【０００１】
【発明の属する技術分野】
本発明は、廃棄物溶融炉で廃棄物を溶融し、生成した溶融スラグを水砕化する設備に関するものである。
【０００２】
【従来の技術】
一般廃棄物あるいは産業廃棄物などの廃棄物の溶融処理方法は、廃棄物をコークス、石灰石等の副原料とともに廃棄物溶融炉に装入し、廃棄物を溶融スラグとして取り出し、溶融スラグを水砕処理するもので、水砕処理では水砕水を循環させている。図２は、従来の廃棄物溶融処理における水砕水循環設備の概念図である。この図に示すように、溶融炉から約１回／時間の割合で間歇出滓した溶融スラグを水砕ピット１に流し込み、水砕水で急冷して水砕化し、水砕スラグは沈澱する。沈澱した水砕スラグは水砕ピット１から取り出される。
【０００３】
水砕ピット１には、水砕水が循環供給されており、水砕ピット１をオーバフローした水砕水排水は、水砕水貯留槽２に送られるが、水砕ピット１をオーバフローした水砕水排水には発泡等により軽くなった、沈澱しないＳｉＯ2 、Ａｌ2 Ｏ3 、ＣａＯのスラグ成分等の固形物が含まれる。固形物を含んだ状態で水砕水を循環させると、ポンプの故障、配管の詰まりのもとになるので、固形物を水砕水排水から除去するために、水砕水濾過器３を介して水砕水貯留槽２に供給される。水砕水貯留槽２に一旦供給された水砕水排水は、約６０℃の水温を有するので冷却するために、冷却塔循環ポンプ６で水砕水冷却塔４に送られ、約５０℃に冷却され、再度、水砕水貯留槽２に供給され、冷却された水砕水は、水砕水循環ポンプ５で水砕ピット１に送られるような構造になっている。
【０００４】
【発明が解決しようとする課題】
上述した水砕水循環設備において、水砕ピットから水砕水貯留槽までの配管、水砕水貯留槽から水砕水冷却塔までの配管、およびその戻り配管が長いため、それらのイニシアルコストが高く、また、それら配管内にスラジが詰まるのを防止するために常時メンテナンスが必要となる。また、水砕ピット内には沈澱しない固形物が、オーバフローした水砕水排水中に含まれており、配管内の詰まりの原因となるので、これらを除去するための濾過器、さらには、オーバフローした水砕水を一旦貯留するため水砕水貯留槽が必要となる。水砕水貯留槽にも濾過器を通過した固形物が沈澱するため、当然、これらを除去するための設備、すなわち、スクレーパやポンプ等が必要となる。
【０００５】
また、水砕水冷却塔は、屋外設置となるので騒音防止や建屋壁部への飛散水による汚れ、防錆塔の配慮が必要となる。以上、従来技術にあっては、設備的にイニシアルコストおよびそのメンテナンス費用が大きく、また、関連設備が多いため設備の据付スペースが広範囲となると共に、その運転のためのランニングコストも多大となるという問題がある。
【０００６】
【課題を解決するための手段】
上述したような問題を解消するために、発明者らは鋭意開発を進めた結果、スラグを水砕処理する能力を全て水砕ピット内に集約し、非常にコンパクトな設備構成とし、関連装置やそのための配管を削減し、設備据付エリアを水砕ピット内のみにした廃棄物溶融処理におけるスラグ水砕処理設備を提供する。その発明の要旨とするところは、
（１）廃棄物をシャフト炉式熱分解溶融炉で熱分解処理し、排出された溶融物を水砕ピットで水砕処理する設備において、前記水砕ピット内に、スラグ噴射用水中ポンプとピット内の水砕水の冷却器を内設したことを特徴とする廃棄物溶融処理におけるスラグ水砕処理設備。
（２）前記（１）に記載の水砕処理設備において、水砕ピット内の冷却器近傍に流速発生用の流速発生装置を内設したことを特徴とする廃棄物溶融処理におけるスラグ水砕処理設備にある。
【０００７】
【発明の実施の形態】
以下、本発明について図面に従って詳細に説明する。
図１は、本発明に係る廃棄物溶融処理におけるスラグ水砕処理設備の概念図である。この図に示すように、水砕ピット１内で、予め水砕水を貯留しておき、この水砕ピット１には、溶融炉から落下してくる溶融スラグを冷却、水砕化するスラグ噴射用水中ポンプ９が内設されている。このスラグ噴射用水中ポンプ９は、水砕ピット１内の水砕水を吸い込み、ノズル（図示せず）を介して、落下してくる溶融スラグに流量約２００ｍ3 ／Ｈで吹き付け水砕化を促進する。
【０００８】
また、水砕ピット１内には、約１５００℃の溶融スラグの熱により高温化された水砕水を冷却するための冷却器７が内設されている。この冷却器７の構成は、例えば、蛇管方式のパイプ内部に常時３０℃前後の冷却水を１ｍ／ｓｅｃ程度の流速で流すようにしている。しかして、水砕ピット１内の水砕水の温度を約５０℃程度に維持している。また、冷却器７の近傍には、この冷却器７の冷却能力を向上させるため流速発生装置、例えば、水中ミキサー８が配設されている。この水中ミキサー８を作用させることにより冷却器７のパイプ隙間に水の流れを形成して冷却効果を向上させるようにしている。
【０００９】
なお、水砕水で急冷し水砕した水砕スラグは、水砕ピット１の底部に沈澱するが、沈澱した水砕スラグは、底部に設けられた、例えばスクレーパコンベア等（図示せず）により水砕ピット１から取り出される。一方、沈澱しない固形物も水砕ピット１内に留まるため、水面上に浮遊した状態で噴射用水中ポンプ９または水中ミキサー８での水流により排出側へ押し流され、最終的には、前記スクレーパコンベアに捕捉されて水砕スラグと一緒に水砕ピット１から取り出される。
【００１０】
【発明の効果】
以上述べたように、本発明にあっては、スラグを水砕処理する機能を全て水砕ピット内に集約したため、従来技術には必要であった水砕水排水の濾過器および水砕水貯留槽を必要とせず、かつ、水砕水冷却塔を独立して屋外に設置する必要がなく、その結果、そのための配管を必要としない非常にコンパクトな設備構成になった。配管がないということは、配管閉塞というトラブルからも開放されることになる。以上のように、関連装置やそのための配管を削減し、設備据付エリアを水砕ピット内のみにしたため、設備費、据付費、設備ランニングコストおよびメンテナンスコストが従来技術に比べて大幅に削減出来る工業的に極めて優れた効果を奏するものである。

BACKGROUND OF THE INVENTION
The present invention relates to equipment for melting waste in a waste melting furnace and hydrolyzing the generated molten slag.
