Description

本発明は、石炭粒子からコークスを製造するコークス炭化炉の昇温用ドア（炉蓋）に関するものである。  The present invention relates to a temperature rising door (furnace lid) of a coke carbonization furnace that produces coke from coal particles.

技術背景Technical background

コークス炭化炉に装入された石炭粒子の乾留処理を終えて製造されたコークスを取出（窯出し）する毎にコークス炭化炉の出入口を開閉する炭化炉蓋は、頑丈な鉄骨炉蓋フレーム構造体に大型耐火煉瓦を内張りして耐熱性を確保し、さらに炉蓋フレーム構造体と大型耐火煉瓦との間に炉口枠を押圧し出入口を閉塞する耐熱金属のシールプレートを設けて炉内ガスの漏洩を防止する密封構造に製作されている。しかしながら、耐火煉瓦が高温度の乾留熱を吸収するため、炉蓋付近に装入された石炭粒子が充分に乾留されず、不良コークスが多く窯出しされる問題があった。  The carbonization furnace lid that opens and closes the inlet / outlet of the coke carbonization furnace every time the coke produced after the carbonization process of the coal particles charged in the coke carbonization furnace is taken out (taken out of the kiln) is a sturdy steel furnace lid frame structure A large refractory brick is lined to ensure heat resistance, and a heat-resistant metal seal plate is installed between the furnace lid frame structure and the large refractory brick to close the entrance and exit by pressing the furnace port frame. It is manufactured in a sealed structure that prevents leakage. However, since the refractory brick absorbs high-temperature dry distillation heat, coal particles charged near the furnace lid are not sufficiently dry-distilled, and there is a problem that a lot of defective coke is discharged.

この様な問題に対処して開発されたのが、特公平３−４００７４号公報や特公平５−３８７９５号公報などで紹介される様に、炉蓋フレーム構造体の炭化炉側に熱伝導性金属隔壁で分離された垂直な炉内ガス通路に小さな炉内ガス導入孔を設けた炭化炉蓋、さらに該炉内ガス通路に空気や酸素を吹き込むノズルを設けた炭化炉蓋である。この様な炭化炉蓋は、上記した耐火煉瓦を内張りした炉蓋に較べ、炉蓋付近に装入された石炭粒子の乾留速度を速め不良コークスの発生を少なめる効果を有するが、実用化に至っていない。その理由は明らかにされないが、本発明者らの推測によると、薄鋼板で組み立てられた隔壁体が炉蓋を開閉する毎に急熱急冷の熱サイクルの影響を受けて変形する問題、変形した隔壁体が耐火物構造のコークス炭化炉壁を擦り落とす問題、擦り落された耐火物の破片が窯出しされる乾留コークスに混ざり込む問題、石炭粒子から舞い上がる石炭微細粒子が小さな炉内ガス導入孔に堆積しまたタール化して炉内ガスの導入を停止するなど、コークス生産に支障を来す多くの問題があったものと思われる。  As introduced in Japanese Patent Publication No. 3-40074 and Japanese Patent Publication No. 5-38795, it has been developed to cope with such a problem. A carbonization furnace lid provided with a small furnace gas introduction hole in a vertical furnace gas passage separated by a metal partition wall, and a carbonization furnace lid provided with a nozzle for blowing air or oxygen into the furnace gas passage. Such a carbonization furnace lid has the effect of increasing the dry distillation rate of coal particles charged in the vicinity of the furnace lid and reducing the occurrence of defective coke compared to the furnace lid lined with the above-mentioned refractory bricks. Not reached. The reason for this is not clarified, but according to the inventor's estimation, the problem that the bulkhead assembled with thin steel plates deforms due to the influence of the rapid and rapid thermal cycle every time the furnace lid is opened and closed is deformed. The problem that the bulkhead scrapes the coke carbonization furnace wall with the refractory structure, the problem that the scraped pieces of refractory are mixed into the dry distillation coke, the coal fine particles rising from the coal particles are small in the furnace gas introduction hole It seems that there were many problems that hindered the production of coke, such as the accumulation of gas in tar and targing and the introduction of gas in the furnace was stopped.

