Nitrogen Generator For Packaging

Nitrogen generator for packaging is an on-site nitrogen generation equipment specially designed for the packaging industry. It mainly uses pressure swing adsorption or membrane separation technology, and can instantly produce nitrogen of the required purity according to the actual needs of the packaging line. This equipment solution gives packaging companies great flexibility and autonomy, ensuring the continuity of the production process and the optimization of gas costs.

Working principle

At present, the packaging industry mainly uses pressure swing adsorption nitrogen production technology:

1. Compression and purification: After the ambient air is compressed by the compressor, it enters the precision filter and cold dryer to remove impurities such as oil, water, and dust to obtain clean compressed air.

2. Adsorption separation: Clean compressed air enters the adsorption tower filled with carbon molecular sieves. Carbon molecular sieve has the characteristics of dynamically adsorbing oxygen, carbon dioxide and moisture, while nitrogen is not easily adsorbed due to its large molecular diameter, and is thus enriched in the gas phase to form a high-purity nitrogen product.

3. Pressure reduction regeneration: When the carbon molecular sieve in one adsorption tower is saturated, the system will automatically switch to another adsorption tower to continue working. At the same time, the saturated adsorption tower quickly releases pressure, desorbs and empties the adsorbed oxygen and other impurities, and regenerates the carbon molecular sieve.

4. Cycle alternation: The two adsorption towers alternately perform adsorption and regeneration steps through a precise PLC control system to ensure continuous and stable output of nitrogen.

Note: Nm³/h refers to standard cubic meters per hour.

Maintenance and precautions

To ensure long-term stable operation of the equipment, please note:

• Regularly replace the pre-filter element: This is the key to protecting the life of the carbon molecular sieve, and the maintenance cycle must be strictly followed.
• Monitoring the performance of carbon molecular sieves: Under normal working conditions and good pretreatment, the lifespan of carbon molecular sieves can reach 8-12 years.
• Keep the environment clean and ventilated: Avoid operating equipment in dusty, high-temperature and high-humidity environments.
• Professional training: Operators should receive basic training to understand the equipment operating status and alarm information.
