Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to an adsorption tower for nitrogen generators which is convenient for replacing adsorbent. Background Art

[0002] Nitrogen generators use air as a raw material and utilize physical methods to separate oxygen and nitrogen from it to produce nitrogen. In my country, nitrogen generators have developed rapidly and are widely used in industries such as metallurgy, petrochemicals, fertilizers, city gas, machinery, electronics, food, brewing, glass, and chemical fibers. Typically, two adsorption towers are connected in parallel, with imported pneumatic valves controlled by an imported PLC automatically operating. These towers alternate between pressurized adsorption and decompressed regeneration to separate nitrogen and oxygen, producing the desired high-purity nitrogen. However, existing adsorption towers in nitrogen generators have the following disadvantages: The adsorbent in the adsorption towers of existing technologies is not stratified, and the adsorbent is loaded using a vacuum or manual one-time loading method. When the nitrogen generator is in operation, most of the gas enters from the bottom of the tower and is discharged from the top of the tower. During this process, a large amount of air enters and is first adsorbed by the adsorbent at the bottom of the tower, then passes through the middle, and finally is discharged out of the tower through the adsorbent at the top. During this adsorption process, the impurities in the gas reaching the adsorbent at the top of the tower are obviously lower than those at the bottom and middle, resulting in different adsorption saturations of the adsorbent. Therefore, when the adsorbents at the bottom and middle reach the replacement time period, the adsorbent at the top can still be used. If a one-time filling and replacement is used, it will cause a waste of the top adsorbent. For this reason, an adsorption tower for a nitrogen generator that is convenient for adsorbent replacement is proposed. Utility Model Content
