氢气回收装置、
Hydrogen recovery unit
氢气是大规模工业生产制取金属粉末的主要还原气和保护气，它的用量之大，要求之高，是安全生产和控制经营成本必须重视的一个重要方面。将二次还原炉排出含有固体杂质和气体杂质的氢气，经过除去气体杂质，进入干燥塔，经分子筛吸附后，达到需要的露点。最后将净化后的氢气送入一次还原炉
设备特点：
1、 QW-型氢气回收装置为还原炉配套设备，必须满足还原炉的安全生产和工艺要求。假如系统里出现负压，立即有自动控制装置，充氮气保护。
2、 回收氢气经过滤器过滤后，减少罗茨风机维修量。
3、 再生罗茨风机保证干燥塔的再生效果。
4、 动排水器减小员工的工作量。
5、 为了还原炉的安全生产和工艺要求，还原炉进出料有连锁装置，各阀门的开、关有保护装置。
Hydrogen recovery unit
Hydrogen is preparing a large-scale industrial production of metal powder mainly reducing gas and shield gas, a large amount of its requirements of high security is an important aspect of the production and control of operating costs must be given attention. The second reduction furnace exhaust gas and solid impurities containing hydrogen impurities, after removal of gaseous impurities into the drying tower, the molecular sieve, the dew point required. Finally, the purified hydrogen gas is fed to the first reduction furnace
Features:
1, QW- type hydrogen recovery unit for the reduction furnace equipment must meet the safety requirements of the production process and reduction furnace. If the negative pressure system appeared immediately with automatic control devices, filling with nitrogen.
2, hydrogen recovery after filter and blower reduce the amount of maintenance.
3, to ensure the regeneration regenerative blower drying tower.
4, dynamic drainage reduce staff workload.
5, in order to restore safety in production and process requirements furnace, reduction furnace interlocks have access to materials, the valves opening and closing of the protective devices.
