At the lower end of the wind guide wall is provided with a supporting water beam of wind guide wall. One material guide wall is arranged at the lower part of cavity of the furnace body. The material guide wall divides the lower part of furnace cavity into the 1st chamber and 2nd chamber evenly. The utility model has the advantages of high heat efficiency to enhance production utilization factor.
Description
Technical field
The utility model relates to smelting equipment, is a kind of pelletizing shaft furnace with smooth descent and diversion functions.
Background technology
At present, the palletizing shaft furnace that generally uses in each iron and steel enterprise of China generally adopts 8-10m
2Specification, it produces usage factor is 6-7t/m
2H, single stove annual production is up to 600,000 tons, has promptly reached the more advanced level of production in the world.Along with China's needs of economic development, make every effort to single stove annual production and surpass 1,000,000 tons, still, palletizing shaft furnace is more to large scale development, and then its thermal efficiency is relatively low, causes producing usage factor and reduces.China is a unique 16m who built up in 1987 at present
2Palletizing shaft furnace, through for many years use, update, it produces usage factor still at 4.8-4.9t/m
2Fluctuate between the h, its main cause is: shaft furnace maximizes as needs to increase lateral dimension, then the distribution of temperature is difficult to reach rationally effectively in the stove, as increase the short transverse size, then height and temperature aspect are difficult coordinates, and makes discharge not smooth, produces " dead stock column " in the stove of being everlasting, thereby influence the thermal efficiency, it is low to cause producing usage factor.The production usage factor that how to improve large-scale palletizing shaft furnace makes single stove annual production surpass 1,000,000 tons, is one of important topic of studying for a long period of time of those skilled in the art, does not also obtain relevant enlightenment from the technology contents of having reported at present.
Summary of the invention
The purpose of this utility model is, a kind of pelletizing shaft furnace with smooth descent and diversion functions is provided, and makes it have thermal efficiency height, produces the advantage that usage factor improves thereby make.
The utility model is in order to finish goal of the invention, finish by the following technical programs: the utility model comprises body of heater, upper of furnace body is provided with furnace roof baking bed, the body of heater both sides are provided with the combustion chamber respectively, air-guiding wall is set in the body of heater, the air-guiding wall lower end is provided with air-guiding wall and supports the water beam, in body of heater inner chamber bottom the homocline training wall is set at least one, and the homocline training wall is divided at least two the first uniform locellus and second locellus with body of heater inner chamber bottom.Further program of the utility model is: in homocline training wall bottom the homocline training wall is set and supports the water beam.One of the utility model embodiment is: the homocline training wall is arranged on air-guiding wall and supports between water beam and the discharge discaling roll top body of heater base water beam.The utility model further scheme is: the upper width of homocline training wall is greater than its underpart width.The homocline training wall supports the water top surface of the beam and is connected with body of heater with the homocline training wall, and the bottom surface is connected with discharge discaling roll top body of heater base water beam.The homocline training wall is vertical with air-guiding wall support water beam length direction.
After the utility model is provided with training wall, can make the palletizing shaft furnace inner chamber form a plurality of cells, increased the resistance of intermediate stream, slowed down the downstream rate of intermediate stream, make the descending speed of whole charge level keep uniformity as much as possible, materials flow is smooth and easy in the stove, and airflow smooth has simultaneously reduced the resistance that air-flow penetrates the bed of material.
The utility model through the several months good effect that draws on probation is: blanking is fast in the middle of having solved large-scale palletizing shaft furnace, the both sides blanking is slow, make the inefficient deficiency of roasting, materials flow is unimpeded, " dead stock column " phenomenon of having avoided being prone in the stove, gas stream in the stove rises smooth and easy, gap between " stock column of living " pelletizing is big, reduced the resistance that air-flow penetrates the pelletizing bed of material, guaranteed along stove section gas-solid heat exchange abundant, improved the roasting efficient of shaft furnace, the pelletizing finished product that makes production is produced usage factor and has been brought up to 9.53t/m under the prerequisite that reaches the YB/T005-2005 quality standard
2H makes single stove annual production surpass 1,000,000 tons and becomes a reality, for palletizing shaft furnace provides reliable guarantee to large scale development.

The specific embodiment
4 is bodies of heater among the figure, body of heater 4 tops are provided with furnace roof baking bed 3, body of heater 4 both sides are provided with combustion chamber 7 respectively, air-guiding wall 5 is set in the body of heater 4, air-guiding wall 5 lower ends are provided with air-guiding wall and support water beam 6, in body of heater 4 inner chamber bottoms homocline training wall 8 is set at least one, homocline training wall 8 is divided at least two the first uniform locellus 13 and second locellus 14 with body of heater 4 inner chambers 15 bottoms.For example: two roads or three road homocline training walls 8 can be set as required, with uniform three cells or four cells etc. of being divided in body of heater 4 inner chambers 15 bottoms, further to reach the utility model effect.Homocline training wall 8 bottoms are provided with the homocline training wall and support water beam 9, and the setting of homocline training wall 8 also can be supported between water beam 6 and the discharge discaling roll top body of heater base water beam 10 at air-guiding wall.Homocline training wall 8 is a quadrangle, and shown position is set as shown in Figure 1, and its upper width is greater than its underpart width.The homocline training wall supports water beam 9 end faces and is connected with body of heater 4 with homocline training wall 8, and the bottom surface is connected with discharge discaling roll top body of heater base water beam 10, to increase its fastness etc.Homocline training wall 8 is vertical with air-guiding wall support water beam 6 length directions.The utility model shaft furnace is that qualified green-ball is delivered to shaft furnace cloth truck by belt feeder, evenly back and forth be distributed into furnace roof baking bed 3, green-ball is finished oven dry on furnace roof baking bed 3, enter preheating zone, roasting band, the soaking zone of air-guiding wall 5 both sides burner hearths downwards, after preheating, roasting, soaking, arrive air-guiding wall and support water beam 9 bottoms.Air-guiding wall 5 both sides materials flows pool together and enter the salband burner hearth, be provided with homocline training wall 8 in body of heater 4 inner chambers 15 bottoms (also claiming salband herein), pellet enters in the cell that homocline training wall 8 is separated equably, because the existence of this cell structure, make the resistance that each several part is met in the descending process of materials flow equal substantially, make the evenly operation downwards of materials flow section, avoided pellet in the large scale burner hearth, because the little both sides of middle resistance resistance big (near " wall attachment effect " of furnace wall generation), and slow " funnel " effect of blanking fast both sides blanking in the middle of producing.Behind the pellet process homocline training wall 8, enter the discharge discaling roll, the bulk pellet fragmentation that discaling roll forms bonding in the roasting process, the pellet after the fragmentation enters secondary cooling apparatus, further after the cooling, is discharged out of the furnace by hopper.The utility model is not limited among the present embodiment.
