Abstract
The utility model discloses a duct-type air blast device with even airflow distribution for a hot-blast furnace, and is characterized in that the airflows of the air blast quantity can be evenly distributed at the cross-section of a regenerator through extending a cold air duct to the furnace wall which is opposite to a cold air entrance which is arranged on the lower portion in the hot-blast furnace, the device comprises the cold air duct which is arranged outside the furnace, a duct which is extended to the internal portion of the furnace, and a duct fixing block which is arranged in the furnace, and the duct which is extended to the internal portion of the furnace is mounted between grate props which are arranged on the lower portion in the furnace for passing through a furnace axis, one to five annular throat rings are mounted in the duct which is internally divided into one to five sections, core vents which are evenly distributed are arranged on the wall surface of the duct, and the end face of the duct is enclosed. The air blast quantity is evenly distributed at the cross-section of the regenerator by the utility model, the heat is fully transferred in the regenerator, the utilization rate of a heat storage is enhanced, and the regenerator is prevented from unevenly sinking.
Description
Technical field
The utility model relates to the blast funnace hot blast stove technical field, and concrete is a kind of device to the even air blast of hotblast stove.
Background technology
In the hotblast stove air-blast device, entrance places on the big-wall of hotblast stove at present, generally is an inlet or two inlets.Because gas blower pressure is higher and exit velocity is bigger, under the effect of air mass force, makes hotblast stove bottom fire grate space air blast inequality, blast entrance opposite air quantity is big often, and the ingress air quantity is little.Its result causes blast volume at regenerator transverse section skewness, and the interior heat exchange of regenerator is insufficient, and the heat storage utilization ratio is not high, even makes the regenerator uneven subsidence.
In order to overcome the air blast inequality, existing patent documentation has been announced some solutions.Chinese patent as publication number CN1017627B proposes to distribute not simultaneously when the fire grate pillar, and the shape of baffle plate and placement location should change, but the riding position of baffle plate is poor to different hotblast stove versatilities with shape.Publication number is that the Chinese patent proposition cold wind current equalizer of CN2380576Y and CN2736365Y is arranged in around the big-wall of hotblast stove bottom fire grate pillar, and this scheme is owing to be difficult on the complex structure engineering realize.
The utility model content
The purpose of this utility model is by cold air duct being extended to the furnace wall place, cold air inlet opposite of bottom in the hotblast stove, blast volume being evenly distributed at regenerator transverse section air-flow.
The purpose of this utility model is achieved in that
Hotblast stove comprises with the air-blast device that ducted air is evenly distributed: the outer cold-air duct road of stove, extend to pipeline, stove interior conduit fixing catch in the stove, the pipelining that extends in the stove is propped up intercolumniation at the lower furnace fire grate, pass the stove axis, adorn one to five annular restrictor ring in the pipeline, be divided into one to five section in the pipeline, open equally distributed production well on tube wall, the pipeline end face is shut.
The pipeline that extends in the stove can be an equal diameter, also can be that pipe diameter shrinks gradually in stove, and also shrink gradually in the built-in restrictor ring of corresponding pipeline aperture.By throttle plate pipe is divided into interconnective section, at every section tube surface, according to the stove transverse section of pipeline section correspondence or the lower space of stove, offers the aperture that number does not wait, the flow of every sector hole mouth and pairing transverse section or space are proportional.In order to prevent the displacement of stove interior conduit, it is fixed on the furnace foundation by fixing catch.
The utility model is compared with the air-blast device that ducted air distributes with existing hotblast stove, blowing line is extended in the stove, make blast volume uniform distribution on the regenerator transverse section, heat exchange is abundant in the regenerator, the heat storage utilization ratio improves, and has prevented the regenerator uneven subsidence.
Description of drawings
Fig. 1 is the air-blast device vertical view synoptic diagram that hotblast stove is evenly distributed with ducted air; Fig. 2 is the air-blast device side-view synoptic diagram that hotblast stove is evenly distributed with ducted air.
Embodiment
As shown in Figure 1 and Figure 2, hotblast stove comprises with the air-blast device that ducted air is evenly distributed: the outer cold-air duct road 1 of stove, extend to pipeline 2, stove interior conduit fixing catch 6 in the stove, extend between the fire grate pillar 5 of the pipelining bottom in stove in the stove, pass the stove axis, its terminal point is near the big-wall or the partition wall on cold air inlet opposite.Adorn three annular restrictor rings 4 in the pipeline, be divided into four sections in the pipeline, open equally distributed production well 3 on tube wall, the pipeline end face is shut.The stove interior conduit is fixed on the furnace foundation on 7 by fixing catch 6.
Claims (2)
1. air-blast device that hotblast stove is evenly distributed with ducted air, this device comprises: the outer cold-air duct road of stove, extend to cold air duct, stove interior conduit fixing catch in the stove, extend to pipelining in the stove in stove between bottom fire grate pillar, pass the stove axis, adorn one to five annular restrictor ring in the pipeline, be divided into one to five section in the pipeline, open equally distributed production well on tube wall, the pipeline end face is shut.
2. the air-blast device that hotblast stove according to claim 1 is evenly distributed with ducted air, it is characterized in that the pipe diameter that extends in the stove is identical, perhaps in stove, pipe diameter shrinks gradually, and also shrink gradually in the built-in restrictor ring of corresponding pipeline aperture.
