AI Technical Summary

Technical Problem

Existing online shell-and-tube heaters are prone to leakage after a period of use, and their heating efficiency and corrosion resistance are insufficient, making them unable to meet the heating requirements of high-pressure and corrosive liquids.

Method used

The shell, top seat, and pressure ring are made of corrosion-resistant materials and are fastened with bolts to enhance sealing. The inner tube and heating wire are made of corrosion-resistant insulating materials, and a dry-burning protection device is designed to prevent leakage and dry burning, thereby improving heating efficiency.

Benefits of technology

It achieves long-term leak-free operation under high pressure and corrosive liquid environments, and has high heating efficiency and anti-dry-burning protection function.
