It should be noted that: by "primary and secondary separation principles", in conjunction with fig. 1, we mean that when dust-laden gas (i.e. cloudy dust) travels tangentially to the cylindrical housing 5 and enters the interior of the cylindrical housing 5, the gas makes a rotational motion within the cylindrical housing 5, entraining large-particle dust or impurities or a dense air stream, which travels on the outside and forms an air stream a; the spiral air inlet flow is arranged at the position close to the center of the cylindrical shell 5 and is an inner spiral exhaust air flow B with low density or basically clean; the spiral exhaust flow is the airflow A formed by forcing the gas to move towards the conical shell 6 along the cylindrical shell 5 when the gas of the airflow A continuously gushes along the cylindrical shell 5; the helical inlet flow runs down under air pressure to an outlet flow C which contains a dust flow of small amounts of gas. However, the substantially clean inner helical exhaust flow B will spiral upwardly and be discharged through the exhaust pipe 7. This principle is similar to that of washing machine laundry spin-dry water, which is easily thrown outwards and swept away when the peripheral speed is sufficiently fast (so water can be understood as dust and other dense particles, the more pronounced the centrifugal effect at the highest speed is).
