摘要
分析了2#14000Nm3/h制氧机在投产时存在的板式热端温差大的问题;并利用检修的机会,在板式冷箱内增加了一台主板式换热器以解决换热面积不足的问题。检修后发现,氧、氮、氩产量纯度得到了大幅地提升。
The temperature difference at warm end of the No2 14000Nm^3/h oxygen producing device was large when it was put into production. A main heat exchanger was added to the ice chest during checking and repairing, the problem of insufficient heat-exchange area was solved. Purity of oxygen ,nitrogen and argon is increased eividently after checking and repairing.
