卫生级双管板换热器

工作方式
管程物料通过电抛光处理的无缝钢管束内进行流动，壳程介质在相反的方向通过 管外流动，换热管束的末端采用双管板连接，并且作为渗漏检测点，避免管程物 料和壳程介质双向交叉污染，确保了药液的洁净。
Working principle
Tube material flow through the seamless steel tube electric polishing processing within the beam.Shell cheng medium flow in the opposite direction through the outer pipe,heat exchange tube bundle bottom USES tube plate tighten,some as a leakagemonitoring stations,prevent Two- way cross contamination bettwen the tube mate rial and Shell cheng medium.To insure the cleaning of the solution.

双管板换热器型式
ZZ系列双管板换热器有两种，直管式双管板换热器(ZZA型)和U型双管板换热器 (ZZB型)，管束端口采用全自动焊接，外壳体可根据客户的要求带保温或不带保 温。直管式双管板换热器采用异径快装接口，有效避免了换热器与管道连接处的 药液滞留，实现了真正的全排空设计。U型双管板换热器采用U型换热器，物料从 底壳最低点出液，避免液体滞留。
The type of double tube heat exchanger
In generally have two Types.Fixed tube heat exchanger and "U" Pipe heat exchanger.Fixed tueb heat exchanger adopt the different diameter fast loading interface.Effectively avoid Liquid stop at the cinnecting of heat exchange and pipeline,it can achieve the Whole emptying preset.And the "U" Pipe heat exchanger use the U type heat exchanger tube.produce the liquid from the rock bottom of the bottom box.Avoid

设备应用
