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.
