Description

Technical Field

[0001] The utility model belongs to the technical field of nitrogen purification, and specifically relates to separation equipment for nitrogen purification. Background Art

[0002] The carbon-nitrogen separation pressurized reaction tank is filled with an adsorbent that has selective adsorption capacity for nitrogen or carbon-containing gases (such as carbon dioxide, carbon monoxide, etc.). Under pressurized conditions, one gas is preferentially adsorbed, while the other gas passes through the tank body, thereby achieving separation. The pressurized method can increase the partial pressure of oxygen in the mixed gas, which will cause more oxygen molecules to be adsorbed on the activated carbon;

[0003] When the nitrogen in the pressurized separation equipment is purified by carbon, the oxygen contained in the nitrogen can be adsorbed by the carbon. The carbon has a good suitability for oxygen. When the carbon adsorbs oxygen to a certain extent, the nitrogen still contains a certain amount of oxygen. At this time, the carbon is in the sealed pressurized nitrogen. When the carbon is taken out at this time, the equipment will be connected to the outside world, affecting the purification effect of the nitrogen, making it inconvenient to replace the carbon in the equipment to ensure the absorption of oxygen in the nitrogen and purify the nitrogen.
