Abstract

本发明属于PA66原液生产技术领域，且公开了一种PA66原液生产用冷却设备，包括原液罐，所述原液罐的外侧面固定套接有换热罐，所述换热罐的外侧面设有控制组件，所述换热罐的上下两端与控制组件之间活动卡接，所述换热罐的顶端设有位于换热罐上方的冷却水预处理罐，所述换热罐的底端设有位于换热罐下方的冷却水降温罐。本发明通过在换热罐的上下两端分别设置有冷却水预处理罐和冷却水降温罐，分别对应低温的冷却水和高温的冷却水，同时通过控制组件的设置，使得当冷却水经过换热后导致温度过高时，可通过控制组件的作用，自动排出温度较高的冷却水，避免传统装置再进行长时间冷却时，容易发生积热的问题，提高冷却效果。