これらの問題を解消した炉蓋が、例えば特開２００４−１８８５２号公報や特開２００４−９９８５９号公報で紹介される様に、「炉蓋構造体の断熱ボックスに、炉高方向を複数段に分割する位置に設けた横体支持枠の上下離隔間に石炭粒子遮蔽用の耐熱金属製短冊板を左右に通気間隙を設けて縦横に並列しかつ着脱自在に吊設して構成したコークス炉内ガス回遊隔離室を設けた、コークス炭化炉用昇温炉蓋」である。
特公平３−４００７４号公報 特公平５−３８７９５号公報 特開２００４−１８８５２号公報 特開２００４−９９８５９号公報 For example, as disclosed in Japanese Patent Application Laid-Open No. 2004-18852 and Japanese Patent Application Laid-Open No. 2004-99859, a furnace lid that solves these problems is described as follows. Inside a coke oven constructed with heat-resistant metal strips for shielding coal particles between the top and bottom of the horizontal support frame provided at the position to be divided, with ventilation gaps on the left and right, and parallel and vertically detachable This is a heating furnace lid for a coke carbonization furnace provided with a gas recycle isolation chamber.

発明を解決しようとする課題Problems to be solved by the invention

そこで本発明者らは、コークス炭化炉用昇温炉蓋のコークス炉内ガス回遊隔離室すなわち炉内ガス燃焼室において、正圧域での炉圧変化から正圧域と負圧域を交互に繰り返しながら変動し徐々に低圧化する炉況の中で、炉内ガス燃焼室の炉圧変化を高感度に捉え炉内ガス燃焼室が負圧時に、コークス炭化炉から流入した不完全燃焼（未燃焼）の炉内ガスが燃焼するに必要な量の空気を、電気的制御に依らず機械的動作で、送給するノズルを付設したコークス炭化炉蓋を先に開発した。さらに本発明者らは、このノズルを炉内ガス燃焼室に流れ込んだ未燃焼の炉内ガスを燃焼させる必要な量の空気を長期間安定して確実にかつ迅速に送給する構造に改善すると共に、燃焼で上昇した該炉内ガス燃焼室の高温度の熱で炉蓋側に装入された石炭粒子を加熱促進せしめ、同時に炉蓋の底部または側面部で発生するタールも燃焼熱で分解焼失させるコークス炭化炉用昇温炉蓋を提供するものである。  In view of this, the present inventors alternately changed the positive pressure region and the negative pressure region from the change in the furnace pressure in the positive pressure region in the coke oven gas recirculation isolation chamber of the heating furnace lid for the coke carbonization furnace, that is, the in-furnace gas combustion chamber. In the state of the furnace that fluctuates repeatedly and gradually decreases in pressure, the incomplete combustion that has flowed in from the coke carbonization furnace when the pressure in the furnace gas combustion chamber is negatively detected with high sensitivity is detected. We developed a coke carbonization furnace lid equipped with a nozzle that delivers a quantity of air necessary for combustion of the gas in the furnace (combustion) by mechanical operation regardless of electrical control. Furthermore, the present inventors improve the structure in which a necessary amount of air for burning the unburned in-furnace gas flowing into the in-furnace gas combustion chamber is stably and quickly delivered for a long period of time. At the same time, the coal particles charged to the furnace lid are heated by the high-temperature heat of the gas combustion chamber in the furnace that has risen due to combustion, and at the same time, tar generated at the bottom or side of the furnace lid is also decomposed by the combustion heat. The present invention provides a temperature rising furnace lid for a coke carbonization furnace to be burned off.

An air suction pipe serving as an outlet is provided in the isolation chamber on the other side, and a lower side is used as an intake air outlet that communicates with an in-furnace gas combustion chamber provided on the coke carbonization furnace side of the carbonization furnace lid, and an upper side is an intake air inlet An intake air delivery pipe or an intake air delivery cup having an intake air vent hole formed on the upper side of the side wall is provided through the bottom plate of the air chamber so as to protrude into the air chamber. A large-diameter downward outer cup that forms a gas stagnation space in the furnace is attached to the upper side of the intake air delivery pipe or the intake air delivery cup, and is detachable from the intake air discharge port of the air suction pipe. A coil spring that is placed on the outer periphery of the air suction pipe and is compressed by its own weight is placed on the bottom plate of the air chamber or on a mount, and the intake air discharge port of the air suction pipe An obstruction valve plate lifting guide frame is installed above the obstruction valve plate elevating guide frame surrounding the intake air flow guide plate at a position separated from the air suction pipe via a coil spring.

