摘要

Cleaning waste air from a livestock mast assembly comprises adding a pre-coat material, e.g. coke dust, lime dust and/or hydrated lime dust to the sucked off air, depositing over a filter, collecting the final product below the filter, removing by a simple device and utilizing. The predominant parts of the filter unit are continuously pre-coated and only a small amount of the pre-coat is found in the dedusting. Preferred Features: More than 99% of the whole filter units are continuously pre-coated and only 1% of pre-coat is found in the dedusting.
