【摘要】：供热系统是由热源、热能输送环节、热用户等几部分组成的一个复杂系统,为使热生产、输送、分配及使用都处于有序的状态,则需要在其各个环节进行节能,以提高供热系统的能源利用率。高等学校由于自身的独特的特点,节能的模式与其他建筑也有所区别,节能的意义更显得尤为重要。本文通过对中国医科大学新校园供暖系统的调查及分析,从供暖中热源、热能输送环节及热用户三个节能潜力的环节,结合现代控制技术、计算机技术、通讯技术、微电子技术对三个环节进行了研究,从而对实现高校供暖节能提供了有益的思路。本文在热源环节主要论述了锅炉燃烧系统的设计,将燃烧系统分为三个相互联系的子系统：链条炉的给煤调节系统、送风调节系统和引风调节系统。主要论述了变频技术、氧化锆测定含氧量技术、PID控制等技术在锅炉燃烧系统中的应用；在热源输送环节论述了管道直埋技术和换热站系统的设计及换热机组的控制策略；用户末端环节,通过在单体楼采暖管道入户处安装恒流量调节阀和市内供暖管道安装手动温控阀等措施有效的解决了水利失调问题。经过一个采暖季的调试运行,整个系统运行稳定,在满足用户需求的基础上,节约了大量水、电、煤资源。
[Abstract]:The heating system is a complex system composed of heat source, heat transfer link, heat user and so on. In order to make the heat production, transportation, distribution and use in an orderly state, it is necessary to save energy in every link. In order to improve the energy efficiency of the heating system. Because of its unique characteristics, the mode of energy conservation is different from other buildings, and the significance of energy conservation is more important. Based on the investigation and analysis of the new campus heating system of China Medical University, this paper combines modern control technology, computer technology and communication technology from three energy saving potential links of heating source, heat energy transmission link and heat user. The microelectronics technology has carried on the research to the three links, thus has provided the beneficial thought to realize the university heating energy saving. In this paper, the design of boiler combustion system is mainly discussed in the heat source link. The combustion system is divided into three interrelated subsystems: the coal supply regulation system of chain furnace, the air supply regulation system and the air intake regulation system. This paper mainly discusses the application of frequency conversion technology, zirconia determination of oxygen content technology and pid control in boiler combustion system, discusses the design of pipeline direct burying technology and heat transfer station system and the control strategy of heat exchanger unit in heat source transportation. By installing constant flow regulating valve in the heating pipe of single building and manual temperature control valve in the heating pipe of the city, the imbalance of water conservancy is effectively solved. After a heating season, the whole system runs stably and saves a lot of water, electricity and coal resources on the basis of meeting the needs of users.
