A gas treating apparatus including a treating flow passage having a first opening and a second opening through which the gas passes to be treated; a pair of ducts for transporting the treatment-target gas or an element-refreshing gas through the treating flow passage positioned between a third opening and a fourth opening; and a rotary frame for radially supporting the treating flow passage and unidirectionally rotatable relative to the pair of ducts. At the upper and lower sides in the rotational direction of the third and fourth openings, there are provided first sealing members. As these sealing members come into sliding contact with at least one of the sealing faces at the upper and lower sides and at the sides of the first opening and of the second opening, the members provide gas sealing effect between the treating flow passage and the pair of ducts positioned between the third and fourth openings and in the vicinity of the same.

Gas treating apparatus

A gas treating apparatus for removing solvent from a treatment-object gas. The apparatus has an adsorbing member formed mainly of activated carbon capable of adsorbing the solvent. The adsorbed solvent trapped on the adsorbing member is desorbed therefrom when the member is moved by a conveying device to a desorbing section where a high-temperature recycling air is supplied. When a functional trouble occurs with the apparatus, the adsorbing member currently located adjacent the desorbing section is effectively evacuated from a high-temperature-zero-air-flow condition thereby avoiding an abnormal temperature rise and a successive fire accident apt to occur in the desorbing section vicinity due to an oxidation reaction of the adsorbed solvent. Consequently, the invention provides the apparatus with superior safety.
