Angled Burner Nozzle Grid for Exhaust Gas Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas cleaning devices are inadequate in fully treating pollutants, including unburned fuels, leading to environmental pollution, and lack effective means to handle other contaminants, with suboptimal contact between gas and burner flames due to limited burner nozzle configurations.
Innovation Solution
A device with angled burner nozzles (0° to 80°) and a grid-shaped configuration of beam-like elements ensures comprehensive contact between gas and flames, using hydrogen and oxygen for oxidation, and optionally carbon dioxide for temperature control, to convert pollutants into harmless substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a straight bar or H-shape fuel manifold is used, then the device structure is simple, but the gas flow experiences large counterforce and does not contact the burner flames adequately
Solution Approach 1:
The fuel manifold is divided into multiple separate burner nozzles distributed across several beam-like elements arranged in a grid pattern, rather than using a single continuous bar or H-shape structure. This segmentation allows the gas flow to contact multiple flame sources simultaneously, improving cleaning efficiency while maintaining structural simplicity
Solution Approach 2:
The burner nozzles are arranged in a two-dimensional grid pattern across multiple beam-like elements, transitioning from a one-dimensional bar structure to a two-dimensional distribution. This dimensional change increases the contact area between the gas flow and flames, improving cleaning efficiency without significantly increasing device complexity
2Productivity
If mixing plates and deflector wings are added, then contact between gas and fuel is improved, but the device structure becomes more complex
Solution Approach 1:
The patent removes the mixing plates and deflector wings from the system entirely, achieving gas-flame contact through the distributed burner nozzles on beam-like elements alone. This extraction of unnecessary components simplifies the device structure while maintaining or improving cleaning efficiency
Solution Approach 2:
The beam-like elements with distributed burner nozzles inherently create the necessary gas-flame contact patterns through their geometric arrangement, eliminating the need for additional mixing or deflecting components. The structure serves its own mixing function through the natural flow patterns created by the grid arrangement
3Ease of manufacture
If burner nozzles are positioned at limited angles, then the device is easier to manufacture, but the mixing and cleaning optimization is insufficient
Solution Approach 1:
Different burner nozzles on the beam-like elements are positioned at different angles (0° to 80° relative to gas flow direction) to optimize local mixing and contact conditions. This local variation in nozzle angles improves overall cleaning efficiency while maintaining manufacturing feasibility through standardized angular positions
