PSA oxygen generator is an automatic equipment which separate oxygen from air. According to the performance of molecular sieve, its adsorption when pressure risen and desorption when pressure loose. Molecular sieve’s surface and inner surface and interior are filled with micro pores. Nitrogen molecule has a faster diffusion rate of molecular sieve and oxygen molecules has a slower diffusion rate. Oxygen molecules are enriched in the end from the absorption tower. Oxygen generator is constructed according to the principle of operation PSA (pressure swing adsorption) and it compressed by two absorption towers filled up with molecular sieve. The two absorption towers are crossed by compressed air (previously purified oil, water,dust, etc) . While one of the absorption tower produce oxygen, the other one release nitrogen gas to atmosphere. The process comes in cycle way. The generator is controlled by PLC.

1. Advancement
PSA oxygen generator raw material is air , oxygen is produced and used on site. No need to be transported or filled.
Advanced PLC touch screen control and display, fully automatic operation, can be unmanned management.
2. Economical
PSA oxygen generator is physical principles, air as raw material, low cost, economical and environmentally friendly.
3. Safety
PSA technology through physical methods to produce oxygen at normal temperature and low pressure. No transportation link reduces

Mobile Nitrogen Gas Generator Specifications:

Application

Mainly used for steel-making converter, blast furnace top, pulverized coal injection in blast furnace, continuous casting and rolling, steel annealing, eliminating stress, aging and quenching heating, carburizing, carbon and nitrogen altogether permeability, soft nitriding, vacuum quenching nitrogen based atmosphere heat treatment such as nitrogen source, gas protection welding and powder metallurgy sintering process, and cleaning, dilute gas.

Controller: We choose the products of Siemens in Germany. The controller controls the whole nitrogen production automatically, without the need of personnel on duty, saving cost.

Loading method: the molecular sieve in the adsorption tower is loaded by the "snowstorm" method to obtain the maximum loading density, reduce the erosion of the molecular sieve, in the whole service life process, no need to add.

Nitrogen production technology: Aetok nitrogen production technology directly from Germany and Japan, process design, adsorption tower internal structure design, valve control, pipe design and other key technologies are provided by Germany and Japan, to ensure that the world class technology to serve our customers.

Product flows from adsorber mattress A right into a nitrogen product receiver previous to getting into the product piping. Simultaneously, adsorber mattress B is depressurised to atmospheric stress. Upon crowning glory of nitrogen manufacturing from adsorber mattress A, an equalisation step occurs. Adsorber mattress B (atmospheric stress) is pressurised to an intermediate stress because the fueloline ultimate in adsorber mattress A (at working stress) flows into adsorber mattress B. During this step, air isn't always ate up neither is product fueloline generated. Therefore a nitrogen receiver is carried out to allow for a consistent flow, purity and stress of the nitrogen product all through the PSA cycle. Adsorber mattress A then undergoes depressurisa
