Description
One. technical field:
The present invention relates to a kind of air-guiding wall and crossbeam of palletizing shaft furnace, particularly relate to a kind of air-guiding wall arch or broken line arch and build brick crossbeam and the blast deflecting wall for vertical pellet furnace built by laying bricks or stones.
Two. background technology:
The powdered iron ore pelletizingization is one of efficient, long-lived, energy-conservation gordian technique of blast furnace ironmaking, must dry after the powdered iron ore pelletizingization, and sintering, shaft furnace are the advanced technologies in the sintering technology.That shaft furnace process has is simple in structure, less investment, thermo-efficiency height, convenient, the operating rate advantages of higher of operating maintenance.The oven dry bed places shaft furnace furnace roof place, the green-ball that has certain particle size during work is carried other shaft furnace top with conveyor, be distributed into continuously, uniformly in the oven dry bed by material distributing machine, the green-ball that enters in the shaft furnace descends with a certain speed, hot gas in the combustion chamber sprays in the stove from burner, carries out heat exchange from bottom to top.Most of cooling air (hot blast) after the heat exchange is by air-guiding wall, converges under the fire grate of oven dry bed with the waste gas (after the heat exchange) of combustion chamber---dry green-ball, draw from fire door then, and through dustproof, feed smoke stack emission.At first process drying and dehydrating preheating oxidation in shaft furnace top oven dry bed of green-ball enters the roasting band then, at high temperature takes place fixed; Through the soaking zone, finish whole consolidation processes; Fixed good pelletizing and bottom blast the cooling air that in the stove rise in the back and carry out heat exchange and obtain cooling; Cold finished pellet of being honored as a queen is discharged from furnace bottom; Finish the whole roasting process of pelletizing.
The oven dry bed mainly is made up of oven dry bed supporting beam and dry the comb.Majority is an individual layer, and only a few is a herring-bone intersection multilayer.Oven dry bed supporting beam all adopts water cooling, is called baking bed water beam, and baking bed water beam is commonly called as Xiao Shuiliang, is that the dry double-edged fine-toothed comb of rest is used, and beam requires to bear 500-600 ℃, and individual cases reach the high temperature of 900 ~ C, simultaneously water-fast vapour and the corrosion of other sour gas; Bear the uniform load of about 1t/m, so the performance of beam, life-span are related to sintering cost, energy consumption and labour productivity.Early stage baking bed water beam is the rectangular configuration with the angle steel welding, and weld seam cracking easily leaks.After change thick-walled seamless steel pipes into, avoided the cracking leak.Baking bed water beam is worked under hot conditions, and adopt water cooling to have following defective: (1) water loss is big, and this problem is along with the anxiety of water resources is more and more outstanding; (2) along with the deposition of incrustation scale, the cooling performance variation causes the wall temperature rising and makes the water beam deflection; 3) when having a power failure suddenly, make the water beam cut off the water supply and burn out; (4) current consumption is big, because the residing position of oven dry bed absolute altitude is very high, increased the water coolant pump lift greatly, the power of water pump, power consumption all increase greatly under the identical condition of the water yield, about in addition 1/3rd heat energy is taken away by water, reduce thermo-efficiency, caused the consumption of thermal waste and water resources.
At this situation, (publication number is CN1600879A to Chinese patent, application number is 200410086129.5) a kind of " high furnace baking bed for sintering ball body of powder of iron ore water free beam " disclosed, the cross section of this beam is combined by the semicircle arch and the bottom rectangle on top, and its centre portions is the reinforcing bar pottery beam body that is combined with the superalloy skeleton (2) of internal layout by the matrix (1) that enhancing toughening ceramic material constitutes; Even coating alumina silicate fibrous insulant (3) plays a role in insulation around the beam body; Thermal insulation material coats stainless refractory steel protective guard (4) outward; surface lacquer Y2O3ZrO2 thermal barrier coating (5); this beam has good heat-resistant, mechanical property and chemical property; replace the weldless steel tube water-cooled beam that present pellet sintering shaft furnace baking bed uses, the cancellation shaft furnace is produced huge pressure water supply cooling system, realizes the waterless operation of Shaft furnace drying bed; reach the minimizing initial cost; the conserve water resource improves energy utilization rate, improves the purpose that product produces matter and quality.But this beam is the straight line cylindricality, and during large span, the intermediary weak strength improves the intensity of whole beam if desired, needs to increase the rugosity of beam, increases cost.
Three. summary of the invention:
Purpose of the present invention: the defective that overcomes prior art, provide a kind of air-guiding wall arch or broken line arch reasonable in design, simple in structure, that intensity is high to build the brick crossbeam of building by laying bricks or stones, and provide a kind of this air-guiding wall arch or broken line arch used to build the brick blast deflecting wall for vertical pellet furnace of building crossbeam by laying bricks or stones, it has cancelled the pressure water supply cooling system of Shaft furnace drying bed bulky complex, has reduced the sintering cost.
