Hi-Filter improves the control performance to fine dust and particles by the technical combination of the electric precipitation & filtration.
1. The Performance of the Hi-filter
- Total collection efficiency:99.99%.
- Dust concentration at exit:1mg/Sm3.
- Detachment Interval:200 minutes.
- Filtering speed :3.6 m/minute.
- Life time of filter bag:48 months.
- Effectiveness for the removal of fine dust particles above 99.9% for below-1 micron particles.
2. The Key Technology
- Structure design technology for low pressure dop and uniform distribution of exhaust gases and dust particles.
- Design technology of optimum structure for reduction of dust loading.
- Design technology of compartment structure for treatment of optimum flow rate.
- Development of the highly durable surface-filtering dust collection
- Filter for anti-dischargeable ions.
3. Problems of Existing Hybrid System
- Complicated structure-difficult maintenance and repair damage of bag filters due to the high voltage discharge-impossible operation.
- Reattachment of detached dust-low efficiency of dust collections and detachment.
- Contamination of discharge electrode due to dust particles-decreases in particle charging and collection efficiency.
