氢气回收系统

该系统的回收原理来源于还原炉或退火炉排出的废氢或氨分解气,首先进行降温淋洗除尘,冷凝出废氢气中的大部分水份后进入风机进行增压;经风机加压处理后的废氢气进入氢气净化装置进行二次处理,使得气体的氧含量及露点降低到合同要求的指标;经净化后的氢气重新作为原料气供给还原炉设备循环往返使用。

The principle of the process in hydrogen recovery system is originated in the waste hydrogen or ammonia  gas discharged from the reduction furnace and the annealing furnace. Through the process of cooling, leaching and dust precipitating, the condensated waste hydrogen gas will go into the booster to increase pressure, then the treated waste hydrogen gas will go into the hydrogen purifier to carry on to the secondary treatment which its oxygen content and dew point should be lowered to the agreed level according to the contract. Purified hydrogen will be applied to the furnace as raw gas and is recycled.
