제품 설명
Equipment Introduction & Technical Parameters
1. Equipment Type & Application
For the above four types of solid waste, the mainstream equipment includes submerged arc furnace (mineral heat furnace), DC melting furnace, rotary hearth furnace + electric furnace combination line, which achieve both harmless disposal and resource recovery.
| Solid Waste | Recommended Equipment | Main Purpose | Typical Process |
|---|---|---|---|
| Fly Ash | DC Melting Furnace / Closed Submerged Arc Furnace | Solidify heavy metals, decompose dioxins, separate molten salt | Melting at 1400–1500℃ → Salt recovery → Slag solidification |
| Aluminum Powder / Aluminum Ash | Submerged Arc Furnace / Aluminum Melting Furnace | Recover metallic aluminum, remove impurities | High-temperature melting → Aluminum settling → Reuse |
| Red Mud | RHF + Melting Separation Furnace | Recover iron, produce hot metal, utilize slag | Pelletizing → Prereduction → Melting separation |
| Coal Gangue | Submerged Arc Furnace / Electric-assisted Kiln | Make bricks, ceramsite, waste heat power generation | Briquetting → Sintering → Densification |
2. General Process & Structure
- Raw Material Preparation: Crushing & grinding → Batching & pelletizing → Drying.
- Main System: Furnace body (steel shell + refractory lining) → Electrode system → Power supply system → Water cooling & flue gas cleaning.
- Key Reaction: High-temperature reduction/melting → Slag-iron separation → Tapping → Waste heat recovery.
3. Typical Technical Parameters
3.1 Electrical Parameters (General)
| Parameter | Range | Remarks |
|---|---|---|
| Transformer Capacity | 6,300 – 40,500 kVA | Higher for red mud/fly ash |
| Secondary Voltage | 80 – 290 V | Low voltage, high current |
| Secondary Current | 20,000 – 80,000 A | Three-phase balanced |
| Power Factor | ≥ 0.9 | With reactive power compensation |
3.2 Furnace & Electrode Parameters (33,000 kVA)
| Parameter | Value |
|---|---|
| Furnace Shell Diameter | 10 – 12 m |
| Furnace Chamber Diameter | 7 – 9 m |
| Lining Thickness | 300 – 500 mm |
| Electrodes | 3 pieces, Φ1.2 – 1.5 m |
| Furnace Top Temperature | 900 – 1100℃ |
3.3 Process & Consumption Indexes
| Material | Melting Temp | Daily Capacity | Power Consumption | Key Index |
|---|---|---|---|---|
| Fly Ash | 1400–1500℃ | 50–200 t/d | 2,400–3,200 kWh/t | Heavy metal leaching standard; dioxin decomposition ≥99.9% |
| Aluminum Ash | 1200–1400℃ | 80–300 t/d | 1,800–2,500 kWh/t | Al recovery ≥98% |
| Red Mud | 1450–1650℃ | 100–300 t/d | 2,800–3,800 kWh/t | Metallization rate ≥90% |
| Coal Gangue | 1050–1300℃ | 200–500 t/d | 35–100 kWh/t | High strength brick/ceramsite |
4. Advantages
- Strong adaptability: Handles various solid wastes.
- Environmentally friendly: High temperature decomposes dioxins, stabilizes heavy metals.
- Resource recovery: Recovers Fe/Al, produces building materials.
- High automation: PLC control for temperature, electrode, feeding.
5. Selection Suggestion
- Small scale (<100 t/d): 6,300–12,500 kVA
- Medium (100–300 t/d): 12,500–25,000 kVA
- Large (>300 t/d): 25,000–40,500 kVA
Closed DC furnace is preferred for fly ash for strict emission standards.
6. Typical Applications
- Red Mud Project: 33,000 kVA submerged arc furnace, 200 t/d, hot metal + slag for rock wool.
- Fly Ash Melting: DC furnace, salt recovery ≥95%, slag for road base.
- Coal Gangue Utilization: Bricks + waste heat power generation.
