Description
Technical field
The present invention relates to a kind of chimney, especially a kind of glass fiber reinforced plastic chimney.
Background technology
Chimney is to use the fume extractor in various boilers, and large-scale traditionally chimney adopts concrete or carbon steel smoke evacuation tube to make more, and cost is high, long construction period.During concrete the application, all need do preservative treatment to chimney, the practice commonly used is that its inwall is made frp lining, is in use discharged the flue gas repeated heating, is prone to cause coming off of lining, is difficult to safeguard.
In the dedusting field; Flue gas after wet dedusting or the wet desulphurization belongs to wet flue gas, about about 50 ℃ of temperature, and wet flue gas contains macro-corrosion property material (sulfuric acid that water droplet and sulfur dioxide form); Particularly be lower than under the situation of flue gas dew point at exhaust gas temperature; A smoke stack emission of adopting traditional cylindrical concrete or carbon steel smoke evacuation tube to make need be done preservative treatment to chimney, perhaps to flue gas heating behind the absorption tower to promote the fume emission height.For the discharging of wet flue gas, the glass fiber reinforced plastic chimney is to select preferably, and U.S.'s glass fiber reinforced plastic material chimney has accounted for 10-15%; Glass fiber reinforced plastic material chemical-resistance is good; Be particularly suitable for flue gas desulfurization humidity and sour environment, the later maintenance workload is little, and overall cost is superior to ordinary carbon steel and adds corrosion-proof lining; Long working life is the suitable material of the follow-up smoke evacuation of Industrial Boiler fume desulfurating absorption tower.
Though glass-reinforced plastic material has corrosion-resistant, plurality of advantages such as relative cost is low is when glass fiber reinforced plastic is applied to large-scale chimney; The problem that exists at present is that the rigidity of glass fiber reinforced plastic self is less, especially highly surpasses the chimney that the 60m diameter surpasses 1m; Directly as chimney barrel; Its cylindrical shell self can not play good self-supporting effect, so at present many inner cores as concrete or carbon steel chimney use, it is whole or be divided on the inwall that piece is fixed in concrete or carbon steel chimney to be about to corresponding glass fiber reinforced plastic inner core; Like the disclosed a kind of LARGE DIAMETER FRP inner core that is installed in the major diameter chimney of Chinese patent document CN201652392U; It is installed in the large diameter concrete chimney or the steelframe chimney in, vertically connect and compose by the LARGE DIAMETER FRP cylindrical shell unit of plurality of sections, said cylindrical shell comprises the some cylindrical shell arc sheets that along the circumferential direction connect successively; The one end overlap joint of each said cylindrical shell arc sheet is in the inboard of the adjacent cylindrical shell arc of this end sheet, and its other end overlap joint is in the outside of the adjacent cylindrical shell arc of this other end sheet.But the problem of thereupon bringing is; Both coefficient of thermal expansion differ bigger; Corresponding expansion joint need be installed between the glass fiber reinforced plastic cylindrical shell of certain-length; CN101619855A discloses a kind of chimney internal cylinder glass fiber reinforced plastic expansion joint like the Chinese patent document, or is exactly the expansion joint that adopts stainless steel material, otherwise will cause the broken ring of self structure because of the existence of thermal expansion.
The problem and the corresponding solution that more than exist, though make glass-reinforced plastic material build the application that the peace field has obtained certain limit at chimney, because of it still exists the on-the-spot inconvenient installation of making; The high shortcoming of the whole cost of chimney; And most transformations of being based on existing chimney still can not provide a kind of real glass fiber reinforced plastic chimney, have adult low, be easy to make the characteristics of installation; The concrete or the steel stack that replace design at present to use on the whole make things convenient for promoting the use of of market.
Summary of the invention
The object of the present invention is to provide a kind of brand-new glass fiber reinforced plastic chimney, the transformation that it can be used for existing large-sized concrete or steel stack also can replace existing large-sized concrete or steel stack fully.
The objective of the invention is to realize through following technical scheme:
A kind of glass fiber reinforced plastic chimney comprises the glass fiber reinforced plastic cylindrical shell, and said glass fiber reinforced plastic cylindrical shell is installed on the inwall or steel tower of intrinsic chimney through the elastomeric element suspension.
Preferably, said elastomeric element is a spring; Said spring is provided with when mounted and gives tight power accordingly, and has the different elasticity coefficient at various height.
Further, said glass fiber reinforced plastic cylindrical shell is connected in turn by a plurality of shell rings, adopts flange to connect between the adjacent cylindrical section; Said shell ring end is tapered, and said flange is the loose flange that cooperates with it; The stiffening ring that is provided with separated by a distance on the shell ring.
Said intrinsic chimney is concrete chimney or steel stack.
The cross section structure form of said steel tower is triangle, quadrangle or polygon.
Said glass fiber reinforced plastic cylindrical shell is the multitube combining structure.
Said steel tower is provided with drag-line to carry out mooring and fixes.
Glass fiber reinforced plastic chimney of the present invention; Employing is installed on the inwall of intrinsic chimney or the structure on the steel tower with whole glass fiber reinforced plastic cylindrical shell through the elastomeric element suspension; Utilize the elastic force of elastomeric element, the difference between the thermal expansion stroke of glass fiber reinforced plastic cylindrical shell and the thermal expansion stroke of load-carrying members is absorbed by the elastic telescopic of spring, can effectively solve glass fiber reinforced plastic cylindrical shell and an outside intrinsic chimney wall or the different difficult problems of bringing of steel tower coefficient of thermal expansion; Cooperate steel tower; A kind of glass fiber reinforced plastic chimney that can replace existing concrete or steel stack is provided, has had lower construction cost and good performance, had higher industrial application value.
