Abstract
The utility model belongs to structures, and relates to a rectangular multi-tube sleeve type smokestack for a waste incineration power station. The rectangular multi-tube sleeve type smokestack comprises a concrete outer sleeve, more than one steel smoke exhaust inner sleeves, a steel platform, more than one smoke passages and a concrete platform, wherein the concrete outer sleeve is rectangular, the steel smoke exhaust inner sleeves are arranged vertically and parallelly inside the rectangular concrete outer sleeve; the smoke passages penetrate through the lower part of the rectangular concrete outer sleeve respectively and horizontally and are connected to smoke passage inlets formed in the steel smoke exhaust inner sleeves; and the vertically and parallelly arranged steel smoke exhaust inner sleeves are horizontally supported and fixed by adopting the steel platform. The smokestack realizes independent gas exhaust of a single furnace, achieves a longer service life, diversifies the shape of the outer sleeve, reduces the construction difficulty, shortens the construction period, and saves a template.
Description
Technical field
The utility model relates to a kind of telescopic chimney of rectangle multitube that is used for garbage incinerating power plant, belongs to the structure class.
Background technology
In recent years, along with the continuous growth of municipal refuse output, the garbage incinerating power plant quantity of domestic construction was also constantly increasing.For most city garbage burnings power plant, chimney all be absolutely necessary critical facility with have significant structure.
The waste incineration amount of garbage incinerating power plant is huge; A general incinerator is difficult to satisfy its burning demand; Need to be equipped with many flue gas incinerators, for traditional free-standing monotubular chimney, the flue gas of many incinerators can only be discharged from a chimney exhaust funnel; Yet the operation conditions of many incinerators is all different; If one or more incinerator shutdown maintenance wherein, flue gas exhaust discharge value and mass rate of emission will change so, thereby make flow velocity, flow and the temperature of flue gas in the chimney exhaust funnel all be difficult to be controlled within the scope of design permission.In addition; Often contain strong corrosive materials such as chloride, fluoride and sulphite in the smoke components; Under the bigger situation of smoke moisture, acid solution may penetrate in the concrete of concrete stack shell through the not full masonry mortar joint in village in the chimney; Cause the concrete stack shell by heavy corrosion, influence the application life of chimney.
Consider the insoluble problems of monotubular chimney, present most of power plant generally adopt the telescopic chimney of multitube of circular concrete urceolus or subcircular concrete urceolus, but this stressed comparatively reasonable structure form; Structure and shape is more single; Construction is comparatively complicated, and floor space is bigger, considers that construction land is nervous; Many factors such as construction costs and maintenance cost impel us to have to the chimney structure system is constantly innovated and improved.
Summary of the invention
To above-mentioned existing problems, the purpose of the utility model is to provide a kind of telescopic chimney of rectangle multitube that is applied to garbage incinerating power plant, and for realizing above-mentioned purpose, the technical solution of the utility model is:
A kind of telescopic chimney of rectangle multitube that is used for garbage incinerating power plant; Comprise concrete urceolus, steel smoke evacuation inner core, flue; Concrete platform; The rectangular shape of described concrete urceolus, more than one steel smoke evacuation inner core vertical parallel is arranged and is arranged on Rectangular Concrete urceolus inside, and more than one flue is the bottom of level perforation Rectangular Concrete urceolus respectively; Be connected on the flue entrance that is located at steel smoke evacuation inner core, the steel smoke evacuation inner core that said vertical parallel is arranged adopts steel platform horizontal support to fix each other.
Described concrete platform is positioned at Rectangular Concrete urceolus top layer.
Described steel platform is more than one.
Owing to adopted above scheme, the utlity model has following advantage:
1, realized the independent exhaust of single stove; A plurality of incinerator discharged flue gas are not disturbed each other, have effectively controlled flow velocity, flow and the temperature of discharging flue gas, have guaranteed the stability of each index of discharging flue gas; Also avoid the primary structure member of flue gas corrosion chimney, prolonged the application life of chimney.
2, break through the chimney urceolus moulding of present routine, realized the variation of chimney urceolus moulding.
3, for tall and slender structure, rectangular configuration can reduce difficulty of construction, the reduction of erection time, practices thrift template.
4, Rectangular Concrete urceolus shear wall structure is calculated and is adopted finite element method, under the prerequisite that satisfies existing related specifications of China and standard, can guarantee the safety and the reliability of concrete urceolus and steel smoke evacuation inner core.
5, the inner steel platform of Rectangular Concrete urceolus can doublely be done the horizontal support system of steel smoke evacuation inner core, and the layout of steel platform is optimized more, can reduce the steel use amount, practices thrift construction costs.
6, Rectangular Concrete urceolus top concrete platform can also play the effect that strengthens concrete urceolus integral rigidity as the external maintenance structure of chimney.
Description of drawings
Accompanying drawing 1 is the structural representation of the telescopic chimney structure of the utility model rectangle multitube.
Accompanying drawing 2 is the A-A generalized section of accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Consult shown in the accompanying drawing, a kind of telescopic chimney of rectangle multitube that is used for garbage incinerating power plant, it is made up of concrete urceolus 1, steel smoke evacuation inner core 2, steel platform 3, flue entrance 4, flue 5, concrete platform 6.Concrete urceolus 1 rectangular shape is a primary structure member of mainly bearing the external loads effect, and stack shell also can be provided with turnover gate and vent window; Steel smoke evacuation inner core 2 is more than one, is provided with according to the incinerator number is corresponding, and steel smoke evacuation inner core 2 vertical parallel are arranged and are arranged on Rectangular Concrete urceolus 1 inside; Load-bearing concrete urceolus 1 was opened with steel smoke evacuation inner core in 2 minutes, made the urceolus primary structure member not contact with corrosive fume, reached the best user mode of chimney structure; Prolong the application life of chimney, steel smoke evacuation inner core 2 is designed to the self-supporting steel cylinder, is the self-supporting member; Do not bear external loads, steel smoke evacuation inner core 2 adopts steel platform 3 horizontal supports to fix each other, and steel platform 3 opposite sides are fixed on the inwall of concrete urceolus 1; According to design demand, steel platform 3 is more than one, also can adopt the composite floor structure; Realization is conducted oneself with dignity through the increase chimney and is improved the whole resistance to capsizing of chimney, thereby increases the rigidity of concrete urceolus 1, and flue 5 is the bottom of levels perforation Rectangular Concrete urceolus 1 respectively; Be connected on the flue entrance 4 that is located at steel smoke evacuation inner core 2, flue 5 is according to the corresponding setting of number and plan-position of incinerator, and concrete platform 6 is positioned at the top layer of Rectangular Concrete urceolus 1; As the top space enclosing structure of chimney waterproof and dustproof effect, can increase the integral rigidity of concrete urceolus 1, on the concrete platform 6 manhole can be set.
The utility model is not limited to garbage incinerating power plant, is applicable to that too other need be provided with the chimney structure of fume emission device, and this structure is to be radix with two pipe box tubes, and sleeve quantity can be arranged with the quantity of technology incinerator again.
