一种硫化亚铁气相钝化装置
摘要：
本发明公开了一种硫化亚铁气相钝化装置，包括蒸汽供给部件、氧气供给部件和密封部件。所述气相钝化装置，分别与尾气处理装置和数据分析装置相连，用于对石化装置进行气相钝化。所述蒸汽供给部件进一步包括：软水器、蒸汽发生器、蒸汽流量计和氧气阀门。所述氧气供给部件进一步包括：压缩富氧空气瓶、气体流量计、氧气进气阀门和氧气阀门。所述密封部件进一步包括：填料塔、尾气阀门和集油罐阀门。相比现有技术中的液相钝化方法，气相钝化主要使用富氧空气，使用便捷，成本较低。废气处理容易。气相钝化后的废气经简单处理后即可达到排放标准。处理时间短。钝化均匀，不存在沟流现象。
摘要（英）：

The invention discloses a ferrous sulfide gas phase passivation device. The gas phase passivation device contains a steam supply part, an oxygen supply part and a sealing part. The gas phase passivation device is connected with a tail gas treatment device and a data analysis device respectively to perform gas phase passivation to a petrochemical device. The steam supply part contains a water softener, a steam generator, a steam flowmeter and an oxygen valve. The oxygen supply part contains a compressed oxygenized air bottle, a gas flowmeter, an oxygen inlet valve and an oxygen valve. The sealing part contains a packed tower, a tail gas valve and a gathering tank valve. Compared with the liquid phase passivation method in the prior art, the phase passivation method of the invention mainly uses oxygenized air, is convenient to use and has lower cost. Waste gas is easy to treat. The waste gas which is easily treated through gas phase passivation can meet the emission standard. The treatment time is short; and passivation can be performed evenly and the channeling phenomenon does not exist.
