Retrofit EP

Strengthened Electric Field

• High-voltage power supply upgrade: Replaces the existing power supply with one that delivers higher voltage and current, and adds pulse energization to improve particle collection
• Discharge electrode upgrade: Replaces existing electrodes with new designs that charge particles more effectively (e.g., high-efficiency discharge electrodes)

Mechanical Improvements

• Collecting electrode replacement: Uses electrodes with larger surface area and improved contact
• Rapping system upgrade: Improves dust removal from the plates with upgraded mechanical or electromagnetic rapping

Flow Optimization

• Gas flow redesign: Improves gas distribution to achieve uniform airflow and higher overall collection efficiency

Expanded Collection Area

• Additional modules: Installs extra collection zones in the ESP to increase capacity
• Inlet/outlet design changes: Improves inlet and outlet gas flow for more efficient operation

Hybrid Technology Application

Combines the ESP with other dust collection technologies (e.g., bag filters or scrubbers) to create a hybrid system
Adds a wet ESP stage to remove fine particles and water-soluble pollutants

Cost Efficiency

Lower cost and shorter construction time than a new system, with maximum reuse of existing structures

Performance Enhancement

Raises collection efficiency to over 99%, depending on unit condition
Captures PM10 and PM2.5

Longer Equipment Life

Extends the service life of existing ESPs

Regulatory Compliance

Helps existing units meet stricter emission standards
