Abstract
The utility model relates to a corrosion-proof desulfurization chimney which is provided with a steel inner tube. A corrosion-proof coating is arranged on the inner surface of the steel inner tube and sequentially comprises a resin layer, a glass fiber structure layer and an abrasion-resistant face layer from inside to outside. The thickness of the resin layer is 0.2-0.5mm, the thickness of the glass fiber structure layer is 3.5-4.5mm, and the thickness of the abrasion-resistant face layer is 0.5-1mm. The thickness of positions of the glass fiber structure layer at the bottom and below 600mm on two sides of the steel inner tube is 4.5mm, and the thickness of the glass fiber structure layer at other positions of the steel inner tube is 3.5mm. The corrosion-proof coating coated in the steel inner tube improves compactness and corrosion resistance, and is good in corrosion resistance and capable of withstanding strong corrosion environment of the chimney. Simultaneously, the chimney reduces pollution to environment.
Description
Technical field
The utility model relates to a kind of anticorrosion desulfuration chimney.
Background technology
Along with the in-depth that Environmental Protection in China is administered, the chimney etching problem after the wet desulphurization is more and more outstanding, particularly after the denitration, a large amount of SO2 change into SO3, wet flue gas is even more serious to the corrosion of chimney, even the safe operation of power plant has been caused huge threat, has arrived the stage of improvement.Although the seriousness of problem has also been seen by many anticorrosion companies, but in the design feature that does not have fully to understand characteristic, corrosion mechanism and the chimney of wet flue gas, and do not possess in the situation of design research and development ability, various inappropriate anti-corrosion materials have been used, facts have proved substantially unsuccessfully, force the part owner to have to select rare metal titanium plate or full import Bin Gaode product.This bi-material not only price height but also long construction period, construction requirement is high, titanium plate particularly is the strategic materials of state control at planned economy era titanium then, " killing chicken unexpectedly with the cutter of slaughtering an ox ", serious mass excess is so that owner's contradiction very on anticorrosion Scheme Choice.
Long-time running along with desulfurizer, the chimney etching problem becomes increasingly conspicuous, even had influence on the structural safety of chimney, cause the common concern of genco, particularly in recent years, through the corrosion-resistant chimney, the anticorrosion failure phenomenons such as anticorrosive coat ftractures, comes off, corrosion appearred much, cause flue gas condensing liquid seepage, seriously jeopardize chimney safety.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of anticorrosion desulfuration chimney is provided, the antiseptic property of chimney is better.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of anticorrosion desulfuration chimney, has steel inner cylinder, described steel inner cylinder inner surface scribbles corrosion-inhibiting coating, described corrosion-inhibiting coating comprises resin bed, glass fibre structure layer, wear-resistant coat from the inside to surface successively, the thickness of described resin bed is 0.2～0.5mm, the thickness of described glass fibre structure layer is 3.5～4.5mm, and the thickness of described wear-resistant coat is 0.5～1mm.
Further, the thickness of the glass fibre structure layer at described steel inner cylinder bottom and the following position of 600mm, both sides is 4.5mm, and the thickness of the glass fibre structure layer at other positions of described steel inner cylinder is 3.5mm.
Further, the thickness of described wear-resistant coat is 0.5mm.
Further, the thickness of described wear-resistant coat is 1mm.
The beneficial effects of the utility model are: after scribbling corrosion-inhibiting coating in the steel inner cylinder of the present utility model, this corrosion-inhibiting coating has promoted compactness and antiseptic property, antiseptic effect is better, can tolerate the strong corrosive environment of chimney, owing to do not add banana oil, acetone equal solvent, can because the volatilization of solvent and use cause injury to the workmen, simultaneously, not reduce the pollution to environment yet.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. steel inner cylinder, 2. resin bed, 3. glass fibre structure layer, 4. wear-resistant coat.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of anticorrosion desulfuration chimney, has steel inner cylinder 1, steel inner cylinder 1 inner surface scribbles corrosion-inhibiting coating, corrosion-inhibiting coating comprises resin bed 2, glass fibre structure layer 3, wear-resistant coat 4 from the inside to surface successively, the thickness of resin bed 2 is 0.2～0.5mm, and the thickness of glass fibre structure layer 3 is 3.5～4.5mm, and the thickness of wear-resistant coat 4 is 0.5～1mm.The thickness of wear-resistant coat 4 is preferably 0.5mm.
The thickness of the glass fibre structure layer 3 at steel inner cylinder 1 bottom and the following position of 600mm, both sides is preferably 4.5mm, and the thickness of the glass fibre structure layer 3 at steel inner cylinder 1 other positions is preferably 3.5mm.
After scribbling corrosion-inhibiting coating in the steel inner cylinder 1 of the present utility model, this corrosion-inhibiting coating has promoted compactness and antiseptic property, antiseptic effect is better, can tolerate the strong corrosive environment of chimney, owing to do not add banana oil, acetone equal solvent, can because the volatilization of solvent and use cause injury to the workmen, simultaneously, not reduce the pollution to environment yet.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
