It is a device that uses centrifugal force generated by rotating airflow to separate dust particles from gas. It features simple structure, small volume, cost-effective price, convenient operation and easy maintenance, with low power consumption, and is suitable for high-temperature gas. However, it is only suitable for collecting dust particles larger than 10μm, with relatively low collection efficiency for fine particles smaller than 5μm (dust collection efficiency is about 60%-90%). Therefore, it is usually used as the first-stage dust removal equipment in industrial dust treatment systems.

Simple and robust structure, no moving parts, reliable operation and low failure rate.
Small volume and compact layout, no need for complex auxiliary equipment, easy installation and maintenance.
Low power consumption and low operating cost, suitable for long-term continuous operation.
Good adaptability to high-temperature gas, can handle high-temperature flue gas up to 500℃ without cooling treatment.
Suitable for separating coarse dust particles, with high separation efficiency for particles larger than 10μm.
Cost-effective, with low one-time investment and long service life.
