Membrane separation oxygen-rich combustion technology.
Oxygen-rich, widely used in all kinds of oil, gas, coal-fired kilns (glass, cement, ceramics), industrial boilers, heating furnaces, incinerators, heat medium furnaces, hot blast furnaces, smelting furnaces and other combustion, energy saving and environmental protection; In the fields of catalytic cracking, wastewater treatment, engine, oxygen-rich (coal) gas, various oxidation reactions, fermentation and other fields, oxygen-enrichment technology has also been applied to achieve good economic benefits. According to the scientific data research and the thermal efficiency of the customer's kiln itself, the use of oxygen-rich energy-saving technology can achieve certain benefits of increasing production and reducing consumption, improving the quality of products, extending the furnace age, and eliminating exhaust gas pollution.
Technologically advanced membrane oxygen enrichment system.
At present, we have successfully applied the membrane oxygen-rich combustion energy-saving technology to non-ferrous metal smelting, glass pool furnace energy-saving, chemical iron furnace and casting furnace energy-saving, etc., and have achieved the effect of improving product quality, saving energy and improving the environment, and the energy-saving rate is generally 10%-15%. The plate membrane oxygen production system provided by Zhongneng Xingke is the world's most advanced membrane oxygen enrichment system, which is a standard industrial modular device, which can produce oxygen-enriched gas when connected to the power supply. This technical system has the leading characteristics of competition in the following aspects:
Patented process technology for oxygen enrichment extraction.
Patented technology for plate membrane modules.
Membrane-to-membrane separation design software.
Three-dimensional design. Practical and user-friendly design.
The selection of excellent components to ensure the reliability and stability of the equipment.
Joint unit of the National Thermal Engineering Laboratory Project.
It is the best way to achieve energy saving, environmental protection and social benefits.
Overview of technical features:
The comprehensive energy-saving effect is more than 20%-60%.
The cost of energy saving in the project ranges from hundreds of thousands to tens of millions.
It is suitable for all kinds of industrial kilns with combustion systems.

The use of polymer selective gas separation membrane to separate the air, so as to obtain oxygen-rich air with oxygen content of 28 for industrial combustion, is a good energy-saving effect, high economic benefits, can be less environmental pollution of efficient combustion technology. However, this new combustion technology has not been studied and applied in the most widely used power machinery internal combustion engine. Through the analysis and research of the principle of gas membrane separation and the combustion process of internal combustion engines, this paper demonstrates the feasibility of the application of oxy-fuel combustion technology in internal combustion engine combustion and its advantages in saving energy, reducing sewage discharge and improving performance of internal combustion engines.

According to the statistics and estimation of the example of membrane oxygen enrichment technology in domestic industrial application, taking the use of industrial steam boiler as an example, the economic efficiency of energy saving is expected
1. The oil consumption or coal consumption is estimated according to the full load output of the boiler and the annual (according to 300 days) operation, and the % energy saving rate is estimated according to the average estimate of actual application.
3. The oil price is estimated at 1,500 yuan, the calorific value of coal is 3,500-4,000 kcal, and the coal price is estimated at 200 yuan.
According to the current market operation, the one-time investment of the membrane oxygen enrichment complete set of equipment, deducting the operating costs (power consumption), can recover the investment in the current year, and in most cases the investment can be recovered in about 6 months, and the service life of the device is ten years (including 2 years for the membrane element). Therefore, the economic benefits of adopting this technology are considerable.
