Method for the purification of waste gas containing gaseous pollutants

摘要

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 a multiplicity of stepped trays and at the same time introducing an activated carbon into the top of the tower, allowing the waste gas and the activated carbon to come into contact to form a fluidized bed each on 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.
