The invention relates to an ammonia gas drying system for a liquid ammonia mercerizing machine. The ammonia gas drying system comprises a plurality of upper ammonia gas heating systems and lower ammonia gas heating systems arranged in a drying tank in a staggered mode in the fabric conveying direction. The drying tank is provided with high-temperature ammonia gas inlets and exhaust openings for exhausting heated ammonia gas. Each ammonia gas heating system comprises a high-temperature ammonia gas conveying channel, an adjusting screw rod, an adjusting beam and a breathable plate. The adjusting beams are arranged between the breathable plates and supporting hoods of the high-temperature ammonia gas conveying channels. The upper sides and the lower sides of the adjusting beams make seal contact with the breathable plates and the supporting hoods. The adjusting screw rods in all the ammonia gas heating systems conduct synchronous transmission through synchronous belts. The interval distance between the adjusting beams is adjusted through the adjusting screw rods so that the ventilation portions of the breathable plates can be matched with the size of the fabric for heating so as to form a heating area adjusting structure. The ammonia gas drying system has the advantages that the heating range can be adjusted according to the size of the fabric, the utilization rate of ammonia is increased, and the cost is reduced.
