氮气纯化装置、
Nitrogen purification unit
原氮经原气阀,氮流量计，除氧器，氢气经加氢阀 ，加氢流量计计量与氮气混合，进行催化除氧。再经冷却器降温，用冷却水使气体降温，进入汽水分离器，分离水份。再经冷凝器，用冷冻水使气体深度干燥，经汽水分离器分离水份。
此时气体可以分别经阀门，进入1组吸附干燥器或2组吸附干燥器吸附干燥，然后经阀门，再经过滤器，纯氮由纯氮出口阀门13送使用地点。
该复式流程，在一只吸附干燥器工作的同时，另一只吸附干燥器可以进行再生处理，再生用气取部分干燥纯氮，通过阀门，再生流量计，阀门送1组吸附干燥器或2组吸附干燥器，加热再生吸附剂，再生废气经阀门进入汽水分离器放空，水份经阀门排出。
高效吸附剂和高效过滤器除去氮气中的杂质氧、水汽和尘埃等。本装置采用复式流程，一组工作，同时另一组再生、待用。两组交替使用，设备可以长期连续运行。
复式流程，每一组由除氧器、冷却水、干燥器串联组成，可以一组工作，同时另一组可以进行再生处理，相互交替工作和再生，以保证设备连续运行。
1组工作时，原料氮气级阀,过原气流量计，经阀进入1组除氧器，利用脱氧剂除氧，经1组冷却器冷却后，进入 1组干燥器，利用分子筛吸附性可以同时除去水份等杂质，然后气体经阀和过滤器，再经阀，由纯气出口送入使用点。
2组再生时，取一部分纯氮气通过再生流量计，阀，同时打开加氢阀，纯氢通过加氢流量计与氮气混合后，经阀送入2组干燥器，进行加热冲洗再生，再生气经2组冷却器冷却，进入2组除氧器，利用氢气对除氧器进行再生处理，再生气经阀放空
Nitrogen purification unit
Reduction of nitrogen by the original valve, flowmeter nitrogen, oxygen, a hydrogen valve via hydrogenation, hydrogen is mixed with nitrogen gas flowmeter, catalytic oxygen. And then the cooler cooling, cooling water to cool the gas into the water separator, water separation. And then by a condenser with chilled water depth of the gas drying, separation of water through the steam separator.
In this case the gas can respectively through the valve into the Group 1 or Group 2 adsorption dryer adsorption dryer adsorption drying, and then through the valve, and then through the filter, pure nitrogen from the nitrogen outlet valve 13 to send the point of use.
The duplex process, while working a suction drier, the other can be regenerated adsorption dryer regeneration dried nitrogen gas to take part, through the valve, regeneration flow meters, valves get 1 or 2 groups adsorption dryer group adsorption dryers, heating the adsorbent regeneration, regeneration of exhaust gas through the vent valve into the steam separator, water is discharged through the valve.
Efficient adsorbent and high efficiency filter to remove impurities in the oxygen-nitrogen, water vapor and dust. The device uses dual process, a group of work, while another group of regeneration, and set aside. Two alternate use, the device can be long-term continuous operation.
Duplex process, each group consisting of oxygen, cooling water, the dryer in series, a group can work, while another group can be regenerated, alternating work and regeneration to ensure continuous operation of equipment.
1 group work, material grade nitrogen valve, over the original gas flow meter, through the valve into the group deaerator using deoxidizer oxygen, after a group of cooler, drier into the group, you can use molecular sieve adsorption while removing water and other impurities, and then through the gas valve and filter, then through valve, made of pure gas outlet into the point of use.
2 regeneration group, a part of pure nitrogen through the regeneration meter, valve and opens the valve hydrogenation, hydrogenation of pure hydrogen mixed with nitrogen flow meter, the two groups through the valve into the dryer, heated wash regeneration, regeneration gas cooler by the two groups into two groups deaerator, deaerator use hydrogen to be regenerated, the regeneration gas through the vent valve |
