Description
【発明の詳細な説明】 ［産業上の利用分野１ 本発明は焼却灰溶融炉のスラグ排出口に関する。[Detailed description of the invention] [Industrial application field 1 The present invention relates to a slag discharge port of an incinerated ash melting furnace.
［従来の技術］
都市ゴミは従来、埋立により処分されていたが埋立の用
地確保が難しくなり、−旦焼却してから、焼却灰を処分
するようになってきた。しかし、ごみの焼却によっても
約１０％の焼却灰が発生し、灰の埋立処分用の用地すら
逼迫するようになってきた。さらに灰の埋立処分におい
て微粉状灰の飛敗、重金属類の浸出、未燃焼物による悪
臭など環境上の問題も発生している。[Prior Art] Conventionally, municipal waste has been disposed of in landfills, but as it has become difficult to secure land for landfills, it has become necessary to first incinerate the waste and then dispose of the incinerated ash. However, approximately 10% of the waste is incinerated as ash, and even land for ash landfill disposal is becoming scarce. Furthermore, when disposing of ash in landfills, environmental problems such as pulverized ash, leaching of heavy metals, and bad odors from unburned materials occur.
そこでごみ焼却灰を溶融して処理し、埋立に際して減容
を図ると同時に粉末の溶融重金属浸出の防止、未燃物の
分解を行って環境上の保全を一挙に達成する方法がとら
れている。その際プラズマ炉を用いて行うことが多い（
特願昭６３−１．０１３６０）。Therefore, methods have been adopted to melt and process waste incineration ash to reduce its volume before landfilling, while at the same time preventing the leaching of molten heavy metals from the powder and decomposing unburned materials to achieve environmental conservation all at once. . This is often done using a plasma furnace (
Patent application 1986-1.01360).
このような焼却灰溶融炉では、溶融スラグ排出孔周辺の
耐火物損傷が激しく、操業およびメンテナンス上の隘路
となっており、コストアップの要因となっていた。In such an incinerated ash melting furnace, the refractories around the molten slag discharge hole are severely damaged, creating a bottleneck in operation and maintenance, and causing an increase in costs.
［発明が解決しようとする課題］
本発明は焼却灰溶融炉の溶融スラグの排出口のメンテナ
ンスを容易にし操業の円滑化とコストダウンを図ること
を目的とする。[Problems to be Solved by the Invention] An object of the present invention is to facilitate maintenance of a molten slag discharge port of an incinerated ash melting furnace, thereby facilitating operation and reducing costs.
〔課題を解決するための手段］
本発明は、廃棄物焼却灰溶融装置において、溶融スラグ

気露出液面の側壁に着脱交換可能な堰を設けたことを特
徴とする焼却灰溶融炉のスラグ排出口である。[Means for Solving the Problems] The present invention, in a waste incineration ash melting device, exposes a part of the liquid surface of molten slag to the atmosphere via a hidden weir, and attaches and detaches a part to the side wall of the liquid surface exposed to the atmosphere. This is a slag discharge port of an incinerated ash melting furnace characterized by being equipped with a replaceable weir.
〔作用１
溶融スラグは隠れ堰を通って、連通管の原理によって、
炉殻の外に出て、液面が露出するようにし、この露出部
にオーバーフロー堰を設ける。[Action 1: The molten slag passes through the hidden weir, and according to the principle of a communicating pipe,
The liquid level is exposed outside the furnace shell, and an overflow weir is installed in this exposed area.
焼却灰の供給に従って、溶融したスラブはオーバーフロ
ー堰を溢流する。このオーバーフロー堰を鋳鉄製の金物
で覆い、これが侵食により減耗したら随時交換する。交
換時には第３図に示すように炉を若干矢印方向に傾転さ
せれば、操業を中断することなく交換作用を行うことが
できる。Following the incineration ash supply, the molten slab overflows the overflow weir. This overflow weir is covered with cast iron hardware, which is replaced whenever it becomes worn out due to erosion. At the time of replacement, by slightly tilting the furnace in the direction of the arrow as shown in FIG. 3, the replacement can be performed without interrupting operation.
〔実施例］

出部７にはオーバーフロー堰８が設けられ本発明のスラ
グ排出口となっている。The molten slag 4 passes through the hidden weir 5 and flows out to the atmosphere exposed part 7 according to the principle of a communicating pipe, forming a liquid level 6. This atmospheric exposure part 7 is provided with an overflow weir 8 and serves as a slag discharge port of the present invention.