発明の効果The invention's effect

本発明のコークス炭化炉用昇温炉蓋は、炉内ガス燃焼用空気送出量制御ノズルがコークス炭化炉で発生し炉内ガス燃焼室に流れ込んだ未燃焼性炉内ガスを燃焼させるに必要な量の空気を全て機械的動作で炉内ガス燃焼室に送給するため、保全管理が簡便であり、過剰な量の空気の送給による炉内ガス燃焼室の温度降下と石炭粒子の焼き過ぎ（灰分化）を防止する効果を有する。また炉内ガス燃焼室の一瞬の高圧変化で該炉内ガス燃焼室から吸引空気送出パイプを経て空気チャンバーに逆流する炉内ガスに含まれる石炭やタールなどの浮遊粒子は、ガス昇降流通ガイド板の減圧（減速）作用によって、吸引空気送出パイプまたは吸引空気送出カップの取付側隔離室で分離されるため、空気吸引パイプ側が汚染される事がなく、空気吸入量を制御する閉塞弁板が円滑に作動し、炉内ガスが燃焼するに必要な空気を炉内ガス燃焼室に長期間安定して送給し、炉蓋付近の石炭粒子の乾留を速める効果を有する。  The temperature raising furnace lid for the coke carbonization furnace of the present invention is required for burning the unburned in-furnace gas generated by the air delivery amount control nozzle for in-furnace gas combustion generated in the coke carbonization furnace and flowing into the in-furnace gas combustion chamber. Since all the amount of air is sent to the in-furnace gas combustion chamber by mechanical operation, maintenance management is simple, the temperature drop in the in-furnace gas combustion chamber due to the excessive amount of air feeding and overcoaling of the coal particles It has the effect of preventing (ash differentiation). In addition, suspended particles such as coal and tar contained in the in-furnace gas that flows back from the in-furnace gas combustion chamber to the air chamber through the suction air delivery pipe due to a momentary high-pressure change in the in-furnace gas combustion chamber Because of the pressure reduction (deceleration) action, the suction air delivery pipe or suction air delivery cup is separated from the mounting side isolation chamber, so that the air suction pipe side is not contaminated, and the closing valve plate that controls the air suction amount is smooth. The air required to burn the gas in the furnace is stably supplied to the gas combustion chamber in the furnace for a long period of time, and has the effect of accelerating the dry distillation of the coal particles near the furnace lid.

Reference numeral 19 denotes an air chamber. The air chamber 19 is a sealed box in which a bottom plate 20, a top plate 21, and a side plate 22 are assembled in a box shape having an arbitrary hollow cross section such as a hollow rectangular cross section or a cylindrical cross section. An air amount control device that sucks in an amount of air necessary for burning unburned furnace gas that has flowed into the combustion chamber 13 and supplies the air to the furnace gas combustion chamber 13 is incorporated. The air chamber 19 is provided with a gas raising / lowering flow guide plate 23 at an arbitrary position to provide an isolation chamber A and an isolation chamber B that divide the chamber into left and right, and a lower side of the one isolation chamber A (or B). Is connected to the in-furnace gas combustion chamber 13 on the other side of the isolation chamber B (or A). An intake air delivery pipe 29 having an intake air inlet 28 on the upper side and an intake air delivery pipe 27 on the lower side as shown in FIG. 3 and an intake air delivery port 27 communicating with the in-furnace gas combustion chamber 13 as shown in FIG. An intake air delivery cup 31 having a lower opening with an intake air vent hole 30 formed on the upper side is provided so as to penetrate the bottom plate 20 of the air chamber 19 and protrude into the air chamber 19. When the in-furnace gas combustion chamber 13 is at a high pressure, the gas up-and-down flow guide plate 23 is separated from the in-furnace gas combustion chamber 13 through the suction air delivery pipe 29 in the isolation chamber B or the intake air delivery cup 31 to the air suction pipe in the isolation chamber A. While reducing the pressure in the furnace gas flowing back to 26, the suspended particles such as coal and tar mixed in the furnace gas are dropped into the suction air delivery pipe and the isolation chamber B to be separated, removed and cleaned.

Further, the gas flow dam plate 32 is a gas in which strip materials such as a flat cross section, an arc cross section, and a wave cross section are combined in the same shape or an arbitrary composite shape, and the gas in the furnace flows while meandering up and down in the air chamber 19. It is provided on the ascending / descending flow guide plate 23.

