摘要
城镇供热系统的节能改造是建筑节能的重要组成部分,其节能改造符合国家节能减排政策,是节能减排工作的重点之一。为有效解决目前集中供热管网存在的易腐蚀、使用寿命短、"跑、冒、滴、漏"严重、热损失大、水质差等问题,对供热系统节能改造中使用的供热管道提出了更高的要求。该项目是国内首次系统地对预制保温塑料管道设计、生产、应用开展研究,对集中供热预制保温塑料管道在我国大面积推广应用,起到促进和技术保障作用,研发的技术和产品可有效解决传统集中供热管网的易腐蚀、寿命短、热损失大等常见问题,提高了城镇供热管网建设水平、减少管网维修量、提高劳动生产率、降低供热管网漏损率,对保障城市供热安全和供热节能,促进住房和城乡建设领域节能减排工作具有重要意义。
The energy-saving transformation of district heating system is an important part of building energy conservation, and it is also one of the key areas of the national policy on energy conservation and emission reduction .In order to solve the problems of current steel pipe network such as corrosion, short service life, serious leakage, heat loss and polluted water due to corrosion of the district heating pipe network, higher requirements have been put forward for the heating pipe in the energy-saving transformation of the district heating system. In this project, a kind of pre-insulated plastic pipe is developed, which consists of outer protective pipe, irmer pipe support, insulating layer and service pipe. Also related engineering design, production technology, perlbrmance test, construction and application technology of pre-insulated plastic pipeline for district heating are studied systematically for the first time in China, which would play positive roles in energy-saving transformation of district heating system as well as energy conservation and emissions reduction all over the country.
