Chimney protection lining and manufacturing method thereof

Abstract

The invention provides a chimney protection lining and a manufacturing method thereof. The chimney protection lining comprises a plurality of arc glass steel interlayer tiles. The edges of the multiple glass steel interlayer tiles in the horizontal direction are mutually stacked to form cylinder sections in a surrounding manner. The edges of the multiple cylinder sections in the vertical directionare mutually stacked to form a cylindrical structure through assembling. The radius of each cylinder section is equal to the arc radius of each glass steel interlayer tile forming the cylinder sections. Vertical layer stacking lines between the adjacent cylinder sections are arranged in a staggered manner. According to the chimney protection lining obtained through the chimney protection lining and the manufacturing method thereof, the expanding treatment on a chimney inlet is not needed during actual construction, and the construction difficulty is lowered; the rigidity of tiles of interlayer structures is high, and the large-size cylinder sections can be efficiently obtained through assembling; and in addition, by adoption of the structure assembled in a chimney, field component production is not needed, field influences are avoided, and rapid installing is easily conducted.

Description

technical field [0001] The invention relates to the technical field of chimney anticorrosion, in particular to a chimney protective inner lining which can be used for flue gas discharge equipment such as coal-fired power plants and a manufacturing method thereof. Background technique [0002] In the industrial production of enterprises such as coal-fired power plants, the chimney is a structure that discharges various exhaust gases and smoke. Traditional chimneys are mostly reinforced concrete structures or steel structures. In recent years, in order to adapt to increasingly stringent environmental protection regulations, many thermal power plants have adopted wet desulfurization technology to reduce SO 2 emissions. The flue gas temperature before wet desulfurization is high (generally over 125°C), and the water content is very low, which generally does not have a large corrosion effect on the chimney. However, after wet desulfurization treatment, the temperature range of...

AI Technical Summary

Problems solved by technology

These existing schemes need to install glass steel plates one by one along the inner wall of the chimney, the construction area and the vertical height of the construction are large, the construction quality is difficult to be guaranteed, and it is also difficult to check construction defects

Compared with the anti-corrosion effect and construction efficiency of the formed FRP chimney inner cylinder, there are great shortcomings. However, the old chimney cannot be protected by the existing formed FRP chimney inner cylinder technology, which is a very contradictory problem
