Seal.This sealing structure shell side pressure is bigger, and the sealing effect between tube sheet and inverse flange is better, has certain self-sealing
Property.
For the dismoutability for realizing tube bank complicated loop structure is arranged at tube sheet often to press in existing double pipe heat exchanger
Filling out letter or use seal with elastometic washer between tight tube sheet and shell, and it is higher to medium requirements to fill out function sealing, is not suitable for easily waving
Occasions, the seal with elastometic washer such as hair, inflammable, explosive, toxic again have certain limitations medium temperature and pressure.When encounter high temperature difference,
When explosive, toxic operating condition, existing equipment often because the defect of sealing structure shortens service life of equipment, causes production cost
Waste.
For this purpose, providing a kind of U-shaped double pipe heat exchanger, which includes bobbin carriage, shell, tube bank, tube bank
Including tube sheet, U-shaped heat exchanger tube；Shell is two mutually independent housing parts, one end of two housing parts and a side of end plate
Face is fixed, and another side end face of end plate is connected with skull, and heat exchanger tube via hole corresponding with two housing parts positions is provided on end plate,
The both ends of U heat exchange and the tube sheet for being located at two housing parts other ends connect and compose tube bank, and tube bank elbow part is located at
The heat exchanger tube via hole that skull is interior, two straight-tube portions pass through on end plate is located in two housing parts, each housing parts one end configuration
One bobbin carriage is respectively equipped with shell side inlet and shell-side outlet on two housing parts, be respectively equipped on two bobbin carriages tube-side inlet and
Tube side outlet；Bobbin carriage outer ring is equipped with channel flange, and the housing parts other end is connected with inverse flange, channel flange, inverse flange, pipe
Plate is connected with, and sealing ring is equipped between channel flange and inverse flange, sealing ring also is provided between inverse flange and tube sheet.
The dismoutability and self-sealing of Rational structure realization equipment, shell side pressure are selected in the U-shaped double pipe heat exchanger design
Bigger, the sealing effect between tube sheet and inverse flange is better.Using housing parts structure, it can cover more and be used in series, tube sheet and anti-
To the connection structure of flange, the scope of application is wider, while realizing the Whole-dismountable of tube bank, easy to clean and replacement tube bank,
It is compact-sized, securely and reliably, it can satisfy the requirement of Various Complex technique.
