本科学生毕业设计 济南市尚品清河小区 集中供热热水网路设计 黑 龙 江 工 程 学 院 二○一一年六月 摘 要 本次设计为山东省济南市尚品清河小区集中供热设计，该小区共有建筑物87栋，设分为住宅、商服和综合楼，总供热面积为：600592m2回水温度80，二级网供水温度95，回水温度70。一级网采用通行地沟套管补偿器，二级网直埋敷设方形补偿器，所有支架均为固定支架。 间接连接供热因其热源补水率低，热网的压力工况和流量工况不受用户的影响，便于热网运行管理。在近年来已经成为流行的供热方式。本次设计为贴近实际也采用了间接连接供热，在小区设置了换热站， 关键词：集中供热；高区供热；换热站；补偿器；固定支架 Abstract The design for the shangpinqinghe district of Jinan city central heating design, this village of 87 buildings, building a house, shop and complex building is divided into, the total area is 600592 m2. heating. Design content mainly includes district heating and heat load of the community stand, hydraulic calculation pipeline layout, and other facilities. This design with the city level 1 network of district heating level to heat water supply temperature 130 net return water temperature, level 2 nets water supply temperature of 95, the return water temperature 70. Level 1 network using popular edible casing compensator, level 2 nets directly buried installation square compensator, all stents are fixed bracket. Indirect connection heating because of its heat source water rate is low, the network of working pressure and flow condition the influence of users by, easy to satisfy the operation management. In recent years have become popular heating way. This design for close to actual also used the indirect connection heating, in the residential area has a total station, heat five heat, five of which stand, stand the heat with high area. Heat transfer station design uses heat erchange unit in hot, water pump, the head of the horizontal are selected by meet high area the top of the heating, the design can deepen our through to the understanding of the actual project, exercise our drawing ability.
