螺旋板式換熱器的結(jié)構(gòu)特點(diǎn):
1、熱效率高
螺旋板式換熱器能使兩種熱交換流體處于較低的流速下,激起湍流,從而提高傳熱效率。
2、體積小、占地面積少
螺旋板式換熱器占地面積為列管換熱器的30%左右。
3、組裝方便
當(dāng)工藝條件和產(chǎn)量變化時(shí),要增減板片數(shù)量或改變板片組裝流程通道形式。
4、耗能低
螺旋板式換熱器主要由不銹鋼或鈦合金壓制的傳熱片、密封膠墊、夾緊螺栓和壓緊板整機(jī)框架等零部件組成。
5、熱損失小
螺旋板式換熱器由于板片周圍邊暴露在空氣中,不需要采用保溫層。
Structural features of spiral plate heat exchanger:
1, high thermal efficiency
The spiral plate heat exchanger enables the two heat exchange fluids to flow at a lower flow rate, stimulating turbulence, thereby improving heat transfer efficiency.
2, small size, less floor space
The spiral plate heat exchanger covers an area of about 30% of the heat exchanger of the tube.
3, easy to assemble
When the process conditions and production vary, the number of plates is increased or decreased or the channel form of the plate assembly process is changed.
4, low energy consumption
The spiral plate heat exchanger is mainly composed of a heat transfer sheet pressed by stainless steel or titanium alloy, a sealing rubber pad, a clamping bolt and a whole frame of the pressing plate.
5, small heat loss
The spiral plate heat exchanger does not require an insulating layer because the periphery of the plate is exposed to the air.
