沥青液位的测量,是我厂沥青生产中的老大难问题。在我厂原釜式氧化沥青装置中,氧化釜是间断操作,釜内的操作条件是:液相温度:270℃,操作压力:1.2Kg/cm~2绝压,釜高10米,仅釜顶,底各装一支热电偶指示最高,最低液位。但由于长期运行热电偶保护套管上结焦,测量滞后大,运行不可靠,不能满足生产上的要求,长期采用人工检尺的方法,劳动强度大,操作麻烦,工人直接接触高温油气劳动条件差。去年年初,我厂在实现沥青塔式连续氧化
Measurement of asphalt level, asphalt plant in our factory is the crux of the problem. In our factory, the autoclave is operated intermittently. The operation conditions in the autoclave are: liquid temperature: 270 ℃, operating pressure: 1.2Kg / cm ~ 2 absolute pressure, kettle height 10m, kettle top only At the end of each installed a thermocouple indicates the highest and lowest level. However, due to long-term operation thermocouple protection casing coking, measurement lag, running unreliable, can not meet the production requirements, long-term use of artificial ruler method, labor-intensive, trouble-free operation, workers in direct contact with high temperature oil and gas poor working conditions . Early last year, I plant to achieve continuous oxidation of asphalt tower
