It consists of a red hot coke charging port 2 provided at the top, an inert gas blowing port 3 provided at the hopper-shaped bottom 4, and a P-) 5 and cutting devices 6A and 6B provided at the bottom. The interior of the chamber consists of a pre-chamber A, which is the upper half of the chamber in which the red-hot coke is retained, and a cooling chamber B, which is the chamber in which the red-hot coke is extinguished and cooled.

来よりも小断面積の消火炉で従来と同じ量の不活性ガス
を吹き込む場合も同様な問題が生ずる。Recently, dry fire extinguishing furnaces have been made larger in order to improve their fire extinguishing ability. When a dry fire extinguishing furnace is made larger, its fire extinguishing capacity increases approximately in proportion to the square of the cross-sectional area of the furnace, that is, the diameter of the furnace. In this case, the cross-sectional area of the rectangular gas discharge hole 8 must be increased. In order to increase the cross-sectional area of the gas exhaust hole 8, the horizontal side of the gas exhaust hole 8 can only be increased by a length that is linearly proportional to the diameter of the furnace, so the vertical side of the gas exhaust hole 8 must be made longer. Must be. However, if the cross-sectional area of the gas exhaust hole 8 is made narrow in this way and the average flow velocity of the gas flowing through it is increased as in the past, coke will be sucked into the gas exhaust hole 8 along with the exhaust gas, and the gas will be discharged. The problem arises that the gas deposits in the holes 8 and blocks the gas discharge 3 and the holes 8, making it impossible to operate. Further, a similar problem occurs when the same amount of inert gas as before is blown into a fire extinguishing furnace having a smaller cross-sectional area than before.

の吹き上げによる閉塞の原因になっている。FIG. 4 is an enlarged vertical cross-sectional view of a gas discharge hole portion of a conventional fire-extinguishing furnace. As shown in FIG. 4, since the opening end 8a of the gas discharge hole 8 has to be formed into a relatively sloped slope for furnace construction, the coke 17 flows into the gas discharge hole 8, and a fourth As shown in the figure, it is deposited in a triangular cross section. As a result, the flow velocity of the gas passing upward through the deposited layer in the direction of the arrow becomes extremely non-uniform, and a high-speed upward gas flow is generated at the apex a of the triangle. This upward gas flow causes blockages due to coke blowing up.

ている。In order to solve the above-mentioned problems, as shown in a partial vertical cross-sectional view in FIG.
For example, it is possible to reduce the amount of granular coke flowing into the gas discharge hole 8 by dividing it into upper and lower halves.

This caused problems such as increased equipment costs.

布について調べた。The present inventor has conducted extensive research in order to solve the above-mentioned problems and develop a coke dry fire extinguishing furnace in which coke does not flow into the gas exhaust hole and block the gas exhaust hole. The inventor first investigated the flow velocity distribution of exhaust gas flowing through a conventional gas exhaust hole.

As shown by the line connecting points a + b + C in the figure, it has no choice but to form a triangle. Therefore, the exhaust gas suction speed at point a at the top of the triangle is extremely fast (calculated to be infinite).
The exhaust gas suction speed at the other side point is slow. Fifth
In the figure, the dotted curve is from point a to point b of the gas discharge hole 8.
This is the flow velocity of the exhaust gas while reaching the point.

5 was provided and the gas exhaust hole 8 was divided into two into an upper exhaust hole 8c and a lower exhaust hole 8d, and the exhaust gas suction speed was investigated. As a result, as shown by the dotted curve in Figure 2, the maximum flow velocity of exhaust gas becomes as small as it would be without the partition wall 15, and therefore the amount of exhaust gas can be reduced with the same cross-sectional area of the exhaust hole. It has been found that the amount can be increased by about 40%. Furthermore, in order to achieve the above effects, the inclination angle of the gas exhaust hole 8 and the partition wall 15, the height of the partition wall 15, the opening area of the upper exhaust hole 8c and the lower exhaust hole 8d, etc. are important. I understand.

を有するものである。This invention was made based on the above-mentioned knowledge, and includes an annular chamber formed within the wall of the prechamber, and a large number of gas exhaust holes provided at equal intervals in the circumferential direction within the upper end wall of the cooling chamber. The lower part of each of the plurality of gas exhaust holes is partitioned into at least two stages vertically by a partition wall to form an upper exhaust hole and a lower exhaust hole, and each of the plurality of gas exhaust holes includes: In the coke dry fire extinguishing furnace connected to the annular chamber, the inclination angle of the open end of the gas discharge hole facing the inside of the furnace is 60 to 80 with respect to the horizontal line from the lower end toward the reactor core, and the gas discharge hole The inclination angle of the lower hole wall of the hole is 45 to 80 degrees with respect to the horizontal line from its lower end to the outer wall of the furnace, and the partition wall is
The partition wall is inclined substantially parallel to the lower hole wall of the gas discharge hole, and the height of the partition wall is substantially higher than the angle of repose of coke charged into the furnace. It has the following.
次に、この発明を図面を参照しながら説明する。 Next, the present invention will be explained with reference to the drawings.

