Purification method and equipment for filtering gas by using liquid medium
InactiveCN100493668CCushion the shockReduce wearUsing liquid separation agentPurification methodsLiquid medium
A liquid medium filtering method for cleaning gas includes such steps as introducing the raw gas to inside of external cylindrical casing via gas inlet tube, flowing through guide cone to impact the lower liquid medium while mixing the raw gas with the splashed liquid to become slurry, passing through fining cover, generating a dynamic liquid medium filter layer on a perforated fining plate while dividing the raw gas into innumerable fine gas columns, passing through the perforated plate for filtering and washing, and de-moistening.
