介绍了一种导热油再生与热媒炉洗炉专利技术。将导热油再生与热媒炉洗炉穿插进行。利用移动式装置在生产现场将废导热油蒸馏,除去变质产物,输入生产系统洗炉,洗炉后的油再次蒸馏并降低酸值,输入生产系统即可。工艺和设备简单,洗炉加导热油再生可在一周内完成。不需额外投资,只要用1～2台热媒炉洗炉与换油费即可购置设备,10～20天完成换油,收回成本,还可获利。由于不另需洗炉剂,大大降低了成本。经350～370℃高温裂解对比试验、300℃较长时间高温老化对比试验、抗氧化性对比试验,并历时一年半在导热油最高许用温度300℃下模拟实际操作工况热运行实验,其结果证明再生导热油的质量可超过新油。
A patented technology for heat-conducting oil regeneration and heat-medium furnace washing was introduced. The HTF regeneration and heat medium furnace intervened. The use of mobile devices in the production site will waste heat oil distillation, removal of metamorphic products, enter the production system wash the furnace, wash the oil after the distillation and reduce the acid again, enter the production system can be. Process and equipment is simple, wash and heat oil regeneration can be completed within a week. No additional investment, as long as 1 to 2 heat exchanger furnace furnace and oil change costs to purchase equipment, 10 to 20 days to complete the oil change, the cost recovery, but also profitable. Because there is no need to wash the oven, greatly reducing costs. Comparison of high temperature cracking at 350 ~ 370 ℃, comparative test of aging at 300 ℃ for long time and contrast test of anti - oxidation, and simulating actual operation condition of hot running experiment for one year and a half under the maximum permissible temperature of HTF of 300 ℃, The results show that the quality of renewable heat transfer oil can exceed the new oil.
