The small liquid nitrogen generator uses the principle of pressure swing adsorption, and uses the selective adsorption of carbon molecular sieves to oxygen and nitrogen to separate nitrogen and oxygen, commonly known as PSA nitrogen production. It uses air as raw material, after compression, purification, and then use heat exchange to liquefy the air into liquid air. Liquid air is mainly a mixture of liquid oxygen and liquid nitrogen. Using the different boiling points of liquid oxygen and liquid nitrogen (under 1 atmosphere, the boiling point of the former is -183 °C, and the latter is -196 °C), through the rectification of liquid air , separate them to obtain nitrogen.
The small liquid nitrogen generator has the advantages of simple process flow, high degree of automation, fast gas production (15-30 minutes), low energy consumption, product purity can be adjusted according to user needs within a large range, convenient operation and maintenance, low operating cost, The device has the characteristics of strong adaptability, so it is quite competitive in nitrogen production equipment below 1000Nm3/h, and is more and more popular with medium and small nitrogen users. PSA nitrogen production has become the method for medium and small nitrogen users.
