Description
本発明は、コークスの重量を測定するための方法、及びコークス消火車に関する。 The present invention relates to a method for measuring the weight of coke and a coke fire extinguisher.
石炭のコーキングに際しては、コークス炉の個々の炉室の充填工程が一時的に注入操作で行われる。これは石炭充填車により、コークス炉バッテリーの炉室の炉カバー上で行われる。石炭充填車は、投入石炭を石炭塔から受入れ、これをコークス炉バッテリーの炉室に輸送する。投入石炭は、そこで充填穴によって炉室へ充填される。形成される円錐形の堆積物は平面棒で平らにされる。石炭は、二面から加熱された炉室への充填後に、炉室壁から炉室中心まで段階的にコークスに変換される。この場合、炉室にはコークスケーキが形成され、ここで炉室からのコークスケーキの排出のために、押出車の押出棒が炉室を横断し、コークスをコークスケーキ誘導車またはコークス移行車を介して消火車へ押し出す。赤く燃えるコークスは、消火車で消火塔の下へ移動され、そこで、空気に触れて燃焼しないように水で急冷される。その間に、空になったコークス炉は、直ちに再び新しい石炭で充填される。急冷されたコークスは消火車からコークス傾斜台へスライドし、ここで脱水され、次いでコンベヤーベルトを介してコークスろ過器へ達する。コンベヤーベルトは、消火されたコークスの重量決定のために形成されているベルト秤を有する。消火されたコークスの測定された重量は、コーキング工程中に獲得されうる収量の計算のために役立つと同時に、コークス炉におけるコークスの製造のために見積もる必要があるコストの計算の前提である。 During the coking of coal, the filling process of each furnace chamber of the coke oven is temporarily performed by an injection operation. This is done by a coal-filled vehicle on the furnace cover of the coke oven battery furnace chamber. The coal-filled vehicle receives the input coal from the coal tower and transports it to the furnace chamber of the coke oven battery. The input coal is then filled into the furnace chamber through a filling hole. The conical deposit formed is flattened with a flat bar. Coal is converted into coke stepwise from the furnace chamber wall to the center of the furnace chamber after filling into the furnace chamber heated from two sides. In this case, a coke cake is formed in the furnace chamber, and in order to discharge the coke cake from the furnace chamber, the extrusion rod of the extrusion car crosses the furnace chamber, and the coke is passed through the coke cake induction car or the coke transition car. To the fire extinguisher. The coke that burns red is moved down the fire tower with a fire extinguisher, where it is quenched with water to avoid contact with the air and burning. Meanwhile, the empty coke oven is immediately refilled with fresh coal. The quenched coke slides from the fire extinguisher to the coke ramp, where it is dewatered and then reaches the coke filter via the conveyor belt. The conveyor belt has a belt scale formed for determining the weight of the fired coke. The measured weight of the extinguished coke is useful for calculating the yield that can be obtained during the coking process, and at the same time is the premise for calculating the cost that needs to be estimated for the production of coke in the coke oven.
コークスろ過器へのコークスの輸送工程中におけるベルト秤によるコークス重量を測定するための周知の方法における不利点は、コークスの総重量が消火された状態で計測され、ここで消火水の一部がいっしょに計測されてしまい、これがコークスの脱水後にもコークス中に存在し、測定結果の歪曲をもたらしうることである。さらに、不利点は、以前のコーキング工程からのベルト秤上に存在するコークスの残りの重量が、重量決定に影響を及ぼすことである。したがって、コーキング工程の収量を高い精度で示しうることは不可能である。これは不確実性としてコスト計算に対してマイナスに作用する。 A disadvantage of the known method for measuring the coke weight with a belt balance during the process of transporting the coke to the coke filter is that the total weight of the coke is measured with the fire extinguished, where a part of the fire water is It is measured together, and this is present in the coke even after dewatering of the coke, which can cause distortion of the measurement results. Furthermore, the disadvantage is that the remaining weight of coke present on the belt balance from the previous coking process affects the weight determination. Therefore, it is impossible to show the yield of the coking process with high accuracy. This has a negative effect on cost calculation as an uncertainty.