さらに本発明においては、炉内ガス燃焼室１３に送給する空気の吸引量（または送出量）を必要量に制御するために、空気吸引パイプ２６の吸入空気吐出口２５に着脱自在な閉塞弁盤３４を載置し、空気吸引パイプ２６の外周には該閉塞弁盤３４の搭載自重で圧縮するコイルバネ３５を遊嵌し空気チャンバー１９の底板２０または架台３６に載置すると共に、空気吸引パイプ２６の吸入空気吐出口２５から過剰な高さに浮上する閉塞弁盤３４の飛行を制止する円板や環状板あるいはリボン状など任意な形状に成した閉塞弁盤飛行制止板３７を架設しかつ空気吸引パイプ２６を囲繞するコイルバネ３５を介して該空気吸引パイプ２６を取り囲む離隔位置に立設する２本または３本以上のガイド棒からなる枠体構造の弁盤昇降ガイドフレーム３８が、閉塞弁盤３４の昇降動作を阻害しない隙間を設けて底板２０または架台３６に固定されている。コイルバネ３５は、閉塞弁盤３４の浮上作用を助けまた降下時の衝撃を吸収するものである。また閉塞弁盤３４を外気と炉内ガス燃焼室１３の微小な差圧でも感度よく昇降させるため、空気チャンバー１９の隔離室Ａで局部的に淀む空気または炉内ガスの影響を避ける様に、気流空間を形成する気流ガイド板３９が弁盤昇降ガイドフレーム３８の外周上方側を囲繞する様にパイプ状に設けられている。また気流ガイド板３９の上端部は、閉塞弁盤飛行制止板３７に接近あるいは一体物に接着してもよい。さらに閉塞弁盤３４が同一垂直線上を昇降する様に、閉塞弁盤３４の空気吸引パイプ側にはコイルバネ３５の上端部側を遊嵌するコイルバネ遊嵌リング４０を設け、また空気チャンバー１９の底板２０または架台３６にはコイルバネ３５の下端部側を遊嵌するコイルバネ遊嵌リング４１を設けている。つまり、コイルバネ遊嵌リング４０は、昇降する閉塞弁盤３４が、降下したときにコイルバネ３５に片乗りする事なく定位置に搭載するためのガイド用リングであり、コイルバネ遊嵌リング４１は、閉塞弁盤３４が昇降する度に伸縮するコイルバネ３５の横移動させる事なく、定位置に安置させるものである。
上記の様に組立られた本発明における炉内ガス燃焼用空気送出量制御ノズル１７は、炉内ガス燃焼室１３が正圧の場合は連通する空気チャンバー１９も正圧になり、閉塞弁盤３４の上面に圧力が掛かってコイルバネ３５を圧縮し、該閉塞弁盤３４が空気吸引パイプ２６の上端面に吸着される様に載置し、空気の吸引を制止する。その反対に、炉内ガス燃焼室１３が負圧になった場合は空気チャンバー１９が負圧になり、閉塞弁盤３４が吸い上げられて浮上し、伸長するコイルバネ３５にも押し上げられながら空気吸引パイプ２６の吸入空気吐出口２５を開放し、その間に空気を吸引する。この様に閉塞弁盤３４が炉内ガス燃焼室１３の炉圧状況に追従する開閉動作を繰り返しながら、炉内ガス燃焼室１３に流入した炉内ガスを燃焼するに必要な量の空気を、空気チャンバー１９を介して、該炉内ガス燃焼室１３に送り込む機械的構造に設けられている。
尚、上記した炉内ガス燃焼用空気送出量制御ノズル１７において、閉塞弁盤３４の昇降動作を効果的に駆動させるにはガラス板、金属板、雲母板や合成樹脂などの軽量材料を使用するとよい。中でもガラス板は、炉内ガスに変質する事がなく、使用温度に変形する事がなく、平垣性にも優れているため、他の材料よりも適している。Furthermore, in the present invention, in order to control the suction amount (or delivery amount) of the air supplied to the in-furnace gas combustion chamber 13 to a necessary amount, a blocking valve that is detachably attached to the intake air discharge port 25 of the air suction pipe 26. A plate spring 34 is placed, and a coil spring 35 that is compressed by its own weight is mounted on the outer periphery of the air suction pipe 26 and is placed on the bottom plate 20 or the frame 36 of the air chamber 19. 26, an obstruction valve board flight stop plate 37 having an arbitrary shape such as a disc, an annular plate, or a ribbon is installed to stop the flight of the obstruction valve board 34 rising to an excessive height from the intake air discharge port 25 of the A valve plate lifting / lowering guide frame 38 having a frame structure composed of two or more guide rods standing at a separated position surrounding the air suction pipe 26 via a coil spring 35 surrounding the air suction pipe 26. It is fixed to the bottom plate 20 or frame 36 by a gap which does not inhibit the vertical movement of the closing valve plate 34. The coil spring 35 assists the floating action of the closing valve disc 34 and absorbs the impact when it is lowered. Moreover, in order to raise and lower the closing valve plate 34 with high sensitivity even with a minute differential pressure between the outside air and the in-furnace gas combustion chamber 13, in order to avoid the influence of air or in-furnace gas locally trapped in the isolation chamber A of the air chamber 19, An airflow guide plate 39 that forms an airflow space is provided in a pipe shape so as to surround the upper side of the outer periphery of the valve plate lifting guide frame 38. Further, the upper end portion of the airflow guide plate 39 may approach the obstruction valve board flight stop plate 37 or may be bonded to an integrated object. Further, a coil spring loose-fitting ring 40 for loosely fitting the upper end side of the coil spring 35 is provided on the air suction pipe side of the closing valve disc 34 so that the closing valve disc 34 moves up and down on the same vertical line, and the bottom plate of the air chamber 19 is provided. 20 or the gantry 36 is provided with a coil spring loose-fitting ring 41 for loosely fitting the lower end side of the coil spring 35. That is, the coil spring loose-fitting ring 40 is a guide ring for mounting the closed valve plate 34 that moves up and down in a fixed position without riding on the coil spring 35 when it descends, and the coil spring loose-fitting ring 41 is closed. The coil spring 35 that expands and contracts every time the valve plate 34 moves up and down is placed at a fixed position without being moved laterally.
In the in-furnace gas combustion air delivery amount control nozzle 17 according to the present invention assembled as described above, when the in-furnace gas combustion chamber 13 has a positive pressure, the air chamber 19 communicated with the in-furnace gas combustion chamber 13 also has a positive pressure. The coil spring 35 is compressed by applying pressure to the upper surface of the air valve, and the closed valve disc 34 is placed so as to be adsorbed to the upper end surface of the air suction pipe 26, thereby stopping air suction. On the other hand, when the gas combustion chamber 13 in the furnace becomes a negative pressure, the air chamber 19 becomes a negative pressure, the closing valve disc 34 is sucked up and floated, and the air suction pipe is pushed up by the extending coil spring 35. 26 intake air discharge ports 25 are opened, and air is sucked in the meantime. In this way, while the closing valve plate 34 repeats the opening and closing operation to follow the furnace pressure state of the in-furnace gas combustion chamber 13, the amount of air necessary for burning the in-furnace gas flowing into the in-furnace gas combustion chamber 13, It is provided in a mechanical structure that feeds into the in-furnace gas combustion chamber 13 through an air chamber 19.
In the above-described furnace gas combustion air delivery amount control nozzle 17, a light-weight material such as a glass plate, a metal plate, a mica plate, or a synthetic resin is used to effectively drive the lifting / lowering operation of the closing valve disc 34. Good. Among them, the glass plate is more suitable than other materials because it does not change into furnace gas, does not change to the operating temperature, and has excellent flat wall properties.

