放射性废液油水分离槽液位监测

Level Monitoring of Oil-water Separation Tank for Radioactive Waste Liquid

放射性废液含有大量放射性废磷酸三丁脂/煤油(TBP/OK)溶剂。为了便于分离废液中的有机相,监测放射性废液的液位,对其采用油水分离法提取TBP/OK。它主要利用吹气技术,采用液体压强原理计算油水分离槽的密度,界面高度和液面高度,实现对油水分离槽的液位监控,使贮罐油水分离,并对贮槽密度测量提出改进方法,提高系统测量精度。具有实用性强,成本低、精度高、容易实现自动化等特点。

The radioactive waste liquid contains a large amount of waste radioactive tributyl phosphate/kerosene(TBP/OK) solvent. In order to facilitate the separation of the organic phase in the waste liquid and monitor the liquid level of the radioactive waste liquid, the oil-water separation method is used to extract TBP/OK. It mainly uses air blowing technology and uses the principle of liquid pressure to calculate the density, interface height and liquid level of the oil-water separation tank, realizes the liquid level monitoring of the oil-water separation tank, separates the oil and water in the storage tank, and proposes an improved method for the density measurement of the storage tank, Improve system measurement accuracy. It has the characteristics of strong practicability, low cost, high precision, easy to realize automation, etc.
