AI Technical Summary

Technical Problem

The existing soot blower sealing structure has a narrow sealing position and cannot be disassembled during use. It can only be handled during major maintenance. The use of wool felt structure leads to poor sealing effect and easy air leakage.

Method used

A soot blower sealing device is designed, adopting a split sealing structure, including a sealing shell, a gas nozzle, an inner sealing ring and an elastic compensator, which is fixed to the side of the soot blower body by screws, and an inner sealing ring and an elastic compensator made of polyimide material provide a tight shaft fit and sealing effect.

Benefits of technology

It realizes convenient installation and replacement of the sealing device, replaces the wool felt structure, provides a good sealing effect, avoids air leakage, and improves the service life of the device due to the use of wear-resistant and high-temperature-resistant polyimide materials.
