Industrial oxygen generator process flow

Industrial Oxygen GeneratorIt is favored by users for its significant advantages. Industrial oxygen generators are widely used in metallurgy combustion, environmental protection, medical, chemical, aquaculture, building materials, biotechnology, light industry, and wastewater treatment.

Air is compressed by an air compressor,Industrial Oxygen GeneratorAfter dust and oil removal, it enters the storage tank. After drying, it enters the left adsorption tower through the inlet valve and the left inlet valve. The pressure in the tower rises, and the nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve. The unadsorbed oxygen passes through the adsorption bed, and the industrial oxygen generator enters the oxygen storage tank through the left and oxygen production valves. This process is called left suction and lasts for tens of seconds. After the left suction process is completed, the right adsorption tower and the left adsorption tower are connected through a pressure equalization valve to equalize the pressure of the two towers. This process is called pressure equalization and lasts 3-5 seconds. After pressure equalization, the industrial oxygen generator-compressed air enters the right adsorption tower through the inlet valve and the right inlet valve. The nitrogen molecules in the compressed air are adsorbed by the zeolite molecular sieve, and the oxygen-enriched air enters the oxygen storage tank through the right and oxygen production valves. This process is called right suction and lasts for tens of seconds. At the same time, the oxygen adsorbed by the zeolite molecular sieve in the left adsorption tower is depressurized and released back into the atmosphere through the left exhaust valve, which is called desorption. Conversely, when the left tower adsorbs, the right tower desorbs simultaneously. After the right suction, the pressure equalization process is entered, and then the process switches to the left suction process, which is continuously carried out to continuously produce high-purity product oxygen. In order to depressurize the molecular sieve and completely discharge the released nitrogen into the atmosphere, oxygen is used to purge the adsorption tower through the normally open backwash valve to blow the nitrogen out of the adsorption tower. This process is called backwashing and is carried out simultaneously with desorption.

The working process of the industrial oxygen generator is controlled by a programmable controller and five 2-position 5-way pilot solenoid valves. The opening and closing of ten pneumatic pipeline valves are then controlled by the solenoid valves. In the power-off state. The pilot gas of the five 2-position 5-way pilot solenoid valves is connected to the closing port of the pneumatic pipeline valve. The five 2-position 5-way pilot solenoid valves control the left suction pressure equalization and right suction states. The time and flow rate of left suction, pressure equalization, and right suction are stored in the programmable controller. When the process is in the left suction state, the solenoid valve controlling the left suction is energized. The pilot gas is connected to the opening of the left suction valve, the left suction valve, and the right exhaust valve. These three valves are opened to complete the left suction process and desorption in the right adsorption tower. When the process is in the pressure equalization state, the solenoid valve controlling the pressure equalization is energized, and other valves are closed; the pilot gas of the industrial oxygen generator is connected to the opening of the pressure equalization valve, so that the valve is opened and the pressure equalization process is completed. When the process is in the right suction state, the solenoid valve controlling the right suction is energized.Industrial Oxygen GeneratorThe pilot gas is connected to the openings of the right suction valve, the right suction production valve, and the left exhaust valve. These three valves are opened to complete the right suction process and desorption in the left adsorption tower. In each process, all valves except the valves that should be opened should be closed.
