Abstract
The utility model discloses a corrosion-resistant layer structure of a steel girder in a spray area of a desulfurization absorption tower, which comprises a supporting girder steel basal body arranged at the innermost layer, a resin flake layer is arranged outside the supporting girder steel base body, a glass steel layer is arranged outside the resin flake layer, and a polypropylene layer is arranged outside the glass steel layer. The vinyl ester resin flake layer with 9-millimeter thick, the glass steel layer and the polypropylene layer are used as the corrosion-resistant layer structure of the steel girder in the spray area, therefore, the corrosion-resistant layer structure can prevent corrosion of acid liquor and scouring of smoke, has been practically used for more than 2 years without the phenomenon of corrosion and leakage caused by problems of self structure of the corrosion-resistant layer, avoids leakage of acid liquor caused by damage of the corrosion-resistant layer for power plants, and further avoids environment pollution.
Description
Technical field
The utility model relates to a kind of anti-corrosion layer structure, the anti-corrosion layer structure of particularly a kind of desulfuration absorbing tower spray district girder steel.
Background technology
A large amount of SO2 are contained from the flue gas of boiler emission in thermal power plant before not setting up desulfurizer, directly the chimney by power plant enters atmosphere, and SO2 combines the formation acid solution with airborne moisture, accumulate over a long period with the form contaminated environment of acid rain, influences the healthy of people.After the power plant desulfurization device was set up, this environmental issue was just solved.The nucleus equipment of desulfurizer is a desulfuration absorbing tower, and it is the cardiac component of desulfurizer, and desulfuration absorbing tower adds that by carbon steel structure rational anti-corrosion layer structure forms, and therefore selects rational anti-corrosion layer structure very important.Because containing the flue gas of a large amount of SO2 passes through from desulfuration absorbing tower; so whole desulfurizing tower inside is sour environment; the corrosion protective covering structure of carrying out desulfurizing tower inside is very important; if it is unreasonable that anti-corrosion layer structure is selected, corrosion protective covering does not play the protection buffer action, and acid solution is passed anti-corrosion layer structure and is penetrated into carbon steel shell; corrosion carbon steel shell and boring a hole; a large amount of acid liquor leakages go out the desulfurizing tower contaminated environment, even cause desulfurizing tower not use, and entire power plant is shut down the serious consequence that can not generate electricity.
In the prior art, a kind of scheme is to utilize the C276 alloy sheets to wrap up girder steel as anticorrosive coat, and its effect is better, but there is the too high weak point of cost in it;
In the prior art, also having a kind of scheme is to utilize rubber slab to do anticorrosive coat parcel girder steel, its antiseptic effect is better, but still have the higher defective of cost, and simultaneously, its wear-resisting poor effect, generally, operation 2-3, the phenomenon that rubber slab is washed away, bores a hole happens occasionally, the corresponding high problem of maintenance cost of bringing.
In the prior art, also having a kind of scheme is to adopt the vinyl ester resin scale to add fiberglass parcel girder steel, favorable anti-corrosion effect, but still there is a higher defective of cost, simultaneously, its wear-resisting weak effect used about 1 year, the phenomenon that anticorrosive coat is washed away perforation is many, the corresponding high problem of maintenance cost of bringing.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of and can prevent anticorrosive coat acid liquid corrosion and sweep of gases, with low cost.
The technical solution adopted in the utility model is such: the anti-corrosion layer structure of a kind of desulfuration absorbing tower spray district girder steel, comprise the brace summer steel matrix that is arranged at innermost layer, described brace summer steel matrix is outside equipped with the resin scale layer, described resin scale layer is outside equipped with frp layer, and described frp layer is outside equipped with polypropylene layer.
Described resin scale layer is the vinyl ester resin scale layer.
Described polypropylene layer thickness is 5mm.
Described frp layer thickness is 2mm.
Described resin scale layer thickness is 2mm.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, the vinyl ester resin scale glass steel that adopts in the utility model adds polypropylene board as spraying district's girder steel anti-corrosion layer structure and comparing as anticorrosive coat with C276, and is corrosion-resistant suitable with wearability, but expense is lower;
2, the vinyl ester resin scale glass steel that adopts in the utility model adds polypropylene board as spraying district's girder steel anti-corrosion layer structure and comparing as anticorrosive coat with rubber layer, and corrosion resistance is suitable, and wearability is better, and expense is lower.
3, than the other technologies scheme, the vinyl ester resin scale glass steel of gross thickness 9 ㎜ adds that polypropylene layer is as spray district girder steel anti-corrosion layer structure, can prevent acid liquid corrosion and sweep of gases, reached more than 2 years through the practice time, no any phenomenon because of anticorrosive coat self structure problem generation corrosion leakage, avoided power plant to damage, acid liquor leakage has taken place, caused environmental pollution problems because of anticorrosive coat.
