Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
nullSuch as Fig. 1、Fig. 2、Fig. 3、Fig. 4、Fig. 5、Fig. 6、Shown in Fig. 7，Described circulated sprinkling type steel slag hot boils in a covered pot over a slow fire steam technological processing for explosion protection feature device，Including: cheat 1 in order to stack the slag stewing of slag，Seal at the top in slag stewing hole 1 and be stamped slag stewing lid 2，The sidewall of slag stewing lid 2 offers gas outlet，Slag stewing hole 1 is connected with spray column 4 by the jet chimney 3 being connected with slag stewing lid 2 sidewall gas outlet，Spray column 4 is provided with the spraying mechanism of energy shower water downwards，A venthole 5 is at least offered at the top of slag stewing lid 2，Each venthole 5 of slag stewing lid 2 is connected with spray column 4 by gas fairlead 6 respectively，All gas fairlead 6 is all arranged in the trend gradually risen，So can make the retention areas not having the flammable explosive gas such as hydrogen in gas fairlead 6，Guarantee that the flammable explosive gas such as the hydrogen drawn in slag stewing hole 1 successfully can enter spray column 4 along gas fairlead 6，The flammable explosive gas such as hydrogen are prevented to be enriched with in slag stewing hole 1 and gas fairlead 6 and explode，Substantially increase device security energy；The lower wall of spray column 4 offers delivery port, spray column 4 is connected with the import of cooling tower 24 by the first water return pipeline 23 being connected with its delivery port, the outlet of cooling tower 24 is connected with pond 26 by the second water return pipeline 25, and by low-pressure pump and water supply line 27, the spraying mechanism in spray column 4 supplies water in pond 26；In the present embodiment, the structure of described spraying mechanism is: circumferentially distributed in spray column 4 have some straight tubes 7, the endless tube 8 that from up to down interval is connected with all straight tubes 7 while of installing some in spray column 4, every endless tube 8 circumferentially distributed there are some showers 9 being provided with nozzle along it, all straight tubes 7 are connected with pond 26 by low-pressure pump and water supply line 27 simultaneously, above-mentioned spraying mechanism can in spray column water distribution uniformity；In the present embodiment, jet chimney 3 stretches into spray column 4 from the top center of spray column 4, all endless tubes 8 are coated with the jet chimney 3 stretching into spray column 4, so enter the steam-energy of spray column 4 in uniform way by the outwards upwards loss of spray column center from jet chimney 3, the steam-energy moved upward is made to be fully contacted with the shower water from 9 times sprays of shower, thus vapor sorption is processed, this jet chimney 3 is high with the steam treatment effeciency of the arrangement of endless tube 8；nullIn the present embodiment，Jet chimney 3 is provided with explosion-proof valve 12，The structure of described explosion-proof valve is: include the tubular valve body 13 connected with jet chimney 3，Tubular valve body 13 is hinged with the cover plate 14 that can cover downwards tubular valve body 13 upper orifice，Limited block 15 is installed at the hinged end of cover plate 14，When cover plate 14 is flipped up，Limited block 15 at cover plate 14 hinged end is just against on the lateral wall of tubular valve body 13，So when the instantaneous increase of the pressure in jet chimney 3，Some vapor can be expelled directly out jet chimney 3 from the tubular valve body upper orifice of explosion-proof valve 12，Avoid jet chimney 3 and spray column 4 are caused damage，Simultaneously by the design of limited block 15 at cover plate hinged end，It is avoided that cover plate 14 excessive outwards upset because the outside impulse force of steam that is expelled directly out from tubular valve body upper orifice is excessive，Further increase the operation stability of equipment；In the present embodiment, the upper orifice edge of tubular valve body 13 being provided with a rubber weather strip 16, when cover plate 14 covers downwards tubular valve body 13 upper orifice, cover plate 14 is just pressed on rubber weather strip 16, so can improve the sealing of explosion-proof valve further；In the present embodiment, slag stewing lid 2 is sealed by water seal mechanism and