摘要:
A rotary gas recovery system which comprises a fixed adsorption tower which is divided into a plurality of sections arranged in the circumferential direction around the center axis and filled with adsorbent, a first manifold for supplying and discharging gases on the side of the fixed adsorption tower, a second manifold for supplying and discharging gases on the side of pipe, and a rotatable valve plate which is interposed between the first manifold and the second manifold and sequentially connects the first manifold to the second manifold by a constant motion.
