The feasibility of the residual heat of the air compressor in the hospital oxygen system system Zou Qingbin (Xining si7, Qinghai Women's and Children's Hospital Equipment Division) will save a lot of energy by recovering waste heat from the air compressor, and reduce the emission of carbon dioxide or carbon monoxide in the air. The goal of energy conservation and emission reduction is of great benefit to the recycling of resources in the medical field. This paper discusses in detail the development history, special requirements and transformation process of hospital oxygen-making air compressor waste heat recovery technology and its application effect in practice. This technology will certainly produce good economic and social benefits in the hospital system.
The hospital's diagnosis and treatment technology has led to a variety of hospital gambling continually insulting the hospital's oxygen supply system.
The traditional method of oxygen supply is to directly adopt the oxygen bottle supply method, which wastes a lot of manpower and material resources and has safety risks in transportation and storage. After the development of technology, the supply mode has gradually changed to a central unified supply. The bed is taken from the central oxygen station for unified oxygen supply and oxygen is generated from the oxygen generator system and then transported to the oxygen end, that is, the various wards.
The continuity, safety and reliability of the oxygen supply system are improved. The shrinkage rate is also reduced. At the same time, the residual heat recovery technology of the air compressor of the residential oxygen generator system has also been greatly developed. The daily consumption of oxygen in a dry bed is more than one hundred bottles per bottle. Therefore, the residual heat recovery technology of the air compressor of the residential oxygen generator system can not only reduce the natural evaporation consumption but also can be fully automated for regular maintenance and cost saving. The hospital can comprehensively according to the specific requirements of its own oxygen use and the nature and planning of the hospital. On the basis of safety and economic factors, the air compressor recovery technology of the oxygen system is carried out. The heat source with higher quality is given to the engineer. The research direction is to study the advantages and disadvantages of the medical molecular sieve oxygen plant.
Through the new technology channels such as handheld video players, network downloads, interactive on-demand, etc. to watch TV programs, the consideration of ratings will no longer be the traditional TV ratings, but should be the comprehensive ratings of live broadcasts, on-demand broadcasts, etc. Corresponding methods of measurement and statistics also need to be updated. At the end of 2005, the Nielsen Media Market Research Corporation announced that it will adopt new TV ratings statistics methods in the United States to count consumers who watch TV through the Internet, mobile phones, lPd and other mobile communication devices. Although it seems that the implementation of such multimedia comprehensive ratings statistics for the China ratings survey market seems to be repayable, this does not mean that the window ratings will be the same. The common requirements of both parties will inevitably lead to the statistics of traditional ratings. Heat, domestic hot water, heating, etc.
On the one hand, the air heat recovery control system and the heat recovery exchange system are installed in the air compressor cooling system. The air compressor waste heat recovery scheme effectively solves the problem of energy consumption and environmental pollution. On the other hand, the inverter fan and water recording control are equipped at the same time. The system can go to the energy-saving prison to ensure the quality and longevity of the system.
2Special requirements for air compressors in hospital oxygen generator systems China has developed a technology for the recovery of oxygen compressors. The main obstacle in the research and design process is to clarify the special requirements of hospital oxygen compressors, because of the medical micro system. Oxygen machine and the air compressor equipped with the main machine have their own special requirements. The following is the summary and experience of the author from the work. The air compressor of a residential oxygen system should be able to adapt to the voltage. Due to the large fluctuations in the domestic power grid, especially during peak hours or summer ghost pressure, it can even drop to 167V. Oxygen generators cannot be copied according to the prototype (except for the prototype of the Chinese power grid). Can not meet the needs of pressure start. Therefore, the air compressor of the hospital oxygen system must be designed according to the characteristics of the voltage. If the rated power can be set, the output power must be designed according to 200W to achieve the voltage of 167V. start up.
And the application has changed. At present, the brand of children's TV show "I have no show" is passed: Ik Jing an advertising media company has been exported to Malaysia. This cross-media cooperation and the secondary sales of content distribution are the vane of the future development of Chinese children's programs.
