Abstract:
1. A revolving gas adsorption concentrator, comprising: a honeycomb shaped rotor that rotates and supports an adsorbent, the honeycomb shape rotor having a seal that divides the honeycomb shape rotor into at least a desorption zone and an adsorption zone, wherein the seal comprises an elastic seal and a heat-resistant seal, the elastic seal touches a surface of the honeycomb shaped rotor, the heat-resistant seal is formed of a material whose heatproof temperature is higher than that of the elastic seal, the heat-resistant seal includes two or more seal members with opened spacing therebetween to form a labyrinth, and to prevent hot gas from going to the elastic seal, each heat-resistant seal member comprising a plate and an elastic member adjacent to the plate, a gap being maintained between the plate and the surface of the honeycomb shaped rotor, and the elastic seal is provided outside the desorption zone with respect to the heat-resistant seal.
