Method for the purification of air or gas streams by a multi-path adsorption principle and moving-bed filtering apparatus for performing the method |
摘要 |
For the purification of air or gas streams the air or gas is conducted across a multi-zone adsorption apparatus through which a particulate filter material is moved downwardly by gravity. The gas stream is first admitted to the adsorption apparatus adjacent the downstream end to a first stage having an upstream and a downstream zone and, upon leaving the first stage, is divided into partial streams which are conducted back through an upstream adsorption material stage such that the gas from the most downstream filter material zone of the first stage which still has the highest contaminant content is admitted to and passed through the most upstream filter material zone of an upstream second stage of the apparatus and the upstream zone gas or air from the first stage is admitted to the downstream zone of the first stage in order to provide for high decontamination efficiency and for similar end decontamination of all the gas or air passed through the apparatus.
