As an inert gas, nitrogen reacts slowly with other substances, so nitrogen is widely used in various industries. The proportion of nitrogen in the air is very high, reaching 78%, and obtaining high purity nitrogen from the air is economical and feasible.
Pressure swing adsorption nitrogen generator (PSA nitrogen generator), is the use of molecular sieve as adsorption material, according to the principle of pressure swing adsorption from the air to produce nitrogen equipment. Jiangsu Luoming nitrogen generator is composed of these systems: compressed air system, air purification system, PSA nitrogen making machine system.
Using clean compressed air as raw material and carbon molecular sieve as adsorbent, according to the differences in the adsorption amount of oxygen and nitrogen in the air on the surface of the carbon molecular sieve and the different diffusion rates of oxygen and nitrogen in the carbon molecular sieve, the programmable controller is used to control the opening and closing of the program control valve to realize the process of pressurized adsorption and decompression desorption, complete the separation of oxygen and nitrogen, and obtain the required purity of nitrogen.
Compared with the traditional nitrogen production method, it has the characteristics of simple process, high degree of automation, fast gas production (15-30 minutes), low energy consumption, product purity can be adjusted in a large range according to the needs of users, easy operation and maintenance, low operating cost, and strong adaptability of the device, so it is very competitive in the nitrogen production equipment below 1000Nm3 / h. More and more popular with small and medium nitrogen users, PSA nitrogen has become the preferred method for small and medium nitrogen users.
1. Air compressor system
The raw air is collected and pressurized to obtain compressed air
2. Air purification system
Remove water, oil and other impurities from the compressed air through the filter in the equipment
3. Pressure swing adsorption nitrogen machine system
In the molecular sieve adsorption tower, the working principle of pressure adsorption and decompression desorption is used to separate oxygen and nitrogen in the "compressed air". It is a physical process, carried out at room temperature and does not cause environmental pollution.
4. Nitrogen collection system
The high-purity nitrogen obtained by separation and enrichment enters the nitrogen buffer tank and outputs stably according to the flow rate and pressure required by customers.
At Jiangsu Luoming, we have been providing air separation equipment for PSA systems for more than 25 years. We have mature technology, professional service, reasonable price. We have cases in various application industries of nitrogen generators, and we can recommend the right type of nitrogen generator according to your needs.
