Description

一种抽凝机组循环水供热系统
技术领域:
本实用新型涉及供热系统设备技术领域,尤其是指一种抽凝机组循环水供热系统。
背景技术:
    我国冬季采暖、城市集中供热、生产工艺集中供热等热水管网在很多情况下采用热电厂热电联供集中供热模式。火力发电厂抽凝机机组,发电热效率最大35%,大部分热量通过电厂凉水塔冷却水,将机组凝汽低品质的饱和蒸汽的汽化潜热带到大气中排出,从而浪费了这部分热量,而且影响能源利用的综合效率。
实用新型内容:
本实用新型专利的目的在于克服上述技术中存在的不足,提供一种适用范围广、投资和运行成本低的抽凝机组循环水供热系统,将废气回收进行用户采暖,从而达到节能减排的效果。 
本实用新型的目的是以如下方式实现的:一种抽凝机组循环水供热系统,包括锅炉和与锅炉连接的汽轮机,其特征在于:汽轮机排气管分成两路,一路通过汽轮机排气管与凝结泵相连,在通过循环系统连接冷却塔,另一路通过汽轮机排气管连接凝汽器的进口端,凝汽器上出口端通过循环泵连接采暖用户入口端,采暖用户的出口端连接在凝汽器下出口端上,凝汽器下出口端连接冷却塔。 
所述的凝汽器进口端前部设有泄压阀。 
所述的泄压阀为鸭嘴式喷淋阀。 
本实用新型的有益效果是:用于城区商业、办公、居民等采暖用热。汽轮机排出气体得到回收利用,引入采暖系统从而达到节约能源的效果,循环回路由开放式改为密闭式,回收废热,真正提高了热电联供集中供热系统综合能源利用效率。实现节能、减排等经济效益和社会效益,而且构设计合理,构思巧妙新颖,易于推广应用。 
附图说明:
图1是本实用新型结构示意图。 
具体实施方式:
参照图1,一种抽凝机组循环水供热系统,包括锅炉4和与锅炉4连接的汽轮机5,其特征在于:汽轮机5排气管分成两路,一路通过汽轮机5排气管与凝结泵3相连,在通过循环系统1连接冷却塔2,另一路通过汽轮机5排气管连接凝汽器6的进口端,凝汽器6上出口端通过循环泵7连接采暖用户8入口端,采暖用户8的出口端连接在凝汽器6下出口端上,凝汽器6下出口端连接冷却塔2。所述的凝汽器6进口端前部设有泄压阀。所述的泄压阀为鸭嘴式喷淋阀。工作时,汽轮机5排出的蒸汽通过汽轮机5排气管一部分进入凝结泵3通过循环系统1进入冷却塔2,另一部分蒸汽进入凝汽器6后吸热升温,然后通过循环泵7送入采暖用户8,采暖用户8为冷却装置的闭路循环,将原来65%以上浪费的热量收集后用于办公、商业、学校、居民等生活采暖。通过本实用新型使机组的热效率由35%提高到100%,采暖用户8放热后再循环回凝汽器6,最后从凝汽器6循环回冷却塔2。引入循环采暖系统从而达到节约能源的效果,循环回路由开放式改为密闭式,汽轮机5排出气体得到回收利用,真正提高了热电联供集中供热系统综合能源利用效率。实现节能、减排等经济效益和社会效益,而且构设计合理,构思巧妙新颖,易于推广应用。
