Description
Technical field
The utility model relates to the recycling of the waste heat of coking, metallurgical engineering technical field, particularly set by a kind of economizer
Coke dry quenching boiler.
Background technique
Coke dry quenching boiler is the core equipment that thermal energy conversion is realized in dry coke quenching technique, and coke dry quenching boiler main function is drop
The temperature of low dry quenching system inertia recyclegas simultaneously absorbs its heat, generates steam to for heat and generating power, with reach make it is lazy
The heat of property recyclegas is utilized effectively, and saves the purpose of the energy.
Under the action of circulating fan, inertia recyclegas cools down 1000 DEG C or so of red-hot coke in dry put out in slot,
The inertia recyclegas for absorbing coke sensible heat is heated to 880~960 DEG C, and high temperature inert recyclegas is removed through disposable dust remover
After dirt, into the steam-water heat exchanging in coke dry quenching boiler, with coke dry quenching boiler, temperature is down to 160~180 DEG C, inertia recyclegas
After secondary filter, circulating fan and heat exchange of heat pipe, temperature is down to 130 DEG C or so, enter back into it is dry put out slot cooling it is red
Hot coke.
Coke dry quenching boiler is connected with coke dry quenching furnace by the flue of fire resisting brick masonry, this makes the recyclegas of coke dry quenching boiler
Entrance absolute altitude must be consistent with the recyclegas spout elevation of coke dry quenching furnace.
In order to more recycle the heat of recyclegas to generate more steam, or in order to generate the steaming of higher quality
Vapour is increased the heat exchange area of final stage heating surface in coke dry quenching boiler with increasing system power benefit, or in coke dry quenching boiler
In add the modes such as reheater, will be so that boiler height increases, the absolute altitude that will cause coke dry quenching boiler recyclegas entrance is more than
The recyclegas spout elevation of coke dry quenching furnace.Common solution, first is that the basis of coke dry quenching furnace is improved, to improve coke dry quenching furnace
Recyclegas spout elevation；Second is that coke dry quenching boiler is digged pit arrangement, to reduce the recyclegas entrance mark of coke dry quenching boiler
It is high.
Above method will all be brought a negative impact: the blanking height of coke dry quenching furnace may be not enough；Cold coke belt may expose
Ground increases fugitive dust；Boiler low position is easy ponding, and steel structure frame is perishable, etc..
Summary of the invention
The purpose of the utility model is to provide a kind of structural good, circulating air for being adjustable coke dry quenching boiler of rational technology
The coke dry quenching boiler set by the economizer of body entrance absolute altitude.
The purpose of this utility model is to be achieved through the following technical solutions: the coke dry quenching boiler set by a kind of economizer,
It is characterized in: sets between shell in coke dry quenching boiler ontology shell and side using revolution flue connection, the interior arrangement of boiler body shell
There is heating surface of boiler proper group, and keep the absolute altitude of recyclegas entrance consistent with coke dry quenching furnace circulating air spout elevation, is set in shell on side
Arrangement is other to set economizer, and recyclegas outlet is connect with secondary filter.
The recyclegas import is made by fire resisting pouring material or refractory brick and steel construction.
The boiler body shell is the support construction being made into steel construction, and inside arrangement heating surface, heating surface presses grade
Arrangement.
It is the support construction that steel construction is made into that shell is set on the side, inside arrangement economizer surface.
The coke dry quenching boiler recyclegas outlet orientation is upward.
The revolution flue is the exhaust gases passes made by steel plate.
The recyclegas outlet is welded to form by steel plate.
The heating surface of boiler proper group includes membrane wall, superheater, reheater, evaporator, and heating surface is by snakelike light pipe
Or snakelike extended surface tube rearranges.
Set the heating surface that economizer is made of steel pipe or cast iron pipe in the side.
The effect of the utility model is: by setting boiler body side by economizer, effectively adjusting boiler body and following
Ring gas access absolute altitude puts out boiler body loop body entrance absolute altitude with dry in the case where increasing heating surface type or area
Furnace recyclegas spout elevation is consistent, to guarantee that integrated artistic layout does not change.
Detailed description of the invention
Below with reference to embodiment attached drawing, the invention will be further described:
Fig. 1 is the coke dry quenching boiler structural schematic diagram set by economizer of the embodiment of the present invention；
In figure: 1, recyclegas entrance, 2, boiler body shell, 3, side set shell, 4, revolution flue, 5, recyclegas goes out
Mouthful, 6, heating surface of boiler proper group, 7, side set economizer.
Specific embodiment
As shown in Figure 1, the coke dry quenching boiler set by a kind of economizer, sets shell 3 in coke dry quenching boiler ontology shell 2 and side
Between connected using revolution flue 4, be disposed with heating surface of boiler proper group 6 in boiler body shell, and make the mark of recyclegas entrance 1
It is high consistent with coke dry quenching furnace circulating air spout elevation, set on side and set economizer 7 in shell 3 by arrangement, recyclegas export 5 with it is secondary
Deduster connection.
Recyclegas import 1 is made by fire resisting pouring material or refractory brick and steel construction, is that dry coke quenching recyclegas enters pot
The channel of furnace.
Boiler body shell 2 is the support construction being made into steel construction, and heating surfaces at different levels are arranged in inside, can bear certain lotus
It carries.
It is the support construction that steel construction is made into that shell 3 is set on side, and inside arrangement economizer surface can bear a constant load.
Revolution flue 4 is the exhaust gases passes made by steel plate, and the recyclegas of boiler body is introduced side and sets shell 3 by it,
And cinerary device is according to circumstances set.
Recyclegas outlet 5 is welded to form by steel plate, the recyclegas discharge by it, after the completion of exchanging heat.
Heating surface of boiler proper group 6 is made of heating surfaces at different levels, it includes membrane wall, superheater, reheater, evaporator, by
Hot face is rearranged by snakelike light pipe or snakelike extended surface tube, and there are certain space for maintenances between each heating surface.
The heating surface that economizer 7 is made of steel pipe or cast iron pipe is set on side, is mounted on side and is set in shell, utilizes boiler flue
The heat of tail portion low-temperature circulating gas heats water supply, to reduce exhaust gas temperature, improves boiler thermal efficiency.
It illustrates, economizer 7 is set on side can be to be one or several, and side, which is set to side, can be one or several
It is a, no matter which kind of situation, belong to the content of this letter of authorization.
