Abstract
The invention relates to the technical field of chimney equipment, in particular to a stainless steel lined chimney for a thermal power plant. The stainless steel lined chimney comprises a reinforced concrete shell and a stainless steel plate which is arranged in the reinforced concrete shell, wherein a bracket is arranged between the stainless steel plate and the reinforced concrete shell and is used for connecting and supporting the stainless steel plate and the reinforced concrete shell. By using the structure, a refractory brick chimney lining is substituted by the stainless steel plate; since the surface of the stainless steel plate is smooth and corrosion-resistant and has small smoke exhaust resistance, the height of the chimney can be reduced, the diameter can also be reduced, the dead weight of the chimney is greatly reduced, a foundation pit is not required to be dug too deep, and the manufacturing cost is greatly reduced.
Description
Technical field
The present invention relates to the chimney arrangement technical field, be specifically related to thermal power generation station-service inner liner stainless steel chimney.
Background technology
Traditional Chimney in Fossil Power Plant, be all the steel concrete shell, and inside builds refractory brick by laying bricks or stones and insulating brick is done liner.Along with the continuous increase of generating set capacity, chimney is more and more higher, and diameter is also more and more thicker.The floor space of chimney raft is also increasing thereupon, and foundation pit also digs darker and darker, and cost is also more and more higher.
Summary of the invention
The thermal power generation station-service inner liner stainless steel chimney that the purpose of this invention is to provide that a kind of smooth surface is smooth, corrosion-resistant, little, the chimney height reduction of smoke evacuation resistance, reduced, cost reduces significantly.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: thermal power generation station-service inner liner stainless steel chimney, comprise steel concrete shell and the corrosion resistant plate of being located at described steel concrete enclosure, be provided with support between described corrosion resistant plate and steel concrete shell, described support connects and supports described corrosion resistant plate and steel concrete shell.
Further, described corrosion resistant plate is austenite stainless steel plate.
The present invention has following beneficial effect: thermal power generation station-service inner liner stainless steel chimney of the present invention, comprise steel concrete shell and the corrosion resistant plate of being located at the steel concrete enclosure, wherein, support connects and supports corrosion resistant plate and steel concrete shell; The present invention adopts said structure, substitute refractory brick volt chimney lining by corrosion resistant plate, because the corrosion resistant plate smooth surface is smooth, corrosion-resistant, the smoke evacuation resistance is little, thereby not only the height of chimney can reduce, diameter also can dwindle, the deadweight of chimney significantly reduces, and foundation ditch also needn't dig so dark, and cost is significantly reduced.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, thermal power generation station-service inner liner stainless steel chimney, comprise steel concrete shell 1 and the corrosion resistant plate 2 of being located at described steel concrete shell 1 inside, be provided with support 3 between described corrosion resistant plate 2 and steel concrete shell 1, described support 3 connects and supports described corrosion resistant plate 2 and steel concrete shell 1; Wherein, described corrosion resistant plate 2 is austenite stainless steel plate, in the present embodiment, can adopt SUS31GL or SUS304 corrosion resistant plate to substitute traditional refractory brick, because SUS31GL and SUS304 are austenitic stainless steels, thereby have intercrystalline corrosion under good corrosion resistance and high temperature resistance state, and good mechanical performance, its tensile strength are arranged is 520MPa/cm
2, yield strength 205 MPa/cm
2, application life is far away higher than fireproof brick inner lining, and do not need to safeguard in life cycle.
Explanation is finally, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of claim scope of the present invention.
Claims (2)
