结构及性能

1、本设备由两张卷板卷制而成，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，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。

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。
5、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。
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和不锈钢。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。
Structure and performance
1, this equipment is composed of two roll plate coiling, formed two uniform spiral channel, two heat transfer medium can complete counter-current flow, greatly enhance the heat transfer effect, even if the two kinds of medium small temperature difference, also can achieve the ideal heat transfer effect.
2, take over on the shell structure of tangential, local resistance is small, uniform due to the curvature of the helical channel, the liquid flow within the device no big steering, the total resistance is small, so that can improve the design flow rate of high heat transfer capability.
3, I not detachable type spiral plate heat exchanger of helical channel transverse welding seal, thus has high sealing.
4, type II detachable spiral plate heat exchanger structure principle and not detachable heat exchanger basic same, but one of the channel with detachable cleaning, especially for viscosity and heat transfer of liquid precipitation.
5, III detachable spiral plate heat exchanger structure principle and not detachable heat exchanger basic same, but the two channels with detachable cleaning, wide application scope.
6, spiral plate heat exchanger can be divided by nominal pressure PN0.6, 1.0, 1.6, 2.5 MPa (refers to the single channel can withstand the maximum working pressure). According to the material can be divided into carbon steel and stainless steel. The user could be selected according to the practical process.
7, a single equipment cannot satisfy the use requirement, can use more than one combination, but when combined must meet the following requirements: parallel combination, serial combination, the equipment is the same as the channel spacing. Hybrid combination: a channel in parallel, series a channel.
