Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric precipitators require high voltage and large power supplies, leading to increased electric power consumption and difficulty in reducing their width for space-efficient installation due to the need for significant spacing between discharge and ground electrodes.
Innovation Solution
The electric precipitator design incorporates high and low voltage electrodes made of non-conductive film parts with conductive fiber electrode layers, allowing for discharge generation at lower voltages and reduced width, with the high voltage electrode serving both charging and dust collection functions, and the low voltage electrode acting as a ground, enabling compact installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high voltage is applied to the discharge electrode to generate discharge between electric wire and ground electrode, then pollutant charging and collection function is achieved, but electric power consumption increases and device width cannot be reduced below certain level
Solution Approach 1:
The high voltage electrode is segmented into multiple electrode layers (first electrode layer for charging part, second electrode layer for dust collection part) arranged at different positions. This segmentation allows different sections to perform different functions (charging and collection) simultaneously, enabling the discharge electrode to serve dual purposes and reducing the need for separate charging and collection sections, thereby reducing overall device width and power consumption.
Solution Approach 2:
The high voltage electrode structure is designed to perform multiple functions: the first electrode layer charges pollutants while the second electrode layer collects charged dust particles. This multi-functionality eliminates the need for separate charging and collection electrodes, reducing the number of components and overall device width while maintaining effective pollutant removal and reducing power consumption.
2Reliability
If high voltage is applied to the discharge electrode, then discharge between electrode and ground electrode is generated for pollutant collection, but device width increases due to required safety spacing
Solution Approach 1:
The electrode structure employs a nested configuration where the first electrode layer and second electrode layer are positioned at different depths within the same spatial envelope. The first electrode layer is exposed through through-holes in the film parts while the second electrode layer is positioned between the film parts, creating a nested arrangement that maximizes functional density within minimal width.
Solution Approach 2:
The patent transitions from a conventional planar electrode arrangement to a three-dimensional layered structure. By positioning electrode layers at different depths and exposing them through through-holes in film parts, the design utilizes the third dimension (depth/layering) to accommodate multiple functions within a compact width, effectively moving the solution from two-dimensional to three-dimensional space utilization.
3Reliability
If conventional double-stage type structure with separate charging part and dust collection part is used, then pollutant precipitation function is achieved, but device complexity and width increase
Solution Approach 1:
The patent merges the charging function and dust collection function into a single integrated high voltage electrode structure. The first electrode layer performs charging while the second electrode layer performs dust collection, combining what were previously separate functions into one unified component. This merging reduces device complexity by eliminating the need for separate charging and collection electrode assemblies while maintaining effective pollutant removal.

AI summary
An electrode precipitator having a high voltage electrode and a low voltage electrode arranged apart from each other at a desired interval. The high voltage electrode includes a charging part which is positioned upstream of an air flow direction to charge a pollutant, and a dust collection part which is spaced from the charging part and positioned downstream of the air flow direction to precipitate the charged pollutant therein.
