Description

等长螺旋缠绕列管
技术领域
本发明涉及一种等长螺旋缠绕列管,主要涉及一种化工、食品制药过程的换热器,适用于有机物料的冷凝,利用蒸汽加热物料或水。
背景技术
现有的换热器多是管壳式换热器,换热管一般为直管或螺旋缠绕列管式,前者在相同体积内换热体积较小,耗能大,一般需要理论换热量的3-5倍的耗能才能够达到效果,无法保证加热和冷凝效果,故换热效率低,造成能源的巨大浪费,且其为直管换热,由于没有弯曲,导致其在气、液换热时气体容易短路,造成溶媒回收率极低,无法完成回收功能;后者虽改进了前者的换热效率低,但由于换热管束存在长短不一,导致加热不均匀,使换热不彻底,尤其在溶媒回收领域,由于其部分短管的换热不太彻底,导致溶媒回收率下降,对有些要求较高的物料不适用,但其螺旋缠绕方式能够使设备在工作时,管程内的物料形成紊流,增加换热强度。
发明内容
本发明的目的在于克服上述不足,提供一种换热效率高、换热均匀、不易变形的等长螺旋缠绕列管。
本发明的目的是这样实现的:一种等长螺旋缠绕列管,包括换热管组,所述换热管组由三根等长的换热管通过螺旋缠绕的方式形成,并且三根换热管缠绕后的截面呈等边三角形。
所述换热管为薄壁细长金属管,其金属管外壁有螺纹线。
与现有技术相比,本发明具有以下有益效果:
1、使换热管组的单位体积内换热面积加大,提高了能源利用率;
2、等长换热管使换热器换热均匀,提高了换热稳定性。
附图说明
图1为本发明的结构示意图。
图2为图1的AA剖视图。
其中:
换热管组1、换热管2。
具体实施方式
参见图1—图2,本发明涉及一种等长螺旋缠绕列管,包括换热管组1,所述换热管组1由三根等长的换热管2通过螺旋缠绕的方式形成,并且三根换热管2缠绕后的截面呈等边三角形,换热管2为一种薄壁细长金属管,其金属管外壁可有螺纹线。
