Abstract
The utility model discloses a composite anticorrosive structure for the inner wall of a chimney. The composite anticorrosive structure comprises a surface treating agent bottom layer combined with the inner wall of the chimney, a glass block intermediate layer cemented through daub, and a fluorocarbon rubber surface layer on the intermediate layer. Because light boric glass blocks are adopted, the specific gravity of which is 170 kg/<m> [3] and only one dozenth of currently used acidproof bricks, and therefore the dead weight of the chimney is greatly reduced; siliceous elastic daub is used for connecting the light boric glass blocks, which is heat resistant and anti-corrosive, the percentage elongation of which can reach 170 percent, and which can play the role of compensating the cold and hot stress of the inner wall of the chimney; a layer of fluorocarbon rubber coating is scratched on the surface of the light boric glass blocks, so that the protection structure is a whole; the anticorrosive structure composed of the three layers can effectively play the function of preventing flue gas from eroding and corroding the wall of the chimney, and can prolong the service life of the chimney.
Description
Technical field
The utility model belongs to the chimney wall structure, is specifically related to a kind of inwall composite anti-corrosive structure of industrial chimney.
Background technology
Industrial chimney is generally built by concrete, steel, and its inwall need carry out corrosion-resistant thermal insulation.Method in common is inner refractory brick, acidproof brick and the swabbing built.There is following shortcoming in these common methods: 1. brickwork joint easy to leak, corrosion resistance are poor; 2. acidproof brick is than great, and integral lining weight is many, has increased the construction load; 3. the expansion that difference variation is caused is not resisted with contraction, and environmental suitability is relatively poor.
Inner wall of stack is anticorrosion to face a following difficult problem: 1. the inner wall of stack variations in temperature is bigger, and opposing is expanded and contraction is had relatively high expectations to the inwall protective layer; 2. chimney inside corrosion monitoring difficulty is big, and maintenance at ordinary times is inconvenient, and claimed layer reliability service for a long time uses; 3. chimney is a tall and slender structure, and the stressing conditions complexity in case be subjected to corrosion failure, can only be reconstructed; 4. it is very high to adopt corrosion resistant alloy to make the chimney cost; 5. common coating and acidproof brick reliability can not be guaranteed.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of inner wall of stack composite anti-corrosive structure is provided.Adopt the chimney of this structure have favorable anti-corrosion effect, from the advantage of heavy and light, good environmental adaptability.
Realize that the technical scheme that the utility model purpose adopts is: inner wall of stack composite anti-corrosive structure comprises on the surface conditioning agent bottom that combines with inner wall of stack, the bottom with the glass blocks intermediate layer of clay bonding and the fluorine-containing rubber mass surface layer on the intermediate layer.
In the described technical scheme, bottom is used for the chimney wall strong bonded with steel, concrete, refractory material, can add heat resistance fiber in the bottom to gain in strength, perhaps sticking glass fabric between bottom and the glass blocks intermediate layer that bonds with clay.The intermediate layer can be played and be isolated the corrosive medium effect, preferably adopts siliceous elastic cement bonding to contain the borosilicate glass piece.Facing surface has hydrophobic and viscosity not.This safeguard structure is fit to newly-built chimney and the protection of old chimney.
The utility model will be handled the inner wall of stack surface when construction.Concrete is coated the sealing primer, and existing good bond strength has been isolated the corrosion composition infiltration again.The steel inner wall of stack is adopted spray quartz sand or Shot Blasting, thoroughly remove descale, iron rust, greasy dirt and dust, and make the surface produce 70 μ m surface roughnesses, improve primer adhesive force.
The utility model anticorrosion structure thickness is generally less than 55mm, and the flue gas actual internal area is influenced less than 1.7%.The every weight per square meter of corrosion protective covering does not constitute influence less than 14kg to the chimney raft load-bearing.
The utility model is owing to adopt lightweight boron-containing glass piece, and its proportion is 170kg/m
3, only be 1/tens of the present acidproof brick that uses, the deadweight that has alleviated chimney greatly; What connect lightweight boron-containing glass piece is siliceous elastic cement, and the long rate of not only heat-and corrosion-resistant, and Shen reaches 170%, can play the cold and hot STRESS VARIATION of compensation inner wall of stack, and environmental suitability significantly improves; Containing fluororubber coating at lightweight boron-containing glass brick surface blade coating one deck makes the protection structure more complete, more safe and reliable; Can effectively play the erosion-corrosion effect of flue gas that prevent by three layers of anticorrosion structure of forming, prolong the service life of chimney the chimney wall.
Description of drawings:
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the different application of Fig. 1 structure.
Fig. 3 is a different structure schematic diagram of the present utility model.
The specific embodiment
See Fig. 1, inner wall of stack composite anti-corrosive structure comprises on the surface conditioning agent bottom 2 that combines with inner wall of stack 1, the bottom 2 with glass blocks 4 intermediate layers of clay 3 bondings and the fluorine-containing rubber mass surface layer 5 on the intermediate layer.
The utility model anticorrosion structure is according to the difference to some extent on making of different chimneys.As newly-built steel stack, do derusting by sandblasting earlier at inner wall of stack 1 and handle, surface roughness 70 μ m, then brushing heat-resistant anticorrosive surface conditioning agent 2 several, 100 μ m; , then blade coating 2mm elastic cement 3 is built lightweight boron-containing glass piece 4, the about 163kg/m of its proportion with clay 3 again
3, sew on fluorine-containing rubber mass 5 multiple tracks of face blade coating, the about 38mm of anticorrosion structure thickness at foam glass brick 4 and clay 3 afterwards.For the novel concrete chimney, earlier inwall 1 be coated with sealing inorganic agent 2 several, 150 μ m; Mend and put down, build 42mm lightweight boron-containing glass pieces 4 with siliceous elastic cement 3 again, be coated with fluorine-containing rubber mass 5 multiple tracks at last, 300 μ m; Anticorrosion structure thickness 45mm.
In order to increase the intensity of anticorrosion structure, in surface conditioning agent 2 bottoms, can add heat resistance fiber, as shown in Figure 2.
See Fig. 3, on the basis of embodiment 1 structure, can also between bottom and intermediate layer, increase one deck fiber cloth 6 to increase the intensity of structure.As making to old chimney, inwall 1 is cleaned remove dust earlier, repair smoothly, be coated with and seal inorganic agent 2, and paste 0.2mm cloth of reinforcement fibers 6, build lightweight boron-containing glass piece 4, thickness 51mm with clay 3 again, be coated with fluorine-containing rubber mass 5 multiple tracks of sealing at last, thickness 400 μ m, anticorrosion structure thickness 53mm.
