A pre-cyclone dust collector is a device that utilizes centrifugal force to separate dust from gas, often serving as a pretreatment unit for dust removal systems.  

- Structural Composition**: It mainly consists of a tangential inlet, cylinder, cone, exhaust pipe, and dust hopper. Dust-laden gas enters through the tangential inlet, where the cylinder acts as the outer vortex dust separation zone. The cone accelerates dust settlement, purified gas exits through the top exhaust pipe, and separated dust collects in the hopper.  

- Working Principle**: Dust-laden gas enters the cyclone separator through the inlet pipe, forming a high-speed rotating outer vortex along the cylinder wall. Dust is thrown toward the wall by centrifugal force, loses kinetic energy upon collision, and falls into the hopper under gravity. Purified gas forms an inner vortex and exits through the top exhaust pipe.  

- Performance Characteristics**: Simple structure, no moving parts, low maintenance costs, high air handling capacity, and resistance to high temperatures, humidity, and corrosive gases. It achieves over 90% removal efficiency for coarse dust but only 30%-60% for particles smaller than 5μm, requiring combination with other equipment.  

- Applications**: Widely used in mining crushing, building material production, mechanical processing, boiler flue gas treatment, etc., as a pre-treatment device for bag filters or electrostatic precipitators to remove large particles and reduce the load on subsequent fine dust removal equipment.  

- Customized separators in various specifications and styles can be produced according to client requirements.