本発明の課題は、コークスの重量を測定するための方法及びコークスの重量の正確な測定が可能であるコークス消火車を提供することである。 An object of the present invention is to provide a method for measuring the weight of coke and a coke fire extinguisher capable of accurately measuring the weight of coke.
上記の課題は、コークスの重量を測定するための方法における第１の案において、測定がコークスの消火されていない状態で、好ましくは、コークス炉の炉室からのコークスの押し出し直後または押し出し中に行われることによって実質的に解決されている。したがって、本発明の基本的な考えは、コークスが消火水で冷却される前に、言い換えると最終的に押し出しの直後にコークスの重量の測定を実施することにある。消火工程前の重量測定は、コークス製造の収量の算出に際してコークス室における消火水の一部によって結果の歪曲をもたらさないことを保証する。それによって、コークス炉におけるコークスの製造と関係にあるコストの計算を、これまで可能であったよりも高い精度で実施することが可能である。 The above problem is that in the first proposal in the method for measuring the weight of coke, the measurement is performed in a state where the coke is not extinguished, preferably immediately after or during extrusion of coke from the furnace chamber of the coke oven. It is substantially solved by being done. Therefore, the basic idea of the present invention is to carry out a measurement of the weight of the coke before it is cooled with fire-extinguishing water, in other words, immediately after extrusion. The gravimetric measurement prior to the fire fighting process ensures that in calculating the yield of coke production, some of the fire water in the coke chamber does not result in distortion. Thereby, it is possible to carry out the calculation of the costs associated with the production of coke in a coke oven with a higher accuracy than was previously possible.
コーキング工程の収量を高い精度で示しうるために、各々の炉室のコークスの重量決定が意図されうるため、コークス炉バッテリーの個々の炉室のコーキング工程の収量について述べることが可能である。その他は、炉室の各々のコーキング工程からのコークスが重量に関して測定されることが意図されうる。 Since the coke weight of each furnace chamber can be intended to be able to show the coking process yield with high accuracy, it is possible to describe the coke process yield of the individual furnace chambers of the coke oven battery. Otherwise, it can be intended that the coke from each coking step in the furnace chamber is measured in terms of weight.
本発明による方法の１つの実施形態においては、重量の測定は、コークス消火車のそばまたはその中で行われることが意図されている。好ましくは、本発明による方法の別の実施形態においては、コークスは消火されていない状態でも計量されるが、基本的には、コークスの重量をコークス消火車のそばまたはその中で、好ましくは、消火工程の直後に測定することも可能である。このようにして、消火工程直後に算出されうる消火水の重量及び消火されたコークスの重量から、消火されていないコークスの重量が算出されうる。 In one embodiment of the method according to the invention, the weight measurement is intended to be performed by or in a coke fire truck. Preferably, in another embodiment of the method according to the invention, the coke is weighed even in an unfired state, but basically the weight of the coke is preferably near or in the coke fire truck. It is also possible to measure immediately after the fire extinguishing process. In this way, the weight of the coke that has not been extinguished can be calculated from the weight of the fire extinguishing water that can be calculated immediately after the fire extinguishing step and the weight of the fire extinguished coke.
