PSA nitrogen generator from China factory with the features of low noise and high purity
- Working principle of High pressure oxygen generator:
PSA Oxygen Generator is an automatic equipment which takes clean and compressed air as raw material, ZMS (Zeolite Molecular Sieve) as adsorbent.
According to the differences of adsorption and diffusion between oxygen and nitrogen in ZMS, through controlling the programme on/off to realize pressure adsorption and decompression desorption so that to get the qualified oxygen. The whole system consists of the following components: compressed air purification module, air storage tank, oxygen and nitrogen separation device, oxygen buffer tank.
- Technical features of PSA industrial oxygen generator:
- Stable working condition to ensure the oxygen supplying continuously.
- Compressed air with the excellent quality can prolong the service life of molecular sieve that keeps the machine in a good situation;
- Low noise can protect the environment and provide a more comfortable circumstance for the staff;
- PLC control can conduct the machine intelligently, reducing the failure rate of operation;
- The qualified gas will be achieved within 20 minutes;
- Low energy consumption and low operating costs for power supply ;
- Low cost of labor because there is no need to control the machine by person;
- The solid and compact structure of molecular sieve can improve the efficiency and prolong the service life;
- The pressure, purity and flow rate can be adjusted to meet the different needs of customers;
- Reasonable structure, advanced process ensures the safe and stable of the machine;
- Compared with the high cost of bottled oxygen and liquid oxygen operation, oxygen making machine has the lowest cost of oxygen making. For enterprises engaged in medical treatment, plateau, breeding, environmental protection and combustion support for a long time, using oxygen making machine is the most cost-effective;
- Main Application Fields:
Oxygen-enriched combustion, industrial oxygen generator can be widely used in petrochemical industry, electric furnace steel making, paper making, glass production, making ozone, aquaculture, sewage treatment, aerospace and other industries and fields, for the different requirements of different users of different industries use of oxygen, since provide personalized, specialized oxygen equipment, fully meet the requirements of different users of gas.
PSA industrial oxygen generator system flow
- Compressed air purification units: Raw material is providing by this unit for the whole system. The material air keeps the low cost and it is quiet friendly to the environment.
- Air storage tank:The role of the air tank is to reduce the air pulsation of piston air compressor, improve the continuity and pressure stability of the output air flow, further precipitate and separate the water and oil in the compressed air, and ensure the continuous supply of enough air. Also, it can protect the compressor so it will serve for a longer time.
- Oxygen and nitrogen separation unit:There are two adsorption towers A and B which have special molecular sieve -- ZMS. N2 will be adsorbed and O2 will flow through the pipeline into tower B when the clean compressed air enters into the tower A. In tower A, the molecular sieve will be saturated after some time of adsorbing and it will stop adsorbing automatically. Then compressed air passes through tower B for absorption of nitrogen and production of oxygen. In tower A, the molecular sieve will be regenerated by the different pressure, as well as releasing the adsorbed nitrogen. These processes are controlled by the programmable logic controller (PLC). When the oxygen purity is lower than the rated one, PLC will evacuate the valve automatically to release the unqualified oxygen. It makes sure that the quality of the required gas and the unqualified one will not go back to the pipeline.
- Oxygen buffer tank:In order to keep the stability of supplying oxygen continuously, the oxygen buffer tank plays the role of balancing the pressure. Meanwhile, when switching of the adsorption tower, it will recharge part of the gas itself to the adsorption tower. On one hand, it helps to boost the pressure in adsorption tower. On the other hand, it can protect the bed of molecular sieve. It has contributed to the technological assistance greatly in the working process.
Precautions for safe use
- Oxygen is a dangerous gas that can aid combustion.Therefore, gas leakage in confined space should be prevented to avoid accident;
- Protection, safety signs and safety devices shall not be moved, altered or adjusted;
- When the equipment is working, the door of the electrical box should be closed and forbidden to open;
- Never start the machine in an unsafe state. If problems are found, do not attempt to start it;
- The highest working pressure should not be higher than the design pressure of the equipment (please refer to the nameplate for the design parameters of the equipment);
- The equipment shell must be grounded to avoid electrical accidents, and the use of gas must comply with gas safety regulations;
- Never operate the machine in the phase deficiency state (check the power supply has enough voltage and phase number before starting), or it will cause damage to the equipment;
- Failure to follow the procedures and precautions in the manual will result in the possibility of accidents and personal safety;
- Operators must comply with local work, operation and safety regulations and existing factory internal regulations
