ABSTRACT:
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.
