Abstract

The invention discloses a top anti-corrosion structure of a chimney. The chimney comprises a concrete outer barrel and a glass reinforced plastic inner barrel. The combined portion between the top of the concrete outer barrel and the glass reinforced plastic inner barrel is provided with a concrete platform. The portion, on the upper portion of the concrete platform, of the glass reinforced plastic inner barrel is provided with an annular skirt-shaped anti-corrosion structure layer. The skirt-shaped anti-corrosion structure layer extends to the concrete platform. Anti-corrosion structure layers are arranged on the concrete platform and the inner wall and upper end face of the portions, above the concrete platform, of the concrete outer barrel correspondingly. The skirt-shaped anti-corrosion structure layer and the anti-corrosion structure layers on the concrete platform and the inner wall and upper end face of the portions, above the concrete platform, of the concrete outer barrel form a whole. By means of the structure, corrosion to a concrete base body is comprehensively and completely eradicated from the top of the chimney, and corrosion resistance, safety and using reliability of chimney equipment are ensured.

Description

technical field [0001] The invention relates to a chimney, in particular to a top anticorrosion structure of the chimney. Background technique [0002] All kinds of chimneys in domestic large-scale metallurgy, electric power, chemical industry and other installations all adopt brick or concrete body structure. The sulfur-containing tail gas after boiler combustion is directly emptied, so the tail gas has a high temperature (>120°C), contains almost no moisture, and does not cause corrosion to the main body of the chimney; the tail gas of chemical and metallurgical equipment is in a high-temperature wet gas state, and passes through the chimney Directly emptying, the anti-corrosion treatment effect on the inner wall of the chimney has the disadvantages of difficult construction, long engineering period, short service life, and high maintenance costs. Along with people's emphasis on the living environment and the strict legislation of the national environmental protection ...
