本発明はコークス炉における火落ち判定装置に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fire-fall determination device in a coke oven.
°°火落ち“とはコークス炉内に於いて石炭の乾留が完
全に完了したことを表わす言葉で、この火落ち以前には
決してコークスが炉から押し出されることはない。“°°Hitoshi” is a term used to describe the complete completion of carbonization of coal in a coke oven; coke is never pushed out of the oven before this time.
従来、この火落ちの判定については人間が上昇管中間部
に設けられた覗き穴の蓋を少し開いてもれ出るガスの色
を見ることにより推定あるいは確認を行なってきた。Conventionally, this determination of fire failure has been estimated or confirmed by humans by slightly opening the lid of a peephole provided in the middle of the riser pipe and observing the color of the gas leaking out.
しかし、この方法はいわゆる官能検査であり、判定者の
熟練度、感覚の個人差等に大きく左右され、その判定精
度はあまりよくなかった。However, this method is a so-called sensory test, and is largely influenced by the skill level of the judge and individual differences in sensation, and its judgment accuracy is not very good.
本発明はこの火落ちを精度よく判定するために創案した
ものである。The present invention was devised to accurately determine this fire fall.
火落ち以前には上昇管内は乾留中の石炭から出る石炭ガ

上昇管の頂部から上昇管内部を通して炉内のコークス表
層部を覗き込み、その間に存在する気体の光学的な透明
度の変化から火落ち時刻を判定せんとするものである。Before the fire falls, coal gas (which is usually optically opaque inside the riser) from the coal being carbonized passes from bottom to top inside the riser, and from the top of the riser, the surface layer of coke at the bottom passes through the riser. It is difficult to see because it is blocked by a thick layer of gas, but as the amount of gas generated decreases as the end of fire approaches, the surface layer of coke (as the end of fire approaches, the color of the surface layer of coke is already red) can be seen. Take advantage of the fact that
The objective is to look into the coke surface layer in the furnace from the top of the riser tube through the inside of the riser tube, and determine the fire-off time from changes in the optical transparency of the gas that exists between them.
本発明を実施例装置に基づき図面にて詳細に説明する。The present invention will be explained in detail with reference to the drawings based on an example device.
第１図は従来技術で上昇管を含めたコークス炉の一部を
断面をもって示すもので乾留中の石炭１から発生したガ
スは天井部の空洞２を経て上昇管３の内部を下から上に
通過しベンド４内を通ってドライメーン５へ抜ける。Figure 1 shows a cross section of a part of a conventional coke oven including a riser pipe. Gas generated from coal 1 during carbonization passes through a cavity 2 in the ceiling and flows inside the riser pipe 3 from bottom to top. It passes through Bend 4 and exits to Dry Main 5.
上昇管３の上部には蓋６が設けられ、その中心にはボル
ト７とナラｌ−８によりリンク９が取り付けられていて
人間がレバー１０を引くことにより蓋６を自由に開閉可
能な機構になっている。A lid 6 is provided at the top of the ascending pipe 3, and a link 9 is attached to the center of the lid 6 with a bolt 7 and a lug l-8, and a mechanism that allows a person to freely open and close the lid 6 by pulling a lever 10 is provided. It has become.
本発明は第２図に示す如くボルト７の軸心に貫通孔１５
を設けその頂部に光学的に透明な耐熱ガラス１１を同じ
く貫通孔を有する袋ナラＩ・１２を用いて組み込み蓋６
を閉じたまま蓋６の外から上昇管内部が覗き込めるよう
にする。The present invention provides a through hole 15 at the axis of the bolt 7 as shown in FIG.
An optically transparent heat-resistant glass 11 is installed on the top of the lid 6 using a bag neck I/12 having a through hole.
The inside of the riser pipe can be looked into from outside the lid 6 while the lid 6 is closed.
上昇管３内を通過するガス中には多量のタール分が含ま
れており、それが耐熱ガラス１１の内側に付着して見通
しが悪くなるのを防止する為、窒素ガスを蓋６の上面に
設けた穴１３から供給し、二重構造とした蓋の内部１８
、更にポル１〜７に設けた小孔１４を経て、ボルト７に
設けた貫通孔下端１５′から上昇管３内に吹き出させパ
ージを行うようにする。The gas passing through the riser tube 3 contains a large amount of tar, and in order to prevent it from adhering to the inside of the heat-resistant glass 11 and impairing visibility, nitrogen gas is applied to the top surface of the lid 6. The inside 18 of the lid has a double structure and is supplied from the hole 13 provided.
Further, purging is performed by blowing out into the riser pipe 3 from the lower end 15' of the through hole provided in the bolt 7 through the small holes 14 provided in the ports 1 to 7.
而してボルト７の上方に光軸を合わせて赤色光検出器１
６を設置し耐熱ガラス１１を通して測温できるようにし
た。Then, align the optical axis above the bolt 7 and place the red light detector 1.
6 was installed so that the temperature could be measured through the heat-resistant glass 11.
赤色光検出器１６からの出力を記録計１７に記録させた
ところ第３図に示すような結果が得られた。When the output from the red light detector 16 was recorded on the recorder 17, the results shown in FIG. 3 were obtained.
この場合の横軸は経過時間を、縦軸は当該赤色光検出器
の出力電圧レベルすなわち透明度を表わす。In this case, the horizontal axis represents elapsed time, and the vertical axis represents the output voltage level, or transparency, of the red photodetector.
この第３図において点線の位置Ａから透明度は急速に立
ち上がり点線の位置Ｂに至って安定する。In FIG. 3, the transparency rapidly rises from the dotted line position A and reaches the dotted line position B, where it becomes stable.
したがって、たとえばＡ点からＢ点までの間に火落ち判
定基準を設定することも可能である。Therefore, for example, it is also possible to set the fire fall criterion between point A and point B.
このことから本発明装置により火落ちを人間の官能検査
によらず、判定可能であることがわかる。This shows that the apparatus of the present invention can determine whether the fire has fallen off without relying on a human sensory test.
以上述べたように本発明装置によればコークス炉の自動
火落判定に直接結びつくことは言うまでもなく今後のコ
ークス炉管理に有意義なテ゛−夕を与えるものである。As described above, it goes without saying that the apparatus of the present invention is directly linked to the automatic fire failure determination of coke ovens, and provides significant input for future coke oven management.
