螺旋板式换热器是一种高效换热设备,适用于汽—汽、汽—液、液—液,对流传热,废热回收,也可用于蒸汽冷凝和液体蒸发传热。它适用于石油、化工、冶金、溶剂、医药、食品、轻工、轧钢、焦化、酒精、造纸、供热等行业。按结构形式可分为不可拆式(I型)和可拆式(II型、III型)螺旋板式换热器。
结构及性能:
1、本设备由两张钢板卷制而成,形成了两个均匀的螺旋通道,两种传热介质可进行全逆流流动,大大增强了换热效果,即使两种小温差介质,也能达到理想的换热效果。
2、在壳体上的接管采用切向结构,由于螺旋通道的曲率是均匀的,液体在设备内流动没有大的转向,总的阻力小,因而可提高设计流速使之具备较高的传热能力。
3、I型不可拆式螺旋板式换热器螺旋通道的端面采用焊接密封,因而具有较高的密封性。
4、II型可拆式螺旋板式换热器结构原理与不可拆式换热器基本相同,但其中一个或者两个通道可拆开清洗,可拆通道用法兰及平盖封堵,特别适用有粘性、有沉淀液体的热交换。
5、III型可拆式螺旋板式换热器结构原理与II型可拆式螺旋板式换热器基本相同,但其可拆通道由法兰及封头连接,可拆通道贯通,可拆开清洗,适用范围较广,可用于冷凝和蒸发。
6、螺旋板式换热器按公称压力可分为PN0.6、1.0、1.6、2.5MPa(系指单通道能承受的最大工作压力)。按材质可分为碳素钢、不锈钢和钛材。用户可根据实际工艺情况选用。
7、单台设备不能满足使用要求时,可以多台组合使用,但组合时必须符合下列规定:并联组合、串联组合,设备和通道间距相同。混合组合:一个通道并联,一个通道串联。
