Description
Technical field
The utility model relates to a kind of dual firing chamber.
Background technology
Dangerous waste incineration line is provided with dual firing chamber, for smoke secondary Thorough combustion, reduces the generation of harmful substance; Dual firing chamber designs normally monoblock type dual firing chamber, and after equipment cold conditions installs, burner is run, and the supporting steel plate outer wall of dual firing chamber is usually at 200 DEG C, and the temperature of the steelframe of fixing dual firing chamber is environment temperature; Owing to expanding with heat and contract with cold, dual firing chamber's overall thermal expands comparatively large, and fixing steelframe can produce very large distortion, and steel frame deformation is also inconsistent up and down, produce damaging active force between equipment and steelframe, the equipment that affects normally runs, and can cause the damage of equipment time serious.
For the problem in correlation technique, at present effective solution is not yet proposed.
Utility model content
The purpose of this utility model is to provide a kind of dual firing chamber, to overcome currently available technology above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of dual firing chamber, comprise dual firing chamber's body, described dual firing chamber body is made up of load-bearing steel plate, the top of described dual firing chamber body and bottom are respectively equipped with the upper support steelframe and bottom support steelframe that match, between described upper support steelframe and bottom support steelframe and the medium position place being positioned at described dual firing chamber body is provided with expansion joint two, and the side on described dual firing chamber's body top is provided with exhanst gas outlet, and described smoke outlet is provided with expansion joint one.
Preferably, the material of described load-bearing steel plate is carbon structural steels Q235B.
Further, described expansion joint one is identical with the structure of expansion joint two.
The beneficial effects of the utility model are: the dual firing chamber in the application is segmentation supporting construction, and the load-bearing of upper and lower dual firing chamber is on upper and lower supporting steel frame; And be provided with the expansion joint of retractility, the two-part thermal expansion of top dual firing chamber and bottom dual firing chamber and the thermal expansion with boiler can be eliminated, avoid the destruction that thermal stress causes; Dual firing chamber's top free wxpansion, fix without steelframe, effectively solve because upper and lower steel frame deformation is also inconsistent, and cause between equipment and steelframe, producing damaging active force, the problem that the equipment that affects normally runs, the stability that the equipment that improves normally runs and reliability.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of dual firing chamber according to the utility model embodiment;
Fig. 2 is expansion joint one and expansion joint two structural representation of a kind of dual firing chamber according to the utility model embodiment.
In figure:
1, dual firing chamber's body; 2, dual firing chamber top; 3, exhanst gas outlet; 4, expansion joint one; 5, upper support steelframe; 6, load-bearing steel plate; 7, expansion joint two; 8, bottom support steelframe.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As shown in Figure 1-2, according to a kind of dual firing chamber of the utility model embodiment, comprise dual firing chamber's body 1, described dual firing chamber body 1 is made up of load-bearing steel plate 6, the top of described dual firing chamber body 1 and bottom are respectively equipped with the upper support steelframe 5 and bottom support steelframe 8 that match, between described upper support steelframe 5 and bottom support steelframe 8 and the medium position place being positioned at described dual firing chamber body 1 is provided with expansion joint 27, and the side on described dual firing chamber body 1 top is provided with exhanst gas outlet 3, described exhanst gas outlet 3 place is provided with expansion joint 1.
The material of described load-bearing steel plate 6 is carbon structural steels Q235B, concrete effect due to described load-bearing steel plate 6 is the bulk material forming dual firing chamber's equipment, realize the material foundation of dual firing chamber's function, the weight of load-bearing self and refractory material, insulation material, and adopt carbon structural steels Q235B to form load-bearing steel plate 6, there is hardness higher, and not easily suffer damage, effectively ensure that the toughness of device, improve the service time of device.
Described expansion joint 1 is identical with the structure of expansion joint 27.
During concrete use, dual firing chamber carries out segment design, and be divided into top dual firing chamber and bottom dual firing chamber two parts, centre arranges telescopic expansion joint 27, top dual firing chamber and bottom dual firing chamber two parts are flexibly linked into an integrated entity, the first half dual firing chamber weight is supported by described upper support steelframe 5; The latter half dual firing chamber weight is supported by described bottom support steelframe 8; Like this, the distortion caused due to dual firing chamber's thermal expansion just can be born by upper support steelframe 5 and bottom support steelframe 8 respectively, and expansion joint 27 makes flexible being compensated of dual firing chamber and eliminates the impact of thermal stress; Described dual firing chamber top 2 is fixed without steelframe, therefore can free wxpansion, and the exhanst gas outlet 3 of dual firing chamber is provided with expansion joint 1, and described expansion joint 1 is connected with boiler, and thermal expansion can be avoided to produce distortion.
In sum, by means of technique scheme of the present utility model, be segmentation supporting construction by the dual firing chamber in the application, the load-bearing of upper and lower dual firing chamber is on upper support steelframe 5 and bottom support steelframe 8; Expansion joint 1 and expansion joint 27 all have retractility, can eliminate the two-part thermal expansion of top dual firing chamber and bottom dual firing chamber and the thermal expansion with boiler, avoid the destruction that thermal stress causes; And top 2 free wxpansion of described dual firing chamber, fix without steelframe, effectively solve because upper and lower steel frame deformation is also inconsistent, and cause between equipment and steelframe, producing damaging active force, the problem that the equipment that affects normally runs, the stability that the equipment that improves normally runs and reliability.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
