AI Technical Summary

Technical Problem

In the initial stage of startup, the existing heat exchanger prevents the tube-side fluid from directly impacting the tubes. As a result, the fluid rushes towards the tube sheet, causing a large impact force that affects the strength of the connection between the heat exchange tubes and the tube sheet, posing a risk of cracking and failure.

Method used

A shock-resistant heat exchanger tube box is designed. Through the medium flow hole structure formed by the upper and lower shock plates, part of the tube-side fluid enters the sealed chamber through the medium flow hole, reducing the flow rate to the tube sheet, reducing the impact force during the initial start-up, and providing heat preservation effect after stable operation.

Benefits of technology

It reduces the impact force on the tube sheet during the initial start-up of the heat exchanger, reduces the risk of cracking at the connection between the heat exchange tubes and the tube sheet, and improves heat exchange efficiency and corrosion resistance, while facilitating maintenance.

Abstract

The utility model discloses a kind of anti-impact heat exchanger tube box and heat exchanger, belong to heat exchanger technical field, including tube sheet, head, tube hole is arranged on tube sheet, and sealing chamber is formed between tube sheet and head;Sealing chamber is arranged in inlet connector, and inlet connector one end is connected with anti-impact mechanism;Anti-impact mechanism includes upper anti-impact plate, lower anti-impact plate, and upper anti-impact plate bottom end periphery is pressed on lower anti-impact plate, and lower anti-impact plate bottom end periphery is pressed on tube sheet;First flow cavity is arranged between upper anti-impact plate, lower anti-impact plate, and flow-through hole is arranged on lower anti-impact plate;Medium flow-through hole is arranged on upper anti-impact plate.The utility model tube box is as the tube medium inlet tube box, at the beginning of heat exchanger start, part of tube medium flows into sealing chamber by medium flow-through hole, to make the flow of tube medium flowing to tube sheet through flow-through hole on lower anti-impact plate reduce, and then reduce the impact force to tube sheet, to reduce the risk of heat exchange tube and tube sheet connection place cracking failure.
