Embodiment Construction

[0016] For the specific technical scheme of the steel chimney inner tube anticorrosion device described in the present invention, refer to figure 2 :

[0017] First, derust the cylindrical surface of the steel inner cylinder, draw lines along the circumference of the inner wall of the chimney at an interval of 1200mm, and use an electric grinder to polish the drawn lines, with the drawn lines as the center, and the grinding width is not less than 100mm.

[0018] Secondly, weld the keel, find the horizontal reference line on the circumference of the ash accumulation platform, weld the first circle of keel along the horizontal reference line, and weld the entire circle of keel from bottom to top at intervals of 1200mm until all steel inner cylinders are evenly welded The upper keel, the carbon steel surface layer of the composite keel is welded with the steel inner cylinder.

[0019] Third, fill with SL200 high-temperature acid-resistant foam board, and fill SL200 high-tempera...

Abstract

The invention discloses an anticorrosion device for an inner cylinder of a steel chimney, comprising a steel inner cylinder, a keel, a high-temperature acidproof foam plate and a titanium plate. Each keel is horizontally arranged along the circumference of the steel inner cylinder and is fixed with the steel inner cylinder, a group of welding keels is arranged in the steel inner cylinder from topto bottom at intervals; the high temperature acidproof foam layer is filled between the keels on the wall of the steel inner cylinder, the inner side of the high temperature acidproof foam layer is fixed with the cylindrical titanium plate, and the titanium plate is fixed on the keel. The invention can solve the technical problem that the traditional steel chimney uses the steel as lining for theanticorrosion process.

Description

technical field [0001] The invention relates to an anti-corrosion technology for a chimney, in particular to an anti-corrosion modification technology for a steel chimney lined with carbon steel or sulfuric acid dew point steel. Background technique [0002] Anticorrosion of titanium metal plates is recognized internationally as one of the most reliable anticorrosion solutions for chimneys. For new chimneys, there has been successful experience in applying composite titanium alloy anticorrosion, and the technology is quite mature. How to use titanium alloy materials for anticorrosion on steel chimneys lined with carbon steel or sulfuric acid dew point steel is a very difficult subject, and there is no successful experience at home and abroad. Contents of the invention [0003] The object of the present invention is to provide a steel chimney inner tube anticorrosion device to solve the technical problem of anticorrosion treatment for traditional steel chimneys lined with s...
