Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet scrubber systems face issues with countercurrents due to different suction pressures from various combustion engines, leading to inefficient pollutant removal and increased costs when handling exhaust gases from multiple engines.
Innovation Solution
The exhaust gas discharge device employs a funnel system with cleaning water spray nozzles and agitating blades in each exhaust pipe to prevent countercurrents and enhance mixing, allowing for effective pollutant removal without the need for a wet scrubber, thereby reducing installation costs and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a wet scrubber is installed to remove pollutants from exhaust gases, then pollutant removal effectiveness is improved, but installation cost and space requirements increase
Solution Approach 1:
The invention divides the exhaust gas treatment system into multiple separate exhaust pipes, each equipped with its own cleaning water spray nozzle and agitating blades. This segmentation allows each pipe to be treated independently, preventing countercurrents while maintaining effective pollutant removal without requiring a large centralized wet scrubber system.
Solution Approach 2:
Cleaning water is introduced as an intermediary substance to remove pollutants from exhaust gases. The cleaning water spray nozzles deliver water into each exhaust pipe, and the agitating blades enhance the interaction between the cleaning water and exhaust gases, enabling effective pollutant removal through a simpler system than a traditional wet scrubber.
2Area of stationary object
If multiple exhaust gases from different combustion engines are supplied to a single scrubber, then space utilization is improved, but countercurrents occur due to different suction pressures leading to inefficient operation
Solution Approach 1:
Instead of consolidating all exhaust gases into a single scrubber, the invention segments the system by providing separate exhaust pipes for different combustion engines. Each pipe maintains its own pressure characteristics, preventing countercurrents while still achieving centralized pollutant removal through coordinated cleaning water spray application.
Solution Approach 2:
The invention applies local quality by equipping each exhaust pipe with its own cleaning water spray nozzle and agitating blades. This allows each pipe to be optimized for its specific suction pressure conditions, ensuring efficient pollutant removal in each local zone without the negative effects of mixing exhaust gases with different pressure characteristics.
3Device complexity
If cleaning water is supplied to a single centralized location, then system complexity is reduced, but countercurrents from multiple exhaust pipes cannot be prevented
Solution Approach 1:
The cleaning water supply system is segmented to provide separate spray nozzles in each exhaust pipe. This segmentation allows the system to maintain relative simplicity while effectively addressing the different pressure conditions in each pipe, preventing countercurrents and ensuring smooth operation.
Solution Approach 2:
By providing cleaning water spray nozzles and agitating blades in each exhaust pipe, the system applies local quality to match the specific operational conditions of each pipe. This ensures that each pipe receives appropriate treatment for its unique suction pressure characteristics, preventing countercurrents while maintaining overall system simplicity.
