Segmented self-standing anti-corrosion smoke exhaust inner sleeve for steel inner barrel chimney and construction method of segmented self-standing anti-corrosion smoke exhaust inner sleeve

Abstract

The invention discloses a segmented self-standing anti-corrosion smoke exhaust inner sleeve for a steel inner barrel chimney. The segmented self-standing anti-corrosion smoke exhaust inner sleeve comprises single inner sleeve segments 1 and at least two layers of segmented supporting components 2. Each layer of segmented supporting component 2 is fixedly connected to the inner wall of an outer chimney inner barrel 3, the single inner sleeve segments 1 are vertically put on supporting bottom plates 4 of the segmented supporting components 2, segmented inner sleeves 5 are formed by the single inner sleeve segments 1 put between the segmented supporting components 2, and the height of the segmented inner sleeves 5 and the height between the segmented supporting components 2 are basically consistent. A structure and a construction method of the segmented self-standing anti-corrosion smoke exhaust inner sleeve are creatively provided, an independent inner sleeve unit is formed by one segmented supporting component and one segmented inner sleeve, the whole inner sleeve is composed of the multiple inner sleeve units, the units cannot be affected or intervened, the scheme is simple in structure, low in cost and easy to construct, a large amount of time can be saved, and a large amount of invested cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of chimney anticorrosion, and in particular relates to a segmented self-supporting anti-corrosion and smoke-exhaust inner sleeve for steel inner-tube chimneys and a construction method for the anti-corrosion and smoke-exhaust inner sleeve. Background technique [0002] In my country's energy structure, the burning of coal accounts for more than 70%, resulting in several severe acid rain areas in my country's economically developed areas, seriously destroying the natural environment we depend on for survival. In order to solve this environmental problem, my country has implemented coal-fired power plant flue gas desulfurization nationwide since 2002, most of which are wet flue gas desulfurization processes represented by limestone-gypsum method, and the general desulfurization efficiency is average. Can reach more than 95%. Due to the addition of the wet flue gas desulfurization process, the flue gas discharg...

AI Technical Summary

Problems solved by technology

In addition, since all segmented inner sleeves need to be stacked together, complex socket structures must be used in order to connect reliably, and complex clamp structures are used between each segment of the inner tube, and the construction process and The connection structure is complex, and there are many possible failure links
