The economy of an oxygen concentrator mainly refers to the cost required to produce a unit product (per 1m3 of oxygen). The cost includes electricity consumption, water consumption, fuel consumption, steam consumption, auxiliary material consumption, maintenance costs, and production management expenses. We should start from the following aspects:
1) Reduce the operating pressure of the oxygen concentrator to reduce the power consumption of the air compressor. To this end, the resistance of equipment and pipelines should be minimized as much as possible, and the pressure on the tower should be reduced; A certain liquid level of the main cooling system should be maintained to ensure that the main cooling system operates under the optimal heat transfer conditions, in order to reduce the temperature difference between the main cooling system and the lower tower pressure; Minimize cold damage as much as possible.
2) Improve the efficiency of the compressor. Firstly, it is necessary to strengthen the management of the intercooler to ensure good air cooling.
3) Increase the amount of air. To reduce switching losses and prevent leakage, so that more processing air can enter the tower for separation.
4) Increase oxygen production and improve oxygen extraction rate. Efforts should be made to reduce the oxygen content in nitrogen during the adjustment.
5) Extend the continuous operation cycle of the equipment and reduce downtime for maintenance. To this end, it is necessary to strengthen the daily maintenance of the equipment and regularly inspect the equipment. To ensure the removal effect of moisture and carbon dioxide.
6) Absolute avoidance of leakage of low-temperature liquids and gases inside the tower. When heating individual equipment, the temperature should not be too high.
7) Produce multiple products through comprehensive utilization.
