AI Technical Summary

Technical Problem

In the existing technology, the fluid flow in the vertical heat exchange tubes used for sand cooling is discontinuous, which leads to unstable heat removal. Furthermore, vacuum cooling and liquid nitrogen cooling methods have high requirements for equipment sealing or require large equipment.

Method used

Design a support device for the return inner tube of a vertical heat exchanger tube. Through the support device and auxiliary ring and other structures, keep the outer tube of the vertical cooling tube and the return inner tube parallel to ensure that the fluid flow cross section is consistent and that the heat is removed by fluid circulation.

Benefits of technology

It achieves continuity and stability of fluid flow, replacing cooling methods with high sealing requirements and large equipment, and improving the efficiency of heat removal.

Abstract

The utility model discloses a vertical heat exchange pipe backflow inner tube is with support device, support device is located between vertical cooling pipe outer tube and vertical cooling pipe backflow inner tube, the top of vertical cooling pipe outer tube is fixedly connected with the bottom of vertical cooling pipe outer tube and has the auxiliary ring, the upper surface of every auxiliary ring all is equipped with the installation mouth of equidistance arrangement, and support device and vertical cooling pipe backflow inner tube are fixed through welding, and the outer surface of support device and the inner wall of vertical cooling pipe outer tube are fixed through welding. The device is kept relative parallel by being provided with support device and makes vertical cooling pipe outer tube and vertical cooling pipe backflow inner tube, ensures that the fluid flow cross section size in pipe is identical, guarantees the continuity of fluid flow, realizes the heat of stable sand aggregate that takes away, replaces the cooling mode of traditional vacuum cooling, liquid nitrogen cooling, solves the disadvantage that such mode requires extremely high sealability to the bunker, and liquid nitrogen cooling needs extremely big liquid nitrogen equipment.
