Description
Technical field
The utility model relates to shaft furnaces, particularly relate to a kind of charcoal base directly reducing iron heat accumulating type shaft furnace.
Background technique
Direct reduced iron is the low-carbon cellular substance that smart iron powder or iron oxide are formed in furnace through low-temperature reduction, main to use
Make the raw material of electric furnace steel making.In electric furnace steel making, if a certain proportion of direct reduced iron is added, the uniform of steel can be increased
Property, the physical property of steel is improved, energy consumption and pollution are reduced.
The reducing agent of direct reduced iron has gas base and charcoal base at present, and gas base needs good also Primordial Qi, do not have in China
Price advantage, and the rich coal resources in China, the application are intended to using China's coal resources abundant, to direct reduced iron into
Row production.The combustion technology low efficiency of charcoal base directly reducing iron at present, not only can also cause environmental pollution, and can also consume and waste
Mass energy.Therefore, in order to improve energy conservation and the environmental benefit of charcoal base directly reducing iron reduction furnace, it would be highly desirable to change to its structure
Into optimization.
Utility model content
The utility model proposes a kind of charcoal base directly reducing iron heat accumulating type shaft furnaces, solve existing charcoal base directly reducing iron also
The problem that former furnace pollution is big, energy consumption is high.
The technical solution of the utility model is achieved in that a kind of charcoal base directly reducing iron heat accumulating type shaft furnace, including furnace
Body, the furnace body is interior to be equipped with combustion chamber and reduction room, and successively spacing parallel arranging is arranged with room is restored for combustion chamber, restores room and top
Feeding warehouse connection, reduction room be connected to the discharging bin of bottom, feeding warehouse is connected to the gas outlet on furnace body, gas outlet with purify
Device connection, the two ends of combustion chamber are equipped with accumulation of heat mouth and gas port on furnace body, and gas port is connected to purification device,
Reinforcement structure is equipped in combustion chamber, reinforcement structure interlaced arrangement is equipped with cooling water jecket at discharging bin.
The combustion chamber is divided into several layers by temperature partition, and commutation partition, every layer of burning are equipped in every layer of combustion chamber
Room forms U-shaped quirk by commutation partition, and the two ends of U-shaped quirk are equipped with accumulation of heat mouth and gas port on furnace body, fires
Port is connected to purification device.
The advantages of the utility model: not only energy consumption significantly reduces, but also does not have to coke, agglomerates of sintered pellets, only uses coal dust and iron
Fine powder can do direct reduced iron, can realize that green low-carbon is made steel in conjunction with electric furnace steel making, will change from source long at present
Process, the steel that investment is high, energy consumption is high produce traditional pattern；While obtaining the direct reduced iron of low energy consumption, go out from furnace body
Furnace body can be returned after the poor gas purification come, heat is provided for itself reduction, finally realizes charcoal after reducing iron, itself
Almost become CO entirely2Effect, thus greatly reduce the consumption of carbon, and the direct sources of carbon are common coal, rather than
Expensive coking coal.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model main view.
Fig. 2 is the utility model side view.
In figure: 1- furnace body, the combustion chamber 2-, 3- restore room, the gas outlet 4-, 5- temperature partition, 6- commutation partition, 7- accumulation of heat
Mouthful, 8- gas port, 9- feeding warehouse, 10- discharging bin.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As depicted in figs. 1 and 2, a kind of charcoal base directly reducing iron heat accumulating type shaft furnace, including furnace body 1 are set in the furnace body 1
Successively spacing parallel arranging is arranged for combuster 2 and reduction room 3, combustion chamber 2 and reduction room 3, and the feeding warehouse 9 at reduction room 3 and top connects
Logical, reduction room 3 is connected to the discharging bin 10 of bottom, and feeding warehouse 9 is connected to the gas outlet 4 on furnace body 1, and gas outlet 4 and purification fill
Connection is set, the two ends of combustion chamber 2 are equipped with accumulation of heat mouth 7 and gas port 8 on furnace body 1, and gas port 8 and purification device connect
It is logical, it is equipped with reinforcement structure in combustion chamber 2, reinforcement structure interlaced arrangement is equipped with cooling water jecket at discharging bin 10.
The combustion chamber 2 is divided by temperature partition 5 for several layers, is equipped with commutation partition 6 in every layer of combustion chamber 2, and every layer
