates flow rate control mechanisms that dynamically adjust exhaust gas distribution to the shared spray drying device from multiple flue gas ducts. This dynamic control system ensures that each duct's exhaust gas flow is properly regulated despite the shared configuration, maintaining operational ease while enabling the simplified single-device architecture.
4Ease of manufacture
If fewer spray drying devices are used, then installation and maintenance costs decrease, but the system must handle multiple ducts with a single device
Solution Approach 1:
The patent merges the exhaust gas introduction and discharge pathways from multiple flue gas ducts into a unified system that connects to a single spray drying device. This consolidation reduces installation costs (fewer devices to install) and maintenance costs (fewer devices to maintain) while the merged configuration manages the complexity of handling multiple ducts through a single integrated device.
