Gas Dedusting by Slotted Filter
A new deduster is proposed, in which a slotted filter screen with perforated frame wire wound in several layers is used to collect dust, with specific sizes of slots between the coils and layers of wire. The filter is equipped with an efficient regeneration system and can be used to clean hot, aggressive gases, as well as abrasive dust. A stationary filtration method on various dusts with high (98-99% or more) or target cleaning efficiency and acceptable wall friction is developed and studied. The calculation method, which enables cleaning simulations and determination of optimal performance parameters and dimensions of the slotted filter structure, is presented.
