Example Embodiment

[0015] Example: Referring to the accompanying drawings, firstly, the upper and lower end faces of the foamed glass bricks will be slotted (or required to provide upper and lower end face slotted bricks), first, on the inner surface of the chimney steel inner cylinder 1, apply anti-corrosion primer 2, and then apply the anti-corrosion primer 2 on the primer surface. Scrape the silicone rubber 3, and coat the silicone rubber on the sticking surface of the foam glass brick 4, press it on the inner surface of the chimney, and paste it into a circle one by one, then bend the temperature-resistant and anti-corrosion plastic strip or stainless steel strip with a height greater than the depth of the groove to embed it. Put it in the groove on the top surface of the paste brick, apply the adhesive, continue to paste the upper anti-corrosion brick, and so on until the paste is completed.

[0016] The sticking structure and method of the invention can be used not only for new chimneys wit...

Abstract

The invention relates to the improvement of pasting anti-corrosion layers on chimneys, and is characterized in that the anti-corrosion bricks pasted into a circle are provided with elastic support rings that generate radial outward pressure. Through the arching pressure generated by the hardness and elasticity of the embedded strip or ring, the pressure on the wall of the pasted brick is caused, so that the pasted brick still maintains a constant compressive stress after manual pasting until the adhesive is completely cured (cured in a state of compressive stress), thereby enhancing the It improves the bonding fastness of the pasted anti-corrosion brick and the inner wall of the chimney and the compactness of the adhesive, improves the anti-dropping property of the pasted brick and the impermeability of the adhesive, thereby overcoming the stickiness caused by curing under no compressive stress after pasting in the prior art. The quality of the knot is not high and the fit is not tight, which effectively ensures the quality of the paste, can ensure a long service life, and does not reduce the speed of the original paste. At the same time, the existence of the support ring makes the pasted bricks form an integral ring, and the circular arch function also effectively prevents the falling off even if there are a few bricks that are not firmly pasted.

Description

technical field [0001] The present invention relates to the improvement of pasted anticorrosion layer for chimneys, in particular to a kind of pasted anticorrosion layer for chimneys with full adhesive layer and almost no gaps, and pasted bricks are firmly combined with the inner wall surface of the chimney and are not easy to fall off. Background technique [0002] Chimneys (such as thermal power plants, chemical plants, oil refineries, etc.) usually have two basic structures, one is a full concrete chimney, and the other is a composite chimney with a concrete cylinder outer support and a steel inner cylinder. In order to adapt to wet desulfurization, and And reduce the huge investment of hot air drying device (GGH), usually paste the anti-corrosion layer on the inner wall of the chimney, such as foam glass (vitrified ceramic) bricks, to enhance the anti-corrosion of the inner wall of the chimney passing through the smoke, and protect the chimney from the corrosion of the fl...
