Fiber laser cutting machine onsite nitrogen generator

Fiber laser cutting machine Onsite Nitrogen Generator is one kind of Nitrogen Generator producing Nitrogen Gas from air. 

Specification:

Nitrogen purity: 99.99%,

Flow rate: 20 Nm3/hr

Outlet pressure: 30 barg

System combination

Air Compressor

Air compressor provides compressed air source for whole system, the flow and pressure are to be decided by the desired nitrogen flow rate, purity, outlet pressure. As it is the air source of whole system, the performance of air compressor has remarkable influence to the whole nitrogen generator system.

Air treatment part

Get rid of water, oil, impurities in compressed air coming from the air compressor, providing clean, dry, oil-free compressed air for the PSA nitrogen separator. It includes 3 filters, 1 Refrigerant Dryer and 1 activated carbon oil remover. After treatment, dew point of compressed air can reach -20 degree (normal pressure) , dust content is not larger than 0.01mg/m3, solid particles diameter is not larger than 0.01μ, oil mist content is not more than 0.003mg/m3.

Air receiver

It quickly increases the pressure of adsorption tower;

It also stores gas for air compressor, buffers system pressure；

Nitrogen separator

It is the key part of whole system. In this part, the nitrogen is separated from compressed air, sent to buffer receiver as produced gas. Oxygen, carbon dioxide, argon, etc. are discharge from muffler as exhausted gases. The efficiency of this machine is mainly decided by adsorption tower structure, air distribution structure, molecular sieve performance, process flow, etc.

Nitrogen buffer receiver

It balances pressure fluctuation, ensure stable nitrogen supply;

With nitrogen re-blowing system, this N2 buffer receiver can also quickly increases the pressure of adsorption towers.

Nitrogen Compressor

In order to get 30 barg pressure, one nitrogen compressor is supplied.
