A post-dyeing drying and sizing system for yarns as in claim 1, wherein: an annular baffle (721) is welded in the middle of the inner wall of the discharge nozzle (72), a slot (722) is formed in the surface of the annular baffle (721), an active carbon filter screen (723) is movably arranged at the upper end of the annular baffle (721), a plug rod (724) is fixedly arranged at the lower end of the active carbon filter screen (723), and the plug rod (724) is matched with the slot (722).

10. A process for drying and shaping a post-dyeing yarn drying and shaping system according to any one of claims 1 to 9, wherein: the method comprises the following steps:

s1: after the yarn is dyed in the dyeing pool (1), the yarn is conveyed by a conveying roller (11), and then the yarn is conveyed into a drying box (2) through a material guide opening (3) and a guide roller (4) for drying treatment;

s2: the interior of the drying box (2) is divided into a first cold air chamber (21), a hot air chamber (22) and a second cold air chamber (23), so that the yarn can be subjected to air cooling preliminary dehydration, then is heated and dried, and finally is subjected to air cooling and cooling operation treatment;

s3: when the yarn is subjected to preliminary air-cooling dehydration and enters the hot air chamber (22) for drying treatment, accumulated water on the surface of the yarn is evaporated to generate hot steam during drying, and the suction fan (62) can rotate to generate negative pressure to adsorb the hot steam in the hot air chamber (22);

s4: the hot steam absorbed into the gas cylinder (6) is conveyed into the condensation pipe (71) through the gas pipe (7) to be condensed, so that the hot steam is changed into water again and finally discharged into the dye printing pool (1);

s5: when the yarn is dehydrated and cooled in the first cold air chamber (21) and the second cold air chamber (23), the water blown off on the yarn falls into the water collecting plate (5) through the water leakage holes (24) to be collected.
