Abstract
A gas cleaning apparatus is disclosed which comprises a housing having an inlet adjacent a bottom portion thereof and an outlet adjacent a top portion thereof. The housing preferably has at least one radially-extending vane disposed along a longitudinal axis of the housing. A settling tank is fluidly connected at a top portion thereof to the base of the housing, at least one outlet fluidly connected to a waste treatment apparatus, and at least one outlet fluidly connected to the housing between the inlet and the outlet of the housing. The waste treatment apparatus preferably has at least one outlet fluidly connected to the housing between the inlet and the outlet of the housing. Gas introduced into the inlet of the housing travels toward the outlet and encounters the at least one radially-extending vane which removes any large particles from the gas, and recycled fluid is introduced into the gas from the outlet of the settling tank and the outlet of the waste treatment apparatus to remove smaller particles therefrom.
