Abstract
The utility model discloses an anticorrosive double-layer chimney, which comprises a chimney body. A chimney wall is of a double steel plate structure, and a heat-insulation material layer is arranged between the double steel plates; the steel plate at the inner side of the chimney wall is a weathering steel layer; and the inner steel plate and the outer steel plate are in non-rigid connection. The design of the utility model can protect the whole chimney, strengthen the rigidity of the chimney and greatly avoid the corrosion of flue gas.
Description
Technical field
The utility model relates to the double-deck chimney of a kind of anticorrosion.
Background technology
General chimney is concrete, brick, steel chimney at present.The steel chimney is easy for installation, short construction period.But the steel chimney mostly is single layer structure, because corrosive deposits such as remaining HCL of tail gas and SO2 are subjected to its comprehensive function, there is the not enough defective of decay resistance in common iron, and the flue gas contact surface need carry out corrosion-inhibiting coating to be handled.But the chimney wall still often occurs by the flue gas corrosion attenuation, even local open-work occurs, the serious chimney that causes fractures, and has had a strong impact on the application life of chimney, and has bigger potential safety hazard.
Summary of the invention
The purpose of this utility model provides the double-deck chimney of a kind of anticorrosion, not only can accomplish Global Macros but also do not lose it and strengthen rigidity.
For achieving the above object, the utility model is taked following design scheme:
The double-deck chimney of a kind of anticorrosion comprises chimney body, and described chimney wall is a double steel plate layer structure, fill insulant material layer between double-layer plate.
The inboard steel plate layer of described chimney wall is the weathering steel layer.
Take non-rigid connection in the middle of the described inside and outside double-layer plate.
Above-mentioned weathering steel (weathering steel; Be weather resisting steel) be the low-alloy steel series between ordinary steel and stainless steel, belong to one of steel series of World super steel frontline technology level, this steel grade has antirust, makes that member is anticorrosively lengthened the life, the attenuate consumption reduction, the characteristic that the saving of labor is energy-conservation.
The utility model has the advantages that:
1, two steel work make the double-deck chimney of the utility model anticorrosion can have higher intensity, and easy for installation, short construction period.
2, because the corrosion resistance of inboard weathering steel has inserted and put the heat insulating material that can keep flue-gas temperature to be higher than dew point in the middle of reaching, so can significantly overcome flue gas corrosion.
Description of drawings
Fig. 1 is the double-deck chimney structure schematic diagram of the utility model anticorrosion
Below in conjunction with drawings and the specific embodiments the utility model is described further:
The specific embodiment
Consult shown in Figure 1ly, the double-deck chimney of the utility model anticorrosion is the chimney body 1 of conventional form.
Described chimney wall is inside and outside double steel plate layer structure, and 101,102 of double-layer plates have adiabator layer 103.
The steel plate layer 101 of described chimney wall inboard should select for use weather-resistant steel plate to make, and it has corrosion resistance preferably.
The adiabator layer of described centre can adopt materials such as mineral wool or alumina silicate fiber felt, fills in whole plate mode, is higher than dew point can guarantee flue-gas temperature, prevents flue gas in the inwall generation acid solution that uncovers, thereby has improved the resistance to corrosion of chimney.
For preventing the internal-external temperature difference effect, produce dilatancy, take non-rigid 104 to connect in the middle of the double-layer plate, both guaranteed the even distribution of packing material, guaranteed the chimney integral rigidity again.
