Problems solved by technology

[0002] Brick lining Most chimney brick linings are provided with expansion joints on the upper part of the corbels. The expansion joints are very difficult to deal with in the later anti-corrosion treatment process, and defects such as leakage often occur. Therefore, a reliable treatment method is needed to effectively solve the problem. The closure, expansion and anti-corrosion of the expansion joints of the chimney inner tube, to avoid leakage after anti-corrosion
However, there is currently no such structure that works

Embodiment

[0013] Such as figure 1 As shown, it is a sectional view of a brick-lined chimney expansion joint sealing and anti-corrosion structure provided by the present invention, which is applied on the chimney outer cylinder 1, and between the chimney outer cylinder 1 and the chimney brick lining 3 is a sealed air or heat insulation layer 2. According to the actual matrix condition, the brick 12 can also be added later. The purpose of adding this brick is to adjust the size of the expansion joint reserved under the drip plate 9. The joint should be less than 80mm. Sealing material for chimney gaps13. After cleaning or sandblasting of all brick lining surfaces, paint epoxy primer (such as Henkel's PENNTROWEL EPOEXY primer) 4, fill the reserved seam under the drip board 9 with compressible rock wool 11, and use elastic glue Adhesive (such as Henkel PENNGUARD ADHESIVE MEMBRANE) 5 coated surface and brick surface seal. The sealing film 8 is fixed on the facade of the upper brick and the...

Abstract

The invention relates to a sealing corrosion-resistant structure of an expansion joint of a brick lining chimney, which comprises rock wool. The structure is characterized in that the rock wool is filled into the sealing expansion joint with elastic adhesive; an isolating membrane with high intensity, high temperature resistance, and good corrosion resistance and good ageing resistance is taken as a sealing membrane; the sealing membrane is fixed on the upper-layer and lower-layer brick lining with bolts and press plates; the surface of the brick lining is evenly covered with corrosion-resistant and ageing-resistant adhesive to be formed into the sealing structure; the outer surface of the sealing membrane is protected by foaming bricks; and the foaming bricks are glued to the outer sides of the sealing membrane and the brick lining with priming paint and the adhesive to be formed into a protection layer. The sealing corrosion-resistant structure has the advantages of corrosion resistance, ageing resistance, wide expansion bound, safety and reliability, good sealing capability, and good integrity.

Description

technical field [0001] The invention relates to a brick-lined chimney expansion joint sealing and anticorrosion structure, which is used for sealing and anticorrosion of the expansion joints of the brick-lined chimney in industries such as thermal power plants, chemical industry and metallurgy. Background technique [0002] Brick lining Most chimney brick linings are provided with expansion joints on the upper part of the corbels. The expansion joints are very difficult to deal with in the later anti-corrosion treatment process, and defects such as leakage often occur. Therefore, a reliable treatment method is needed to effectively solve the problem. The closure, expansion and anti-corrosion of the expansion joints of the chimney inner tube can avoid leakage after anti-corrosion. However, there is no effective similar structure at present. Contents of the invention [0003] The purpose of the present invention is to provide a safe, reliable and convenient construction exp...
