Compact Structure And Integral Skid Mounted PSA Nitrogen Generator To Produce High Purity Nitrogen

Working Principle Description:

Pressure swing adsorption nitrogen equipment uses carbon molecular sieve as adsorbent and uses the principle of pressure swing adsorption to obtain nitrogen. Under a certain pressure, the difference in the adsorption capacity of oxygen and nitrogen in the air on the surface of carbon molecular sieve is used, that is, the diffusion adsorption of oxygen by carbon molecular sieve is much greater than that of nitrogen. Through programmable control of the opening and closing of pneumatic valve, the process of alternating circulation of tower a and Tower B, pressurized adsorption and decompression desorption is achieved to complete the separation of oxygen and nitrogen and obtain nitrogen with the required purity.

Product Advantages:

●The equipment has compact structure, integral skid mounted, small land occupation, no capital investment and less investment. Nitrogen can be produced only by connecting power supply on site.

●PSA process is a simple nitrogen production method, which takes air as raw material and consumes only the electric energy consumed by the air compressor. It has the advantages of low operation cost and low energy consumption.

●Mechatronics design realizes automatic operation, imported PLC control fully automatic operation, nitrogen flow and pressure purity can be adjusted and continuously displayed, and unattended can be realized.

Application fields:

PSA Nitrogen generator is a set of equipment that can extract nitrogen. Its main application fields are: aerospace, nuclear power, food and medicine, petrochemical industry, electronic industry, material industry, national defense and military industry and scientific experiments, such as:

Special nitrogen making machine for metallurgical industry ---- suitable for heat treatment, bright annealing, protective heating, powder metallurgy, copper and aluminum processing, magnetic material sintering, precious metal processing, bearing production and other fields. It has the characteristics of high purity, continuous production, and some processes require nitrogen to contain a certain amount of hydrogen to increase brightness.

Special nitrogen generator for coal mining industry ---- applicable to the fields of fire prevention and extinguishing, gas and gas dilution in coal mining. It has three specifications: ground fixed type, ground mobile type and underground mobile type, which can fully meet the nitrogen demand under different working conditions.

Technical parameters:

● Nitrogen delivery ≤500Nm3/hr;

● Purity 95%

● Pressure 0.5~0.8 Mpa

● Atmospheric dew point ≤－40℃
