The invention discloses a long-man-hour closed circulating breathing system which comprises a box body provided with a breathing pipeline; the circulating breathing device is fixed in the box body and comprises a first lung bag connected with one end of the breathing pipeline, a second lung bag connected with the other end of the breathing pipeline and an adsorbent tank connected with the first lung bag and the second lung bag. The adsorbent tank is used for adsorbing carbon dioxide in exhaled gas; the mixed oxygen supply device comprises an oxygen tank filled with oxygen, a diluted gas tank filled with mixed gas and an automatic gas adding valve connected with the oxygen tank and the diluted gas tank respectively, and the automatic gas adding valve is connected with the first lung bag. By the adoption of the design, oxygen can be recycled, long-time deep diving can be achieved during use, and cost is saved.
