Equipment Description:
I. Working Principle
1. Airflow rotation and dust separation: The dust-laden gas enters the cylinder tangentially to form an external vortex, and the dust particles are thrown to the wall of the device under the action of centrifugal force, and slide down the wall to the ash hopper.
The purified gas forms an internal vortex and is discharged from the exhaust pipe. The particle separation efficiency is positively correlated with the gas rotation speed.
2. Centrifugal force: The centrifugal force can reach 5-2500 times the gravity, which is significantly higher than the gravity settling chamber, but the capture efficiency of fine particles <5μm drops sharply.
II. Performance characteristics
| Advantages | Limitations |
| Simple structure, no moving parts, low maintenance cost | Low efficiency for fine particles (<5μm), requires bag filter |
| High temperature resistance (≤400℃), can handle high concentration dust | Prone to clogging when handling sticky/humid dust |
| Wide range of air volume (2000-50,000m³/h) | High pressure loss (500-2000Pa) |
3. Technical parameters
Applicable particle size: 5-200μm, multi-tube parallel structure can be increased to 3μm particles (efficiency 80-85%).
Handling air volume: single tube 2000-50,000m³/h, multi-tube parallel structure can reach 100,000m³/h.
Temperature/pressure resistance: conventional carbon steel structure temperature resistance ≤400℃, ceramic lining type temperature resistance 1000℃, pressure resistance 500kPa.
4. Application scenarios
Industrial field: cement plant raw material mill, steel plant blast furnace gas pre-dust removal.
Grain processing (wheat, corn crushing) coarse particle collection.
Special working conditions: high temperature flue gas: with ceramic lining or heat-resistant steel material.
Corrosive gas: stainless steel or fiberglass material.
V. Maintenance and Optimization
Regular maintenance: Check the ash hopper discharge every shift to prevent ash accumulation and blockage; check the inner wall wear of the cylinder every month. Efficiency improvement: The inlet wind speed is controlled at 12-20m/s (too high increases pressure loss, too low reduces separation efficiency). Multi-stage cyclone dust collectors are connected in series or combined with wet dust removal and bag dust removal to form a multi-stage system
Main structures and components:
1. Inlet pipe
Structure and function: adopt tangential or axial design to guide dust-laden gas into the cylinder in a tangential direction to form a rotating airflow.
Tangential inlet can enhance centrifugal force and improve the separation efficiency of large particles.
2. Cylinder and cone
Cylinder: cylindrical structure, which is the main area of airflow rotation and dust separation, where dust-laden gas forms an external vortex.
Cone: connected to the bottom of the cylinder, gradually reducing the cross-section, accelerating airflow rotation and guiding dust to sink to the ash discharge port.
The cone angle is usually 20-30°, which affects the dust settling efficiency.
3. Exhaust pipe
Position and function: located in the center of the cylinder, used to discharge purified gas, its diameter is usually 0.3-0.5 times the diameter of the cylinder.
The end of the exhaust pipe may extend to the outside of the cylinder to prevent secondary dust.
4. Ash discharge device
Ash hopper and ash discharge port: The ash discharge port is set at the bottom of the cone to collect the separated dust. Some equipment is equipped with a lock valve (such as a star-shaped ash discharge valve) to prevent air leakage.
The tilted design of the ash hopper (≥60°) promotes the sliding of dust and avoids blockage.
5. Special structure (some models)
Double-cylinder/multi-cylinder design: Some models (such as double-cylinder cyclone dust collectors) use inner and outer cylinder structures to enhance centrifugal force and improve small particle capture efficiency.
Auxiliary guide device: Some equipment adds a guide plate in the air inlet pipe or cylinder to optimize airflow distribution.
6. Technical parameters
| Components | Functions and Features |
| Diameter of cylinder | Directly affects the air volume, the larger the diameter, the stronger the processing capacity |
| Inlet gas velocity | Usually 12-20m/s, too high will increase the pressure loss |
| Applicable particle size | Mainly captures particles ≥5μm, with an efficiency of 70-95% |
7. Simplified structural diagram
The dust-laden gas enters the cylinder from the tangential air inlet pipe, forming an external vortex.
The dust particles are thrown toward the wall of the device by centrifugal force and slide to the bottom of the cone.
The purified gas forms an internal vortex and is discharged through the exhaust pipe, and the dust is centrally processed through the ash discharge port.
Through the synergistic effect of the above structures, the cyclone dust collector can efficiently separate large dust particles and is suitable for pre-dust removal in industrial scenarios such as cement, metallurgy, and grain processing.
