双路蒸汽凝结水并联平衡排放器
本专利技术属于蒸汽加热系统,尤其涉及一种双路蒸汽凝结水并联平衡排放器。
技术介绍
蒸汽加热设备凝结水的排放是系统运行的重要环节。工艺系统工程设计技术规定:对单台、单组加热设备而言,蒸汽放热后产生的凝结水进疏水阀排出;对单台加热设备安装两组换热器,如换热器容量不等则应根据换热器总数配装疏水阀。如图5、图6所示是现实工况中,单机台采用两组换热器并联排放凝结水的设备众多。其中,图6所示凝结水并联输出结构存在两个问题:①换热器1出水管路长度大于换热器2,排水管阻大于换热器2;②因凝结水在流出换热器时以汽液二相流状态进入排水管,换热器1排水管路在疏水过程中继续放热,凝结水的产生量会大于换热器2的凝结水量。上述两个问题的存在导致换热器2凝结水短路快速排放,造成换热器1的型腔内存水,导致系统放热不均匀影响总体放热效率。附图7所示,两组换热器出水管在间距中心经三通并联出水。此结构存在两个问题:①因凝结水流向对顶,直接影响“凝结水应顺流排放”的基本规律,造成排水不畅;②当两组换热器满足放热面积相等时,但因生产、制造、安装等存在不良因素则会导致某组排水不畅。此时将会造成两组换热器出水温度不等。若温度不等的两路凝结水在三通处汇流,同样导致较高温度的凝结水在三通出口处阻止较低温度的凝结水排放。鉴于出现上述问题,为此HG/T20570-95(中华人民共和国行业标准“工艺系统工程设计技术规定”)P5435.0.2的规定:“多台用汽设备不能共用一只疏水阀,以防短路排水”。若每组换热器安装一台疏水阀,不仅设备投入成本高,更主要的是多安装一台疏水阀,则会多增加 ...
