Nitrogen is a colorless, odorless and non-toxic gas, relatively stable, so it is usually used in chemical synthesis and as a protective gas and so on. The equipment for making nitrogen is a nitrogen generator, and the nitrogen generator cannot work without an air compressor.
The compressed air required by the nitrogen generator must be dry, oil-free and clean compressed air with a pressure above 0.6Mpa and below 0.8Mpa. Because the molecular sieve of the nitrogen equipment of the nitrogen making mechanism has a good adsorption effect at this pressure. So when choosing an air compressor, it is best to choose an oil-free air compressor. Sometimes considering the relatively high price of oil-free air compressors, try to choose micro-oil air compressors as much as possible, but the post-processing equipment needs to be equipped with degreasers to ensure that the compressed air is relatively clean.
If it is a food nitrogen generator used in the food industry, it is recommended to choose an oil-free air compressor. So how big an air compressor should be selected for a nitrogen-making mechanism nitrogen equipment? Here we have a calculation method, the amount of compressed air required by the nitrogen-making mechanism nitrogen equipment with a purity of 99.9% is 6 times that of the nitrogen produced by the nitrogen-making mechanism nitrogen equipment, for example, the compressed air volume of a 3 cubic nitrogen-making mechanism nitrogen equipment Not less than 0.3m3/min per minute.
If the amount of compressed air required by the nitrogen-making mechanism nitrogen equipment with a purity of 99.99% is 8 times that of the nitrogen produced by the nitrogen-making mechanism nitrogen equipment, for example, the compressed air volume of a 5 cubic nitrogen-making mechanism nitrogen equipment is not less than 0.6m3/min. I hope this method can make it easy for you to choose the air compressor needed for the nitrogen equipment of the nitrogen generator.
The selection of air compressors for nitrogen generators is mainly determined according to the needs and purposes. When necessary, energy-saving air compressors can also be considered. Wuxi Youteng Machinery always pays attention to high-efficiency, energy-saving, quiet, and better-quality air compressors, and provides you with a complete set of compressed air system solutions.
