Nitrogen making machine is a commonly used nitrogen making equipment in industry

Nitrogen machine is commonly used in industry nitrogen production equipment, with the first technology, together with the air flow distributor, about 20 minutes to supply qualified nitrogen. The nitrogen making machine uses high-quality imported carbon molecular sieve as adsorbent, and adopts the principle of pressure swing adsorption at normal temperature to produce high purity nitrogen. Usually the two adsorption towers are connected in parallel, the imported pneumatic valve is controlled by the imported PLC to work automatically, the replacement is pressurized adsorption and decompression regeneration, the end of nitrogen and oxygen respectively, and the required high purity nitrogen is obtained. The cryogenic air separation nitrogen production equipment is messy, covers a large area, has high infrastructure costs, more one-time investment of equipment, and higher working cost, which is a traditional nitrogen production method, which has a history of recent decades.

The cryogenic air separation of nitrogen is based on air as a material, through tightening, purification, and then the use of heat exchange to liquefy the air into liquid air. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen, using liquid oxygen and liquid nitrogen boiling points are not the same, through liquid air rectification, so that they are respectively to obtain nitrogen. Compared with the traditional nitrogen production method, the molecular sieve air separation nitrogen production equipment has the characteristics of simple process flow, high degree of automation, fast gas production, low energy consumption, product purity can be scheduled in a large range according to the needs of users, easy operation and maintenance, low working cost, and strong equipment adaptability.