本発明による方法の別の実施形態においては、コークスがコークス消火車に積載され、かつコークス消火車の重量が固定した貨車秤で測定されることが意図されている。コークス消火車の重量測定のためには、貨車秤は、適切な測定装置と結合されている貨車部を有しうる。測定装置は、貨車部の下部に配置されている揺れ台室を有しうる。好ましくは、貨車部は、少なくともコークス消火車の長さに対応する長さを有する。本発明の方法によれば、コークス消火車の重量測定は消火塔において、またはコーク消火車の消火塔への挿入前に行われることが意図されうる。コークス消火車の重量測定は、好ましくは、コークス消火車が貨車秤へ移動するとすぐに、これの停止中に行われる。 In another embodiment of the method according to the invention, it is intended that coke is loaded on a coke fire truck and the weight of the coke fire truck is measured on a fixed wagon scale. For the weight measurement of a coke fire extinguisher, the wagon scale can have a wagon part coupled with a suitable measuring device. The measuring device may have a shaker room arranged at the lower part of the freight car part. Preferably, the freight car portion has a length corresponding to at least the length of the coke fire extinguisher. According to the method of the present invention, it may be intended that the weight measurement of the coke fire extinguisher takes place in the fire extinguisher or before insertion into the fire extinguisher of the coke fire extinguisher. The weight measurement of the coke fire extinguisher is preferably carried out during its stop as soon as the coke fire extinguisher has moved to the wagon scale.
本発明の装置によれば、コークス消火車は、コークス消火車に存在するコークスの重量の測定のために形成されているコークス消火車のそばまたはその中に測定装置を有する。測定装置は、測定評価手段として、少なくとも１つの揺れ台室及び／または少なくとも１つの膨張測定テープを有しうる。コークス消火車のそばまたはその中の重量測定はさらに、重量測定の実施が少ない構成上のコスト及び高い確実性とともに可能である利点を有する。測定評価手段は、コークス消火車の車軸支持材に備えられ、自重測定に際して基礎構造及びその上に配置された前記コークス消火車のコークス容器の重量を測定する。基本的にはもちろん、測定評価手段は、コークス消火車の基礎構造とその上に配置されたコークス容器との間に備えられ、自重測定時にコークス容器の重量を測定する。最初に挙げたケースでは、消火車の総重量が把握される。それに対して、最後に挙げたケースでは、コークス容器の重量のみが測定される。 According to the device of the present invention, the coke fire extinguisher has a measuring device beside or in the coke fire extinguisher configured for measuring the weight of coke present in the coke fire extinguisher. The measuring device may have at least one shaking chamber and / or at least one expansion measuring tape as measurement evaluation means. Weighing by or in a coke fire extinguisher further has the advantage that it is possible to perform weighing with low construction costs and high certainty. The measurement and evaluation means is provided on the axle support material of the coke fire extinguisher, and measures the weight of the basic structure and the coke container of the coke fire extinguisher arranged on the axle when measuring its own weight. Of course, the measurement evaluation means is provided between the basic structure of the coke fire extinguisher and the coke container disposed thereon, and measures the weight of the coke container when measuring its own weight. In the first case, the total weight of the fire engine is known. In contrast, in the last case, only the weight of the coke container is measured.
コークスの重量をできるだけ歪曲せずコーキング工程の終了後に測定しうるために、重量の測定を、コークスのコークス消火車への挿入直後に実施する本発明の２つの別の実施形態が可能である。これについて、消火工程が始まる前にコークスの重量が測定されることが重要である。 Since the coke weight can be measured after the coking process without distortion as much as possible, two alternative embodiments of the invention are possible in which the weight measurement is performed immediately after insertion of the coke into the coke fire engine. In this regard, it is important that the weight of the coke is measured before the fire fighting process begins.
正味重量の補正のためにコークス消火車へのコークスの挿入前に、重量測定が空のコークス消火車のそばまたはその中で実施されうる。コークス消火車の自重測定は、以前の消火工程のコークス消火車上に残存したコークスの残りによるコークスの重量測定に際しての測定結果の歪曲を排除するために役立つ。好ましくは、各々の測定工程前にターリングが意図され、ここで本発明は基本的にもちろん、コークス容器の自重測定のみが行われることも可能である。 Before the coke is inserted into the coke fire extinguisher for correction of the net weight, a weight measurement can be performed beside or in the empty coke fire extinguisher. The self-weight measurement of the coke fire extinguisher is useful for eliminating distortion of the measurement result when measuring the weight of the coke due to the remaining coke remaining on the coke fire extinguisher in the previous fire extinguishing process. Preferably, taring is intended before each measuring step, where the invention is of course basically possible only for measuring the own weight of the coke vessel.