さらに本発明は、上記の炉内ガス燃焼用空気送出量制御ノズル１７を示す図２および図３において、４２は大口径の下向き外套カップで、必要に応じて使用されるものである。下向き外套カップ４２は、図２の吸入空気送出パイプ２９または図３の吸入空気送出カップ３１を内側上方に炉内ガスの噴留空間室Ｓを設ける様に被せる事によって、吸入空気送出パイプ２９の吸入空気流入口２８あるいは下方側開口の吸入空気送出カップ３１の吸入空気通気孔３０から噴出する炉内ガスの噴出速度を減速し、該炉内ガスに含まれる石炭などの浮遊粒子を噴出付近で落下除去し、閉塞弁盤３４の昇降付近の汚染化を防止して吸引空気の流通性を確保すると共に、良好なコークスの製造歩留りを向上する効果を有する。  Further, in the present invention, in FIG. 2 and FIG. 3 showing the above-mentioned furnace gas combustion air delivery control nozzle 17, 42 is a large-diameter downward mantle cup which is used as required. The downward facing outer cup 42 covers the intake air delivery pipe 29 by covering the intake air delivery pipe 29 of FIG. 2 or the intake air delivery cup 31 of FIG. The injection speed of the in-furnace gas ejected from the intake air inlet 28 or the intake air vent hole 30 of the intake air delivery cup 31 at the lower side opening is reduced, and floating particles such as coal contained in the in-furnace gas are near the ejection. It has the effect of dropping and removing, preventing contamination near the raising and lowering of the closing valve disc 34 to ensure the flowability of suction air, and improving the production yield of good coke.

