Description

本発明は、コークス炉から発生する粉塵ガスの集塵装置に関するものである。  The present invention relates to a dust collector for dust gas generated from a coke oven.

技術背景Technical background

一般に、コークス炉の集塵については、従来から集塵方法および集塵装置が提案されている。コークス炉窯出し作業時にコークサイドから飛散する含塵ガスの捕集には、コークガイド車に設けた集塵フードで捕集して、固定ダクトを介して地上に設置したバッグフィルタなどの集塵装置に含塵ガスを吸引する方式が採用されている。  In general, a dust collection method and a dust collection apparatus have been proposed for dust collection in a coke oven. Dust collection such as bag filters installed on the ground through a fixed duct is collected with a dust collection hood provided on the coke guide car to collect dust-containing gas that scatters from the coke side during work in the coke oven kiln. A system for sucking dust-containing gas is adopted in the apparatus.

また、コークス炉の炭化室に石炭を装入する際、装入口から大気に噴出するガスを装炭車に設けられた集塵フードで捕集して、固定ダクトを介して地上に設置した湿式集塵機などの集塵装置に含塵ガスを吸引する方式が採用されている。  In addition, when coal is charged into the coking oven carbonization chamber, the wet dust collector installed on the ground via a fixed duct that collects the gas ejected from the inlet into the atmosphere with a dust collection hood provided in the coal loading vehicle. A method of sucking dust-containing gas into a dust collector such as is adopted.

発明が解決しょうとする課題Problems to be solved by the invention

従来コークス炉において、コークガイド車および装炭車の各集塵系に用いられている地上設置の固定ダクトの大きさは、所定の集塵風量パターンに沿って決められており、各集塵系の最大ピーク値に合わせて設定されている。一方過剰設定による設備コストおよび運転コストの増大を防ぐため、必然的にガイドおよび装炭系固定ダクトの大きさおよび長さは制約されたものとなっている。  In the conventional coke oven, the size of the fixed duct installed on the ground used for each dust collection system of the coke guide car and the coal truck is determined according to a predetermined dust collection air flow pattern. It is set according to the maximum peak value. On the other hand, in order to prevent an increase in equipment cost and operation cost due to excessive setting, the size and length of the guide and the coal-equipped fixed duct are inevitably restricted.

このため最近の生産の増産要求に見合う集塵風量パターンに対しては、風速が増すため、固定ダクトの内壁の摩耗による破損が懸念される事とダクト内の過剰な圧力損失による運転コストの増大といった問題があった。  For this reason, the wind speed increases for the dust collection air flow pattern that meets the demand for increased production in recent production, so there is concern about damage due to wear on the inner wall of the fixed duct and an increase in operating cost due to excessive pressure loss in the duct. There was a problem.

本発明は、上記問題点を解消するために成されたもので、既設の固定ダクトを使用して、生産の増産要求に見合う集塵風量の増加に対しても、ガイドまたは装炭系固定ダクトが損傷することなくまた集塵能力も低下させることなく、さらには設備費を低減できるようにした集塵装置を提供することを目的とする。  The present invention has been made to solve the above-mentioned problems, and the guide or the coal-fixed duct is used for the increase in the amount of dust collected to meet the production increase demand using the existing fixed duct. An object of the present invention is to provide a dust collecting device that can reduce the equipment cost without damaging the dust and without reducing the dust collecting ability.

発明が解決するための手段Means for Solving the Invention

本発明の第１の発明は、コークガイド車に搭載した集塵フードと、この集塵フードに取付けた伸縮自在なコネクタと、前記コークガイド車の走行方向と並行して地上側に設置したガイド系固定ダクトと、ガイド系固定ダクトに連通したバッグフィルタからなり、コークス炉から押出された赤熱コークスをコークガイド車を介して消火車に積載する際に発生する粉塵を処理するようにした集塵装置に於いて、ガイド系固定ダクトの両端に、バッグフィルタに連通し且つ風量調整ダンパーを有するガイド系ループダクトを接続したことを特徴とするものである。  A first aspect of the present invention is a dust collection hood mounted on a cork guide car, a telescopic connector attached to the dust collection hood, and a guide installed on the ground side in parallel with the traveling direction of the coke guide car. A dust collection system consisting of a system fixed duct and a bag filter communicating with the guide system fixed duct, which treats dust generated when red hot coke extruded from a coke oven is loaded onto a fire extinguisher via a coke guide car In the apparatus, a guide loop duct that communicates with the bag filter and has an air volume adjusting damper is connected to both ends of the guide system fixing duct.

