Nitrogen machine equipment features: nitrogen production is convenient and fast: advanced technology, unique air distribution, so that the air distribution is more uniform, efficient use of carbon molecular sieve, about 20 minutes to provide qualified nitrogen. Mechanical and electrical integration design to achieve automatic operation: imported PLC control automatic operation, nitrogen flow pressure purity can be adjusted and continuous display, can achieve unattended. Easy to use: the equipment is compact in structure, the whole skid, occupies a small area without infrastructure investment, less investment, the field only needs to connect the power supply to prepare nitrogen. More economical than other nitrogen supply methods: PSA process is a simple nitrogen production method, using air as raw material, energy consumption is only the electric energy consumed by the air compressor, with low operating cost, low energy consumption, high efficiency advantages. A wide range of applications: metal heat treatment process protection gas, chemical industry production gas and all kinds of storage tanks, pipelines filled with nitrogen purification, rubber, plastic products production gas, food industry oxygen preservation packaging, beverage industry purification and covering gas, pharmaceutical industry filled with nitrogen packaging and containers filled with nitrogen and oxygen, electronic industry electronic components and semiconductor production process protection gas. Purity, flow, pressure stable and adjustable to meet the needs of different customers.

The process principle and structure composition of nitrogen making machine

First, the process principle of nitrogen making machine

When air pressure is raised, oxygen and nitrogen have different diffusion rates and different adsorption capacities on carbon molecular sieve to separate oxygen and nitrogen. The air is compressed to 0.8 ~ 1.0MPa, and after drying, oil-water separation (filter), the air source is purified and separated into the pressure shift adsorption tower. When pressurized, oxygen molecules are diffused and adsorbed in the carbon molecular sieve, and the unadsorbed nitrogen is discharged from the adsorption tower outlet. During depressurization, the oxygen in the adsorption tower is desorbed, discharged and washed, and the adsorbent is regenerated.

The nitrogen production process is shown in the figure below:

Second, the structure of the nitrogen machine

The whole nitrogen machine is composed of 5 systems:

1. Air supply system (air compressor, air storage tank);

2.Air purification system (activated carbon filter, etc.);

3. Oxygen and nitrogen separation system (adsorption tower, pipeline and solenoid valve);

4. Measurement and inspection system (product storage tank, flow meter, measurement and analysis);

5. Control system (computer controller)