さらに上記した炉内ガス燃焼用空気送出量制御ノズル１７は、図１で示す様に、吸入空気送出パイプ２９または吸入空気送出カップ３１と炉内ガス燃焼室１３に内設される空気噴出ノズルパイプ４３とを、噴出炉内ガス誘導パイプにも使用される送給空気誘導用接続パイプ４４や開閉バルブ４５を介して接続される。特に本発明においては、炉内ガス燃焼用空気送出量制御ノズル１７また接続パイプ間で目詰まりや損傷などを起こした場合に、分解補修作業や部品交換作業に都合のよいネジ継手法による組立工法が便利である。また開閉バルブ４５を使用する事は、急遽不必要になった空気を人為的に送出停止する場合に便利である。また空気噴出ノズルパイプ４３のノズル部分については、特に限定するものでなくパイプ孔、分散ノズル孔など任意な形状のノズル孔を使用してもよい。  Further, as shown in FIG. 1, the above-described furnace gas combustion air delivery amount control nozzle 17 includes an intake air delivery pipe 29 or an intake air delivery cup 31 and an air ejection nozzle pipe provided in the furnace gas combustion chamber 13. 43 is connected via a supply air induction connection pipe 44 and an open / close valve 45 which are also used for the gas induction pipe in the blowing furnace. In particular, in the present invention, when a clogging or damage is caused between the in-furnace gas combustion air delivery amount control nozzle 17 or the connecting pipe, an assembling method using a screw joint method that is convenient for disassembly and repair work or parts replacement work. Is convenient. The use of the open / close valve 45 is convenient when the air that has become unnecessary suddenly is stopped artificially. Further, the nozzle portion of the air ejection nozzle pipe 43 is not particularly limited, and a nozzle hole having an arbitrary shape such as a pipe hole or a dispersion nozzle hole may be used.

