Cyclone separation zone is confined by closed diffuser and confuser elements with their concave side surfaces. Note here that projection of side surface of both said elements features common radius. Aeromix flow in separation zone is subjected to effects of constant magnetic fields arranged discretely along side surfaces of said elements. Under said effects, magnetically susceptible particles are displaced along inner surface of said elements and removed for storing. Aeromix magnetically susceptible particles in confuser element separation zone are displaced in cyclone axial space and shifted by gravity on carrier to be transferred to store. Aeromix in separation zone is subjected to effects of upward airflow to separate dusty particles therefrom and forced in cyclone discharge pipe. |
