1、 1 哈尔滨市滨江小区供热管网及换热站设计 摘摘 要要 本工程为哈尔滨市滨江小区供热管网及换热站设计。小区内所有建筑物均为民用住 宅，四周为商业网点。小区占地面积约为 12 万，建筑面积约为 15 万。供暖热负荷 0.6810 7W，总循环水量 265.03t/h。 小区一次水供回水温 130/80，二次水供回水温 95/70。管网布置为闭式双 管异程式系统，枝状形式。采用补水泵定压方式，系统运行时，采用质调节调节方式， 以适应热负荷的变化。整个管道均为无补偿直埋敷设，所有管段采用预制保温管，保温 材料为聚氨酯，保护层为聚乙烯，由国家标准设计图集管道及设备保温98R418 确定 其保温层厚度，
2、通过水力计算确定管径。小区设一个地下换热站，内设 2 台型号 BR0.5 板式换热器，2 台型号为 IS200-150-400C 的热水循环泵（一备一用） ，2 台型号为 IS50-32-200C 的补水泵（一备一用） ，卧式直通除污器。整个网路由绘制的水压图可知 网路压力工况均满足技术要求。 关键词关键词： 热负荷；水压图 ；热力交换站 2 Abstract This project designed the heat supply pipe network and heatexchanging station of BinJiang district in Haerbing .All th
3、e buildings in this district are for residential use. Area covers approximately 120,000 and a building area of about 150,000 . Heating load 0.68 107W, with a total circulation stood 265.03t / h. Once water provides to return to water temperature 130 /80 , two waters provide to return to water temper
4、ature 95 /70 Adopt the way of patch water pump fix press.The pipe network is designed as seamless two-pipe system with tree-shaped. When the system is functioning, it adopt the quality flux regulates, in order to adapt to the changes of heat-load.The whole pipe is directly buried and self-compensated, the entire pipe sections are insulating constructive, (heat preservation material is polymer of ammonia and ester, protect layer is polyethylene).
