我国松香工业中普遍采用列管换热器。列管为铜管,两头用铜花板固定。但是,铜对松香、松节油的耐腐蚀性能较差,常常造成松节油漏泄损失,铜的腐蚀会使产品带绿色而影响产品质量,铜花板铸造困难,质量很难保证。在雨季,我厂用水中泥沙很多,不易沉淀,冷凝器列管易结垢,甚至被泥沙堵塞,影响冷凝效果。我们参考兄弟厂的经验,结合我厂的具体情况,设计加工了一个螺旋板式冷凝器,用于连续蒸馏塔的中油冷凝,投产以来,运行正 China’s rosin industry commonly used tube heat exchanger. Tube for the brass, with two copper plate fixed. However, copper on rosin, turpentine corrosion resistance is poor, often resulting in turpentine leakage loss, the corrosion of copper products will lead to green and affect product quality, copper flower plate casting difficult, the quality is difficult to guarantee. In the rainy season, I plant a lot of sediment in water, not easy precipitation, condenser tube easy to scale, and even blocked by sediment, affecting the condensing effect. We refer to the experience of brothers plant, combined with the specific circumstances of our plant, designed and manufactured a spiral plate condenser for the continuous distillation tower of the oil condensate, put into operation, is
