Three-Direction Nozzle Lance for Exhaust Gas Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzle lances for exhaust gas treatment in combustion plants are not optimized for efficient pollutant removal, particularly with increasing regulatory requirements for lower pollutant limits.
Innovation Solution
A nozzle lance with a nozzle head featuring three nozzles, where two nozzles have main discharge directions in a common plane and the third nozzle has an oblique discharge direction, is used for atomizing an active fluid using pressurized gas. This design increases the treated zone and ensures optimal atomization and distribution of the active fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional nozzle lance with single or dual nozzles is used, then the device complexity is low, but the treated zone is insufficient for efficient pollutant removal
Solution Approach 1:
The nozzle head is segmented into three separate nozzles (first, second, and third nozzles) with different discharge directions. Each nozzle is responsible for treating a specific zone within the exhaust gas chamber, collectively covering a larger treated volume than a single nozzle could achieve.
Solution Approach 2:
The third nozzle is arranged with its main discharge direction oblique to the plane containing the first and second nozzles, adding a spatial dimension to the treatment coverage. This three-dimensional arrangement of nozzles expands the treated zone in multiple directions within the exhaust gas chamber.
2Manufacturing precision
If the nozzle lance uses multiple nozzles with different discharge directions, then the atomization distribution is optimized, but the device complexity increases
Solution Approach 1:
Each nozzle is designed with a specific discharge direction tailored to its functional requirement. The first and second nozzles discharge in a common plane, while the third nozzle discharges obliquely to this plane, creating locally optimized atomization patterns in different spatial zones of the exhaust gas chamber.
3Productivity
If a larger treated zone is achieved through multiple nozzles, then pollutant removal efficiency improves, but the device complexity increases
Solution Approach 1:
The nozzle head is divided into three independent nozzles, each contributing to the overall pollutant removal efficiency by treating different zones. This segmentation allows parallel treatment of multiple exhaust gas streams simultaneously, enhancing total productivity.
Solution Approach 2:
By arranging nozzles in three-dimensional space with oblique discharge directions, the system treats a larger volume of exhaust gas concurrently, directly improving pollutant removal efficiency through expanded spatial coverage.
