Description
Technical field
The utility model relates to smelting iron and steel, refers in particular to a kind of gas furnace dust arrester 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, and mostly existing or employing coal carries out heat supply, but coal can produce a large amount of dust when burning, and the heat energy with dust enters the quality that smelting furnace can affect matallurgical products.
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, the gas furnace dust arrester of good dedusting effect.
For achieving the above object, technical scheme provided by the utility model is: a kind of gas furnace dust arrester of iron and steel smelting, it includes dedusting frame, gas wash tower, dedusting pond, wherein, gas wash tower is packed on the ground of combustion furnace side by dedusting frame, side, gas wash tower top is connected with the heating tube of combustion furnace, gas wash tower top opposite side is connected on main heating tube by heat supply looped pipeline, gas wash tower bottom is funnel-shaped structure, funnel bottom is provided with dust guide pipe vertically downward, bottom dedusting frame, subsurface has dug dedusting pond, extend in dedusting pond bottom dust guide pipe, dedusting is marked with water in pond.
Described gas wash tower top is provided with dividing plate, and dividing plate is between combustion furnace heating tube and heat supply looped pipeline.
The rectangle hole that described dedusting pond is dug by subsurface is formed, and dedusting frame is fixed on one end, dedusting pond.
The utility model is after employing such scheme, the hot blast of combustion furnace is by keeping off by dividing plate one during gas wash tower, dust is declining under gravity, drop down onto in dedusting pond by dust guide pipe, water in dedusting pond forms water seal, prevent the dust fallen from flying upward, when dust accumulation is to certain procedures, dig out by dedusting pond.The structure of this programme is simple, easy to operate, good dedusting effect, energy-conservation, be conducive to environmental protection.
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 dust arrester of iron and steel smelting described in the present embodiment includes dedusting frame B1, gas wash tower B2, dedusting pond B3, wherein, gas wash tower B2 is packed on the ground of combustion furnace side by dedusting frame B1, side, gas wash tower B2 top is connected with the heating tube of combustion furnace, gas wash tower B2 top opposite side is connected on main heating tube by heat supply looped pipeline B4, gas wash tower B2 bottom is funnel-shaped structure, funnel bottom is provided with dust guide pipe B5 vertically downward, bottom dedusting frame B1, subsurface has dug dedusting pond B3, the rectangle hole that dedusting pond B3 is dug by subsurface is formed, dedusting frame B1 is fixed on B3 one end, dedusting pond, extend in the B3 of dedusting pond bottom dust guide pipe B5, in the B3 of dedusting pond, be marked with water.Gas wash tower B2 top is provided with dividing plate, and dividing plate is between combustion furnace heating tube and heat supply looped pipeline B4.The combustion furnace hot air of the present embodiment is by keeping off by dividing plate one during gas wash tower, and dust is declining under gravity, drops down onto in dedusting pond by dust guide pipe, water in dedusting pond forms water seal, prevent the dust fallen from flying upward, when dust accumulation is to certain procedures, dig out by dedusting pond.
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.
