[Chemical Knowledge]：Working Principle and Application of Nitrogen Making Machine

Read： 239 Time：13months ago Source：Transform the World with Simplicity

Nitrogen making machine is a common gas separation equipment, which can separate the nitrogen in the air for application in all walks of life. The working principle of the nitrogen generator is based on molecular sieve technology. Molecular sieve is a substance with a specific pore size. In this substance, molecules will be separated when passing through the pore size. The nitrogen generator uses this molecular sieve principle to separate nitrogen and oxygen in the air for application in different fields.

nitrogen generator is mainly composed of air compressor, cooler, molecular sieve, nitrogen storage tank and flow meter. The whole process can be divided into the following steps:

1. Air compression. The air is compressed by a compressor to increase the pressure of the gas, so that the heat is concentrated in a small space.

2. Cooling. The compressed gas needs to be cooled. The cooler can disperse and cool the heat, thereby activating the molecular sieve.

3. Separation. Nitrogen and oxygen have different molecular sizes, so they are gradually separated in the molecular sieve.

4. Storage. The separated nitrogen will be stored in a nitrogen storage tank for use. The separated oxygen then re-enters the atmosphere.

nitrogen making machine is widely used in many industries, such as medicine, chemical industry, electronics, metal processing, food and other industries. One of the most common applications is in the medical field. The pharmaceutical industry requires the use of high purity nitrogen to ensure the safety and effectiveness of medical procedures. In addition, the food industry needs to inject nitrogen into food packaging bags to prevent food from oxidizing or spoiling. The working principle of the

nitrogen making machine is based on molecular sieve technology, which can separate nitrogen and oxygen in the air. Nitrogen generator has a wide range of applications, including medicine, food, chemical, electronics and other industries. With the increasing demand for gas purity, nitrogen generator will play a more important role in more industries and fields.
