Abstract
The utility model discloses a clean flue device for flue gas desulfurization works, which comprises a flue made of an FPR (fiber reinforced plastics) material; a smoke inlet of the flue is communicated with a smoke vent of a desulfurization tower; in the clean flue device for the flue gas desulfurization works, the flue made of the FPR material is highly anti-corrosive; no anti-corrosive material is required to be stuck in the flue; the flue has low cost and light weight; a span can reach 40m in the erecting works of the flue; therefore, many support devices and much civil engineering investment can be reduced.
Description
Technical field
The utility model relates to a kind of flue, the flue gas desulphurization flue that particularly a kind of corrosion resistance is strong.
Background technology
At present, the clean flue behind the known fume desulfurating absorption tower adopts carbon steel material, be corroded in order to prevent steel flue gas duct, inner anticorrosion process all be according to national regulation with scale or serve as a contrast nickelic plate and carry out preservative treatment.But in the prior art, according to panel method or serve as a contrast nickelic plate method to carry out preservative treatment all be to adopt the homogeneous antisepsis, inside, absorption tower antiseptic power everywhere all is identical.But, since the difference of the corrosion-resistant degree of the inner zones of different in absorption tower, the zonal corrosion degree height that has, the zonal corrosion degree that has is low, therefore, adopts the homogeneous corrosion protection design, all sites all must advance according to the easiest requirement for anticorrosion that is corroded the zone, and resource and cost are caused huge waste.And steel matter flue quality is big, and from great, so the flue span is little, and the backing material of employing is also more.So the clean flue cost of present known flue gas is higher.
Therefore need improve clean cigarette flue of the prior art, when making it have the good corrosion resistance advantage, have also that quality is little, span is big, support member is few, characteristics such as low cost of manufacture.
Summary of the invention
In view of this, the purpose of this utility model provides the clean flue device of a kind of flue-gas desulfurizing engineering, and characteristics such as it has good corrosion resistance, light weight, span is big, support member is few, low cost of manufacture have good practice and are worth.
The clean flue device of the utility model flue-gas desulfurizing engineering comprises the flue of being made by the FRP material, and described flue advances mouth and is communicated with the exhaust opening of desulfurizing tower.
Further, the span of described flue is 30～40m;
Further, described flue below is provided with support column, and described support column is one.
The beneficial effects of the utility model: the clean flue device of the utility model flue-gas desulfurizing engineering, the flue of being made by the FRP material has excellent corrosion resisting performance, need not in flue, to paste anti-corrosion material, the flue low cost, and flue light weight, set up the span that can reach 40m in the engineering at flue, thereby can reduce a large amount of bracing or strutting arrangements and civil engineering input.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is the clean flue device structural representation of the utility model flue-gas desulfurizing engineering.
The specific embodiment
Accompanying drawing is the clean flue device structural representation of the utility model flue-gas desulfurizing engineering.
As shown in the figure, the clean flue device of the utility model flue-gas desulfurizing engineering comprises the flue of being made by the FRP material 1, and described flue 1 advances mouth and is communicated with the exhaust opening of desulfurizing tower 2.The flue of being made by the FRP material itself has excellent corrosion resisting performance, need not to paste in flue anti-corrosion material, flue low cost, and flue light weight, and it is big to set up in the engineering span at flue, thereby can reduce a large amount of bracing or strutting arrangements and civil engineering input.
In the present embodiment: the span of described flue 1 is 40m, and the flue span is comparatively reasonable between 30～40m in concrete enforcement certainly, both can save a large amount of bracing or strutting arrangements and civil engineering input, can guarantee that again flue has enough intensity and steadiness.
In the present embodiment: described flue 1 below is provided with support column 3, and described support column 3 is one, support column is set can makes flue structure more firm, and reliability is higher, and support column quantity is few, the civil engineering less investment.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
