螺旋板换热器
螺旋板式换热器是一种高效换热设备，适用汽-汽、汽-液、液-液，对液传热。它适用于化学、石油、溶剂、医药、食品、轻工、纺织、冶金、轧钢、焦化等行业。按结构形式可分为不可拆式(I型)螺旋板式及可拆式(Ⅱ型、Ⅲ型)螺旋板式换热器。
结构及性能:
本设备由两张卷制而成，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。
在壳体上的接管采用切向结构，局部阻力小，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。
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。
Ⅱ型可拆式螺旋板换热器结构原理与不可拆式换热器基本相同，但其中一个通道可拆开清洗，特别适用有粘性、有沉淀液体的热交换。
Ⅲ型可拆式螺旋板换热器结构原理与不可拆式换热器基本相同，但其两个通道可拆开清洗，适用范围较广。
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*大工作压力)。按材质可分为碳素钢和不锈钢。用户可根据实际工艺情况选用。
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。
