Abstract
Description
technical field
[0001] The invention relates to pressure swing adsorption nitrogen production equipment, which belongs to the technical field of nitrogen production equipment. Background technique
[0002] Pressure swing adsorption (referred to as PSA) is a new gas separation technology, which uses air as the raw material and uses a high-efficiency, high-selection solid adsorbent to selectively adsorb nitrogen and oxygen to remove nitrogen from the air. separated from oxygen.
[0003] In the existing technology, the adsorption tower in the pressure swing adsorption nitrogen production equipment will have a purification device in front of it. The purification device is used to absorb moisture and particulate matter in the air, so that dry and clean air enters the adsorption tower for nitrogen and oxygen separation. , if the moisture-containing air enters the adsorption tower, it will make the adsorption tower humid, and it is easy to accumulate dust and cause blockage. It is...