正味重量の補正は、コークス消火車の停止に際して、かつコークス消火車のコークス移行位置における配置に際して、コークス消火車の移動に起因しうる障害を排除するために行われうる。炉室からのコークスの完全な押し出し後、または炉室から消火塔へのコークス消火車の途中の任意の位置で、その後に自動的に測定が実施され、ここで測定信号が、コークスが完全に炉室から押し出される時点を示しうる。この信号に基づき、重量測定がコークス消火車の停止に際して完全重量測定として、特にコークス移行位置において行われうる。次いで、コークス消火車に存在するコークスの重量は、ターリングに際して測定された自重及び測定された完全重量から自動的に算出されうる。最後に挙げた特徴はコークス消火車の重量測定に関連するが、基本的にはもちろん、コークス容器の重量が正味重量の補正に際して空の状態で、かつその後に充填された状態で算出されることも可能である。移行車における消火車の移行位置を検出しうるために、位置検出器が備えられうる。 The correction of the net weight can be performed to eliminate obstacles that may be caused by the movement of the coke fire extinguisher when the coke fire extinguisher is stopped and when the coke fire extinguisher is disposed at the coke transition position. After complete extrusion of coke from the furnace chamber, or anywhere in the middle of the coke fire extinguisher from the furnace chamber to the fire extinguisher, a subsequent automatic measurement is performed, where the measurement signal indicates that the coke is completely It can indicate when it is pushed out of the furnace chamber. Based on this signal, the weight measurement can be performed as a complete weight measurement when the coke fire engine is stopped, especially at the coke transfer position. The weight of the coke present in the coke fire extinguisher can then be automatically calculated from the own weight measured during the turing and the measured complete weight. The last feature is related to the weight measurement of the coke fire extinguisher, but of course, the weight of the coke container is of course calculated when the net weight is corrected and filled afterwards. Is also possible. In order to be able to detect the transition position of the fire extinguisher in the transition vehicle, a position detector may be provided.
算出されたコークスの重量は、演算装置に供給され、その後の充填工程の制御による適切な評価後に炉室が適切に考慮されうる。好ましくは、この場合のコークスの重量測定は、炉室からのコークスの押し出し直後に行われ、すでに次の充填工程において重量測定からの結果を適切に考慮することが可能である。 The calculated coke weight is supplied to the arithmetic unit, and the furnace chamber can be properly taken into account after appropriate evaluation by controlling the subsequent filling process. Preferably, the weight measurement of the coke in this case is performed immediately after extrusion of the coke from the furnace chamber, and the results from the weight measurement can be appropriately taken into account in the next filling step.
本発明の装置によれば、このケースでの測定装置は演算装置と結合され、演算装置は測定工程の制御のため、かつ測定結果の評価のため、及び／または測定結果及び／または評価結果の記憶のために設けられている。演算装置は、適切な方法で炉室の充填工程の制御のためにも形成されうる。さらに、算出された重量を演算装置からデータネットワーク、好ましくは、インターネット、またはフィールドバスシステムを介して受信機に伝達し、もしくは、データネットワークを介して記憶された測定結果及び／または評価結果へのアクセスを可能にすることが可能である。 According to the device of the invention, the measuring device in this case is combined with a computing device, the computing device for controlling the measurement process and for evaluating the measurement result and / or for the measurement result and / or the evaluation result. Provided for memory. The computing device can also be formed for controlling the filling process of the furnace chamber in a suitable manner. Further, the calculated weight is transmitted from the arithmetic unit to the receiver via a data network, preferably the Internet or a fieldbus system, or stored in the measurement result and / or evaluation result stored via the data network. It is possible to allow access.
