Laboratory nitrogen generator improves the utilization rate of adsorbent

　　The laboratory nitrogen generator uses compressed air as raw material, and uses an adsorbent called carbon molecular sieve to selectively adsorb nitrogen and oxygen to separate nitrogen from the air. The separation effect of carbon molecular sieve on nitrogen and oxygen is mainly based on the different diffusion rates of nitrogen and oxygen molecules on the surface of molecular sieve.

　　Oxygen molecules with a smaller diameter diffuse faster and enter the solid phase of the molecular sieve more; nitrogen molecules with a larger diameter diffuse slowly and less enter the solid phase of the molecular sieve. In this way, nitrogen is enriched in the gas phase. After a period of time, the molecular sieve can absorb oxygen to a certain extent. Through decompression, the gas adsorbed by the carbon molecular sieve is released, and the molecular sieve is also regenerated. This is based on the characteristic that molecular sieve has different adsorption capacity for adsorbed gas under different pressures. The laboratory nitrogen generator usually uses two parallel adsorbers to alternately perform pressure adsorption and decompression regeneration, and the operation cycle is about 2 minutes.
　　The laboratory nitrogen generator uses natural air as the raw material and adopts an energy-saving design process to ensure high nitrogen production with low raw material air. The whole machine consumes less power, and the cost of environmentally friendly nitrogen production is low. The advanced adsorber design completely gets rid of the traditional " The design concept of “diameter-to-height ratio”, the structure size of the adsorber depends on the size of the gas flow and the characteristics of the molecular sieve. The unique air flow distributor design prevents the air flow from short-circuiting the channel flow, so that the flow rate of the air flow in the adsorption bed is more uniform, thereby improving the utilization rate of the adsorbent.
　　The laboratory nitrogen generator adopts an automatic compression cylinder device and a unique air intake method, so that the airflow direction in the adsorber is always unchanged, avoiding fatigue and wear of the adsorbent during frequent switching cycles, and effectively ensuring that the adsorbent is up to 10 years The service life of the adsorbent and the inertia loading method of the adsorbent make the packing density of the adsorbent greater and the packing tighter, preventing the peristaltic and powdering of the adsorbent, making the adsorption and separation efficiency better, and further ensuring and correspondingly extending the adsorbent life.
