Nowadays, in the industrial development, many industries have begun to use nitrogen to produce or assist in producing products, which is widely used. Therefore, it is necessary for us to understand the generation principle of pressure-changing adsorption nitrogen generator.
Variable Pressure adsorption nitrogen generator is a new gas adsorption separation technology. The product has high purity, and can work at room temperature and under low pressure. It is energy-saving and economical, with simple equipment, easy operation and maintenance, and can achieve complete automation through continuous circulation operation. The pressure-changing adsorption nitrogen generator is a nitrogen generating equipment designed and manufactured according to the pressure-changing adsorption technology. Usually two absorption towers are used in parallel, and the automatic control system strictly controls the time series according to specific programmable procedures, and conducts pressure adsorption and decompression regeneration alternately to complete the separation of nitrogen and oxygen and obtain the required high purity nitrogen. Characteristics of pressure-changing adsorption nitrogen generator the unique molecular sieve filling technology and perfect overall design save the power consumption and the lowest operating cost at the same time of nitrogen concentration and gas production. Adopting the molecular sieve with the best performance in the world at present, combining with the unique gas distribution technology and specific technological process, to maximize the energy efficiency of the molecular sieve, the best recovery rate of nitrogen is mainly based on the different adsorption rates of carbon molecular sieve on oxygen and nitrogen. Carbon molecular sieve preferentially adsorbs oxygen, while most nitrogen is enriched in the non-adsorption phase. The carbon molecular sieve itself has the characteristics of increasing the adsorptive capacity of oxygen under pressure and decreasing the adsorptive capacity of oxygen under pressure. Use this characteristic of pressure-changing adsorption to realize the separation of oxygen and nitrogen and get the gas components we need. Since the Adsorbents have a certain adsorption capacity, it needs regeneration when the adsorption is saturated, so the adsorption of single adsorption bed is intermittent. In order to ensure continuous gas supply, double adsorption towers are adopted to carry out the adsorption alternately in parallel, one tower works and one tower regenerates, producing nitrogen continuously.
Product Features
Nitrogen is widely distributed in nature and is the main component of air. It mainly exists in the atmosphere in the form of simple substance molecule nitrogen. In the dry air, the volume of N2 accounts for 78.03% of the air, therefore, air is the largest raw material warehouse for producing nitrogen, which is inexhaustible.
The pressure-changing adsorption oxygen generator consists of two or more absorption towers, which are controlled by the computer to work respectively in the processes of pressure filling, adsorption, regeneration, washing and so on to realize continuous gas supply.
The equipment includes: Compressed air source and purification system, variable pressure adsorption oxygen and nitrogen separation components, storage and gas supply system and automatic control system.
Application: This device has low energy consumption, simple operation and low equipment investment. It is widely used in petrochemical, light industry, metallurgy, environmental protection, building materials, aquaculture, biotechnology, medicine and medical treatment, etc.
