Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric precipitators face challenges in increasing precipitation efficiency due to the interference of the electric field from the precipitating part with the electric charging part, leading to hindered ion generation and dust charging, which affects overall precipitation performance.
Innovation Solution
The electric precipitator design includes an electric charging part receiving a first high voltage and a precipitating part with first and second precipitating plates, where the first plate receives a low voltage and the second plate receives a higher voltage, with the electric charging part spaced farther from the second precipitating plate than the first, minimizing electric field interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electric charging part and precipitating part are positioned adjacent to each other in limited space, then the device can be miniaturized, but the electric field of the precipitating part interferes with the electric charging part, deteriorating electric charging performance
Solution Approach 1:
The precipitating part is divided into multiple precipitating plates (first precipitating plate and second precipitating plate) with different voltage applications. The first precipitating plate is positioned closer to the electric charging part while the second precipitating plate is positioned farther away, creating segmented zones that reduce electric field interference while maintaining compact device size.
Solution Approach 2:
Different regions of the precipitating part are assigned different functions and voltage levels. The first precipitating plate receives a first voltage while the second precipitating plate receives a second voltage, creating local quality differences that optimize both charging performance and precipitation efficiency within the limited space.
2Volume of moving object
If the electric charging part and precipitating part are positioned adjacent to each other, then the device can be miniaturized, but the surface of the high-pressure side precipitating plate becomes electrically charged, adversely affecting the electric charging part
Solution Approach 1:
The harmful electrical charge accumulation on the precipitating plate surface is addressed by introducing a second precipitating plate at a farther distance from the electric charging part. This extraction approach separates the high-voltage precipitating region from the charging region, preventing charge accumulation interference while maintaining miniaturization.
Solution Approach 2:
The first precipitating plate acts as an intermediary element between the electric charging part and the second precipitating plate. It receives the first voltage and creates a gradual voltage transition, preventing direct high-voltage interference with the charging part while still enabling effective dust precipitation.
3Productivity
If the electric field of the precipitating part is strong to improve precipitation efficiency, then dust particles are effectively precipitated, but ion generation in the electric charging part is hindered
Solution Approach 1:
The precipitating part is segmented into multiple plates with different voltage levels. The first precipitating plate operates at a lower voltage to minimize interference with ion generation, while the second precipitating plate operates at a higher voltage to maximize precipitation efficiency, thus resolving the contradiction between these two functions.
Solution Approach 2:
The solution moves from a single-dimensional precipitating plate to a multi-dimensional arrangement with multiple plates at different distances from the charging part. This dimensional change allows simultaneous optimization of ion generation (closer plate) and precipitation efficiency (farther plate) without mutual interference.
