METHOD FOR THE PURIFICATION OF WASTE GAS CONTAINING GASEOUS POLLUTANTS

摘要

METHOD FOR THE PURIFICATION OF WASTE GAS CONTAINING GASEOUS POLLUTANTS In a process for the purification treatment of a waste gas containing gaseous pollutants, including the steps of upwardly introducing the waste gas into the bottom of a tower with a multiplicity of stepped trays and at the same time introducing an activated carbon into the top of the tower, and contacting the waste gas with the activated carbon to form a fluidized bed on each of the stepped trays thereby causing the gaseous pollutants in the waste gas to be adsorbed on the activated carbon, the waste gas can be continuously purified by recycling the activated carbon spheres and adopting, as the stepped trays, perforated plates of a specific design.
