Electric Precipitator Electrode Support Structure

Solution Overview

Problem

Electric precipitators with high voltage electrodes made of film members and electrode layers suffer from low strength, leading to sagging and contact with low voltage electrodes when extended, making them unsuitable for larger designs.

Innovation Solution

Incorporating support members made of insulating materials to maintain separation between high and low voltage electrodes, preventing sagging and allowing for higher voltage applications without breakdown.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the high voltage electrode is extended to a designated size or more, then the dust collection area is increased, but the electrode may sag and contact the low voltage electrode due to low strength

Engineering Contradiction:

Improvedust collection areaVSAvoidelectrode strength

Core Design Contradiction:

Area of stationary objectVSStrength

Solution Approach 1:

The support structure is divided into multiple support members distributed along the high voltage electrode. Each support member provides localized support to prevent sagging in specific sections, allowing the electrode to be extended while maintaining structural integrity and preventing contact with the low voltage electrode.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Support members made of insulating material are introduced as intermediary elements between the high voltage electrode and the low voltage electrode. These support members provide mechanical support to prevent sagging while maintaining electrical insulation, thus allowing extended electrode length without risk of contact or breakdown.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Volume of moving object

If the high voltage electrode is made thinner to minimize thickness, then the compact structure is improved, but the strength decreases making it prone to sagging