以上の様に構成された本発明のコークス炭化炉用昇温炉蓋は、前記した従来の炉蓋と同様に取扱われ、コークス製造作業が行われる。石炭粒子２の乾留初期においては、該石炭粒子２から発生した未燃焼ガスを含有した多量の炉内ガスがコークス炭化炉１の上方排気口（図示せず）から流れ出しまたその一部が炉内ガス燃焼室１３に流れ込み、コークス炭化炉１も炉内ガス燃焼室１３も正圧になる。この時の炉内ガス燃焼用空気送出量制御ノズル１７は、炉内ガス燃焼室１３の正圧に連動し、空気チャンバー１９の閉塞弁盤３４が空気吸引パイプ２６の吸入空気吐出口２５を押圧する様に降下し、空気の吸引を遮断する。乾留時間の経過に炉内ガスの発生量が徐々に減少し、炉内ガス燃焼室１３は正負圧境界域を交互に上下に繰り返しながら乾留末期まで続く。この現象が起因する理由は現時点では明らかにする事ができないが、本発明者らの推察によれば、石炭粒子２から発生する炉内ガス発生量の減少とコークス炭化炉１と炉内ガス燃焼室１３との間で起こるガス流通経路の変化によるものと考える。正負圧境界域で変化する炉内ガス燃焼室１３が負圧化する毎に空気チャンバー１９も負圧化し、閉塞弁盤３４が空気吸引パイプ２６の吸入空気吐出口２５から吸い上げられ浮上し、浮上時間に見合った量の空気すなわち炉内ガス燃焼室１３に流れ込んだ炉内ガスを燃焼させるに必要な量の空気を送り込み、未燃焼ガスを燃焼させる。燃焼した際の熱圧で炉内ガス燃焼室１３は正圧になり、閉塞弁盤３４は、空気吸引パイプ２６の吸入空気吐出口２５を塞ぎ、空気の吸引を絶つ。この燃焼圧の影響を受けて空気チャンバー１９に逆流する炉内ガスは、ガス昇降流通ガイド板２３あるいは必要に応じて設けられた下向き外套カップ４２の流通抵抗による減速効果で、該炉内ガスに含有される石炭などの浮遊粒子の一部が吸入空気送出カップ３１内に落下しまた空気チャンバー１９の隔離室Ｂで落下し堆積する。従って、空気チャンバー１９をガス昇降流通ガイド板２３で隔離された隔離室Ａは、炉内ガスに含まれる浮遊粒子で汚染される事がなく、炉内ガス燃焼室１３に流れ込んだ炉内ガスを燃焼させるに必要な量の空気を長期間安定して送給する事ができる。  The temperature rising furnace lid for the coke carbonization furnace of the present invention configured as described above is handled in the same manner as the conventional furnace lid described above, and coke production work is performed. At the initial stage of dry distillation of the coal particles 2, a large amount of in-furnace gas containing unburned gas generated from the coal particles 2 flows out from an upper exhaust port (not shown) of the coke carbonization furnace 1, and part of the in-furnace gas is in the furnace It flows into the gas combustion chamber 13, and the coke carbonization furnace 1 and the in-furnace gas combustion chamber 13 become positive pressure. At this time, the air discharge amount control nozzle 17 for in-furnace gas combustion interlocks with the positive pressure in the in-furnace gas combustion chamber 13, and the closing valve disc 34 of the air chamber 19 presses the intake air discharge port 25 of the air suction pipe 26. Then, it will descend and shut off air suction. The amount of in-furnace gas generated gradually decreases as the dry distillation time elapses, and the in-furnace gas combustion chamber 13 continues to the end of the dry distillation while alternately repeating the positive and negative pressure boundary regions up and down. The reason for this phenomenon cannot be clarified at the present time. However, according to the inventor's inference, the decrease in the amount of gas generated in the furnace from the coal particles 2 and the coke carbonization furnace 1 and the gas combustion in the furnace This is considered to be due to a change in the gas flow path that occurs between the chamber 13 and the chamber 13. Each time the in-furnace gas combustion chamber 13 that changes in the positive / negative pressure boundary region becomes negative pressure, the air chamber 19 also becomes negative pressure, and the closing valve disc 34 is sucked up from the intake air discharge port 25 of the air suction pipe 26 and floats. An amount of air commensurate with time, that is, an amount of air necessary for burning the in-furnace gas flowing into the in-furnace gas combustion chamber 13 is fed to burn unburned gas. The in-furnace gas combustion chamber 13 becomes a positive pressure by the heat pressure at the time of combustion, and the closing valve disc 34 closes the intake air discharge port 25 of the air suction pipe 26 and stops the suction of air. The in-furnace gas that flows back to the air chamber 19 under the influence of the combustion pressure is reduced to the in-furnace gas by the effect of deceleration due to the flow resistance of the gas elevating flow guide plate 23 or the downward outer cup 42 provided as necessary. Part of the suspended particles such as coal contained falls into the intake air delivery cup 31 and falls and accumulates in the isolation chamber B of the air chamber 19. Therefore, the isolation chamber A in which the air chamber 19 is isolated by the gas up-and-down flow guide plate 23 is not contaminated by the suspended particles contained in the in-furnace gas, and the in-furnace gas flowing into the in-furnace gas combustion chamber 13 is removed. The amount of air required for combustion can be stably delivered for a long period of time.

さらに本発明は、コークス乾留中に何らかの原因で、炉内ガス燃焼室１３の炉内ガスを燃焼させるに必要な量以上の空気を吸い込んで局部的に小爆発を起こす危険性を察したときは、開閉バルブ４４を閉める事によって、空気の供給を遮断し、未然に小爆発を防止する事ができる。  Furthermore, when the present invention observes the risk of causing a small explosion locally by sucking in air more than the amount necessary for burning the furnace gas in the furnace gas combustion chamber 13 for some reason during coke dry distillation. By closing the opening / closing valve 44, the supply of air can be cut off and a small explosion can be prevented.

世界的にコークス供給量の不足さらには一刻も早い環境改善対策が叫ばれる中で、本発明のコークス炭化炉蓋は、時代の要求に叶った装置として国内外が益々使用される可能性が極めて高い。  With the worldwide shortage of coke supply and the prompt improvement of the environment as soon as possible, the coke carbonization furnace lid of the present invention is extremely likely to be used more and more in Japan and overseas as a device that meets the needs of the times. high.
