Integrated oxygen production system

Abstract

The invention discloses an integrated oxygen production system, and relates to the field of oxygen production equipment. The system comprises a machine shell, the machine shell can be disassembled into two parts left and right, an air compressor is arranged in one part of the machine shell, and an adsorption tower set, a secondary precision filter and a pneumatic control valve are arranged in theother part of the machine shell. An air inlet is formed in a machine shell of the air compressor. A refrigeration dryer is arranged in the air compressor; the output end of the air compressor is connected with the input end of the secondary precision filter; and the output end of the secondary precision filter is connected with the input end of a group of pneumatic control valves, the output endsof the group of pneumatic control valves are connected with the input end of an adsorption tower group through an air distribution pipe, the output end of the adsorption tower group is connected withan oxygen supply pipeline through an oxygen distribution pipe, and a balance valve is arranged on the oxygen distribution pipe. Integrated design can be achieved, on-site installation is simple, on-site installation working hours are greatly shortened, and the overall service life is prolonged; and parts can be optimally configured, energy consumption is reduced, and the utilization rate is high.

Description

technical field [0001] The invention relates to the field of oxygen production equipment, in particular to an integrated integrated oxygen production system. Background technique [0002] With the gradual increase of people's requirements for environmental protection and pollution control, and the rapid development of molecular sieve pressure swing adsorption (PSA) technology, it has been widely used in steel production, gas industry, electronics industry, petrochemical industry, agricultural and sideline Many industries such as fishery and medical care. [0003] The pressure swing adsorption oxygen production system includes an air compressor, a cold dryer, a filter device, a molecular sieve adsorption tower and corresponding control devices. Using the principle of pressure swing adsorption, the clean compressed air enters the adsorption tower, and after being saturated by pressurized adsorption, regeneration Analyze the principle of nitrogen and oxygen separation.

AI Technical Summary

Problems solved by technology

[0004] The existing integrated molecular sieve PSA oxygen production system generally has problems such as complex structure, cumbersome system, poor integrity, high noise, high manufacturing cost, and poor energy efficiency ratio. The oxygen production is generally below 10 cubic meters per hour, and the oxygen production efficiency generally

Moreover, the cold dryer of the commonly used oxygen generation system is installed and controlled separately. If the cold dryer loses its function, the air compressor can work as usual. At this time, a large amount of compressed air will carry moisture into the molecular sieve adsorption tower, making the adsorption tower Molecular sieves quickly fail and cannot produce oxygen, resulting in damage to the oxygen production system and serious losses
