The economy of oxygen generator mainly refers to the production unit Products (per 1 m3Oxygen) the cost required. Cost cost includes power consumption, water consumption, fuel consumption, steam consumption, auxiliary material consumption, maintenance cost and production management cost, etc. In order to improve the economical efficiency of the operation of the oxygen generator, we should strive to produce more products and reduce the production cost.
In the cost, power consumption is the main part. The power consumption is mainly the energy consumed by compressed air, followed by the energy consumption of compressed oxygen. Therefore, production is usually 1 m3The electric energy (kW • h) consumed by oxygen is an index to measure the performance of oxygen generator. The energy consumption of compressor is related to compressed air volume, exhaust pressure and the efficiency of compressor. The key to improve the economical efficiency of oxygen production is to improve the management level and personnel quality. We should start from the following aspects:
1) reduce the operating pressure of the oxygen generator to reduce the power consumption of the air compressor. Therefore, the resistance of equipment and pipeline should be reduced as much as possible, and the pressure of the upper tower should be reduced; a certain main cooling liquid level should be maintained to make the main cooling work under the best heat transfer condition, so as to reduce the temperature difference of the main cooling, reduce the pressure of the lower tower; reduce the cold loss as much as possible.
2) improve the efficiency of the compressor. First of all, the management of intermediate cooler should be strengthened to make the air cool well.
3) increase air volume. The switching loss should be reduced and the leakage should be eliminated, so that more processing air can enter the tower to participate in the separation.
4) increase the output of oxygen and increase the extraction rate of oxygen. In adjustment, we should try our best to reduce the oxygen content in nitrogen.
5) extend the continuous operation cycle of the equipment and reduce the downtime and overhaul time. Therefore, it is necessary to strengthen the daily maintenance of the equipment and overhaul the equipment regularly. Ensure the removal effect of moisture and carbon dioxide.
6) absolutely avoid the leakage of low temperature liquid and low temperature gas in the tower. When heating the monomer equipment, the temperature should not be too high.
7) comprehensively utilize and produce a variety of products.
