working method
The material in the tube side flows through the seamless steel pipe bundle processed by electric polishing, while the medium in the shell side flows outside the tube in the opposite direction. The end of the heat exchange tube bundle is connected by a double tube plate and serves as a leakage detection point to avoid bidirectional cross contamination between the material in the tube side and the medium in the shell side, ensuring the cleanliness of the liquid medicine.
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.

Double tube plate heat exchanger type
There are two types of ZZ series double tube plate heat exchangers: straight tube double tube plate heat exchanger (ZZA type) and U-shaped double tube plate heat exchanger (ZZB type). The tube bundle ports are fully automatically welded, and the outer shell can be insulated or not according to customer requirements. The straight tube double tube plate heat exchanger adopts a reducing quick installation interface, effectively avoiding the retention of liquid at the connection between the heat exchanger and the pipeline, and achieving a true full emptying design. The U-shaped double tube plate heat exchanger adopts a U-shaped heat exchanger, and the material is discharged from the lowest point of the bottom shell to avoid liquid retention.
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
