Abstract

A rotary adsorption/desorption gas treating apparatus includes a rotary drum rotatable along a rotation axis and having a plurality of gas passage compartments arranged in a peripheral direction of the drum. The apparatus further includes an adsorbing element cassette mounted inside each of the gas passage compartments and including a gas-permeable adsorbing mat. The rotational range of the rotary drum is divided between an adsorption zone and a desorption zone. In the adsorption zone, a treatment subject gas is allowed to pass the gas passage compartments in the direction along the rotation axis of the rotary drum. In the desorption zone, a refreshing gas is allowed to pass the gas passage compartments in the direction along the rotation axis of the rotary drum. The adsorbing mat, when mounted in the compartment, includes a portion thereof oriented normal or inclined relative to a side end face of the rotary drum.