[0002]
[Prior art]
The method for melting waste such as general waste or industrial waste is to put waste into a waste melting furnace together with auxiliary materials such as coke and limestone, take out the waste as molten slag, and granulate the molten slag. In the granulation process, the granulated water is circulated. FIG. 2 is a conceptual diagram of a granulated water circulation facility in a conventional waste melting process. As shown in this figure, the molten slag that has been discharged from the melting furnace at a rate of about once / hour is poured into the granulated pit 1 and rapidly cooled with granulated water to be granulated, and the granulated slag is precipitated. The precipitated granulated slag is taken out from the granulated pit 1.
[0003]
Granulated water is circulated and supplied to the granulated pit 1, and the granulated water drainage that overflows the granulated pit 1 is sent to the granulated
[0004]
[Problems to be solved by the invention]
In the above-mentioned granulated water circulation facility, the pipe from the granulated pit to the granulated water storage tank, the pipe from the granulated water storage tank to the granulated water cooling tower, and the return pipe are long, so the initial cost is high. In addition, constant maintenance is required to prevent sludge from clogging in the pipes. In addition, solid matter that does not settle in the granulated pit is contained in the overflowed granulated water drainage, causing clogging in the piping. In order to temporarily store the crushed water, a crushed water storage tank is required. Since the solid matter that has passed through the filter is also precipitated in the granulated water storage tank, naturally, equipment for removing them, that is, a scraper, a pump, and the like are required.
[0005]
In addition, since the granulated water cooling tower is installed outdoors, it is necessary to consider noise prevention, contamination due to splashed water on the building wall, and rust prevention tower. As described above, in the prior art, the initial cost and the maintenance cost are large in terms of equipment, and because there are many related equipment, the installation space for the equipment becomes wide, and the running cost for the operation also becomes large. There's a problem.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the inventors have intensively developed, and as a result, all the ability to granulate slag is aggregated in the granulation pit, resulting in a very compact equipment configuration, For this purpose, a slag granulation treatment facility for waste melting treatment in which the equipment installation area is only in the granulation pit is provided. The gist of the invention is that
(1) In a facility in which waste is pyrolyzed in a shaft furnace type pyrolysis melting furnace, and the discharged melt is granulated in a granulation pit, a submersible pump for slag injection and a pit are disposed in the granulation pit. A slag granulation facility for waste melting treatment, which is equipped with a cooler for granulated water inside.
(2) The slag granulation process in the waste melting process, characterized in that in the granulation facility described in (1), a flow rate generator for generating a flow rate is provided in the vicinity of the cooler in the granulation pit. In the facilities.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a conceptual diagram of slag granulation processing equipment in waste melting processing according to the present invention. As shown in this figure, slag injection for storing crushed water in advance in the pulverized pit 1 and cooling and pulverizing the molten slag falling from the melting furnace in the pulverized pit 1. A

In addition, the granulated slag rapidly cooled with granulated water and granulated is deposited at the bottom of the granulated pit 1, and the precipitated granulated slag is provided, for example, by a scraper conveyor or the like (not shown) provided at the bottom. It is taken out from the granulated pit 1. On the other hand, since solids that do not settle remain in the granulation pit 1, they are pushed to the discharge side by the water flow in the
[0010]
【The invention's effect】
As described above, in the present invention, since all the functions of granulating slag are aggregated in the granulation pit, the granulated water drainage filter and the granulated water storage required for the prior art are required. There is no need for a tank, and there is no need to install a granulated water cooling tower independently outside, resulting in a very compact equipment configuration that does not require piping for that purpose. The fact that there is no piping is also free from troubles such as piping blockage. As mentioned above, because the related equipment and piping therefor have been reduced and the equipment installation area is only in the granulation pit, the equipment cost, installation cost, equipment running cost and maintenance cost can be greatly reduced compared to the conventional technology. In particular, it has an extremely excellent effect.