段に区分されている。FIG. 1 is a schematic vertical cross-sectional view of a gas discharge hole portion showing an embodiment of the present invention, and FIG. 2 is an explanatory diagram showing the flow velocity distribution of exhaust gas in the gas discharge hole portion shown in FIG. 1. As shown in FIGS. 1 and 2, in the present invention, a partition wall 15 is provided at a position approximately half, or approximately 4, of the distance t from point a to point b of the open end 8a of the gas discharge hole 8. , the lower end of the gas exhaust hole 8 is located above and below the upper and lower exhaust holes 8c and 8d.
It is divided into stages.

is 60 to 8 with respect to the horizontal line from the bottom to the core.
It is necessary that the angle is 0°, preferably 70-75. If the inclination angle θ1 is less than 60°, it is impossible to construct a furnace,
On the other hand, if the inclination angle exceeds 800, it becomes difficult to lower the extinguished coke toward the cutting devices 6A, 6B by opening the y-t.

前記傾斜角度が８０を超えると、ガス排出孔８の下部の
横断面積が小さくなり、排ガスの吸引力が低下する問題
が生ずる。The inclination angle θ2 of the lower hole wall 8b of the gas discharge hole 80 needs to be 45 to 80, preferably 55 to 65, with respect to the horizontal line from its lower end to the outer wall of the furnace. When the inclination angle θ2 is less than 45, coke in the exhaust gas sucked into the gas exhaust hole 8 tends to accumulate on the lower hole wall 8b of the gas exhaust hole 8, causing a problem that the gas exhaust hole 8 is clogged. on the other hand,
If the angle of inclination exceeds 80, the cross-sectional area of the lower part of the gas discharge hole 8 becomes small, causing a problem that the suction force for exhaust gas is reduced.

。The inclination angle of the partition wall 15 is the same as that of the lower hole wall 8 of the gas discharge hole 8.
It is necessary to be approximately parallel (±20°) to the inclination angle of b. If the inclination angle of the partition wall 15 is not approximately parallel (±200) to the inclination angle of the lower hole wall 8b of the gas discharge hole 8,
Coke in the exhaust gas tends to accumulate on the partition wall 15.

クスがガス排出孔８内に吹き上げられて、ガス排出孔８
を閉塞することがなくなる。As described above, since the gas exhaust hole 8 is divided into the upper exhaust hole 8c and the lower exhaust hole 8d by the partition wall 15, the maximum flow velocity of the exhaust gas flowing through the gas exhaust hole 8 is lower than that without the partition wall 15. The case becomes smaller. Therefore, the amount of exhaust gas can be increased with a discharge hole having the same cross-sectional area as the conventional one, and the flow velocity distribution of the exhaust gas flowing into the gas discharge hole 8 is averaged, and as a result, the part where the suction velocity is particularly high is reduced, and as a result, the coke is blown up into the gas exhaust hole 8, and the gas exhaust hole 8
will no longer be blocked.

よく、必要以上に高くする必要はない。仕切りＷ１５を
ガス排出孔８の高さ方向全長にわたって設けても、より
以上の効果はなく、かえって、設備費が嵩む問題が生ず
る。The height of the partition wall 15 must exceed the angle of repose of the coke charged into the furnace. If the height of the partition wall 15 is less than the angle of repose of coke, the coke blown up into the upper discharge hole 8c overflows into the lower discharge hole 8d, and the provision of the partition wall 15 has no effect. Partition wall 1
In this way, the height of 5 only needs to exceed the angle of repose of coke, and there is no need to make it higher than necessary. Even if the partition W15 is provided over the entire length of the gas discharge hole 8 in the height direction, there is no further effect, and on the contrary, the problem arises that the equipment cost increases.
上部排出孔８ｃの開口面積は、下部排出孔８ｄの開口面
積よりも大きくした方が好ましい。即ち、ガス排出孔８

が詰りやすい問題を解決することができる。It is preferable that the opening area of the upper discharge hole 8c be larger than that of the lower discharge hole 8d. That is, the gas exhaust hole 8
Inward blowing of coke tends to occur more quickly in the lower discharge hole 8d than in the upper discharge hole 8c. Therefore, if the opening areas of the upper discharge hole 8c and the lower discharge hole 8d are the same, the lower discharge hole 8d may be easily clogged with coke. Therefore, if the opening area of the lower discharge hole 8d is made smaller than the opening area of the upper discharge hole 8c, the height of the maximum exhaust gas flow velocity shown by the dotted line in FIG. can be solved.

は少なくなる。In the above explanation, one partition wall is provided at the gas exhaust hole, but it is not limited to one partition wall, but two or more partition walls may be provided.If the number of partition walls is increased, the exhaust gas suction will be divided into more parts. ,
The amount of granular coke blown up into the gas discharge hole 8 and deposited thereon is reduced.

る等、工業上多くの有用な効果がもたらされる。As described above, according to the present invention, when extinguishing red hot coke in a coke dry fire extinguishing furnace, the flow velocity distribution of the exhaust gas flowing into the gas discharge hole is averaged, and unlike the conventional method, the flow velocity distribution of the exhaust gas flowing into the gas discharge hole is averaged. Therefore, coke will not enter the gas exhaust hole and blow up to block the gas exhaust hole, and since the amount of coke flowing into the gas exhaust hole is extremely small, The pressure of the gas blown into the fire extinguishing furnace body can be lowered, and red-hot coke can be extinguished economically, and many other useful effects can be brought about industrially.
