度が低いため、臭気苦情の解消が図れることとなる。Generally, an aqueous reaction that generates H and S is said to occur when water vapor is added to a carbon material at a temperature of 1000°C or higher. According to the first method of the present invention, the simultaneous watering is carried out on red-hot coke whose temperature has been lowered to 1000°C or less by preliminary watering, so that aqueous reactions are less likely to occur;
The amount of HtS generated is significantly reduced. Pre-watering is 10
This is carried out on red-hot coke that maintains a high temperature of 00'C or higher, but since this is a very short-time water sprinkling, the amount of ■1□S generated by the aqueous reaction is small. therefore,
Even if the water vapor generated during pre-spraying and simultaneous watering is released into the atmosphere from the top of the fire extinguishing tower, H, Si4
Since the degree of odor is low, odor complaints can be resolved.

なる。In addition, as in the second method of the present invention, when the entire red-hot coke is partially extinguished by water spray, the extinguishing area per hour becomes smaller, and the range in which the aqueous reaction occurs becomes smaller. The peak value of the amount of H and S generated per hour decreases.Therefore, since the landing concentration is proportional to the amount generated per hour, the landing concentration also decreases by the amount that the peak value decreases, and in this case as well, odor complaints are caused. It will be possible to resolve the issue.
以下、本発明の詳細な説明する。The present invention will be explained in detail below.

間制御できるようにしである。As shown in Fig. 2, the water sprinkler pipes 3 are arranged in the shape of a lattice frame, and the surrounding area of the red-hot coke 4 is extinguished by spraying water from the frame 3', and the water from the plurality of lattice parts 3'' is extinguished. The central part of the red-hot coke 4 is extinguished by water spraying, and the entire red-hot coke 4 is extinguished completely.A water supply pipe 6 is connected to the water supply pipe 3, and an electric valve is connected to the water supply pipe 6. 7 is provided. This electric valve 7 switches between supplying and stopping water to the sprinkler pipe 3, and the opening and closing of the valve can be time-controlled by a timer 8.

すなわち、赤熱コークス４に対する散水を、事前散水と
一斉散水の前後２回に分けて行うのである。That is, the red-hot coke 4 is sprinkled with water twice: before and after the preliminary watering and the simultaneous watering.

It was set to about 1/10. Also,
The standing cooling time T2 required from the stop of preliminary watering to the start of simultaneous watering was about 5 to 30 seconds, and the watering time T required from the start to stop of simultaneous watering was about 50 to 60 seconds.

, the peak concentration of S is the peak concentration of H in the conventional method (indicated by
It was about 30% lower than the tS peak concentration, and it became clear that the method of the present invention is a fire extinguishing method that hardly generates H7S.
次に、本発明の第２の方法は、前記第１の方法で説明し

でき、るのである。That is, the water sprinkler pipe 3 arranged above the fire extinguisher 2 is formed by arranging a plurality of independent rectangular pipes 31 to 34 in parallel in the longitudinal direction of the fire extinguisher 2. These rectangular tubes 3, -3. In each case, there are independent water supply pipes 61 to 64 connected to the main water supply pipe 6'.
are connected to each water supply pipe, and a timer 8 similar to the above is connected to each water supply pipe. ~Electric valve 71 whose opening/closing can be controlled by time at ~84~
74 are provided. Therefore, each rectangular pipe 3 configuring the water sprinkler pipe 3. ~3. The red hot coke 4 can be sprinkled with water independently and at different times.

Set the opening/closing time of the electric valve 7□ on the timer 8t of the rectangular pipe 3□, and then set the opening/closing time of the electric valve 7□ on the timer 8t of the rectangular pipe 3□. Timer 8. Set the opening/closing time of electric valve 7,
Finally, rectangular tube 3. The timer 84 of the electric valve 7. The opening and closing times are set so that watering is performed in the watering pattern shown in FIG. That is, first, the red hot coke 4 loaded at the tip of the fire extinguisher 2 is extinguished by water spraying from the rectangular pipe 31, and then the rectangular pipe 3! The red-hot coke loaded in the center front half of the fire extinguisher was extinguished by water spray from the rectangular pipe 3. The red-hot coke loaded in the rear center portion of the fire extinguisher is extinguished by water spray from the rectangular pipe 34, and finally the red-hot coke loaded in the rear end of the fire extinguisher is extinguished by water spray from the rectangular pipe 34. .

え時間Ｔ８として０．５〜１秒の間を置くようにした。In the illustrated example, the watering time T from the start to the stop of watering for each rectangular pipe 31 to 34 is approximately 25 to 30 seconds, and the valve is switched from the stop of watering for the previous rectangular pipe to the start of watering for the next rectangular pipe. The time T8 was set to be between 0.5 and 1 second.
なお、各矩形管３１〜３４当りの散水時間Ｔは、通常の
一斉散水よりも短くなるので、消火不良が生じないよう
散水量を適宜調整する必要がある。In addition, since the water sprinkling time T per each rectangular pipe 31-34 is shorter than normal simultaneous water sprinkling, it is necessary to adjust the amount of water sprinkling suitably so that inadequate fire extinguishing does not occur.
また、各矩形管３．〜３４からの散水は、図示例のよう