covers on slag stewing hole 1, the structure of described water seal mechanism is: slag stewing hole 1 is provided with a circle and is filled with the aqua storage tank 18 of water 17, in aqua storage tank 18, interval is provided with some cushion blocks 19 being immersed in water 17, a circle bulge loop 20 the most integrally it is extended with at the edge of slag stewing lid 2, when slag stewing lid 2 cover downwards slag stewing cheat 1 time, the bulge loop 20 of slag stewing lid 2 is against downwards on the cushion block 19 in aqua storage tank 18, above-mentioned water seal mechanism simple in construction, easy to operate, good airproof performance；In the present embodiment, being respectively arranged with water fender 21 in three sides in slag stewing hole 1, the water that so can prevent in aqua storage tank 18 during slag stewing splashes out and scalds workman, eliminates potential safety hazard；In the present embodiment, also setting up on slag stewing hole 1 can be to the nitrogen blowing mechanism 22 purging nitrogen in slag stewing hole 1, so can preferably the flammable explosive gas such as the hydrogen being enriched in slag stewing hole 1 be blown away from slag stewing hole 1, prevent the flammable explosive gas such as hydrogen to be enriched with in slag stewing hole 1 and explode further, substantially increase equipment safety in operation；In actual applications, use each slag stewing hole to be respectively configured the use pattern of a spray column, and then the unsafe factor that the mutual ribbon of steam being prevented effectively from adjacent slag stewing hole is come, substantially increase safety in utilization.
The operation principle of the present invention is as follows:
Pond 26 is first made to be supplied water by low-pressure pump and the water supply line 27 straight tube 7 in spray column 4, straight tube 7 is supplied water to shower 9 by endless tube 8, shower 9, by the downward shower water of nozzle, is arranged by the cooperation of straight tube 7, endless tube 8 and shower 9, can be made shower 9 water distribution uniformity in spray column 4；Slag in slag stewing hole 1 can give out a large amount of steam containing combustion explosion hazard gases such as hydrogen in efflorescence cooling procedure of fetching water, the flammable explosive gas such as the hydrogen that these steam Midst density are lighter can be to slag stewing lid 2 top movements, and enter gas fairlead 6 from slag stewing lid 2 top venthole 5, enter spray column 4 from gas fairlead 6 again, owing to gas fairlead 6 is in the trend mounting arrangements gradually risen, make hydrogen successfully can enter spray column 4 along gas fairlead 6, without being detained in gas fairlead 6, thus avoid the flammable explosive gas such as hydrogen and be enriched with in slag stewing hole 1 and gas fairlead 6 and explode；Most of steam that slag distributes in efflorescence cooling procedure of fetching water is then through the gas outlet entrance jet chimney 3 of slag stewing lid sidewall, spray column 4 is entered again through jet chimney 3, owing to jet chimney 3 stretches in spray column 4, and endless tube 8 is coated with the jet chimney 3 stretching into spray column 4, so enter the steam-energy of spray column 4 in uniform way by the outwards upwards loss of spray column center from jet chimney 3, the steam-energy moved upward is made to be fully contacted with the shower water from 9 times sprays of shower, thus this some vapor in entering spray column 4 through jet chimney 3 is disposed completely, simultaneously, this some vapor entering spray column 4 from gas fairlead 6 also can be fully contacted and adsorbed process with the shower water of 9 sprays of shower；Can accumulate in bottom spray column 4 after spray column 4 condensation process and enter the first water return pipeline 23 from the delivery port of spray column 4 lower wall, entering cooling tower 24 through the first water return pipeline 23 again to cool down, the backwater after the cooling of cooled tower 24 enters pond recycling through the second water return pipeline 25 again.The present invention have the steam that steel slag hot produces after stewing can be effectively treated and can effectively prevent the flammable explosive gas such as the hydrogen produced during slag stewing in slag stewing hole enrichment and there is the advantage exploded.
