POY (pre-oriented yarn) oil agent online recycling system and application thereof in environment-friendly oil-saving DTY (draw textured yarn) production

The invention discloses a POY oil agent online recycling system and application thereof in environment-friendly and oil-saving DTY production, the system comprises an improved hot box, a negative pressure collecting device, an oil agent intermediate storage tank and an oil agent pump, all the parts are connected through sealing oil pipes, and a recycled oil agent and a texturing oil agent are reasonably compounded for DTY oiling; the equipment is simple and reliable, the POY oil agent in the elasticizing hot box is recycled, on one hand, the production cost is reduced, the oil agent consumption is reduced, on the other hand, the oil smoke discharge amount is reduced, and the equipment is healthy and environmentally friendly; in addition, due to the fact that a large amount of oil smoke is adsorbed, the box heating period is greatly prolonged, the equipment maintenance frequency is reduced, and the production cost is further optimized. 本发明公开了一种POY油剂在线回收利用系统及其在环保节油型DTY生产中的应用，该系统包括改进型热箱、负压收集装置、油剂中间储罐、油剂泵，各部件间通过密
