Abstract
The utility model provides a kind of gas furnace cinder cooling device of iron and steel smelting, it includes furnace shell and is sleeved on the combustion chamber in furnace shell, furnace shell bottom is fixed on the fixed station that puzzles in advance by furnace shell support, up big and down small conical cooling bath is provided with below furnace shell, be marked with cooling water in cooling bath, extend bottom combustion chamber and be fixed in cooling bath; The diameter of cooling bath top notch is greater than furnace shell outer circumference diameter, and cooling bath side is provided with inspection frame; Notch place, cooling bath side is provided with slag notch.The cinder of this programme directly enters, not airborne dust, without the need to manually shoveling warm sludge, is pulled out by cinder more after the cooling period from cooling water.The structure of this programme is simple, easy to operate, labour intensity is low, good cooling results, is applicable to various types of coal incinerators.
Description
Technical field
The utility model relates to smelting iron and steel, refers in particular to a kind of gas furnace cinder cooling device of iron and steel smelting.
Background technology
The modern ironmaking overwhelming majority adopts blast furnace ironmaking, adopts direct reduction iron making and electrometal furnace process individually.Blast furnace ironmaking is reduced in blast furnace by iron ore, and the pig iron is smelt in fusing, and this method is easy and simple to handle, and energy consumption is low, with low cost, can produce in a large number.The pig iron is except part is used for foundry goods, and major part is used as steelmaking feed.Owing to adapting to the high grade coke coal worsening shortages of blast furnace process, in succession there is the non-blast furnace ironmaking method with other energy without coke.Direct reduction iron making, in the solid state with gas or solid reductant reduction by ore, lower than at ore melt temperature, be smelt the sponge iron of solid containing a small amount of impurity element or semi-molten state, metallized pellet or granulated iron, as steelmaking feed (also can make the raw material of blast furnace ironmaking or casting).Electrometal furnace process, the electric reduction furnace adopted without shaft, the poor coke (or coal, charcoal) of usable intensity makes reducing agent more.The electrical heating of electric furnace ironmaking replaces part of coke, and available rudimentary coke, but power consumption is large, can only use under, condition that electricity price is cheap sufficient at electric power.Blast furnace ironmaking needs a large amount of heat energy when smelting, coal is now mostly still adopted to carry out heat supply, but coal can produce a large amount of cinder when burning, existing mode is all directly shoveled out by cinder in stove, can produce a large amount of dust when shoveling out, and when shoveling out, temperature is very high, the labour intensity of workman is very large, also need trickle to lower the temperature after shoveling out and prevent resume combustion, poor stability.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure of iron and steel smelting is simple, easy to operate, labour intensity is low, the gas furnace cinder cooling device of good cooling results.
For achieving the above object, technical scheme provided by the utility model is: a kind of gas furnace cinder cooling device of iron and steel smelting, it includes furnace shell and is sleeved on the combustion chamber in furnace shell, furnace shell bottom is fixed on the fixed station that puzzles in advance by furnace shell support, up big and down small conical cooling bath is provided with below furnace shell, be marked with cooling water in cooling bath, extend bottom combustion chamber and be fixed in cooling bath; The diameter of cooling bath top notch is greater than furnace shell outer circumference diameter, and cooling bath side is provided with inspection frame; Notch place, cooling bath side is provided with slag notch.
The center line of described cooling bath and furnace shell, combustion chamber is located along the same line.
Described furnace shell bottom is provided with furnace shell maintenance window.
The utility model is after employing such scheme, and the cinder after burning directly enters in cooling bath by combustion chamber, is cooled by the cooling water in cooling bath, the cinder of this programme directly enters, not airborne dust, without the need to manually shoveling warm sludge, pulls out cinder from cooling water after the cooling period again.The structure of this programme is simple, easy to operate, labour intensity is low, good cooling results, is applicable to various types of coal incinerators.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, the gas furnace cinder cooling device of iron and steel smelting described in the present embodiment includes furnace shell D1 and is sleeved on the combustion chamber D2 in furnace shell D1, furnace shell D1 bottom is fixed on the fixed station D4 that puzzles in advance by furnace shell support D3, up big and down small conical cooling bath D5 is provided with below furnace shell D1, be marked with cooling water in cooling bath D5, extend bottom combustion chamber D2 and be fixed in cooling bath D5; The diameter of cooling bath D5 top notch is greater than furnace shell D1 outer circumference diameter, and cooling bath D5 side is provided with and checks frame D6; Notch place, cooling bath D5 side is provided with slag notch D7.The center line of cooling bath D5 and furnace shell D1, combustion chamber D2 is located along the same line.Furnace shell D1 bottom is provided with furnace shell maintenance window D8.Cinder after burning directly enters in cooling bath by combustion chamber, is cooled by the cooling water in cooling bath, and the cinder of this programme directly enters, not airborne dust, without the need to manually shoveling warm sludge, is pulled out by cinder more after the cooling period from cooling water.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
