摘要
针对某电厂200 MW机组调速系统用磷酸酯抗燃油在使用过程中出现了酸值升高、电阻率降低、泡沫特性超标等问题,笔者从系统性和化学因素分析了油品劣化变质的原因,根据不同设备处理油品效果的对比实验,发现现有的抗燃油处理设备只能去除油中的水分和杂质,不能去除油中深层次的劣化产物,并提出了抗燃油再生处理方法。实践证明,通过选择适当的再生吸附剂对劣化的抗燃油进行再生处理,可以恢复抗燃油自身的良好性能,解决磷酸酯抗燃油运行过程中劣化变质的问题,保证调速系统安全运行。
Aiming at the issues that caused higher acid value, lower resistivity and over standard of foam character-istics in the process of using phosphoester fire - resistant oil for 200 MW unit speed control system, the author ana-lyzed the causes of oil deterioration from systemic and chemical factors. Accordingly, based on the contrast experi-ments which showed variable effects in different oil processing devices, it is found that only fire - resistant oil treat-ment equipment is able to remove oil in water and impurities, instead of removing the deeply deteriorated products in oil. Therefore, the fire resistant oil recycling treatment method was put forward. Practice shows that, through re-cycling treatment to deteriorated fire resistant oil by selecting the appropriate recycling absorbent, good fire resist-ance property of its own can be restored and the problem of deterioration of phosphoester fire resistant oil during the operation is solved, ensuring the safe operation of speed control system.
