【摘要】 采用羰基法生产羰基铁粉的过程中,液态五羰基铁液体经过贮罐压力自压后进入蒸发器中进行蒸发,蒸发形成的五羰基铁气体进入与之相连的分解器中进行分解,从而生产出各种指标的羰基铁粉。本文主要讨论了羰基铁粉生产过程中的关键设备-五羰基铁蒸发器的控制参数,其中蒸发器液位计的控制尤为重要,在生产过程中液位计出现了不同形式的运行故障,根据故障现象进行分析并找到相应的解决方案。更多还原

【Abstract】 The liquid carbonyl iron go through the evaporator by the pressure to form gas of carbonyl iron then go into the decomposer to produce all kinds of carbonyl iron powder. The control parameters of evaporator in the key equipment in the production process of carbonyl iron powder were mainly discussed. The control of liquid level transmitter of evaporator is particularly important. The running faults of liquid level transmitter in production process were analysed and corresponding solutions were found.更多还原
