Description
technical field [0001] The invention relates to the technical field of oxygen production, in particular to a pressure balance recovery pipeline for a molecular sieve adsorption integrated tower. Background technique [0002] The compressed air enters the molecular sieve adsorption tower, the molecular sieve absorbs the nitrogen in the air to separate the oxygen, and the nitrogen discharges the oxygen into the oxygen storage tank. [0003] Due to the pressure difference problem, the activity degree and analytical ability of the molecular sieve fluctuate greatly, and the oxygen purity varies greatly. The oxygen output is less than the designed output, which increases the workload of the oxygen production system. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a pressure balance recovery pipeline for a molecular sieve adsorption integration tower that ensures the purity...
