る。 FIG. 1 shows an example of a conventional device. In the figure, molten slag 2 flowing through a gutter 1 is crushed into fine particles by high-speed air generated by a crushing blower 3 and an air nozzle 4. While scattering inside the blasting hood 5, it exchanges heat with the air inside the blasting hood 5, is cooled and solidified, and becomes a high-temperature granular slag 6.
becomes. On the other hand, the air inside the crushing hood 5 is heated by the slag and is discharged to the outside as the crushing high temperature air 7. The high temperature granular slag 6 is in a high temperature state of about 1000° C. and still has a considerable amount of heat, and is temporarily stored in a storage tank 9 by a transfer device 8.

連続的に得られるようになつている。 Since molten slag is normally discharged (slag) intermittently from a blast furnace, converter furnace, or electric furnace, the flow of slag before the storage tank 9 is intermittently operated in accordance with the slag discharge, and the slag in the storage tank 9 is intermittently operated. The high temperature granular slag 6 is stored, and from then on, continuous operation is performed as follows. That is, the high-temperature granular slag 6 stored in the storage tank 9 is continuously introduced into the heat exchanger 10 in a predetermined amount, and heat is exchanged with the cold air 11 from the fan 13 in the heat exchanger 10 in a countercurrent manner. 〓〓〓〓
The cold air 11 is heated by exchanging heat with the high-temperature granular slag 6, and high-temperature air 14 is continuously obtained. There is.

いう欠点が生じることになる。 In the above-mentioned conventional apparatus, high-temperature granular slag 6 is obtained by wind crushing, and heat is continuously recovered in the process from the storage tank 9 onward. Since the operation of the part) is intermittent, the crushed high-temperature air 7 comes out intermittently. Even if high-temperature air 7 is obtained intermittently from the blasting hood 5 in this way, the reality is that it is difficult to use it as a factory (such as a steelworks), and therefore, the blasting high-temperature air 7 remains unused. is released into the atmosphere. Therefore, the temperature of molten slag 2 varies depending on the type of slag and each factory, but
Since the temperature of the high-temperature granular slag 6 is about 1000 to 1100°C, there was a problem in that the heat corresponding to the temperature drop was not recovered. In addition, protection of the material of the wind crushing hood 5,
If a refractory material or a heat insulating material is pasted inside the wind crushing hood 5 for the purpose of reducing heat dissipation, the air temperature inside the wind crushing hood 5 will rise and the granular slag will not be sufficiently cooled. This results in a disadvantage that the granular slag 6 collected at the discharge port is likely to re-fuse.

, but with a top wall 25, both side walls 26, a bottom wall 27 and a rear wall 28 forming a box-shaped blasting hood.
Water tube group 35 arranged in the casing 36 on the inner surface of
are arranged so as to surround the high-temperature granular slag S that is scattered in the wind crushing hood by wind crushing,
The water tube group 35 is in a state where it easily receives radiant heat from the granular slag S. In other words, it is well known that radiant heat is largely controlled by the surface area of the heat transfer surface, but when molten slag is reduced to fine particles (approximately 1 to 2 mmφ) by wind crushing, the surface area of the slag increases. will increase significantly, and since the granular slag S is scattered in the space inside the blasting hood, its radiant heat will be effectively transmitted to the water tube group 35. In addition, this part is a high temperature area of 1000℃ or more, but since heat transfer by radiation increases exponentially as the temperature rises, even more effective heat transfer is possible at the water tube group 35.
It is done through. Furthermore, the heat transfer from the granular slag S to the water tube group 35 is not only due to radiation; some of the granular slag S scattered in the blasting hood collides with the water tube group 35 and transfers heat to the water tube group 35 ( (heat exchange). In particular, since there is granular slag that falls and accumulates on the water tube group 35 of the bottom wall 27, heat transfer to the water tube group 35 by direct contact is increased. However, the arrangement of the water tube group 35 on the inner surface of the bottom wall 27 must be considered so as not to become an obstacle to the movement of the granular slag S toward the discharge port 33 side. Furthermore, the temperature of the air inside the wind crushing hood increases due to heat exchange between the granular slag S and the air inside the wind crushing hood, but the high temperature air is cooled by convective heat transfer with the water tube group 35 and then exits from the exhaust port 34. The air is discharged to the outside, and conversely, the water tube group 35 receives heat from the high-temperature air and recovers the heat.

5. The water pipe group 35 on the inner surface of the side wall 26, bottom wall 27, and rear wall 29 sufficiently recovers the heat of the granular slag S, and sends it to the drum 29 by the water supply pump 30, from which water supply pipes a and b are connected. The water flowing through the tubes of the water tube group 35 is turned into steam. The steam is then returned to the drum 29 via the steam distribution pipes c, d, and e, where it is separated into steam and water.
1. The steam 31 extracted in this way is intermittent because the slag of the molten slag 22 is intermittent, but if it is connected to an existing large-capacity factory steam system or an accumulator is installed, , there are almost no problems in using the steam 31.

うなことがない。 In addition, in this case, the granular slag S colliding with the water tube group 35 exchanges heat with the water flowing through the pipes of the water tube group 35 and is cooled, so that the temperature decreases.
5, and the granular slag S is strongly cooled through the water tube group 35 by radiation, contact, convection, etc. as described above, so that the granular slag collected at the discharge port 33 is There is no possibility of mutual fusion.
