Description

A kind of slag stewing device for the stewing slag of heat
Technical field
The present invention relates to a kind of slag stewing device for the stewing slag of heat.
Background technology
In steel-making industry, slag after steel-making generally all carries out the stewing processing of slag heat by slag stewing device, the structure of the slag stewing device using is at present: comprise slag stewing hole, on slag stewing hole, be stamped slag stewing lid, on the sidewall of slag stewing lid, offer gas outlet, slag stewing hole is connected with jet chimney by slag stewing lid sidewall gas outlet. The operation principle of this slag stewing device is: first the slag after steel-making is deposited in slag stewing hole, and then slag stewing cover buckle is cheated to top in slag stewing, then in slag stewing hole, periodically fetch water, thereby reach the object of the cooling efflorescence of slag. The shortcoming of this slag stewing device is: on the one hand, because slag can give out the high-temperature steam that contains the flammable explosive gas such as hydrogen in a large number in cooling procedure, these steam are most of can enter atmosphere through slag stewing lid sidewall gas outlet and jet chimney, but because the density of the flammable explosive gas such as hydrogen is lighter, the flammable explosive gas such as these hydrogen can rise and be gathered in slag stewing lid bottom, in the time that these inflammable and explosive gases are enriched to finite concentration, very easily meet the naked light in slag stewing hole and quick-fried hole occurs, for hidden danger has been buried in safety in production; On the other hand, the sealing between slag stewing lid and slag stewing hole is poor, and the gap dissipation of high-temperature steam between easily cheating from slag stewing lid and slag stewing is gone out and scalded operator.
Summary of the invention
When the object of this invention is to provide a kind of energy good seal performance and can effectively preventing slag stewing, there is a kind of slag stewing device for the stewing slag of heat of quick-fried hole phenomenon.
For achieving the above object, the present invention has adopted following technical scheme: described a kind of slag stewing device for the stewing slag of heat, comprise: slag stewing hole, and bore is the tubaeform slag stewing lid increasing gradually from top to bottom, the heavy caliber air inlet end cap of tubaeform slag stewing lid is cheated top in slag stewing, and the small-bore outlet side of tubaeform slag stewing lid is connected with jet chimney; Be provided with a circle around slag stewing hole and have the aqua storage tank of water, in aqua storage tank, interval is provided with some cushion blocks that are immersed in water, the downward one in edge at tubaeform slag stewing lid heavy caliber inlet end is extended with a circle bulge loop, in the time that tubaeform slag stewing lid covers slag stewing hole downwards, the bulge loop of tubaeform slag stewing lid is just in time against downwards on the cushion block in aqua storage tank, around slag stewing hole, is also provided with water fender.
Further, aforesaid a kind of slag stewing device for the stewing slag of heat, wherein: on slag stewing hole, also arranging can be to purging the nitrogen blowing mechanism of nitrogen in slag stewing hole.
By the enforcement of technique scheme, the present invention has advantages of good seal performance, quick-fried hole phenomenon, safe to use occurs can effectively prevent slag stewing time.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of slag stewing device for the stewing slag of heat of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, described a kind of slag stewing device for the stewing slag of heat, comprise: slag stewing hole 1, and bore is the tubaeform slag stewing lid 2 increasing gradually from top to bottom, the heavy caliber air inlet end cap of tubaeform slag stewing lid 2 is at the top in slag stewing hole 1, and the small-bore outlet side of tubaeform slag stewing lid 2 is connected with jet chimney 3; Be provided with a circle around slag stewing hole 1 and have the aqua storage tank 5 of water 4, some cushion blocks 6 that are immersed in water 4 are installed at the interior interval of aqua storage tank 5, at the edge of tubaeform slag stewing lid 2 heavy caliber inlet ends, downward one is extended with a circle bulge loop 7, in the time that tubaeform slag stewing lid 2 covers slag stewing downwards and cheats 1, the bulge loop of tubaeform slag stewing lid 2 is just in time against downwards on the cushion block 6 in aqua storage tank 1, is also respectively arranged with water fender 8 in three sides in slag stewing hole 1; Contain by employing the sealing structure for water that aqua storage tank 5, cushion block 6, the bulge loop 7 of water 4 form, greatly improved the sealing between tubaeform slag stewing lid 2 and slag stewing hole 1, prevented high-temperature steam cheat 1 from tubaeform slag stewing lid 2 and slag stewing between the outside loss in gap and scald workman; By water fender 8 is set, can prevent from cheating that internal pressure is instantaneous higherly causes water in aqua storage tank 5 to splash out scalding workman, eliminated potential safety hazard in slag stewing process; In the present embodiment, on slag stewing hole 1, also arrange and can cheat to slag stewing the nitrogen blowing mechanism 9 of 1 interior purging nitrogen, the steam that contains the flammable explosive gas such as a large amount of hydrogen producing in stewing slag heat process can not only be blown away from slag stewing hole 1 like this, prevent that the flammable explosive gas such as hydrogen from cheating 1 interior enrichment and quick-fried hole occurs in slag stewing, and because nitrogen is inert gas, further prevent the generation of quick-fried hole phenomenon, greatly improved safety in utilization;
Operation principle of the present invention is as follows:
Slag in slag stewing hole 1 is fetching water in efflorescence cooling procedure, the steam that contains the flammable explosive gas such as hydrogen in a large number that can produce, these steam that contain the flammable explosive gas such as hydrogen can directly upwards enter jet chimney 3 from the small-bore outlet side of tubaeform slag stewing lid 2 upper ends, then discharge through jet chimney 3 together; In the process moving to the small-bore outlet side of tubaeform slag stewing lid 2 upper ends at steam, part steam can diffuse to around the aqua storage tank 5 in slag stewing hole 1, this a part of steam that diffuses to aqua storage tank 5 can be absorbed by the water of aqua storage tank 5, thereby avoids high-temperature steam to cheat 1 outer loss and scald workman to slag stewing; When cheating in the stewing process of slag heat, internal pressure is instantaneous higherly causes water in aqua storage tank 5 outwards to splash, and the water outwards splashing can be blocked by water fender 8, avoids water to splash out and scalds workman; Nitrogen blowing mechanism 9 cheats 1 interior purging nitrogen to slag stewing simultaneously, be purged into the nitrogen in slag stewing hole 1, can not only make the steam that contains the flammable explosive gas such as hydrogen together successfully from discharging slag stewing hole 1, and because nitrogen is inert gas, further prevent that slag stewing hole 1 from the probability in quick-fried hole occurring. The present invention has advantages of can good seal performance, quick-fried hole phenomenon, safe to use occurs can effectively prevent slag stewing time.
