AI Technical Summary

Technical Problem

In flue gas purification systems, soot buildup on heat exchange pipes reduces heat exchange efficiency and affects the normal operation of the electrostatic field.

Method used

Design a heat exchange tube cleaning device, which adopts a bracket and multiple scraper structures. The scrapers move along the axial direction of the heat exchange tube, and together with the cleaning brush and sealing door, achieve efficient removal of soot.

Benefits of technology

It simplifies the dust removal process, reduces the labor intensity of staff, extends the cleaning cycle of heat exchangers, improves heat exchange efficiency, and ensures the normal operation of the electrostatic field.

Abstract

The present application relates to flue gas purification device technical field, specifically disclose a kind of heat exchange tube ash removal device and flue gas purification system.The heat exchange tube ash removal device provided by the present application includes shell, heat exchange unit and ash removal structure.The heat exchange unit includes a plurality of heat exchange pipes installed in shell.Ash removal structure includes support and scraper, support is slidably connected on the inner wall of shell, scraper is all installed on support, when support slides along the inner wall of shell, scraper moves synchronously with support.Scraper is provided with through hole matched with heat exchange pipe, and all heat exchange pipes are installed in through hole, heat exchange pipe is close to or abutted on scraper.When support moves, support drives scraper to move along the axial direction of heat exchange pipe, scraper scrapes off the soot on the outer wall of heat exchange pipe at this time, to ensure that heat exchange pipe maintains preferable heat exchange efficiency.At least two scrapers are provided, not only make ash removal stroke shorten, but also make soot can be cleaned more cleanly.
