Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spray electrodes in electrostatic precipitators face challenges in effective cleaning due to their small surface area and parallel arrangement, which hinders the cleaning liquid's reach, leading to impaired performance over time.
Innovation Solution
The spray tips are designed with a base and tip sections, where the tip sections are inclined at an angle relative to the plane of the discharge electrode, allowing better access for cleaning jets and reducing the distance to collecting electrodes, enhancing ionization performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spray tips are arranged parallel to collecting electrodes, then the discharge electrode structure is simple, but the cleaning liquid cannot reach the spray tips effectively
Solution Approach 1:
The spray tips are inclined at an angle of 5° to 25° relative to the plane of the discharge electrode, transitioning from a purely parallel arrangement to a multi-dimensional configuration. This angular orientation allows the cleaning liquid to access the spray tip surfaces effectively while maintaining structural simplicity through integral formation from the metal strip.
2Reliability
If spray tips extend only in the plane of the discharge electrode, then the structure is simple, but the distance to collecting electrodes is larger reducing ionization performance
Solution Approach 1:
By inclining the spray tips at 5° to 25° relative to the discharge electrode plane, the tip sections protrude closer to the collecting electrodes, reducing the distance and strengthening the electric field for improved ionization performance.
Solution Approach 2:
The spray tips feature differentiated sections: base sections in the discharge electrode plane and inclined tip sections protruding toward collecting electrodes. This local geometric variation optimizes both cleaning accessibility and ionization effectiveness without requiring complete structural redesign.
3Ease of operation
If spray tips have small surface area, then the discharge electrode structure is compact, but the cleaning liquid cannot effectively remove buildup
Solution Approach 1:
The inclined tip sections create additional accessible surface area that is exposed to the cleaning liquid flow, allowing effective removal of particle buildup while maintaining a compact overall structure through the angular configuration rather than increasing linear dimensions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration improves cleaning efficiency and ionization performance by allowing better access for cleaning liquids and strengthening the electric field between the spray tips and collecting electrodes.
Implementation Method 1
A high-voltage field of, for example, 10 to 15 kV is applied between several adjacently arranged, usually plate-shaped collecting electrodes and discharge electrodes, as a result of which the particles, aerosols and gases contained in the gas flow are ionized at the discharge electrodes and then settle on the collecting electrodes.
Implementation Method 2
The inclined arrangement of the tip sections according to the invention also reduces the distance to the adjacent collecting electrodes in comparison to spray tips extending only in the plane, as a result of which a stronger electric field and a higher ionization performance can be achieved between the spray tips and the collecting electrodes.