本発明の第２の発明は、装炭車に取付けた集塵フードと、前記集塵フードに取付けた伸縮自在なコネクタと、前記装炭車の走行方向と並行して炉頂上部に設置した装炭系固定ダクトと、この装炭系固定ダクトに連通した湿式集塵機からなり、石炭装入時に石炭装入口から噴出するガスおよび粉塵を処理するようにした集塵装置に於いて、装炭系固定ダクトの両端に、湿式集塵機に連通し且つ風量調整ダンパーを有する装炭系ループダクトを接続したことを特徴とするものである。  The second invention of the present invention is a dust collecting hood attached to a coal-equipped vehicle, a telescopic connector attached to the dust collecting hood, and a coal-installing device installed at the top of the furnace in parallel with the running direction of the coal-equipped vehicle. In a dust collector comprising a fixed duct and a wet dust collector communicating with the coal-equipped fixed duct and treating gas and dust ejected from the coal inlet at the time of coal charging, the coal-equipped fixed duct A charcoal-based loop duct that communicates with a wet dust collector and has an air volume adjusting damper is connected to both ends of the steel.

また、上記問題解決手段による作用は次の通りである。すなわち、ガイドまたは装炭系固定ダクトの両端に、バッグフィルタあるいは湿式集塵機に連通し且つ風量調整ダンパーを有するガイドまたは装炭系ループダクトをそれぞれ接続しているので、集塵風量パターンが従来にない多風量に変化しても各ループダクトの風量調整ダンパーを調整することにより、ガイドまたは装炭系固定ダクト内壁の損傷を起こすことなく、さらにダクト内の圧力損失も高めることなくスムーズな集塵処理を可能にしたものである。  The operation of the above problem solving means is as follows. That is, a guide or a charcoal loop duct, which is connected to a bag filter or a wet dust collector and has an air flow adjustment damper, is connected to both ends of the guide or the charcoal system fixed duct, respectively. Even if it changes to a large air volume, by adjusting the air volume adjustment damper of each loop duct, smooth dust collection without causing damage to the inner wall of the guide or the coal-mounted fixed duct and without increasing the pressure loss in the duct Is made possible.

発明の効果The invention's effect

上述したように、本発明のコークス炉集塵装置は次のような効果が得られる。
（１）既設のガイドまたは装炭固定ダクトにループダクトを接続するだけといった簡単な構造で、既設のガイドまたは装炭系固定ダクトを撤去して新たな固定ダクトに取り替えることなく、風量の増強に対応できるようにしたもので、大幅な設備費の低減につながるものである。
（２）風量の増強に対してもガイドまたは装炭系固定ダクト内壁の損傷を起こすことがない。
（３）従来にない多風量の変化に対しても集塵効率を向上させるといった効果を奏するものである。
（４）ダクト内の圧力損失を高めることがないため、運転コストの削減効果を達成できるものである。As described above, the coke oven dust collecting apparatus of the present invention has the following effects.
(1) With a simple structure such as simply connecting a loop duct to an existing guide or coal-fixing duct, it is possible to increase the air flow without removing the existing guide or coal-fixing duct and replacing it with a new one. It is designed to be able to cope with it, which leads to a significant reduction in equipment costs.
(2) Even if the air volume is increased, the inner wall of the guide or the coal-fixed duct will not be damaged.
(3) There is an effect that dust collection efficiency is improved even when there is a change in the amount of air that is not present.
(4) Since the pressure loss in the duct is not increased, the effect of reducing the operating cost can be achieved.
