AI Technical Summary

Technical Problem

The existing anti-corrosion structure for the inner wall of chimney lacks a cleaning mechanism when the flue gas condensates to form acid liquid, causing the acid liquid to flow down the inner wall, seriously corrode the flange connection, and shorten the service life of the chimney.

Method used

A anti-corrosion structure of the inner wall of the chimney including a rotating assembly, a scraper, a guide channel and a conveying pipe is designed. The scraper is driven to scrape the acid liquid from the inner wall of the chimney through the rotating assembly, and the scraped acid liquid is introduced into the collection box through the guide channel and the conveying pipe for collection.

Benefits of technology

It effectively reduces the corrosion rate of the inner wall of the chimney, extends the service life of the chimney, and prevents acid from being discharged directly into the environment, reducing pollution to the surrounding environment.

Abstract

The inner wall anti-corrosion structure comprises an installation base, the outer wall of the installation base is fixedly connected with a second connecting flange, the upper surface of the installation base is movably connected with a chimney body, the outer wall of the chimney body is fixedly connected with a first connecting flange, and the first connecting flange and the second connecting flange are each provided with an installation hole. The upper surface of the chimney body is fixedly connected with a supporting rod, the upper end of the supporting rod is fixedly connected with a bearing plate, the bearing plate is provided with a rotating assembly, the side surface of the rotating assembly is fixedly connected with a connecting frame, the side surface of the connecting frame is fixedly connected with a scraper, and the scraper is slidably connected with the inner wall of the chimney body. The inner wall of the mounting base is fixedly connected with the flow guide channel, the flow guide channel is located below the scraper, and through the components, dewed acid liquor in smoke can be effectively scraped and is prevented from staying on the inner wall of the chimney for a long time, so that the corrosion speed of the inner wall of the chimney is reduced.
