Solution Overview
Problem
Existing electrostatic precipitators face issues with vibration and short circuits between discharge and collection electrodes, and inefficient management of washing water, leading to reduced collection efficiency and potential environmental pollution.
Innovation Solution
The electrostatic precipitator apparatus includes a housing with a collection module, discharge electrodes, and a washing water treatment device featuring an adsorption belt, rollers, and a scraper to manage washing water and separate dust, while maintaining the distance between electrodes to prevent short circuits and optimize washing water usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the distance between discharge electrode and collection electrode is decreased, then collection efficiency is improved, but short circuit risk increases
Solution Approach 1:
An insulating support structure is introduced as an intermediary between the discharge electrode and collection electrode. This mediator maintains the necessary electrical isolation while allowing the electrodes to be positioned at an optimal small distance for high collection efficiency, thus resolving the contradiction between improved productivity and reduced reliability risk.
2Ease of operation
If washing water is immediately discharged, then operational simplicity is maintained, but environmental pollution occurs
Solution Approach 1:
Instead of immediately discarding the washing water, the system recovers it by collecting and storing it in a reservoir for subsequent reuse. This approach eliminates environmental pollution while maintaining operational simplicity through an automated collection and storage system.
3Productivity
If corona discharge voltage is increased, then dust collection efficiency is improved, but electrode vibration increases
Solution Approach 1:
A damping support structure with elastic elements is introduced to provide counteracting forces against the vibration generated by corona discharge. This allows the system to operate at high voltages for improved dust collection efficiency while the damping structure absorbs and mitigates the resulting electrode vibrations.
