Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen production, in particular to a nitrogen production adsorption cylinder. Background Technique

[0002] Pressure swing adsorption nitrogen production method is widely used in the air separation industry due to its low cost, high efficiency and energy saving. The performance of the nitrogen generator basically depends on the performance of the molecular sieve. The quality of the molecular sieve directly affects the nitrogen output and purity of the produced nitrogen. However, the air contains substances such as water, oil, and carbon dioxide, and the molecular sieve is extremely sensitive to water, oil, carbon dioxide, etc. After contact, it will reduce the adsorption of nitrogen or oxygen by the molecular sieve. Therefore, the pressure swing adsorption nitrogen production equipment must remove impurities such as water, oil, and carbon dioxide before the compressed air enters the oxygen-nitrogen separation device. However, some nitrogen production equipment often causes the molecular sieve in the nitrogen generator to be contaminated due to the damage of the purification equipment, and there is currently no effective and economical molecular sieve regeneration technology in the industry. Therefore, the contaminated molecular sieve must be replaced.

[0003] The existing adsorption cylinder has some defects: the carbon molecular sieve in the existing adsorption cylinder is installed inside the adsorption cylinder, and it is necessary to disassemble the adsorption cylinder to take out the carbon molecular sieve for replacement, which is very inconvenient, affects the work efficiency, and the disassembly may affect the sealing performance of the adsorption cylinder. Each installation requires checking the sealing performance, which is time-consuming and laborious.
